Title:Investment Cast Net Shaped Complex Lubricating Channels
Abstract:Producing complex net shape, narrow, long, and curved lubrication channels within the body of an investment cast article using controlled solidification investment casting (CSIC) process is a technically challenging problem. MER is proposing a novel technology to resolve the CSIC technical limitations by utilizing PolyCapillary material (PCM), an advanced powder metallurgy technology, to produce channel forming materials with tailorable mechanical and metallurgical properties to match and work with those of the target investment cast high purity aluminum alloy. The technologies have the advantage of producing large diameter tubes with micro porous walls that have a fraction of the base metal mechanical properties. Mechanically, the micro porous tubes will have the advantage of matching the shrinkage pattern of the investment cast Aluminum alloy. Metallurgically, the PCM process can produce tubes from different materials to eliminate cross contamination between the tubes and the aluminum alloy that can produce brittle conditions within the investment cast article near thin sections. Prefabricated channels produced via PCM will have the advantage of producing net shape complex lubricating channels within the body of an investment cast article with minimal impact on the CSIC process in terms of production volume and process cost. The PCM produced lubricating channels.

Title:Screech Suppression via Heat Release Modification
Abstract:Combustion stability is critical to the performance of augmented military jet engines. Instabilities such as screech can result in reduced augmentor performance, increased sustainment requirements, or even catastrophic failure. Screech remains a difficult problem to predict and mitigate, and its occurrence can limit the operational flight envelope of military systems. Many of the passive techniques used to suppress combustion instabilities in stationary gas turbines are unsuitable for military propulsion systems. Advanced active control techniques involving high-bandwidth active cancellation of instabilities have not been applied to real systems due to their inherent complexity. In this research program, we propose to apply an advanced fueling system for low-bandwidth, active screech suppression. The fueling system, called CFIS (Carbureted Fuel Injection Scheme), provides control of the spatial distribution of heat release, allowing for manipulation of symmetry and convective time delays in the augmentor without structural modifications. In the proposed research program, we will apply CFIS fueling to a high-fidelity augmentor rig designed to generate screech instabilities that are relevant to modern engine designs (transverse instabilities). We will then apply and investigate strategies for mitigating screech by manipulating the heat release distribution using CFIS injectors.

Title:Technologies for the Suppression of Combustion Instability or Screech
Abstract:This Phase I project will demonstrate how control of fuel and/or air distribution can be used to mitigate combustion oscillations. The project will be done with the perspective that the mechanism of controlling the oscillastions can eventually be implemented into a retrofittable, closed loop approach. It has been well established that the relationship between the location and timing of local heat release can couple with acoustic modes in the augmentor. Examples of exploiting this by pulsing fuel at the correct phase to mitigate can be found, but the requirements for the fast pulsing preclude practical implementation. In the proposed project, spatial movement of the heat release rather than temporal will be demonstrated through a combination of fuel and air placement. The effort will utilize an existing test rig with two- stream mixing to mimic the fan and core air streams. This offers the ability to explore manipulation of the oxidizer stream in addition to fuel placement as a migigating strategy. Complimenting the tests will be the development of analytical flame response transfer functions which will help interpret the reasons the control measures work.

Title:Technologies for the Suppression of Combustion Instability or Screech
Abstract:A novel passive screech liner damping design concept to damp out low and high order screech modes simultaneously in legacy, pipeline, and advanced military afterburners are proposed for development and demonstration in this SBIR project. The proposed novel passive damping liner design concept is very retrofittable and implementable in any current or future augmentor systems without adding complexity and weight to the system or requiring supplemental cooling air. The proposed screech liner hardware concept will be designed, computationally analyzed, fabricated, and tested in Phase-I and Phase-I option of this SBIR project by leveraging an existing augmentor instability /screech liner damping rig designed, fabricated, and utilized to excite a low order tangential mode and then attempt to attenuate it using the new concept.

Title:Rapid and Accurate High-Resolution Radar Signature Prediction of Sea Targets
Abstract:Radar signatures of small boats and ships are inherently complex due to their myriad topside features: railings, antennas, masts, ladders, armaments, pilot stations, outboard engines, storage bins, etc. In boats, the use of fiberglass and other radar-penetrable materials for hulls and decks further complicates the radar signature by exposing interior geometry. Radar detection, identification, and tracking of watercraft depends on accurately characterizing radar signatures and their variability over anticipated operating conditions. However, at these wavelengths, watercraft can span hundreds to thousands of wavelengths, well beyond the capability of any full-wave electromagnetic solver. Asymptotic (ray-tracing) solvers do very well at quickly predicting the signatures of large, complex shapes, but they suffer in capturing the effects of detailed features measuring a few wavelengths or less. Yet, these detailed features can play an important role in the overall radar signature. We propose to develop a practical signature prediction capability for watercraft that hybridizes the solution of two mature electromagnetic modeling technologies based on ray tracing and method-of-moments. Phase I will focus on hybrid formulation development and proof of concept through numeric experiments. In Phase II, hybridization algorithms will be refined and implemented in a radar signature tool, including a commercial-grade GUI.

Title:RARSP: Rapid and Accurate Radar Signature Prediction
Abstract:Modeling of radar signature of sea targets in dynamic sea states is a critically important problem in developing methods of detection and identification of potentially threatening ships. As most maritime radars operate at X-band, this EM problem has an extremely large electric-size and it is further complicated by the sea wave phenomena. Simulation tools exist for high-frequency electromagnetic (EM) simulation. However, existing tools are insufficient in following three aspects: incapable of modeling the fine features on the topside of ships which often have significant scattering contributions due to their comparable size to X-band wavelength; incapable of capturing the interaction between ships and complex sea states; not suitable for state-of-the-art Graphic Processing Unit (GPU) or GPU-cluster acceleration. We propose to develop a hybrid method based on the novel Bidirectional Analytic Ray Tracing (BART) algorithm and the 3D fast Method of Moments (MoM) algorithm. Besides the fine features of ships, the proposed tool can also take account of scattering of rough sea surfaces. Both BART and MoM can be accelerated by inexpensive GPUs.

Title:Rapid and Accurate High-Resolution Radar Signature Prediction of Sea Targets
Abstract:High-fidelity predictions of the radar cross sections of ships at sea at X-band and above are complicated by the presence of interactions between the important scattering objects on the ship, with sizes comparable to a few wavelengths, and the larger structures of the ship which are electrically large. Interactions with the ocean surface are also important. Different electromagnetic analysis techniques are required for the small and large structures, and so the use of a single technique will either be computationally prohibitive (in the case of full- wave techniques suited for small structures) or inaccurate (in the case of high-frequency asymptotic solutions for large structures). In the proposed Phase I project, we will use a hybrid technique that combines regions where a full-wave solver is applied with regions where a high-frequency solver is applied, overcoming the limitations of using a single technique for both. This work will build on a previous successful prototype of this basic concept for simpler systems involving only one small object, using Remcom's commercial XFdtd (full-wave) and XGtd (high-frequency) EM analysis software. After feasibility is demonstrated in Phase I, the prototype hybrid solver will be developed into a commercial product in Phase II.

Title:Real-time Mission And Path Planner (REMAPP)
Abstract:To maximize the strike effectiveness of multiple disparate manned and unmanned platforms’ while minimizing the potential damage to the strike force from the defenders in a high threat environment, we propose to develop REal-time Mission And Path Planner (REMAPP) that will provide secure routes of ingress and egress to designated targets. The generated routes will provide the necessary coverage from radar detection, identification and acquisition by enemy air defense systems by using the aircrafts’ active (e.g. self-protecting electronic countermeasures, standoff jammers, other SEAD measures) and passive techniques (terrain masking) of radar avoidance. Moreover, when a new threat is detected by on-board or off-board sensors, REMAPP will re-plan in real time increasing the survivability of the strike force. The proposed approach will be centered around Linear Temporal Logic (LTL) which is a very powerful specification language that provides a very natural way to model the rules of engagement and multi-platform coordination and Rapidly-Exploring Random Trees (RRTs) that are suitable for a real-time path planning in complex, high constrained environments. REMAPP will benefit from mission specifications expressed in very general forms, combining and recombining information to pursuit myriad purposes which is extremely important for dynamically changing environments such as pop-up threats.

Title:Automated Target Area Threat and Route Optimization
Abstract:This effort will develop a software tool with the ability for near real-time threat and target area routing and de-confliction capability. Through the use of innovative algorithms based on reactive-navigation, extension of Genetic Algorithm work, and software architecture it will optimize the performance of multiple platforms by increasing survivability and increasing probability of kill in a dynamic, high threat environment. The design will be robust enough to accommodate platform enhancements, onboard/offboard jamming, reactive Suppression of Enemy Air Defense measures, and minimize strike platform exposure.The proposed development builds upon BeemmLink – the software framework for modeling, simulation, visualization, and analysis of dynamical systemsThe proposed effort will result in the proof- of-concept implementation of functionalities for asset allocation and path-planning/motion- planning. We will determine minimal acceptable asset packages that maximize the probability of reaching their designated targets, and use these elementary packages for constructing viable asset groups. These implementations will demonstrate that BeemmLink is capable of efficiently handling the required computational complexity of algorithms commonly used in the context of mission planning.

Title:Team Oriented Programming for Dynamic Automated Target (TOPDAT) Area Threat and Route Optimization
Abstract:This proposal is to develop Team Oriented Programming for Dynamic Automated Target (TOPDAT) Area Threat and Route Optimization. TOPDAT will dynamically plan and update air vehicle routes and response to threats in real-time for teams of manned and unmanned air vehicles on complex missions in hostile environments. The core challenge is to determine the optimal strike routing and utilization of limited defensive resources to de-conflict and protect air vehicles and thereby maximize mission success in a complex and changing threat environment. TOPDAT will apply a proven, state-of-the-art algorithm for planning for coordinated manned and unmanned assets. TOPDAT will use the concept of Team Oriented Plans to structure the overall activity and then use planning algorithms to work out the details. The planning algorithm works by iteratively planning for each asset individually, looking for interactions between the plans - and then replanning - taking into account the identified interactions. The result is an efficient algorithm that finds high quality coordinated plans for many assets. Due to the heterogeneity of the assets and the situations they face, we will use a suite of planning algorithms to do the planning for individual assets, with the right algorithm chosen for the situation with intelligent meta-reasoning.

Title:Advanced Wireless Maintainer Communications in Electromagnetically Noisy Environments
Abstract:Navy aircraft operate from and in these highly dynamic environments with many people performing various tasks, such as ordnance loading, hot fueling, recovery of equipment and personnel, and multiple in-flight mission operations. Mission success requires a high level of coordination and communication. This research is designed to advance the state of the art in wireless communications aboard ship by developing a usable Visible Light Communications (VLC) system to provide high bandwidth, reliable communications for maintainer to maintainer and maintainer to aircraft communications. The system will be encryption capable and, because of the unique nature of VLC, will be difficult to intercept and jam in the operational theatre. Further, by avoiding traditional RF, the system will be safer in and around environments in which stray RF energy can be hazardous. `

Title:Ultrasonic Communication System for Noisy Environments
Abstract:Safe efficient operations on the flight line or on the deck of an aircraft carrier require effective communications between members of the crew and between members of the crew and the aircraft pilot. Maintainers working on the flight deck or flight line are often subject to extremely loud noise fields (110 to 140 dBA), which makes natural voice communications challenging or impossible. Missed communication and miscommunication are a constant risk, either of which could imperil operational tempo or crew safety. A new solution is needed to enable high-reliability communications between personnel on the flight deck and flight line. Creare proposes an ultrasonic communications system to enable voice and data communications for maintainers on the flight deck and flight line. In Phase I, we will develop the core technology and overall system architecture. In Phase II, we will design, fabricate, and test the system and deliver prototype units to the Navy.

Title:Direct Conversion DRFM
Abstract:Recent advancements in high speed signal processing technology offer the possibility for significant efficiency of Electronic Attack (EA) Digital RF Memory (DRFM) systems. Typical DRFM technology utilize an RF translation to baseband, Radio Frequency (RF) sampling, storing digitized samples into memory and then reversing the process to reconstruct the RF signal prior to transmission to the victim radar. This allows for both time domain and frequency domain manipulation of the radar signal. Direct Digital conversion of RF signals has the potential to reduce DRFM size, power consumption, and unit cost and allows for a multiple parallel DRFM architecture capable of addressing emerging threat environments. SPEC’s proposed Direct Conversion DRFM (DCD) approach provides an optimized combination of direct digital RF up and down conversion from 2-18GHz, broad band DRFM performance, and multi-channel DRFM threat EA capability in minimum size, weight and power (SWaP). The direct conversion concept is based on Nyquist sampling and the use of passive anti-aliasing filters to cover a very wide frequency range with no active RF components required for up or down conversion.

Title:Direct Digital Radio Frequency (RF) Conversion Digital Radio Frequency Memory (DRFM)
Abstract:Systems & Technology Research (STR) with our partner Mercury Defense Systems (MDS, formerly KOR Electronics) present this proposal for developing new Digital Radio Frequency Memory (DRFM) technology. The combination of STR’s proven low size weight and power (SWAP) high performance receiver and digitizer technology with MDS’s leadership in DRFM technology will provide both innovation and experience in pursuing the proposed technology development.DRFM systems are an important tool in EW applications. The ability to use them on SWAP limited platforms while increasing their performance metrics is an important goal for future EW capabilities. The goal of this proposed effort is to develop an advanced all digital Electronic Attack (EA) DRFM system minimizing Radio Frequency (RF) component technology that will result in reduced size/cost/complexity and increase capability and effectiveness through wider bandwidth. Specifically we will explore Direct Digital RF Conversion approaches that eliminate the RF signal translation modules of conventional architectures. This direct digitization of RF signals will cover input frequencies between 2 GHz and 18 GHz. This is expected to reduce size and power requirements by significant margins. The per unit price reduction would allow for multiple parallel DRFM architectures capable of simulating emerging threats to US radar systems.

Title:High Gain Common Data Link (CDL) Antennas for Networking UAV Nodes
Abstract:In this Phase I effort, FIRST RF will develop and evaluate concepts enabling highly directive multi-beam TCDL communications using phased arrays integrated on the Fire Scout UAV platform. Phased array systems allow for dynamic beam steering with graceful degradation. Wide elevation patterns desirable for air-to-air or air-to-ground communications are achieved by using a linear array topology. These arrays also have the benefit of a narrow azimuth radiation pattern conducive to point-to-point communications and networking waveforms. Highly selective filters isolate TCDL uplink and downlink channels and allows for multi-beam functionality as well as the ability to simultaneously transmit and receive on each channel. FIRST RF proposes an innovative approach that leverages innovative phased array architecture to provide a highly functional TCDL communications node with multi-beam capability. Commercial applications of this technology have also been identified.

Title:High Gain Common Data Link (CDL) Antennas for Networking UAV Nodes
Abstract:Unmanned Air Vehicles (UAV) such as Fire Scout could increase its utility to the fleet by operating as a node in an airborne star network. Such a system would need to support full- two way communication with up to six other nodes for transfer and relay of data, imagery, command and control with 360 degree coverage, within a 110NM UAV slant range. This would require multiple high-speed channels.The Phase 1 base effort will concentrate on first developing a complete set of system requirements from tops down system analysis. Innovative AESA concepts will be synthesized and feasibility determined. Risk/Reward trades will be accomplished on multiple AESA approaches to select candidate approach that can meet the derived system detail requirements.

Title:Graphics Processing Unit (GPU) Acceleration for Cosite Interference Prediction Tools
Abstract:Simulation tools that exist today for prediction of cosite interference in complex RF environments are able to accurately model complex platforms but they are quickly constrained by computational limits on traditional workstations. The focus of this research will be on updating existing electromagnetic interference and vulnerability (EMI/EMV) simulation tools to the latest parallel computing clusters. As a result of this effort the time required for analyzing cosite interference on complex platforms will be significantly reduced. ANDRO will build upon its existing E3Expert framework and integrate a new EM analysis tool, uCAST (UTD Complex Antenna Simulation Tool). uCAST is a UTD (Uniform Theory of Diffraction) based code developed by Applied EM, Inc. that is currently being enhanced with parallel processing capabilities under a related NAVAIR SBIR Phase II activity. As part of that effort bottlenecks in current algorithms were identified as well as other algorithms which may be problematic in transferring to a parallel environment. That work proceeded into Phase II where a commercial grade GPU based code was developed using NVIDIA’s CUDA platform. In this Phase I effort we will assess the feasibility of integrating the uCAST kernel into the E3Expert and develop a work plan for building requirements to test and prototype its interface. During Phase II we plan to develop a commercialized version of E3Expert built with uCAST’s UTD based parallel processing capabilities for cosite analysis.

Title:Graphics Processing Unit (GPU) Acceleration for Cosite Interference Prediction Tools
Abstract:Modern military systems contain numerous avionics and electronic systems that must perform to very high standards in hostile environments in the presence of numerous potential sources of electromagnetic interference (EMI). On airborne platforms for example, there could be dozens of RF systems radiating and receiving mission critical signals simultaneously over a very wide range of frequencies. Undesired electromagnetic coupling between these systems can easily occur, leading to loss of function of one or more critical systems. In addition to this cosite interference, there is also the potential for EMI due to sources of electromagnetic energy not located on the platform of interest. These sources of external interference could be due to systems operating on nearby platforms such as a high power radar on a ship, or could be due to intentional jamming. In order to ensure maximum likelihood of mission success, modern military platforms must consider the mitigation of cosite and inter-system EMI prior to deployment, whenever subsystems are added or changed, and periodically during the service life of the platform to ensure continued compliance as the equipment ages.Through this proposed effort, we will show how the GPU-based parallelization of EMIT will lead to significant reductions in simulation time, greatly improve the usability of the tool, and make it possible to add higher-fidelity modeling formulations without sacrificing run time or decreasing the efficiency of the cosite engineers.

Title:Low SWaP Wideband Digital Receiver/Exciter (DREX) for Multifunction AESA
Abstract:Next Generation airborne Navy Radar and Communication Systems will continue to rely on and evolve Active Electronically Scanned Array (AESA) systems to have more digitized channels for the flexibility of advanced digital beamforming (DBF), Space-Time Adaptive Processing (STAP), and agile wideband waveforms including Multiple-Input Multiple-Output (MIMO) techniques. These evolutionary requirements all lead to the need for more Digital Receiver/Exciter (DREX) modules, but proliferating them on most platforms has historically not been possible due to the Size, Weight, and Power (SWaP) and Cost (SWaP-C) profile of existing solutions. Azure Summit is pleased to offer this proposal to NAVAIR in which we leverage our existing efforts for the Missile Defense Agency (MDA), NAVAIR, and Azure IR&D in DREX technology. Azure has a miniature wideband DREX module running in the lab today. Azure will leverage these technologies to develop 1 GHz wideband DREX concepts for NAVAIR in the 2-18 GHz band that support next generation AESA with full flexibility for improved radar modes, communications, SIGINT, EW, and other shared aperture concepts, and with low SWaP-C to enable doing this cost-effectively at the system level.

Title:Low Size Weight and Power (SWaP) wideband Digital Receiver Exciters (DREX) technologies for Radar and Communication Systems
Abstract:FIRST RF will develop a low SWaP DREX system approach that will include a wideband, multichannel frequency conversion capability. Requirements and design viability for a flexible multi-mission system that can support advanced radar modes or high-bandwidth communications will be investigated. FIRST RF will also pursue an innovative DREX integration approach with the rest of a sophisticated phased array system. This integration approach seeks to minimize system SWaP by eliminating redundant enclosures, cabling, and thermal management systems. The resulting system will be low-profile, air cooled, and contain all necessary structural, RF, environmental enclosure, and DREX subsystems required for a next generation sensor. The successful completion of this program will allow naval airborne assets to have unprecedented capabilities for operating in a variety of ISR and force protection roles.

Abstract:Mustang proposes to develop innovative, low Size, Weight, and Power (SWaP) Digital Receiver Exciter (DREX) technologies needed for simultaneous operation of the U.S. Navy Fire Scout Radar Autonomous Collision and Avoidance System (RACAS) and Coherent Automatic Radar Periscope Detection and Discrimination (C-ARPDD) modes. The design will also support the integration of multiple Radio Frequency (RF) applications that have historically been treated as separate systems (such as Communications, Navigation, and Electronic Warfare) with lower overall SWaP and cost requirements.This concept is a next-generation DREX design with improved SWaP for a C-Band (5250-5900 MHz) radar and communication array. A binary phase or frequency shift keying communication waveform using the HAD-DREX hardware will be applied. We will show how our design is capable of generating highly complex adaptive transmit waveforms such as radar waveforms with spectral transmit notches and Orthogonal Frequency Division Multiplexing (OFDM) waveforms for communications applications. Included will be the benefits of our tightly coupled FPGA-Digital Signal Processor (DSP) solution that enables a substantial amount of signal processing to be performed directly in the DREX, which greatly simplifies the interface to the platform general purpose processor while providing a highly adaptable antenna interface.

Title:Optical Inertial Reference Unit for Navy Tactical Airborne High Energy Laser (HEL) Applications
Abstract:SA Photonics is pleased to propose our FALCON Optical Inertial Reference Unit (OIRU) for use on High Energy Laser (HEL) weapon systems on tactical air platforms. The inertially stabilized Optical Reference Beam (ORB) provided by an OIRU serves as a “virtual star” and is a key element in the jitter control system of aircraft-hosted optical systems. The low- frequency band of the IMU signals below the band used to stabilize the ORB can serve as an angle reference during target acquisition slews. Present state-of-the-art OIRUs are too large for tactical use, and are susceptible to linear vibrations. The FALCON OIRU, based on SA Photonics fiber optic gyro (FOG) technology, addresses the size and vibration issues of the aircraft-hosted tactical HEL application. The FALCON OIRU can be packaged in a 2 inch cube, and provides high sensitivity and low errors required for dual use as a jitter control virtual star and as a low-frequency IMU angle reference.

Abstract:Veraphotonics proposes to develop a low weight, high-speed structural health monitoring system capable of measuring load, vibration, and acoustic emission (AE) responses corresponding to damages occurring in advanced materials and structures. Our novel sensing system consists of a fiber bragg grating (FBG) sensor array interrogated by a low- cost, light-weight, low-power miniaturized stand-alone laser based detection system combined with state-of-the-art multichannel wireless data acquisition node and high- performance energy harvesters.

Title:Wireless and Passive Noise Measurement and Earplug Evaluation System
Abstract:To address the Navy’s need for a miniature wireless earplug-integrated sensor, Physical Optics Corporation (POC) proposes to develop a new Wireless and Passive Noise Measurement and Earplug Evaluation Sensor (WIPAS) system This system is based on an innovative surface acoustic wave (SAW)-based passive and wireless pressure sensor and an acoustic sensor that is small enough (2×2×4 mm) to be inserted in and removed from the ear canal. These sensors wirelessly interface with the WIPAS system’s compact external interrogator unit. The WIPAS system works both as an earplug fit/performance evaluator and as a noise dosimeter. The innovations in the WIPAS system allow evaluation and measurement in real time without compromising the earplug, which is currently impossible. Unlike the conventional earplug whose performance typically degrades over time (due to movement, etc), the features offered by the WIPAS enable reliable determination of protection provided to the device wearer. In Phase I, POC will perform modeling and simulation of the SAW sensor, and demonstrate WIPAS feasibility by developing a limited-capability bench-top prototype. This TRL-3 prototype will be experimentally evaluated in laboratory-controlled environment. In Phase II, we plan to build and validate a complete TRL 5-6 system, demonstrate its field worthiness, and evaluate its productization.

Title:Earplug-Integrated Miniature Wireless Sensors for Warfighter Monitoring and Earplug Evaluations
Abstract:The objective of the proposed program is to develop a highly miniaturized wireless pressure sensor for integration with commercial off-the-shelf (COTS) earplugs in a practical and cost effective manner. The most immediate application is the evaluation of earplug performance, specifically with regards to the important issue of middle ear pressure equalization and the risk of eardrum rupture among pilots undergoing rapid ascent or descent. More generally, the ability to integrate highly-miniaturized wireless sensors into the distal portion of a COTS earplug (e.g. that portion proximal to the middle ear) would make it practical to continuously monitor a wide variety of physiological parameters during military operations.

Title:Universal In-Ear Warfighter Monitoring System (1001-956)
Abstract:Job related hearing loss is a growing issue within active and retired military personnel. Ear protection is critical to prevent such injury, but personnel in variable pressure environments, such as pilots, often cannot use the best hearing protection due to pressure changes risking barotrauma. Current physiological monitoring systems can measure in-ear pressure levels, but require customized ear pieces. The proposed solution will use recent developments in pressure sensing and small, wireless near field communication electronics to provide a simple, universal system that can be used to measure the in-ear pressure of any subject wearing any earplug. The Triton In-Ear Warfighter Monitoring System will measure in-ear pressure levels of subjects wearing their own personal hearing protection in simulated pressure scenarios, ensuring that personnel are not exposed to a dangerous level of pressure while affording them the best hearing protection possible.

Title:Terahertz Detection of Composite Heat Damage
Abstract:In this Phase I SBIR project, we propose to demonstrate the feasibility of a Time-Domain Terahertz (TD-THz or THz) system for rapid determination of the composite heat damage to airframes. The method employed will be capable of inspecting for heat damage underneath paint and coatings to detect hidden and early-stage degradation of the composite. We will experimentally investigate a BMI based composite before and after heat damage, and compare THz to other inspection methods for determining changes in the composite characteristics. The proposed method will be able to measure these properties on a wide variety of composite systems with a remotely positionable sensor. The sensor will be suitable for hand-held single point measurements; and adaptable to robotic or gantry scanning of large area regions. The reflection T-Ray sensor will have non-contact operation, with working distances adjustable from less than 1 cm up to 10 cm. Measurement will be real time, with waveforms acquired at rates up to 1000 Hz, allowing large areas to be scanned.

Title:A Lightweight Optical Approach to Detect Incipient Heat Damage
Abstract:Composite materials, widely used in aircraft, reduce manufacturing cost, improve structural performance, and boost fuel efficiency. However, composites are susceptible to hidden heat damage, which may occur from fire, exhaust impingement, overheating, or during repairs. The earliest heat damage stage, referred to as “incipient” heat damage, may reduce upper use temperature, cause matrix mass loss, and reduce mechanical flexural strength. We propose an innovative approach that detects this very early matrix damage via changes in the mechanical flexural response of a structure. We use a small lightweight optical imaging detector that can rapidly monitor large structures and identify regions exhibiting incipient heat damage. We combine small mechanical excitation of the structure under test with a lightweight camera that images the surface resonant frequency, directly probing the local flexural strength of the composite material. This technique, called the Fast Imaging Non- Destructive Inspection Technique (FINDIT), can directly and nondestructively test the mechanical flexural properties of composite material. Flexural damage has been shown to provide a first warning of incipient heat damage before visual manifestation. FINDIT quantitatively measures the associated tilt-tip surface changes, and may be automated, removing subjective judgment factors, rendering the approach fully functional under adverse circumstances.

Title:Innovative & Lightweight Cargo/Personnel Handling System (1001-953)
Abstract:The US Navy seeks to simplify loading, unloading and reconfiguring (between cargo & passenger missions) the C-2A aircraft with a view to reducing both operator stress and deck residence time during carrier flight operations. Triton Systems, Inc, proposes to meet this requirement using a combination of proven cargo/seat handling equipment designs and lightweight materials to offset any weight increase associated with the new cargo/seat handling hardware. A roller system will be used to load both cargo and seats including a removable roller system with quick-release attachment hardware for the ramp. The roller system design will be compatible with existing C-2 seat and floor tracks. This provides the Navy the option to avoid a costly requalification program for a new seat design (mindful of the fact that the C-2 seating must withstand catapults and traps) while leaving the door open for a possible new seat design in the future. A new cargo cage design will be explored that will a) take fuller advantage of the available cargo space (particularly overhead) than the current design , and b) include consideration of various options to reduce cage weight through the use of lightweight composite materials and/or parts consolidation.

Abstract:TAF Proposes to implement a cargo and passenger handling system for the C-2A(R) consisting of foldable seats and a cargo roller system that will improve the speed, agility, and flexibility of fleet logistics support operations. The seats will fold against the sidewalls of the aircraft with a one-touch latch operable in less than 30 seconds per seatpair. The seats and cargo rollers will be attached to the existing seat rails with quick-click hardware allowing removal from the aircraft when needed. The complete cargo and passenger handling system will weight less than the existing seats. The foldable seats will be rated to 20G+ emergency loads in both the folded and in-use positions. The benefits of this system include reduced time required onboard carriers, minimized crew effort, eliminated need for hand-loaded cargo, improved crew member safety, and reduction of seat removal from the aircraft. Commercial applications include commercial mixed cargo and passenger flights in remote areas, other military aircraft, and mid-sized business jets.

Title:Fiber Optic Bi-Directional Amplifying Repeater
Abstract:Telecommunication 850 nm band is an attractive choice for the physical layer and has been used for the vast majority of the optical local area networks (LANs) by taking advantage of comparatively low-cost silicon P-I-N technology for optical receivers as well as high power GaAIAs semiconductor lasers for both the signal sources and the amplifier pumps. For a fiber optic link to connect the aircraft network to an external pod through a pylon, a fiber optic repeater with amplification is needed to compensate the loss of the link caused by the power division by the multiplicity of directional couplers and the propagation loss of the transmission fiber. A fiber optic amplifying bi-directional repeater to boost optical (digital) signals bound for hardpoint pylons is thus highly demanded for optical power loss budget on military aircraft. We propose to develop compact fiber amplifiers in the 850 nm band satisfying the requirements of next generation LANs. New glasses and fibers will be developed for building amplifiers near 850nm.

Title:Fiber Optic Bi-Directional Amplifying Repeater
Abstract:The Navy needs an optical repeater based upon the NGCON (MIL-PRF-64266) because the optical power loss budget on military aircraft is demanding. A bi-directional optical amplifying repeater would address the optical loss issue of connecting a fiber optic link in the aircraft network. Challenges include meeting the requirements for shock and vibration, operating temperature range, and optical port flexibility supported by the NGCON connector family. A design that enables the number of fiber ports required presents a major challenge to any optical repeater technology when size, weight, and power are considered. To address this, Vega Wave Systems and Illum Technologies will design an NGCON-based fiber optic repeater utilizing Illum’s patented Ferrule-Pak technology that is 5x smaller than the smallest commercially available transmitter/receiver optical subassemblies.

This material will be capable for application as a powder coating or consolidated and adhered inner cylinder for use as the bearing’s self- lubricating liner. The material will exhibit state of the art contamination resistance while minimizing additional friction or cost. Additionally, the material will not increase initial torque on the system nor operating temperature. The result will be a bearing system with increased lifetime compared to current technologies.

Title:Life Improvement of Plain Airframe Bearings by Preventing Contamination
Abstract:Safe, Inc. proposes a physical shield to protect spherical bearings from the abrasive particulate. Since many rotorcraft rod-ends are installed in exposed locations, sand and dirt cause damage to the spherical bearings and their liners. By preventing these particulate from contacting the spherical ball, the shield will prevent much of the contamination damage that shortens bearing life on rotorcraft. By allowing inspection without removal or with partial removal, the shield will further reduce maintenance requirements. Incorporation of the shield concept into future bearing production can lead to increased shield life and further reduce costs.Safe’s strategy is to select a shield material that will minimize heat build-up due to hysteresis and also enable heat dissipation for whatever heat is developed due to flexure. The shield material will be selected for inherent temperature resistance and in particular, a material that is chemically stable will be chosen. In order to minimize the weight and volume of the bearing shield, Safe has created a concept which remains close to those bearing surfaces which require protection. This design strategy will minimize the impact of the shield on the assembly weight, on the flexural resistance, and on the overall bulk of the assembly.

Title:Polarization Insensitive Diffraction Grating
Abstract:The intent of this proposal is to design, and later fabricate, a non-polarizing diffractive beam combining device which meets the stringent requirements of a fiber-laser based Laser Weapon System (LWS). The diffractive beam-combiner is a key element in the system in that provides for combining several high power lasers which differ in wavelength by ~ 5nm into a single beam without suffering wavefront distortion due to thermal absorption of the laser. Recent improvements in both fiber lasers and in laser diodes have made compact and power- efficient systems possible, but all depend on a diffractive beam combining device to achieve required power levels. The existing technology of Multilayer Dielectric Reflection Gratings (MLD) developed for high power laser pulse compression will be used to develop the non- polarizing beam combiner gratings. The requirements as outlined in the announcement are stringent and include 1) High power handling capability, 2) High Diffraction Efficiency over a 40 nm bandwidth, 3) Polarization insensitivity, 4) Low absorption. Additionally, PGL has been informed that a lower dispersion device with a larger grating period is preferred for most applications. These are all challenging requirements but they may be best met with the proposed MLD type gratings.

Title:High-Efficiency Polarization-Insensitive Diffraction Grating for All-Glass Monolithic SBC Fiber Laser System
Abstract:Spectral beam combination (SBC) of fiber lasers is the most practical approach to DEW- class HELs using diode-pumped fiber lasers. Use of conventional diffraction gratings to combine wavelengths is limited in that metal is inherently absorbing. Regardless of the metal layer thickness, optical power is absorbed in the grating, altering the spectral and efficiency properties of the grating and inducing optical aberrations that reduce beam quality. Designed to overcome the peak-power damage limitations for use in petawatt (short-pulse) lasers, multi-layer dielectric (MLD) diffraction gratings are essentially transmission gratings paired with a dielectric mirror stack. Although the lack of metallic surfaces exist eliminates absorption issues, MLD gratings by definition rely on interference within the stack, resulting in much higher intensities within the stack and leading to optical damage at reduced power levels.We propose to use an all-glass diffraction grating whose high efficiency is yielded by inhibiting transmitted orders, and can therefore be made of a single material with no coatings or layers. Used in an immersion topology, this grating allows for a fully monolithic SBC fiber laser system to be realized, with no free-space components. The grating and the monolithic SBC sytem re-design are the focus of the Phase I proposal.

Title:Decoupled Rendering Channels to Reduce Logistical Support Spares Requirements of Large Scale Training Centers.
Abstract:Diamond Visionics proposes a solution to decouple rendering channels from simulators and displays by developing a novel architecture consisting of both hardware and software. Modern video processing and networking techniques will be utilized such that any display in the system can be connected to any image generator in the system during runtime. This type of separation will allow for specific image generator tasks to be offloaded from specific rendering channels as desired to create higher fidelity simulations. Source data necessary for the image generators will not be limited to just the image generator computer, but rather a centralized location. These steps above will make it possible to reconfigure any image generator channel to any display very quickly during runtime if there should be a hardware failure. In an era where simulators are used more than ever, tremendous cost savings can be realized by virtually eliminating simulator downtime due to image generator failures.

Title:Non-Mechanically Moving Solar Directing System for Photovoltaic Modules
Abstract:The benefits of concentrated photovoltaic (CPV) systems with regard to total system efficiency are well known in commercial applications and operate at system efficiencies near 30% with some demonstration systems operating above 40%, compared with 15-20% peak efficiency for conventional PV. Because CPV systems must maintain alignment with the sun to maintain optical concentration, they harvest more energy throughout the day compared with non-tracked PV. Furthermore, because CPV systems use a fraction of the PV material required in conventional solar arrays, they have the potential to produce energy at a lower total cost. However, the operation and maintenance requirements and associated costs make traditional tracked systems unattractive for many customers. To address this challenge, Nanohmics proposes to develop and demonstrate proof-of-concept for its SunPerch™ flat form-factor concentrating photovoltaic system, which integrates concentrating optics, use of advanced triple junction PV materials, and zero-wear in-panel tracking in a cost-effective package made from conventional materials and using proven manufacturing technologies. This combination of innovations delivers the benefits of high-performance CPV systems in the same form factor as fixed-tilt conventional PV systems.

Title:Non-Mechanically Moving Solar Directing System for Photovoltaic Modules
Abstract:We propose a two-layer anti-reflective coating (ARC) that will have omni-directional properties. This coating will guide the light that is incident from oblique angles and orient it to become perpendicular to the solar cell surface. The top-most part of the coating will have a graded index of refraction, starting from an index of 1 at the air interface and gradually increasing to an index of about 1.5 at the interface between the two coating layers. This top layer will be made out of cheap polymer that can be deposited by dip-coating, and the graded index will be achieved by texturing the polymer to have up-right pyramids. As the light travels through this layer, it will bend to become perpendicular to the surface of constant index regardless of initial angle of incidence. The bottom layer of our proposed coating will consist of a standard silicon nitride (SiN) thin film layer that will act as an interference ARC between the polymer and the silicon surface of the solar cell to minimize reflections between each layer. We believe this approach offers cost and weight advantages over not only current mechanical solar directing systems, but also other similar graded ARCs based on silicon oxide.

Title:Non-Mechanically Moving Solar Directing System for Photovoltaic Modules
Abstract:A key focus of the United States government’s energy policy is to develop technologies that will allow the country to reduce Green House Gases by 80% by 2050. In support of this effort, the US Secretary of the Navy has developed a set of energy goals which include producing at least 50% of shore-based energy requirements using alternative sources primarily solar power. One of the largest ongoing expenses related to solar energy is maintenance required to support mechanical tracking systems. We have developed two thin film technologies that are capable of revolutionizing solar cell technology by capturing additional light without the need for the additional upfront and on-going expenses associated with mechanical tracking systems. In our proposed approach, two sets of thin film layers act in concert to increase the amount of light reaching the solar cells. The first thin film improves light collection at multiple solar positions using Holographic Optical Elements. The second thin film layer is composed of a composite polymer material that shifts the frequency of the incoming solar radiation from the UV and blue regions of the spectrum into the blue-green and green regions of the spectrum where the solar cells generate electricity considerably more efficiently.

Title:High Energy and Power Density ALD-Enabled Devices
Abstract:Envisioned Navy applications ranging from shore-based microgrids to directed energy weapons pose energy storage performance, cost, and scalability requirements that far exceed the capabilities of today’s technologies. Electric double-layer capacitors (EDLC) can meet most power demands ($/kW and kW/L) but cannot be used where high energy density is also required. As such, there is a need for a new electrochemical technology that can meet both high-energy and high-power demands using cost-effective materials. To address this need, ADA Technologies, Inc. (ADA) proposes to partner with PneumatiCoat Technologies, a leader in scalable atomic layer deposition (ALD) coatings, to develop an EDLC with high surface area nanocomposite electrodes modified with high dielectric constant metal oxide coatings. The resulting device will be readily scalable, consist of low-cost components, and be effective for tens of thousands of cycles across a wide operational temperature range.

Title:High Energy and Power Density Electrical Energy Storage Device
Abstract:Energy storage is an issue for high energy and high power applications. Batteries typically offer high energy densities with low power densities. For capacitors, the energy to power ratio is reversed. Therefore, capacitors have been limited to pulsed power applications that require high charging/discharging rates. Conventional ultra capacitors used in power applications are based on liquid electrolytes and the formation of electric double layers. However, these suffer from temperature limitations and have low energy densities.A high energy density / high power density capacitor would reduce/eliminate dependency on chemical batteries. High performance Ultra Capacitors would be of broad interest for grid storage/stabilization, directed energy weapons, rail guns, commercial hybrid/electric vehicles, space vehicles, and a vast array of portable electronics. Advanced Ceramics Manufacturing (ACM) believes high energy density / high power densities can be achieved by exploiting effective medium design concepts to allow energy densities to approach or exceed those of chemical batteries. If successful, the proposed technology will offer superior safety, lifetimes, and thermal stability compared to electrolyte based capacitors.

Title:Development of High Energy and Power Density Solid State Supercapacitors
Abstract:Many military and commercial applications have turned to power electronics to run a variety of systems efficiently, quietly, cheaply, and precisely. Therefore, there is an urgent need for efficient energy storage systems with both high energy and power densities. Supercapacitors have gained substantial attention for these applications since they offer outstanding advantages over conventional capacitors and batteries such as storing energy longer, discharging faster, longer shelf life, and excellent reversibility. However, current commercially available supercapacitors usually have a specific energy density of less than 10 Wh/kg, which becomes the limiting factor in system design and many applications. nGimat proposes to develop new solid-state supercapacitors based on solid state electrolytes and graphene based electrodes. The graphene will be processed to significantly increase the effective surface area and decorated with oxides to introduce additional psudocapacitance and increase permittivity. These supercapacitors have the advantages of high specific energy density, power density, operating voltage, cycling stability, chemical density, and charge-discharge rate based on the significant enhancement of electric double layer capacitance, psudocapacitance, permittivity, and operation voltage. Therefore, the proposed supercapacitor energy storage devices will enable a significant overall improvement in future power electronics systems enabling new military and commercial capabilities.

Title:High Energy and Power Density Electrical Energy Storage Device
Abstract:Naval Facilities Engineering Command (NAVFAC) has need for a robust stationary electrical energy storage (EES) device with the best properties of both rechargeable batteries and electrochemical ultracapacitors; having energy density of 500 W/l, ability to deliver high power pulses of 5 kW/l, and capability to achieve 25,000 full depth of discharge cycles. There is also an emerging need for improved EES technology in the commercial electric power industry, where it is needed for integrating with variable output renewable sources such as wind and solar, and for both distributed and centralized siting in support of a more efficient and smart electricity generation and distribution grid. TIAX proposes to develop such an electrochemical EES device meeting the above energy, performance and life metrics. TIAX has already demonstrated the inherent ability of advanced active materials to deliver the levels of performance required in such a hybrid device, and the proposed program will demonstrate feasibility of developing an energy storage device that incorporates these materials to deliver that performance, and to do so with technologies that will yield manufacturing cost of less than $500 per kWh.

Title:Underwater Tracking System for Accurate Horizontal Directional Drilling
Abstract:Addressing the Navy’s need to develop an accurate underwater tracking tool for Horizontal Directional Drilling systems, Physical Optics Corporation (POC) proposes to develop a new Underwater Tracking System (UNTRAS), based on implementation of tunable ELF transmitters. The system comprises two battery-operated units: diver operated handheld detector (HHD) and beacon ELF transceiver (BETR) that is placed inside the drill head (into the standard beacon housing). BETR’s receiver remotely receives command signals from the HHD in order to emit different ELFs/ELFs combinations for drill head tracking. BETR’s transmitter serves to emit optimal ELFs/ELFs combinations to track a drill head. The HHD incorporates low SWaP ELF receiver based on POC’s magnetic field processing modules and ELF command transmitter to remotely control the BETR to generate frequencies required for tracking. In Phase I, POC will develop UNTRAS design concept, perform detailed frequency domain analysis and modeling to identify optimal frequency/set of frequencies for accurate underwater drill-head tracking. Based on the design concept developed, POC will assemble a scaled-down UNTRAS laboratory prototype for testing. In Phase II, the UNTRAS design will be further refined and optimized, and POC will build a full-scale system prototype and create its test plan in a near relevant environment.

Title:Next Generation Boat Hull Impact and Abrasion Proofing
Abstract:Resodyn Corporation proposes to develop a single tough thermoplastic polymer coating material and system solution for aluminum and composite boat hulls. The coating functions as an adhesive for attaching doubler plates. It encapsulates and prevents water from corroding metal substrates plus it is hydrophobic and can include corrosion inhibitors and colorant. Basic polymer components are tough thermoplastics which are intrinsically impact resistant and abrasion resistant. Thermoplastic coatings are field repairable using a heat gun. No solvents chemical mixing is required. Technical work entails procuring aluminum and composite test specimens, formulating several different coating materials, test and evaluation. Programmatic work will compare the proposed solution to current practice and estimate a cost benefit to the government. A preliminary experiment and extending Resodyn Corporation’s existing Polymer Thermo Spray technology suggests a high likelihood of success.

Title:Craft Hull Impact and Abrasion Resistance
Abstract:A polymeric based hull protection system will be developed. The development will take three approaches. In the first approach, plates of Aluminum 5086 will be bonded to the hull in appropriate locations. In the second approach, polymeric energy absorbing layers will be applied to the hull in appropriate thickness to provide impact and abrasion resistance to the hull. In the third approach, a composite material based on an aramid fiber reinforcement will be used to build up areas on the hull that need impact and abrasion resistance. The proposed approach has been used commercially to prevent corrosion, impact damage and wear in structures that see high use in harsh environments. The polymeric system on which the proposed approach is based is low cost, tough, and easy to process. The polymeric system shows environmental stability and durability in maritime environments. The polymeric based protection system is very lightweight and does not require a significant amount of volume to provide significant improvements in impact and abrasion resistance. The proposed protection system can be contractor supplied or the Navy can perform the efforts to install the system; the processing is relatively simple.

Title:Heaters for Electron Guns
Abstract:The need for wire that is able to be heated up to high temperatures span a very large and diverse number applications and fields of use from everday consumer applications to advanced military and industrial applications. Some of these applications require heater wire that operate at very high temperatures. There are still a number of military and defense systems that use vacuum tubes/electronics. For example, some of the typical vacuum electronic devices (VEDs) that produce the electron beams. The Navy is using rhenium- tungsten (abbreviated Re-W or W-Re) heater wire in existing vacuum tube technologies to heat the cathodes of the electron guns. Domestic manufacturing sources for this type of heater wire are decreasing causing a continual increase in the costs to both government and industry to manufacture and purchase the wire. Various factors combine to create the diminishing manufacturing base. To address this need for a replacement heater wire/heater assembly for this Navy SBIR program, we propose two approaches for replacing the traditional and conventional method of W-Re heater wire fabrication. These two innovative approaches provide highly efficient precise, cost-effective heater solutions for cathodes for VEDs provide equivalent or enhanced performance at lower cost and are amenable to automated manufacturing.

Title:Alternative Manufacturing Meethod for Heaters for Electron Guns by Ink-jet Printing
Abstract:We will develop and demonstrate the key elements in a novel alternative method of fabrication of the heaters for dispenser types cathodes. The current methods depend on a wire that may soon not be manufactured anymore. The proposed method, radically alters the manufacturing approach introducing a complete data driven technology that will produce consistent heater elements in a wide range of configuration and will allow quick turnaround for design changes. The technology developed in Phase I will allow the heater designers to go beyond the limitations of current methods in terms of shape and distribution of the heater element within the heater. In Phase I, we will develop new formulation of solutions containing tungsten particles and an associated printhead that can ink-jet dispense the solutions into the desired pattern. The development also includes the process that will convert the printed particles into the conductive traces acting as heating elements. The feasibility of the fabricated heaters will be demonstrated following the stringent battery of tests that are part of the QC process of the current heaters.The long term opportunity is the implementation of the developed technology, materials, equipment and processes into production for a flexible design of low cost and high reliability heating elements.

Title:“Ship Shape”: Three-dimensional ship modeling for submarine combat systems
Abstract:The rapid identification of ships from periscope and other imagery is a capability important to a variety of submarine missions, including sea control, anti-surface warfare, battle group support, covert operations landings, and ISR (intelligence, surveillance, and reconnaissance) operations. When spotting a new vessel, the imagery taken from submarines can be useful to construct three-dimensional (3D) computer-aided design (CAD) models of ships that can be used for identification in future sightings, for computer- generated simulations, and for capabilities assessment. Currently the task of ship recognition from images requires substantial human involvement, and model building is labor-intensive. This research project seeks to demonstrate the feasibility of applying modern computer vision techniques to create a Ship Shape system that computes 3D CAD models from submarine periscope imagery of ships, with operator involvement limited to 15-30 minutes per model. We propose to leverage current computer vision techniques and demonstrate proof-of-concept algorithms for each phase of the computation, including image segmentation, sparse shape reconstruction, dense shape reconstruction, and CAD modeling with limited user interaction.

Title:Construction of Dense 3D Ship Models from Submarine Image Collections
Abstract:To create robust automated video analysis techniques for extracting, measuring, classifying, and identifying objects-of-interest, 3D object models have many benefits. Manual creation of a full range of 3D models would be a daunting task. A method for automatically generating 3D models from data gathered at sea would make populating a 3D model database practical as well as enabling updates to be generated as more information is gathered. Toyon Research Corporation proposes to implement a method for constructing a 3D model from a series of submarine-acquired 2D images. Toyon has developed industry-leading techniques for dense 3D reconstruction from moving sensor platforms. The effort will include development of methods for segmenting target ship data from marine backgrounds, automatically estimating the relationship among image viewpoints, compensating for target ship motion, and integrating results into a 3D model. A performance metric suitable for predicting automated target recognition performance will be created. The initial software implementation of the proposed algorithm will be used to assess the potential of the proposed reconstruction process and provide the basis for a recommended system design.

Title:Subsurface Expendable Profiler
Abstract:Areté and its subcontractor, Ultra Electronics Ocean Systems, will design the Subsurface Expendable Profiler. The Profiler merges Areté's Sensor technology and Ultra's acoustic communication technology to achieve untethered real-time data collection of conductivity, temperature, and depth. This device will be deployed identically to the historical probes using the submarine signal ejector. Once ejected and clear of the submarine, the device separates into two sections, one containing the CTD Sensor Module and another containing the Acoustic Communication Module. The CTD Sensor Module collects depth related temperature and conductivity data on its ascent and descent. This data is delivered via one wire tether to the Acoustic Communication Module, which in turn wirelessly sends the data back to the submarine in real-time. Upon completion of the measurement cycle the device scuttles. Direct depth knowledge allows versatility in the device to not rely on ascension to the water surface which supports under ice measurements.

Abstract:Progeny will design the Expendable Real Time Conductivity, Temperature and Depth Sensor (ExCTD) using our proven approach of incorporating Commercial Off the Shelf (COTS) sensors into a low cost expendable undersea buoyancy driven device. ExCTD will be launched from the submarine, notionally from the 3” launcher, ascend toward the surface while taking measurement and then change buoyance near the surface to descend while still providing real time data. Real time telemetry is provided to the submarine over a two wire communications driven by RS 485 communications architecture. A prototype will be built in Phase I based upon previous research and significant experience with deployable systems prototyping. The prototype will be in water tested to determine the effectives of the design and provide a basis for engineering changes for the Phase I Option where another prototype will be built and tested. The expendable nature of the device requires a low cost approach, and as such a detailed Bill of Materials will be developed, part costs will be estimated and the higher cost parts will have cost reduction approaches applied. Progeny is uniquely qualified to perform this research based upon previous design and experience with all aspects of the ExCTD.

Title:Crimpless Flexhose for Life-of-Ship Service
Abstract:The need to isolate mechanical shock and vibrations between shipboard machinery and the ship hull requires the use of flexible hose assemblies (FHAs) and resilient mounting structures. Resilient mounting structures and FHAs, in particular, are ubiquitous on all U.S. Navy ships, serving as a leak-free conduit for fluids and gases between interconnected pieces of shipboard equipment. Typical shipboard FHAs consist of reinforced polymer hoses that utilize various combinations of polymer tubing; fabric and metal braiding; separation layers; and protective outer coverings. Unlike rigid metal conduit, which can typically withstand harsh service requirements for the life of the ship, polymer-based FHAs degrade over time and need to be replaced often. Creare plans to develop an FHA that is affordable (based on a total life cycle cost basis), durable, and can withstand extreme shipboard service environments for the life of the ship. In Phase I, we will complete a proof-of-concept demonstration of our system. In Phase II, we will fabricate and test a full-scale prototype system.

Abstract:To develop concepts for affordable flexhoses that meet the Navy military specification requirements for MIL-H-24135B and that last the average life of a ship (40 years), Phase I will (a) apply a "useful lifetime estimation" experimental method to characterize existing MIL- H-24135B hose compounds; (b) design candidate new compounds formulated to be cost- comparable and performance-improved relative to current compounds; (c) validate cost/performance of new compounds via testing of key properties, e.g, compression set, abrasion, and UV/sunlight weatherability. The "useful lifetime estimation" method has been previously successfully applied to EPDM and nitrile rubber (NBR) motor mounts. The candidate new compounds are based on recent publications presenting advances in blends of EPDM and nitrile, as well as blends of NBR and HNBR (hydrogenated nitrile rubber).

Title:Ocean Sensor Interface Simulation for Integration Testing
Abstract:ASSETT, Inc. proposes to develop an acoustic modeling and simulation system that will enable thorough and comprehensive testing of Navy sonar systems prior to their integration with fielded acoustic sensors and arrays. Traditionally, the complexities of accurately simulating the detail characteristics and nuances of acoustic sensors and the ocean environment have precluded providing detail stimulation for testing new sonar systems. The objective of this project is to introduce a capability that enables thorough sonar system testing prior to integration with the acoustic array. The ASSETT approach leverages existing simulation and acoustic data management system to produce a low risk system design approach. The system will produce high fidelity, realistic time series data simulating the performance of specific acoustic array types with the ability to mimic the effects of a wide range of anomalous array performance. This time series data can in turn be used to stimulate the sonar processing system in the development environment allowing the evaluation of how the system responds to both nominal array performance as well as anomalous behavior. In addition, the system will have the capability to receive information the acoustic arrays and perform testing and performance analysis of the array performance.

Title:Ocean Sensor Interface Simulation for Integration Testing
Abstract:Sedna Digital Solutions, LLC (Sedna) has experience in the real world behavior of sensor technology as used in current NAVY combat systems. Sedna proposes to use its knowledge of real world sensor behavior, combat system array interfaces, existing high fidelity simulation, and general combat system test techniques to advance a concept that better matches what a combat system will encounter upon deployment with new or modified sensor arrays. Sedna proposes to optionally move the high fidelity injection point from post array signal conditioning to the array interface point. By making this move and adding real world sensor faults, the combat system will be stressed with real world like stimuli at the system development site. Stimulation at the system development site allows for cost effective repair of undesirable combat system behavior that would eventually have occurred at the installation site or, even worse, at deployment. Furthermore, Sedna proposes the reuse of existing high fidelity and array interface test software. The approach protects and enhances the NAVY’s previous investment in this software.

Title:Multi-Static Processing Using Sonobuoys as Opportunistic Receivers
Abstract:Existing organic sensors of surface combatants may be enhanced through the use of off- board sonobuoy receiver fields to extend both range and accuracy. Leveraging active transmissions in bistatic and multistatic geometries is a force multiplier that can provide additional courses of action for the war fighter. Coordinated active engagement with surface ship sources and many receivers, combined with existing monostatic active returns, may improve signal-to-noise ratio performance resulting in increased: probability of detection, detection range, submarine holding time, and ultimate success in submarine prosecution. This has become progressively more important with the proliferation of diesel electric and other quiet threat submarines that present greater challenges to today’s Navy. A successful solution must incorporate a capability to locate, with reasonable accuracy, all potential sonobuoy receivers to appropriately synchronize the timing basis. Additional acoustic processing functionality required for bi-static processing will be identified, leveraging existing Pulse Active Sonar Functional Segment (PASFS) capability. Modeling and simulation can be employed, leveraging existing air ASW mission planning tools, to provide evaluations of overall system performance across a variety of environmental and tactical scenarios.

Title:Multi-Static Processing Using Sonobuoys as Opportunistic Receivers
Abstract:Signal Systems Corporation proposes to use our Coherent Multi-static Acoustic Processing (CMAP) software to process the received acoustic sonobuoy data. The CMAP algorithms and software are an advanced coherent signal processing chain that is the baseline for the P-3/P-8A Multi-static Active Coherent (MAC) program and was developed under the Office of Naval Research’s (ONR) Littoral ASW Multi-static Program (LAMP). SSC will use our Multi-Static Performance Model (MSPM) simulation tool to show the improvement in detection range, time to detect, duration of track and other key metrics. Additionally, SSC has a Likelihood Ratio Tracker (LRT), which is an automated Bayesian multi-static detection and tracking fusion engine. This Bayesian processor will process the multi-static’s processors contact reports and fuse common contacts across different sonobuoys. The LRT processing is a proven method to dramatically improve the detection and false alarm characteristics of multistatic contacts and overcome the bearing ambiguity of using omnidirectional sonobuoy sensors by using the localization effect of a distributed field of omnidirectional sensors.

Title:New Radar/EW Transmit/Receiver Modules and Assemblies Technologies
Abstract:This proposal addresses an opportunity for the Navy to establish an integrated business and technical strategy to provide an Open Systems active array technology for emerging Naval radar and EW systems, and for modernization/sustainment of existing systems at lower cost. Transmit/ Receive (T/R) modules typically comprise 50 to 70% of the array acquisition costs which itself represents 60 to 80% of a radar system cost. The cost reduction benefits of applying an Open approach for these distributed units are substantial. Our prior work indicates T/R Unit production costs will be reduced on the order of 50% while active array operation and maintenance costs, which are ultimately even more significant, can be reduced by greater than 50%. MMCC, together with Saab Sensis, will develop GaN power amplifier open T/R unit designs tailored for USN radar and EW systems such as AMDR. The proposed design employs cost-effective commercially sourced multi-layer circuit board populated with open foundry and commercially supplied MMICs, assembled using industry standard processes. The overall objective is to realize designs having affordable Life Cycle Costs—3 to 5 times less than that of traditional approaches.

Title:Ultra-fast Broadband Low-cost T/R Switches based on Vanadium Dioxide Metal-insulator Transition Materials
Abstract:Over the course of this small business innovative research (SBIR) phase 1 (Ph1) program Metamagnetics proposes the development of next generation ultra-fast and broadband T/R switches with high isolation (>30 dB) based on thin films of vanadium dioxide (VO2) metal- insulator transition (MIT) materials produced via pulsed laser deposition method. The crystalline uniformity of these films will be strictly monitored via controlled deposition parameters including oxygen pressure, substrate distance from target, and laser power. This will ensure the best quality oxide films as in the fabrication of T/R switches crystalline uniformity as well as the design of the R/F microwave switch have both been shown to be crucial elements of the switching speed and isolation bandwidth performance. In fact, sub pico-second responses have been theorized for VO2 based T/R switches when more efficient RF microwave designs are utilized which is a marked improvement over existing MEMs and GaN T/R switch technologies. Other advantages of switches based on VO2 MIT materials include low fabrication costs, low insertion losses, and high isolation over broad bandwidths of operation. Together, these attribute make the development of VO2 switches based on MIT materials a very attractive solution for next generation T/R switch applications.

Title:Low Noise Torpedo Power Supply
Abstract:The MK48 Heavyweight Torpedo broadband sonar system performance is limited by the current power supplies used to power to the electronics in the torpedo. The broadband sonar system cannot operate to its full potential due to noise and ripple from these power supplies. Progeny Systems will leverage our extensive experience gained from our development and manufacture of low-noise power supplies, such as the Progeny designed Power Regulator Module (PRM) used in the MK54 Lightweight Torpedo, to develop concepts and solution for the MK48 Low-noise power supply. During Phase I, Progeny Systems will demonstrate the feasibility of our concept and approach by establishing performance goals based on the Navy requirements that will be verified by testing and analytical modeling. The re-designed power supply will have an input voltage of 275 VDC and will perform a DC to DC conversion to generate low output voltages from 3.3 VDC to 28 VDC with an output noise less than 0.15mVrms/rtHz and will be capable of providing an output power of approximately 1275 watts. The power supply shall reside in a volume of 225 cubic inches and weigh less than 13 lbs.

Title:Low Noise Torpedo Power Supply
Abstract:QorTek and Lockheed Martin Mission Systems and Sensors (LM MS2) are together proposing a new advanced integrated topology converter architecture that would significantly improve both low frequency rejection, the high frequency switching noise content and still fit within the confines of the design envelope. As the prime contractor for the MK48 CBASS torpedo, MS2 is uniquely positioned to work with QorTek in both assuring that the developed units meet performance requirements and providing the technology transition path directly to production line of the MK48. Low frequency noise that is not rejected by the power supply will couple to the sonar system hardware and will reduce the high performance extended bandwidth of the CBASS (Common Broadband Acoustic Sonar System) transmit and receive functions. The approach is to develop a modular solution in line with Navy torpedo performance upgrade programs to counter continuously evolving threats upgrades of the Mk-48. The central aim will be to design this new, very low noise power supply solution that will enable full wide bandwidth utilization of the MK48 torpedo through its novel noise reducing injection signal circuitry, such that at every stage within the power supply noise reduction, rejection, emissions will be addressed.

Title:Submarine Radar Vulnerability Reduction
Abstract:Submarine masts include optical sensors that provide the crew hemispherical viewing capability at the surface. There may be multiple optical sensors distributed circumferentially around the mast. These masts can include treatments to reduce their radar cross section (RCS). The optical windows for the sensors introduce facets and other reflecting features to the cylindrical masts which in turn cause significant spikes in the RCS of the mast when viewed from angles near normal to the each of the windows. We propose a novel method to reduce the RCS spikes caused by the optical sensors using existing absorbers treatments and common materials without requiring layered coatings to the optics aperture itself. The treatment concept holds strong promise that it will not degrade the performance of the optics unacceptably. Once proven for submarine optical apertures, this treatment can be adapted to electro-optic apertures on other platforms such as aircraft, ships and ground vehicles.

Title:Improved Anti-Corrosion Coatings for Undersea Cable Connectors
Abstract:The purpose of this project is to demonstrate the effectiveness of using Acree Technologies’ Energetic Deposition Processes (EDP) for the development of advanced nonconductive anti-corrosion coatings for undersea cable connectors. EDP has the advantage that it produces high density, porosity free, uniform coatings on complex shaped objects, including the insides of tubes and is capable of coating large structures on a commercial basis. In addition, the coatings that will be demonstrated in this project have a proven track record for corrosion protection. EDP deposited nonconductive coatings will significantly improve the life of outboard cable connectors, which will translate into a decrease in the frequency of dry- docking submarines thus resulting in significant cost savings to the Navy.

Title:Nanocomposite Coating for Corrosion Prevention of Underwater Connectors
Abstract:Navy Submarines utilize a large number of undersea electrical connections to systems located outside the pressure hull (sonar, radar, communications masts etc). Long service life of undersea connectors is critical since maintainance and replacement is difficult and costly. Protection of undersea connectors from corrosion is a challenge. Current anti- corrosion technologies cannot easily be applied to complex connector geometries and are subject to a very specific form of corrosion called cathodic delamination. A fundamentally new type of anti-corrosion coating has been devised to address the problem. The proposed coating utilizes the characteristic of self-assembly, to achieve extremely even coatings on complex geometries. The coating is applicable to multiple surface types with good adhesion and is highly resistant to water and ionic permeation. Initial cost projections for the coating are favorable, with the potential for convenient and environmentally friendly manufacture using standard immersion baths. The Phase I study will establish concept feasibility, demonstrating key performance criteria using coated test coupons.

Title:Improved Anti-Corrosion Coatings for Undersea Cable Connectors
Abstract:Texas Research Institute – Austin (TRI/Austin) first developed non-conductive coatings (NCC) for marine connector applications in the mid 1990’s. These coatings are applied by a plasma spray process, and the patented technology has reduced the cost of ownership for the U.S. Navy by reducing down time of submarines for replacement of failed connectors from cathodic or corrosion related mechanisms. In spite of the outstanding performance of the original Bond-Coat system, the application is limited to flat or cylindrical surface geometries due to the need for uniform coating thickness. Numerous nonsymmetrical outboard connector types are currently used in Navy Submarines that cannot be coated using the current technology. TRI/Austin Inc. proposes the development of a second generation NCC for marine connectors that will permit application to complex surface geometries. The technology developed by this SBIR will be capable of coating, with uniform thickness, surfaces with 90 degree angles. The process will also enable coating of connector inside diameters. TRI/Austin will be teaming with a major underwater connector manufacturer to develop materials that can be processed using conventional application equipment and procedures.

Title:Durable Hydrophobic Barrier Coating for the Remote Minehunting Tow Cable
Abstract:The tow cable strands used to tow the AQS-20A from the RMMV are made from Nitronic 50, an austenitic stainless steel that, under normal circumstances, exhibits excellent corrosion resistance and strength over a wide temperature range. Unfortunately, the cables are experiencing early life corrosion problems due to salt water deposit buildup that occurs over repeated operations and subsequent system stowage. Because of the difficulty and logistics associated with retrieving and storing the RMS on the LCS platform, freshwater rinsing and other cleaning methods are unacceptable. Therefore, Luna Innovations and its team will apply a sol-gel derived, mechanically-durable and optically-transparent, hydrophobic coating that has excellent watershedding properties and that is easily applied to RMS tow cables in a thin and low-cost package. The primary function of the coating will be to shed salt water through its inherent hydrophobic nature as the RMS is retrieved from the sea. This capability will drastically reduce the propensity of salt accumulation on the stainless steel tow cable assembly. In addition, Luna will include corrosion inhibiting compounds and/or pigments to provide a secondary line of defense against corrosion processes.

Title:HybridSil Anticorrosion Coatings for RMS Tow Cables
Abstract:The objective of this Phase I SBIR program is to develop and qualify a next-generation HybridSil® anticorrosion coating that provides robust, long-term corrosion protection to the Remote Minehunting System (RMS) tow cable within demanding marine environments. The proposed HybridSil® anticorrosion coatings will be molecularly engineered specifically for Nitronic 50 and unlike current state-of-the-art anticorrosion coatings, have the capability of withstanding extreme flexing, abrasion, and seawater flow operations. Importantly, the proposed template inorganic copolymer has undergone extensive corrosion qualification (ASTM G44, GM 9540P, ASTM B117, ASTM G67, ASTM G66), demonstrated self- cleaning characteristics within actual marine environments, revealed exceptional UV durability (ASTM G154 and G155), and is currently undergoing sea trials on a combat active U.S. Navy vessel within the Atlantic fleet. Building from this extensive technical foundation, NanoSonic will augment its HybridSil® anticorrosion technology for protecting Nitronic 50 stainless steel cables from harsh corrosive and abrasive damage within simulated RMS environments. A statistical design of experiments including rigorous corrosion, abrasion, mechanical, and environmental testing will be employed to down-select Phase I optimized systems. Transition success is ensured through multiple Phase III transition partners and an established pilot scale HybridSil® manufacturing infrastructure.

Title:Generation of EW Libraries and Automatic Threat Identification (GELATI)
Abstract:Electronic warfare (EW) systems classify emitters by matching the signals detected against reference signatures in a tactical EW library. Since emitter signals can differ markedly from their library signatures (due to drift, new modes, propagation effects, etc.), ships with AN/SLQ-32(V) or SEWIP Block 1/2 systems use a labor-intensive process to iteratively “tailor” or “color” reference signatures to more closely resemble the signals they expect to detect. To enable ships to automatically build and update their tactical EW libraries—while improving their ability to respond to new threat emitters—we propose to develop a system for Generation of EW Libraries and Automatic Threat Identification (GELATI). GELATI will perform the following: (1) generate data sets containing representative signal parameters by thoroughly exploring the envelope of tactical and EW scenarios; (2) account for signal attenuation and distortion by noise and propagation effects; (3) compute recommended revisions to the reference signatures in the tactical EW library to optimize emitter classification performance; and (4) rapidly classify threat emitters even if their reference signatures are not yet updated. By leveraging existing and developing technologies, we will demonstrate GELATI’s conceptual and engineering feasibility in Phase I, while ensuring that GELATI successfully interfaces with current and future transition targets.

Title:Automated Generation of Electronic Warfare Libraries
Abstract:Metrological differences between tactical sensors result in a wide range of accuracy, completeness, and correctness of features used for object classification. Thus, it is typical practice for Subject Matter Experts (SMEs) to develop the required reference libraries so that they are tailored to each tactical sensor type and, in some cases, sensing environments. The process of developing this tailored library is often called “coloring” the reference library. The SMEs objective is to optimize the classification performance (w.r.t. some metric(s)) using a feature-based classifier.The proposed Hierarchical Emitter Library Optimization (HELO) technology mimics the coloring process in order to generate an Emitter Library that optimizes the classifier performance while avoiding the need for a labor-intensive manual process that requires SME knowledge. HELO employs a general Hierarchical Evolutionary Programming (H-EP) based upon the Genetic Programming (GP) optimization paradigm to achieve this optimization. This approach provides a computationally scalable process that rigorously quantifies the performance of the classification algorithms without knowledge of its algorithms. Using the performance assessment of the classifier, a large set of potential emitter libraries (population) is iteratively refined (evolved) until an optimal (or sufficiently good) emitter library is generated. The solution is hierarchical because the evolution of the population is achieved jointly in two stages: (1) evolution of the coloring functions to generate a parameter library for a particular parameter type and (2) evolution of the set of parameters used by the classifier.

Abstract:This SBIR develops technologies to automate the creation of Electronic Warfare (EW) emitter libraries to correctly identify threat (and other) signals of interest.In this effort RAS will show how to automate the use of the national databases to extract data and manipulate it into a form suitable for automating the generation of Mission Data or Emitter ID tables needed in operational EW systems to quickly identify the threat. Important to this are algorithms to determine ambiguities and then eliminate them based on additional criteria from ELINT data bases and other available data bases such as Orders of battle, Operational ELINT and SEI databases.The approach leverages RAS extensive expertise gained from EWIR / KILTING and CED database development, analysis and applications and our development of several generations of emitter parameter measurement algorithms to extract conventional pulse parameters (RF, PW, PRI), RF and PRF agility parameters, intentional modulations on pulse and scan patterns.Approaches are assessed and selected for PHASE II software development and demonstration within the SEWIP Block II architecture. During and after Phase II, RAS will work with SEWIP Block II prime Lockheed Martin and the government to define, install and demonstrate the technology on a suitable test-bed.

Title:Innovative Algorithms for the Categorization of Mine-Like Objects Using Standard Sonar Return Data.
Abstract:Mine countermeasures will be a critical mission of the Littoral Combat Ship. This capability will be fulfilled by existing and future advanced SONAR systems to detect surface and volume mines. The performance of these systems is degraded by the large numbers of false alarms due to surface, volume, and sea bottom clutter, which increase operator workload and reduce effective search rate. Areté Associates proposes to develop an integrated false alarm mitigation strategy to improve the detection performance of existing military and COTS SONAR systems. Our approach builds upon over 30 years exploiting powerful data analytic tools and techniques for detection of weak targets in highly cluttered environments. Areté's in-house automated tools will be used to identify optimally discriminating spatial and spectral feature sets and feature-based classifiers to improve the performance of individual sensors. Additionally, Areté-developed weak-target tracking techniques will be used to combine temporal data from multiple scans, or multiple sensors, to improve weak target detection and eliminate short-lived false alarms. The optimal combination of spatial, spectral and temporal information will provide a powerful and robust object classification algorithm that will probability of detection and reduce false alarms in SONAR MCM applications.

We will adapt the current torpedo-based MIRK algorithms to MCM sonars to reduce falseclassifications and other performance degrading issues. Phase I will examineand characterize the physics of the problem using mathematical modeling andrecent successful testing with recorded sonar data against real targets. InPhase II we will insert the algorithms in an MCM sonar and demonstratesignificant reduction in false classifications and other performance degradingissues as well as real time target classification.

Title:Shipboard Software Deployment Tools for Complex Heterogeneous Systems
Abstract:Navy tactical software, such as the AN/SQQ89A (V)15 surface ASW environment, requires hundreds of interacting software components deployed across a heterogeneous set of compute platforms and communication devices. Navy sonar operators tasked to perform maintenance often do not have the technical expertise with multiple operating systems and hardware devices deployed on the platform. Detailed Software Version Description (SVD) documents are necessary to ensure that an operator with limited expertise can perform the complex job of reinstallation and maintenance. This proposal seeks to design a software installation and maintenance toolkit that greatly reduces the effort, knowledge, and time required for these activities. The toolkit will automate nearly every activity required for system installation and maintenance. Of particular node is removing the requirement that shipboard personal be required to edit configuration files and input data on a command line as both of these activities are error prone and can be confusing.A significant part of the tool design will be aimed at the system integrator to enable efficient packaging of the deployed systems and for deployment testing prior to package dissemination.

Title:Shipboard Software Deployment Tools for Complex Heterogeneous Systems
Abstract:Naval Combat Systems have evolved into complex systems, based on networked collections of heterogeneous software from different vendors. As a result of these efforts, combat systems have become a pinnacle of complexity in terms of software deployment activities. This issue is exacerbated when ships force personnel who are charged with the operation and maintenance of these systems do not possess the same levels of expertise and skill that the software vendors utilize when delivering software to a platform. When these factors are combined together in a casualty or outage situation onboard a vessel, it results in a real loss in ship capability and operational readiness.The solution that Progeny Systems will deploy to address these software deployment challenges will integrate our existing strategies and strengths in the end-user minimal concept, paired with an innovative software framework that provides tools and libraries to streamline the software deployment process. The software framework will be packaged into a standard hardware product for delivery, drawing on a couple of feasible, innovative strategies for software deployment. The system will be designed with an open architecture both in hardware and software, which provisions the solution to be extensible and scalable to other technologies, platforms and projects.

Title:Aerostat Communications Relay from Unmanned Surface Vehicle
Abstract:The CommLift Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicle (UAV) is an alternate and novel approach to providing long range, over-the-horizon, communications for surface vessels; it uses a tethered electric UAV to carry a radio payload to suitable altitude, rather than an aerostat. The tether provides power from an unmanned surface vessel (USV) to the UAV and also bi-directional communications between them. Since electric power is supplied from the surface, the UAV endurance is unlimited. The essential innovations are (1) an autonomous UAV to be tethered to takeoff, follow above, and land on, a USV, (2) to provide UAV power and communications over the tether, and (3) paired UAV autopilots (one at the surface and one on the UAV) to allow the UAV to follow USV movements and to control UAV takeoff and landing. The Phase I performance metrics are demonstration of suitable power and communications over a >525 ft. tether, tethered takeoff and landing of a multirotor UAV from a 30 knot moving vehicle and control of a high voltage brushless DC motor’s speed and design of tether control system and surface based support package.

Abstract:Robotic Research LLC in an exclusive partnership with Carolina Unmanned Systems (CUV) and Unmanned Systems International Corporation (UnSysCorp), is developing the Modular Aerostat Communications Relay system (MACRel). MACRel is a system for deployment and recovery of a Lightweight Aerostat System (LAS) to an unmanned surface vehicle (USV). The work will include a sensor study that allows for a low cost method for the MACRel system to identify and react quickly to changing environment conditions that influence the launch, stable flight and recovery of the LAS. Using sensor inputs, iMACRel makes it possible to predict when to deploy or retract tether in order to decrease strain on the aerostat and the tether itself. The objective is to increase the communications range between the Littoral Combat Ship (LCS) seaframes and Mission Package Unmanned Surface Vehicles (USVs) by developing a modular aerostat communications relay system for the radio that is semi-autonomously deployed and retrieved from the LCS Unmanned Influence Sweep System USV.

Title:Affordable Point of Use Conversion (PUC) Module for 400Hz Power System Applications
Abstract:Currently 400 Hz power systems onboard US Naval ships use centralized and redundant frequency conversion, whereby 400 Hz power is generated in centralized locations and is then distributed to numerous loads located throughout the ship. This distribution system approach leads to the placement of large and expensive frequency converters onboard the ship and long cable runs. Additionally, the needed distribution equipment feeding all the 400 Hz loads is redundant to the 60 Hz distribution system. A more effective and survivable approach would utilize the existing 60 Hz distribution system to provide power to compact PUCs located directly at the load site. This would eliminate the need for separate 400 Hz distribution systems and eliminate the need for all the 400 Hz distribution equipment. In this Phase I SBIR, we propose to develop a 40 kW high power density, affordable PUC modules that have three times the power density and half the cost of the MFPMs used in the PNCC. We propose to develop these modules using SiC FETs and nano crystalline cores for the filter chokes. The successful development of this technology will improve the affordability and survivability of Naval ships.

Title:Low Cost, Ultra-Power Dense Point of Use Conversion System
Abstract:Naval ships currently operate independent 60 Hz and 400 Hz power systems, resulting in unnecessary redundancy and high ship costs. A better approach is to utilize existing 60 Hz equipment and place the 400 Hz equipment at the load site. However, limitations in current electronic power densities make components too large to be strategically located. Mainstream proposes a modular, low cost, ultra-power dense point of use conversion system that is scalable to various load levels and output types. The proposed solution will increase the power density of naval power electronics to levels required to be strategically located, lower cost by 30%, and increase reliability by 20% over current solutions. This high level of power density is achieved without the use of high temperature SiC semiconductors, which can significantly increase system cost. In Phase I, Mainstream will optimize the power electronic and thermal management system architecture, and develop the control system for both. In Phase II, Mainstream will demonstrate a full-scale prototype on a simulated naval power system. Mainstream’s proposed technology will not only improve the reliability and power density of military power supplies, but can also satisfy commercial power supply goals

Title:Semi-Autonomous, Reliable, Safe Recovery of the Remote Multi-Mission Vehicle (RMMV) in Various Sea States.
Abstract:To improve the at sea recovery of the Remote Multi-Mission Vehicle (RMMV), the Advanced Optical Systems (AOS) has teamed with Maritime Applied Physics Corporation (MAPC) to deliver a solution employing passive optical sensors capable of detecting 6DoF position with accuracies surpassing the human eye. The sensors are a key component of the proposed Autonomous Vehicle Recovery System (AVRS) that will provide rapid position and rate information and/or commands to ship control systems in response to motion between the RMMV and the capture spine. The AOS team’s solution will also provide control messages to the Twin Boom Extendable Crane (TBEC) and the Remote Operator Panel (ROP). The added controls will generate position and rate messages for use by the TBEC control system to simultaneously manipulate up to eleven tag-lines attached to the recovery capture spine and RMMV. Removing the inherent human latencies from the current system and implementing controls of the ROP improves recovery by decreasing the time needed to align the capture spine with the RMMV receiver. Recovery of the RMMV is safer for personnel and equipment, therefore ship missions are not delayed due to long recovery sea details.

Title:Multi-Disciplinary Approach to Increased Automation for RMMV Recovery Operations
Abstract:Shipboard launch and recovery of remotely operated vehicles (ROVs) is a challenging engineering problem requiring careful design and integration of hardware and software. The seaway-induced relative motion between the host vessel and ROV is often difficult to measure or model, which may render automatic control approaches ineffective and force reliance on manual operation by a very small number of highly trained operators. The success of a launch or recovery is thus highly dependent on the proficiency and alertness of the operator(s). Recovery of the RMMV from the LCS Independence variant is especially challenging and labor-intensive. The overall objective of the research is to provide increased recovery automation to enhance safety and repeatability while reducing operator workload. Barron Associates, Inc. and its research partners propose a tiered research and development program that assesses and quantifies the degree of recovery automation achievable with varying levels of cost. A simulation environment that includes vehicle, flow, and recovery system models will be developed. The team will follow a building-block approach that first maximizes the autonomy that is achievable within the basic confines of the existing infrastructure. Based on the simulation results, innovative modifications will be considered within given cost and technical risk guidelines.

Title:Semi-Autonomous, Reliable, Safe Recovery of the Remote Multi-Mission Vehicle (RMMV) in Various Sea States.
Abstract:This effort utilizes a new Launch and Recovery (L and R) System called Soft Rail. Soft Rail significantly eliminates the surface motion by deploying a unique depressor/drogue (D/d) system from two lines underwater below the surface interface conditions. These lines extend to the ship and are referred to as “Soft Rails” because they are tensioned by the D/d system. The D/d is inherently stable underwater and significantly reduces the surface motion in these lines. Thus payloads are stable as they traverse the Soft Rails on a trailer-like launch and recovery carriage. This operation is analogous to a gondola traversing a suspended cable. All this is done while the ship remains underway further reducing motion. Soft Rail has been successfully demonstrated at sea off the SEAL support ship the C Commando. Soft Rail can be used to L and R just about any payload including; surface RHIB’s, UAV, RMMV’s and perhaps even large UAV’s. Soft Rail may be the most significant advancement to at-sea L and R since the development of the Davit.

Abstract:Development of an ultra-compact, quantum cascade laser module delivering over 20 W in the mid-wave infrared and 20 W in the long-wave infrared spectral regions, with a beam quality parameter M2 of less than 2.0, is proposed. The module will have an operational capability of a variable repetition frequency in the 10 MHz to CW range with a microsecond time scale for switching between the two extremes. Collinearity between the mid-wave infrared and long- wave infrared beams will be better than 50 µrad and lateral displacement of less than 0.5 mm.

Title:Ultra-High Brightness Dual Band Mid-Wavelength Infrared and Long-Wavelength Infrared Semiconductor Laser Module Based on Wavelength Beam Combination f
Abstract:There is a compelling need for scaling the output of mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) lasers to much higher power, brightness, and energy. Applications of such sources include spectroscopic detection of the “fingerprint” of molecular absorptions and infrared countermeasure systems in response to increasingly sophisticated seeker technologies and increased threat ranges. Existing, commercially available direct diode or semiconductor lasers have some of the most desirable attributes: highest efficiency, greatest compactness (small size, weight, and power or SWaP), and wavelength selectability from the UV to the mid-IR bands. The main disadvantage is poor output beam quality. TeraDiode’s technology of Wavelength Beam Combination (WBC) effectively solves the poor output beam quality problem of direct diode lasers. We will build a dual-band MWIR and LWIR laser for this program based on WBC of high power quantum cascade lasers with an average/peak power of 10/20 W and high beam quality. TeraDiode’s technical approach is scalable to much higher power and brightness levels.

Title:Autonomous Classification of Acoustic Signals
Abstract:Actionable situational awareness in cluttered and littoral environments with a passive sensor network requires a cost effective system capable of a high probability of detection of low-level undersea sound sources in large shallow water areas. Distributed passive arrays and autonomous sensor platforms have the potential for persistent monitoring of surface and subsurface acoustic targets. However these sensor platforms generate a tremendous amount of data that would require a great deal of operator supervision and detailed understanding of target signatures. 3 Phoenix, Inc. (3 Phoenix) has teamed with the Integrity Applications Inc. (IAI) to develop a robust suite of detection, classification, and localization (DCL) algorithms that will improve automated target recognition (ATR) of surface and subsurface contacts in high clutter littoral environments. We propose novel feature extraction methods in tandem with an efficient nonlinear adaptive kernel elastic net (AKEN) classification. The proposed DCL engine will be optimized for situational awareness within an operating scenario consisting of cluttered littoral environments. Efficient methods of implementation will be derived to enable real-time algorithm operation on existing hardware/firmware platforms such as the Persistent Littoral Undersea Surveillance (PLUS) processor.

Title:Autonomous Classification of Acoustic Signals
Abstract:U. S. Navy tactical and strategic forces need a real-time, autonomous classification capability to realize the full potential of fixed acoustic surveillance sensors. In this work, we demonstrate the feasibility of integrating a novel, physics-based automatic classification algorithm into a new, large aperture Planar Array Prototype (PAP). The approach differs from traditional “intel-based” classification methods by using fundamental knowledge of normal mode propagation constraints to exploit natural differences in the way surfaced and submerged sources excite the shallow water waveguide. OASIS has successfully employed this approach in the past on both towed and fixed horizontal line arrays. The Phase I effort will determine the feasibility and identify any technical issues associated with applying the concept to the PAP arrays under consideration by PMS-485. Under the Phase I Option, the sizing and timing requirements associated with the implementation of the PAP classification algorithm on a commercial off-the-shelf (COTS) hardware platform will be analyzed. Finally, a plan will be written that details the steps for integration of the algorithm into the Shallow Water Surveillance System (SWSS) autonomous detection, classification, and tracking (DCT) baseline, which leverages the OASIS-led real-time DCT development and integration effort under the ONR Persistent Littoral Undersea Surveillance (PLUS) program.

Title:Mission Planning Application for Submarine Operations and Risk Management
Abstract:Sonalysts proposes to develop a Mission Planning-Evaluation Tool (MP-ET) to support submarine Commanding Officers’ risk and operational assessment of mission plans. Our approach is to extend the current APB-13 Mission Planning Application (MPA) by using a fuzzy logic approach. This method enables encoding the heuristics used by experts into an automated, quantifiable evaluation of operational risk. Our approach is to use a simulation engine to run multiple trials of a course of action-scenario combination, and evaluate the output with a fuzzy logic engine. Our fuzzy logic rule set will be developed by interviewing current and former submarine Commanding Officers and reviewing relevant submarine grounding, collision, mission, and exercise reports. We will leverage or develop, as necessary, modular interfaces to the existing Mission Planning Application (MPA). Simulation outputs will be processed through a Fuzzy Logic (FL) engine to compute risk and effectiveness for presentation to a decision maker. We will develop an initial Risk Assessment Display, aimed at presenting risk elements, risk factors, and an aggregated risk timeline which will present FL output to the Commanding Officer. We will also examine the run-time feasibility of using a simulation engine for real-time evaluation of risk and effectiveness.

Title:Mitigation of Biologically Induced Active Sonar Reverberation in Littoral Regions
Abstract:Historically, operation of the mid-frequency active sonar in littoral regions has presented sonar operators with challenges due to the complex nature of the ocean acoustic environment in shallow waters. Although there are complex reasons for the appearance of clutter, research has shown that biological backscatter currently produces serious interference in mid–frequency active sonar. This proposal will show that air bladders of small fish, which are found with great abundance in the ocean, have an acoustic resonant frequency that is within the current AN/SQS-53C echo-ranging band and cause serious performance degradation. It is proposed that the performance degradation resulting from fish swim bladders can be largely eliminated by exploiting the known resonant characteristics of biologics to transmit at frequencies away from that of the resonant biological backscattering. The objective of this proposal is to demonstrate the feasibility and efficacy of using a modified transmit spectrum (of currently unavailable bands) and an associated innovative in-situ analysis and selection method, to mitigate the resonant backscattering effects due to biologics on mid-frequency active sonar returns, in particular, the AN/SQS-53C.

Title:Mitigation of Biologically Induced Active Sonar Reverberation in Littoral Regions
Abstract:Applied Research in Acoustics LLC will formulate and develop new concepts and algorithms for data-driven clutter-adaptive waveform-synthesis and CFAR normalization processing based on physical models of resonant backscattering from heterogeneous aggregations of swim-bladder-bearing fish that will significantly improve active sonar detection capability in littoral waters by reducing the number of false contacts and decreasing the amount of display clutter. The new signal processing concepts and algorithms developed and evaluated in this work will comprise (1) clutter-adaptive waveform and matched-filter synthesis using a data- driven approach to mitigate reverberation and clutter due to resonant scattering from fish, (2) clutter-adaptive CFAR normalization of the within-beam time series using model-based and data-driven assessment of range-dependent amplitude statistics, and (3) clutter-adaptive cross-beam and image-based normalization using model-based and data-driven assessment of spatial statistics of clutter from fish. The performance and feasibility of these new concepts and algorithms will be evaluated individually and as an integrated processing system with simulated midfrequency active sonar data representative of the AN/SQS-53C operating in a shallow-water environment with various sources of biologically induced clutter, as generated by a validated sonar-simulation model and a validated analytical model of scattering from heterogeneous aggregations of swim-bladder-bearing fish.

Title:Mitigation of Biologically Induced Active Sonar Reverberation in Littoral Regions
Abstract:The proposed effort develops and evaluates features exploiting the swim bladder resonance observed in broadband echoes from fish for automatic screening, reducing mid-frequency active sonar clutter. Real world data from shallow water is used to develop and evaluate features for discriminating between the broad peaks characteristic of an aggregate echo from a school of fish and the comparatively flat echo from target and target-like scatterers. Exploitation of this feature is important because biologics can produce high level echoes, move, and are not amenable to other sensing modalities. Because the frequency and sharpness of the resonances depend strongly on the relative density of fish species and their depth, physically motivated features of the spectral shape and auto-regressive coefficients from speech recognition are leading candidates for investigation. Another product of the work is an understanding of the system bandwidth required to achieve reliable automatic screening of fish echoes without significantly reducing target detections. Beyond the benefits of reliable screening, the developed features themselves offer the potential to improve associations in automatic tracking. This project will demonstrate the feasibility of exploiting fish swim bladder resonances to improve automatic screening and tracking performance of U.S. Navy mid-frequency active sonar systems.

Title:Long-Range Maritime Atmospheric LIDAR
Abstract:ADA Technologies is teaming with the Colorado School of Mines, Raytheon and Q-Peak to propose the development of a novel Maritime Atmospheric LIDAR (MAC-LIDAR) capable of providing critical atmospheric characterization information to support the effective operation of next generation laser weapons. The proposed system is based on laser light scattering to measure attenuation of a laser beam traveling long distances in the atmosphere and mostly bounded by seas or oceans. The system concept is similar to conventional LIDAR, but greatly simplified to make it compact and practical for use on war ships. The mast mounted system will illuminate the atmosphere surrounding a ship and produce 3-D images of atmospheric attenuation surrounding the ship. MAC-LIDAR constructs 3-D images of attenuation by combining data from time gated 2-D images of laser light scattered back to system with polarization filtering. Beam attenuation will be computed using a single wavelength laser source at 1064 nm. The Phase I activities will provide a proof-of-concept instrument as well as preliminary evaluation data in a laboratory environment in the Base period (range of up to 105 ft) and in a longer underground tunnel in the Option period (range up to 800 ft).

Title:Compact LIDAR for Continuous Monitoring of Atmospheric Extinction
Abstract:Operation of a ship-borne Laser Weapons System (LWS) requires new capability to dynamically characterize the maritime atmosphere to predict laser effectiveness. Atmospheric attenuation data for ranges to the horizon will be needed to support weapons selection against surface or airborne targets. Systems that can characterize the atmosphere continuously and that also can operate on-demand, will provide the greatest flexibility. Physical Sciences Inc., with its subsidiary Q-Peak Inc., proposes to develop an advanced, highly compact Lidar (Light Detection and Ranging) sensor capable of continuous, automated mapping of atmospheric extinction. The lidar will operate at a wavelength of 1.0 micron at a transmit power consistent with eye safety. It will operate autonomously and continuously. The Phase I program will consist of analysis and conceptual designs of the lidar sensor. The Phase I Program Option will consist of additional engineering design to integrate the sensor into the designated demonstration platform, as well as a demonstration of the laser transmitter. The Phase II Program will develop and test a field-worthy prototype sensor package. The Phase III Program will integrate and test the package on a designated Navy platform.

Title:Maritime Dynamic Atmospheric Characterization for Naval Laser Weapons System
Abstract:Science Research Laboratory, Inc. (SRL) will develop a prototype Extinction Imager (EI) suitable for shipboard installation based on the research of Janet Shields (Scripps, UCSD). The Shields EI uses radiance contrast measurements of the sky/ocean interface at the horizon to determine the aerosol extinction coefficient along a horizontal path. This measurement is combined with models of atmospheric extinction as a function of altitude and vertical backscatter measurements from a ceilometer to predict extinction along arbitrary slant paths. In Phase I SRL will test an EI prototype on nominal 5 km east coast ocean ranges (1) under daylight and starlight conditions, (2) in the visible and 1000 nm wavelength bands and (3) with both black light trap targets and clear horizon measurements. These measurements will be used to design a Phase II EI camera system capable of 24/7 extinction predictions. SRL will also test MEMS Inertial Measurement Units to develop a design for an image-stabilized EI system that will scan the horizon while correcting for low-frequency pitch and roll. In Phase II the SRL EI system will be tested with a COTS ceilometer and an aethalometer to measure both aerosol and atmospheric scattering and absorption.

Title:Improved Detection, Localization, and Classification of Torpedoes
Abstract:Torpedoes are a lethal threat to surface ships, and the ability to detect them remains a ship- safety priority. Current torpedo-detection algorithms are effective against certain models, but evolving torpedo propulsion systems and enemy tactics constantly chip at away at the present defense capability. This proposal will demonstrate opportunities to use the hull-mounted sensor to significantly close that gap by increasing the probability of detecting torpedoes and reducing false torpedo alerts. Work will be focused on developing improvements across three areas of the torpedo-detection chain: beamforming, detection, and classification.1. Utilize extended bandwidth and other improvements to the hull-array adaptive beamformer (ABF) to better detect both kinematic and acoustic-signature torpedo characteristics2. Develop a kinematic feature-detector algorithm capable of detecting various torpedo motion patterns (for example, wake-homing torpedoes) with the hull array3. Develop a classifier that incorporates data from the hull kinematic and acoustic-feature detectors, as well as any other available sensors, to determine whether a contact has weapon-like characteristics Other benefits include reduced development time and costs by reducing the need to retune the torpedo classifier when threat torpedo characteristics change.

Title:Improved Detection, Localization, and Classification of Torpedoes
Abstract:By exploiting the high Doppler rate of torpedoes, low-latency, high-reliability, and high- mobility torpedo detection, classification and localization (DLC) can be accomplished with joint active-passive sonar signal processing using the hull array. Our system combines passive cues and a new active signal processing technology for deployed waveforms. The signal processing is carried out in real time within a common time-frequency representation for active-passive torpedo DLC but uses a novel technique, invented by chaotic.com, called Doppler-filtered pulse compression (DFPC). DFPC provides high probabilities of detection and correct classification while virtually eliminating confusable clutter. DFPC also provides the high Doppler and range resolution needed to spatially resolve salvos more efficiently than traditional high-resolution waveforms. To make reliable performance predictions for torpedo DLC, a method for extracting, validating, and generalizing highly realistic channel and target impulse response functions from legacy data is proposed.

Title:Shiphandling Educator Assistant for Managing Assessments in Training Environments (SEAMATE)
Abstract:Virtual Environments (VEs) provide a cost-effective alternative to train students to perform tasks that would otherwise put lives and platforms at risk. However, current VE training methods still require highly trained instructors to closely monitor student progress, effectively intervene when students’ actions risk imparting negative learning, and provide detailed assessments of student skills. The demand for VE-based mariner training has been growing for over a decade and currently exceeds the number of available instructors, limiting the potential of this method. To more efficiently meet training demands and enhance the effectiveness of VE-based training, we propose to design and demonstrate a Shiphandling Educator Assistant for Managing Assessments in Training Environments (SEAMATE). SEAMATE will enable a smaller number of expert instructors to effectively work with larger groups of students through a combination of improved performance tracking, automated feedback, and efficient alerting methods. The SEAMATE instructor support system will include a tablet-based interface that supports at-a-glance awareness of individual student status to effectively direct the instructor’s attention. SEAMATE will also provide dynamic feedback and reporting to assist instructors’ awareness of student progress. As such, the system will increase the effectiveness and efficiency of VE-based training methods, while reducing demands for highly trained instructors.

Abstract:The United States Navy currently uses klystron-based and high power modulator tube Radar Transmitters that are increasingly more expensive to own and operate. Daico proposes to ultimately replace specific tube-based Transmitters with fully Solid-State Transmitters (SSTx). The proposed feasibility study will demonstrate significantly higher standards for Availability (Ai), Reliability and Maintainability while reducing Total Cost of Ownership by adapting, to a shipboard environment, our proven, scalable transmitter architecture, called (m+n) Automatic Redundancy Technology Transmitter, (m+n) in short, for coherent transmitters. The (m+n) main building block is an innovative High Power Amplifier design that supports true hot-swapping, automatic failover and graceful power degradation. The first (m+n), invented in 2008 and deployed in a mission critical ASR-3 application in 2010, delivers >99.99% Ai. (m + n) has been commissioned for more than two years without any operating failures to date. The proposed feasibility study will confirm (m+n) is adaptable to shipboard environments, utilizing state of the art solid state technology, with capability >500kW peak output power in frequencies through C-Band. This proposal will demonstrate the feasibility of our innovative High Power Amplifier in various existing Radar Systems, like SPS-49, SPN-43, SPY-1B (Pre-driver), AeroStat and so forth.

Title:High Power Solid State Amplifiers
Abstract:Diversified Technologies, Inc. (DTI) proposes to design and build an advanced, pulsed solid-state transmitter capable of replacing legacy klystron amplifiers in Navy radars. The new transmitter will integrate commercially available semiconductors into a novel DTI combiner architecture, and will deliver higher availability, simplified maintenance, and an overall reduction of operating costs in comparison to existing klystron systems. This particular architecture is well-suited for applications from UHF to S-band and beyond. Pulsed versions of this system are scalable to a megawatt power level for high duty factor coherent radars. An L-band version of the transmitter will be discussed in this proposal.

Title:High-Power Solid-State Amplifier
Abstract:To address the Navy need for a high peak- and average-power solid-state amplifier to replace existing Klystron tube amplifiers in surface Navy radar, Physical Optics Corporation (POC) proposes to develop a new amplifier by Spatially Combining in a Radial configuration many Amplifier Modules (SCRAM). It is based on spatial combining of an array of over 350 power amplifier modules of 1 kW output to produce 350 kW of peak RF power at 5% duty cycle. The amplifier uses the new generation of rugged 50 Volt laterally diffused metal oxide semiconductors, and can tolerate high voltage standing wave ratios. This will allow hot swapping of the individual amplifier and power supply units, a Navy requirement. This new amplifier will significantly increase the critical path mean time between failures compared to present Klystron-based amplifiers. The innovation in this solid-state amplifier and power supply will enable the Navy to replace the Klystron amplifier, which is exhibiting decreasing availability; this directly addresses the Navy’s requirements. In Phase I, POC will demonstrate the feasibility of the proposed amplifier, by developing a scaled down prototype by combining power of four amplifier modules. In Phase II, POC will design the packaging and prepare a final prototype.

Title:LFA and CFLA Acoustic Sensors
Abstract:Challenges faced today by the U.S. Navy’s ASW forces are due to the increasing number of diesel-electric submarines operated by some nations. These threats faced by the U.S. Navy have become increasingly difficult to locate using traditional passive acoustic sonar due to the advancement of quieting technologies in submarines. Low-Frequency Active (LFA) and Compact Low-Frequency Active (CLFA) sonars were developed to improve the detection range of these quiet submarines. LFA and CLFA were originally designed for use in a deep- water, low-clutter environment. Active clutter has significantly increased as these active sonars moved from deeper water to littoral environments. Adaptive Methods proposes to develop an active adaptive beamformer (ABF) for LFA and CLFA which provides improved active clutter reduction and improved signal to interferer and noise ratio. ABF algorithms ability to suppress loud acoustic interference arriving in the sidelobe region of beams will reduce clutter and improve detection performance. Adaptive Methods proposes to apply our approach to Robust Adaptive Matched Filtering to beamformed data that will improve the detection of weak signals of interest normally masked by loud interference in correlations. The feasibility of our concepts will be demonstrated by use of simulated data and comparison to the existing processing system.

Title:LFA and CFLA Acoustic Sensors
Abstract:This Phase I project will develop an innovative signal processing and information processing concept for improved detection in acoustically noisy littoral waters using existing towed arrays or hull-mounted arrays. These relatively shallow waters have many sources of noise and interference which make it difficult to track the multiple targets with classical filtering approaches such as particle filters or Kalman filtering. It is a multisource problem because of background noise sources and the natural tendency of the multiple signals to overlap. This project proposes an evolutionary approach by building on currently-used detection algorithms using a new probabilistic framework to determine the instantaneous localization (azimuth, range, and depth) of multiple targets and their trajectories in the short-term by spatio-temporal clustering. Autonomous detection and localization using long-term signal clustering with the Bayesian Information Criterion allows targets to be tracked as they move through the noisy littoral space. Outputs from existing systems can also be directly processed by this framework to further improve sonar performance. The Phase I research objectives are to evaluate with underwater acoustic sounds and establish feasibility of the system for improved performance in active clutter reduction that reduces false alarms and improves performance in detection, classification, tracking, and displays.

Title:Using Features to Reduce LFA and CFLA Clutter - MP 14-13
Abstract:Metron has developed a detector-tracker for Mid Frequency Active (MFA). This detector- tracker computes likelihood functions and likelihood ratio surfaces from the un-normalized matched filter output of the MFA system. While doing this we have discovered a number of features that significantly reduce false alarms. The process involves identifying a feature, characterizing its statistical behavior, and developing a likelihood ratio function based on the probability distribution of the feature’s response when a target is present to the distribution when no target is present. The power and virtue of working with likelihood ratios is that there is a principled and optimal way to combine this feature information with the likelihood ratio surface produced from the matched filter output, namely multiply the likelihood ratios together to form a cumulative likelihood ratio surface. Peaks in this new surface become candidates for detections. When combined in this fashion, the likelihood ratios from a well-constructed feature will reinforce the peaks due to targets and reduce those due to clutter. This will reduce the false alarm rate without lowering detection probability. We plan to adapt and apply this process to the LFA/CLFA tracker Metron is developing under ONR funding.

Title:Shock Tolerant, Solid State, Submersible, Emergency Transmitter
Abstract:The Navy has identified the need for an improved and reduced cost Emergency Buoy Transmission System for the Ohio Class Submarine Replacement Program. Challenging reliability, maintainability, environmental, cost, and space weight and power (SWaP) objectives require innovations in several key design areas. To meet these requirements, Progeny will design a cost effective, highly shock survivable, and compact Class E amplifier assembly to replace the current system. Our focus for this effort will be to design a compact transmitter that can reliably survive the extreme environments (including shock levels exceeding 4000 g’s) experienced by this safety critical system. Our transmitter assembly will incorporate modernized electronics, innovate and compact packaging (such as embedded components), robust shock hardening, and efficient thermal management strategies. Incorporation of new technologies will improve mission performance and increase transmit windows due to improved transmitter efficiency. To accomplish these improvements, innovative technology approaches will be identified and detailed electrical and mechanical designs will be developed. This effort will include comprehensive dynamic shock, and thermal Finite Element Analyses of the transmitter assembly

Title:The RUBIK Algorithm for Characterizing Sparse Interleaved Emitter Pulse Trains
Abstract:SEWIP Block 2 will utilize a fast-scanning ES receiver to rapidly acquire pulse data in the wideband threat spectrum. Depending on the scanning parameters, large gaps in pulse trains may confuse current deinterleaver technology, and ultimately confuse Emitter ID, which is already a challenge given densities of hundreds of emitters and therefore thousands of pulses to be associated into individual pulse trains. Azure offers a two-pronged approach to solving this problem: Leverage Azure’s Novel Emitter Parametrics NAVSEA SBIR; and, Azure’s proposed new RUBIK algorithm, which combines the functions of Deinterleaver and Emitter ID into a single processing block. In Phase I, Azure will utilize actual radar data collected in our lab, and also work with the Navy to obtain simulated data which is representative of the problem in the context of SEWIP Block 2.

Title:Development of Algorithms for Characterizing Interleaved Emitter Pulse Trains with Complex Modulations
Abstract:This SBIR develops clustering and de-interleaving algorithms to process non-contiguous clusters of pulses, collected from acquisition scanning receivers periodically sampling (spectrally, spatially, and temporally) subsets of the signal environment, to better perform Emitter Identification (EID). The end result will be improved correct EID, with confidence level, and a corresponding reduction in the size of candidate emitter lists and ambiguities. It addresses a wide variety of challenging emitter signal classes for which current approaches are noted to have problems (RF agility, pulse repetition frequency (PRF) agility, pulse-width agility (PW), combinations of RF/PRF and/or PW agilities, and complex modulations). It also addresses multiple interleaved PRFs of different pulse-widths and modulations generated from single emitters.The approach leverages and refines existing RAS algorithms and software modules (C/C++ and MATLAB) such as clustering using multiple parameters measured on a single pulse, time based de-interleaving, RF Agile clustering, and cluster correlation grouping clusters collected in non-contiguous time intervals.Approaches are assessed and selected for PHASE II software development and demonstration within the SEWIP Block II architecture. During and after Phase II, RAS will work with SEWIP Block II prime Lockheed Martin and the government to define, install and demonstrate the technology on a suitable test-bed.

Title:Robust Emitter Classification Using A Scanning Receiver
Abstract:In this research effort, Vadum will evaluate multiple classification techniques to mitigate the effects of corrupted measurements from the new scanning receivers in the SLQ-32 electronic warfare suite. Vadum will create an Automated Optimization Environment (AOE) to train three advanced classification techniques using existing electronic intelligence (ELINT) databases; these techniques will be tested using corrupted radar emitter intercept measurements that are noisy, biased, and missing pulses. Vadum’s innovative AOE approach, which optimizes parameters of the classifiers, reduces risk by allowing a wide range of classification techniques to be quickly optimized and evaluated. Many classification candidate techniques exist, each with advantages and disadvantages; during Phase I Vadum will evaluate three renowned techniques and determine which of these best solves the problem presented in this SBIR topic. Classification techniques to be evaluated include: Neural Network (NN) (tried and true), Support Vector Machine (SVM) (currently best in class), and Random Forest (RaFo) (state of the art). NNs are known to be robust and generalize well when not over-trained. SVMs are optimal, in the sense of maximized decision boundary margin, when classes are linearly separable. RaFos have been shown to have similar classification performance to SVMs but with less computational complexity. The study performed in Phase I will answer the question of which classification technique minimizes the emitter candidate list in the presence of biased, noisy, and incomplete scanning receiver measurements.

Title:High-Efficiency Propulsion for EMATT Sprint Speed Capability
Abstract:Aurora Flight Sciences and the Lockheed Martin Sippican propose to develop a new propulsion system to increase the top speed of an EMATT (Expendable Mobile ASW Training Target) vehicle to 14 knots. Aurora will perform systems-level analysis to determine propulsion system requirements and component-level specifications. Aurora and Lockheed will work with top battery manufacturers to develop a safe, high energy-density battery that provides sufficient power and capacity to meet the sprint speed performance requirements. Aurora will size a high-efficiency motor matched to a novel propeller design which will ensure efficient operation across the range of EMATT operating speeds. Efficiency gains will be realized through the design and optimization of a new fixed-pitch propeller which matches the propeller load to the most economical motor operating conditions. Component- level and total-vehicle performance will be estimated analytically to assess performance and stability. Vehicle safety will be assessed, risk reduction activities and opportunities to improve vehicle performance will be identified, and a Phase II development plan will be identified. In the Phase I Option, Aurora will investigate a hydroelastically tailored propeller to further improve propeller and motor efficiencies across all operating speeds.

Title:Sprint Speed Capabilities for an Antisubmarine Warfare (ASW) Training Target
Abstract:Significant resources are required to increase the sprint speed capabilities of miniature AUVs which are subject to severe weight and volume constraints. This is aggravated when (i) high speed maneuvers are required to last longer periods of time, and (ii) vehicle stability can no longer be guaranteed at high speeds due to vehicle design constraints. In the case of the ASW training target EMATT, the design challenge extends well beyond selecting more powerful motors and high-capacity batteries. As outlined in the solicitation, advancements in motor and battery technology are continuously entering the market. Although those systems have been successfully utilized for a variety of applications, the development of an optimization strategy that (i) combines individual subcomponents such as shroud, propeller(s), shaft, gearing, motor(s), and batteries, and (ii) adheres to stringent design space requirements still poses a significant challenge. To close this technological gap, the NextGen team will leverage previous work and proven methods in order to develop a hydrodynamic optimization tool that guides the selection and/or design process of subcomponents for a vehicle specific propulsion system. The optimization tool will expose several options to compromise between design parameters such as top speed, speed range, required vehicle length and overall endurance

Abstract:Hstar proposes a mobile, advanced, agile, adaptable handling (A3-Hand) system for shipboard mission payload handling. On the LCS seaframes, A3-Hand’s ability to remotely load, unload and transport a wide variety of payloads in and around ISO containers and mission vehicles will immediately improve LCS’s operations efficiency.

Title:Advanced Shipboard Mission Payload Handling System
Abstract:The QED team proposes an Advanced Payload Handling System (APHS) capable of semi- autonomous and/or wireless remotely controlled, omni-directionally maneuvering operations. Selected design candidates will be evaluated with respect to their ability to provide an assured capability of acquiring and lifting both palletized and uniquely shaped payloads from the confines of a standard ISO container or from Twenty Foot Equivalent (TEU) flat-racks and transferring them to the desired location aboard the LCS. The study will focus on the ability of the APHS candidate designs to maneuver precisely on deck in very tight spaces and conduct payload-handling tasks safely whilst the LCS is operating in elevated sea-state conditions. A combination of state-of-the-art engineering analysis tools will be employed to verify the structural design approach and define a safe operational envelope for the APHS under simulated ship motions. Selected APHS candidate designs will be evaluated under the Phase I program comparing their capabilities to defined criteria and metrics developed from the outline presented within this proposal. The results of the study will provide the basis for a candidate system down select and recommendations for a Phase II program to fabricate a full-scale APHS Proof-of-Concept demonstrator for simulated operational test and evaluation.

Title:Airborne Contact Cueing for Panoramic Imagers
Abstract:Areté will build an algorithm capable of real-time performance on panoramic video that rapidly detects low visibility aircraft with minimal false alarms. The team will make use of the on-hand periscope video and APB-13 algorithms to create panoramic inputs to our robust, likelihood-based Bayesian Field Detector (BFD) algorithm. For the Phase I effort, we will integrate and advance the BFD algorithm to detect aircraft and provide cueing information to the operator including an aircraft state vector and detection statistics. Within the scope of this overall solution, Phase I activities will focus on assessing algorithm performance and feasibility of a real time implementation. The Areté team is uniquely qualified to offer the requested capability. Its advanced position is a result of extensive experience in periscope image processing, 360-degree periscope mosaic-imaging, coherent stacking for low SNR detection, precise false alarm mitigation, and efficient highly-parallel algorithm development. The team also benefits from having over 20 hours of real periscope video—including airborne contacts in visible and infrared bands—on hand for algorithm development and testing.

Title:Airborne Contact Cueing for Panoramic Imagers
Abstract:In an effort to improve the current approach for periscope surveillance detection, the Navy is developing a new panoramic mast video sensor. Utilizing both LWIR and EO technology the sensor will provide a 24 hour operational capability in challenging maritime environments. Advancements address operational necessity for rotating the mast and viewing limitations, however, they do not address additional difficulties operators face in reliably detecting aircraft in large quantities of video data. Ability to reliably detect aircraft targets in EO/IR video would leverage the technology to its full potential and increase the effectiveness of human operators. Relevant algorithms should be both computationally efficient and robust under a full range of operating conditions, including cloud clutter, water droplet clutter, day and night, and weather-driven illumination and temperature variations. Toyon Research corporation proposes a suite of parallelizable algorithms based on statistical appearance and apparent change modeling combined with track-before-detect framework that enables detection of aircraft at the farthest possible standoff distance (fewest pixels on target) allowing operators maximum time for target evaluation and response.

Dielectric constant and loss tangent of the composites will be measured from 1 GHz to 20 GHz, and from 75 GHz to 100 GHz over room temperature to 1200C. Flexural strength and thermal shock resistance of the composite will be determined, and Weibull parameters will be calculated to assess the composite’s potential reliability.

Title:High Pressure Diver Breathing Gas Supply System
Abstract:ADA Technologies, in collaboration with SCUBAPRO, proposes to develop an ultra-high- pressure SCUBA system capable of supplying Navy divers with vastly increased air capacity to allow longer submersion time. This system employs multiple small composite cylinders and a custom first-stage pressure reduction regulator coupled with commercial-off-the-shelf SCUBA parts. It is designed to provide more than twice the amount of breathing air while shedding 30% of the cylinder weight without restricting mobility of the diver. With this additional submersion time, divers will have increased operational flexibility resulting in a higher likelihood of mission success. The proposed Phase I program includes regulator design and prototyping, composite cylinder procurement, integration with COTS components, followed by pressure and functionality testing. The critical task of the program is the design and fabrication of a pressure-reducing regulator to step-down ultra-high cylinder pressure of up to 10,000 psi to an intermediate pressure of 140 psi. The first prototype design will be validated through pressure testing at our facilities to demonstrate safe operation and proper gas flow. Following successful proof-of-concept demonstration, the team will fabricate an advanced prototype, leveraging findings from the initial effort and develop a preliminary engineering and manufacturing plan to be refined in Phase II.

Title:High Pressure Composite Air Flasks for SCUBA Systems
Abstract:Current air flasks utilized by the Navy for SCUBA diving weigh about 40 lbs and are rated for 3,000 psi internal pressure, providing 30 minutes to an hour of air supply from a single tank. The Navy desires to increase mission capability for free-swimming divers, but air supply remains the most significant impediment to this goal. Development of smaller air flasks and a regulator system that could accommodate up to 10,000 psi of internal air pressure is sought. However, flasks manufactured using similar materials to those currently in service would be far too heavy and bulky if fabricated to meet this pressure. Lighter weight materials are required.Luna Innovations Incorporated will team with a leading commercial producer of DOT approved composite air flasks to design a flask and regulator system to meet the Navy’s desired criteria. The manufacturer’s extensive experience in the design and manufacture of flasks for DoD, including underwater applications, will be leveraged with Luna’s novel optical fiber strain sensing technology to streamline design. Weight savings will be optimized by intimately calibrating measured material response to design models. Furthermore, this non- intrusive sensing system will enable a means of health monitoring, reducing operational risk and maintenance costs.

Title:Novel, Very Wide-Bandwidth Characterization Technique
Abstract:EOSPACE proposes developing a practical, very-wide-bandwidth electrical characterization technique based on advanced photonic signal processing. The characterization method only requires a high-speed mm-wave source and uses exclusively low-speed optical detection, eliminating the need for high-speed photodiodes. This effort would build on the recent breakthroughs in ultra-wide-bandwidth electro-optic modulator characterization methods at EOSPACE. The proposed technique is a fast, swept-frequency approach and is robust against virtually all common weaknesses in photonic measurement systems, such as optical power fluctuations and spectral changes in the optical source and electrical small-signal limit restrictions. The optical paths in the measurement system are entirely in optical waveguides, optical-bias and alignment-free, and the system has no mechanical moving parts. As the method does not rely on high-speed photodetection, it can be extended beyond 110 GHz to 1THz—merely by changing the electrical signal generator. Additionally, unlike many photonic methods, our characterization method can operate down to a few hundred kHz.

Abstract:Nuvotronics is proposing for this Navy SBIR number N131-059 to develop the key elements to enable broadband sources (1–110 GHz) toward future electronic warfare (EW), communications and radar systems. RF passive components based on waveguide are very low loss but are limited in bandwidth. Components based on substrate material such as ceramic or printed circuit board can provide a broader band of operation but exhibit high loss especially at high frequencies. . To provide RF components with low loss and wide- bandwidth of operation, Nuvotronics is proposing to design new RF passives based on our proven PolyStrata integrated transmission line technology. PolyStrata offers unprecedented performance in propagation loss, wide band operation and linearity, enabling the next generation of low loss passives components. For this proposal, Nuvotronics is offering in this phase I to design an ultra-low loss architecture, which will integrate the different micro- filters, active and passive components needed on a single common PolyStrata monolithic backplane to deliver a 1-110 GHz wide band source.

Title:Subsea Long Haul Optical Transponder
Abstract:The David Ross Group will develop an innovative, miniaturized low-cost undersea transponder for data transmission over long haul underwater cable systems where the signal is generated from an undersea node and integrated with an undersea transmission system while minimizing the use and number of undersea optical amplifiers (repeaters). The David Ross Group will identify how these technical solutions might be integrated into an underwater distributed network to achieve objective data rates, distances, power consumption, and minimal repeater use. Specifically, the proposed study will focus on developing an undersea transponder and supporting electronics, that meet the minimum requirements, but targets the stretch objectives specified.

Title:Binary Static Previrtualization
Abstract:Modular software development helps enable application developers to quickly write sophisticated applications. However, in most instances only a small fraction of the functionality included in a particular software components is needed. Not only is there a performance cost, but the prevalence of security vulnerabilities suggests that even unused functionality in binaries and shared libraries can be dangerous. To address the problem of extraneous functionality, SRI International has developed, static previrtualization, a static analysis and code specialization technique that uses partial evaluation to remove unused functionality. SRI has developed a prototype tool, Occam, that performs static previrtualization on LLVM bytecode.Galois proposes to work with SRI to extend Occam to support static previrtualization of binaries. Galois will develop a binary disassembler capable of generating LLVM bytecode from binary machine code. This will allow Occam and other LLVM-based optimization tools to be applied to existing compiled machine code. This will make it easier for static previrtualization to be adopted in industry, and facilitate applying previrtualization to entire systems.

Title:Advancing the State of the Art in Artificial Intelligence for Simulation Training
Abstract:The USMC has an immediate need for a framework and infrastructure with which state-of- the-art AI technologies can be integrated to replace simplistic CGF behaviors in virtual simulation platforms such as VBS2. SoarTech, along with our partner Aptima, proposes to apply our vast expertise in the design, development and integration of artificial intelligence technologies, bringing it to bear to help develop more realistic entity-level scenarios for USMC simulated training. Most crucial to our work will be the design and development of a full infrastructure, called SERUM (Simulated training Exercises with Robust Unmanned Models) to support advanced AI for the USMC’s simulation technology portfolio. This infrastructure will allow for robust, unmanned entities (Soar-based and otherwise) to exist in both constructive (e.g. OneSAF, JSAF) and virtual (e.g. VBS2) simulation environments simultaneously, and will also include the necessary hooks and mechanisms to allow entities to both perceive the world and make actions within it. Using SERUM, we will then develop prototype robust intelligent agents (and apply existing agents) that can serve as robust, tactically viable role-players for a particular domain (e.g. JTAC training) that require minimal babysitting and maintenance on the part of scenario operators.

Title:Crowdsourcing using Intelligent Supervision to address Information Requirements in Crisis Situations (CRISIS)
Abstract:Marine Expeditionary Units (MEUs) are often first responders, addressing crises such as natural disasters and regional instability. To adequately respond, they must quickly and accurately analyze large amounts of raw information. Fortunately, through crowdsourcing, there are vast, knowledgeable, and unexploited resources in local and military populations that can address information requirements (IR) and analysis needs. However, Marines need an effective system to use these distributed human processing resources. MapReduce addresses a similar distributed parallel computational processing problem, but not the inherent diversity of human resources. Inspired by MapReduce, we propose to design and demonstrate a system for Crowdsourcing with Intelligent Supervision to address IRs in Crisis Situations (CRISIS). CRISIS provides a crowdsourcing algorithm to employ diversely skilled crowds to address problems for MEUs, focusing on four key components: (1) an evolvable ontology of crowd capabilities to drive human-centered problem partitioning; (2) probabilistic models of crowd skills and preferences to not only identify crowd resources, but understand their capabilities; (3) a market-based optimization system to perform load management and mapping while addressing a scarcity of properly skilled resources to address tasks; and (4) a combination of semantic reasoning and provenance modeling to reduce solutions, identifying consistencies and inconsistencies in the process.

Title:Crowdsourcing as a Map Reduce Job
Abstract:MSI proposes to develop automated mechanisms to dissect incoming queries and engage appropriate cloud-based resources to address them. To automate this process, we propose iterative query refinement between an automated analyzer (called the Matchmaker) and human experts. The Matchmaker will use keyword and semantic analysis to identify query topics. These topics will engage people with expertise in those topics who can either take on the subtasks or provide more accurate topic suggestions. When the task results are submitted, an automated Fusion Engine will compare all results with a description of the expected results (submitted by the task creator) and select the best answer. These mechanisms will extend MSI’s foundational system for massively collaborative problem solving that is being developed for a Phase II DARPA SBIR. Our framework, called ePluribus, allows collaborators to explore two key problem solving phases: understanding the situation that brought about the problem and evaluating actions that can modify the outcome of the situation. Similar to the map/reduce model, ePluribus allows people to 1) decompose complex problems into manageable components (map), 2) asynchronously provide solutions to these sub-problems, and then 3) aggregate the proposed solutions to form a collective solution integrating all significant points of view (reduce).

Title:Crowdsourcing Situational Awareness (Crowd- SA)
Abstract:The basic need in a crisis situation, whether it is a natural or unnatural disaster, political or social unrest, or some combination, is relevant, timely and accurate information, filtered to present the most pertinent data to the decision makers. Commanders have unique information requirements due to short timelines and unknown background data on their assigned Area of Operations. Crowdsourcing data, properly filtered and managed, provides an instant “quicklook” into the human terrain, atmospherics, and current events. This also assists the Intelligence Operational planners to direct their assets to confirm or deny conclusions drawn from the crowdsourcing data. Our solution, implemented as a monitoring system to world events, could act as a “first alert” capability that would indicate an upcoming problem or crisis well in advance of the typical news and intelligence channels. Modus Operandi proposes to develop a crowdsourcing system to analyze and fuse data from witnesses and participants to find relevant information in times of disaster or emerging crisis. The final system will accept input from the crowd, extract events and entities in the context of natural language, normalize the information, and fuse it with data from other sources using cloud-based distributed processing.

Title:Advanced Tactical Cryocoolers for UAV Applications
Abstract:Cryogenic electronics have the potential to revolutionize digital communications from Unmanned Aerial Vehicles (UAVs), but must operate at cryogenic temperatures. Commercial cryocoolers are large and inefficient and are unable to meet size, weight, and power requirements for UAVs. Our approach and the innovation is a reverse turbo-Brayton cryocooler that provides refrigeration at 4.2 K and rejects heat at 77 K through boil-off of liquid nitrogen. The cryocooler is predicted to reduce size, weight, and input power by at least an order of magnitude as compared to the current state-of-the-art 4.2 K cryocooler. The nitrogen boil-off rate is reasonable, enabling missions of up to nominally 8 hours using a small dewar of liquid nitrogen. Successful completion of this program will dramatically improve digital communications from UAVs. During the Phase I project, we will finalize specifications for the cryocooler; design the cryocooler and cryostat; determine the size, weight, and input power for the overall cryogenic system; and perform a proof-of-concept test on a critical cryocooler component. During Phase II, we will build and test a critical cryocooler component or a complete cryocooler.

Title:LN2-Precooled Two Stage Pulse Tube Cooler
Abstract:One of the fundamental implementation challenges for 4K cryocoolers to support superconducting electronics (SCE) is the size of the cooler. For platforms on which there is the possibility of using a “thermal battery,” i.e., a reservoir of cryogenically-cooled fluid that can be used to precool the cryogenic subsystem, there is a tremendous opportunity to reduce the required size of the cryocooler dramatically. For example, the upper stage(s) of expander components can be replaced with a simple two-fluid heat exchanger, reducing expander volume and, more substantially, compressor volume by reducing the required exergy lift. Success on this program is thus expected to lead to insertion opportunities on a wide range of packaging-constrained platforms that would otherwise preclude closed-cycle refrigeration, and in so doing enable the use of high performance SCE-based RF communications electronics on platforms that are presently the exclusive purview of traditional approaches.

Title:Automating Unmanned and Manned Sensor Performance in Demanding Tactical Environments
Abstract:Per the topic description, naval airborne sensor systems are utilizing or are planning to utilize varying degrees of automation in the prosecution of their missions as part of future naval capabilities. The automation must handle very dense maritime surface picture conditions that can exceed 1,000+ surface contacts that quickly become overwhelming for operators to adjudicate. A promising strategy to adjudicate the surface contact picture automatically is to optimally allocate the resources of airborne sensor suites that are typically deployed on manned and unmanned airborne platforms conducting ship self-defense and maritime surveillance operations. Early detection and classification of potential threats is possible using high range resolution and tracking radar. Additional classification is possible by combining EO/IR interrogation, and association with stored data and available off-board information. It is envisioned that a sensor suite resource manager (RM) would be employed to automatically construct the surface picture with the use of classification aids that leverage the merging of information from organic and inorganic sources. It is also desirable that the RM is capable of dynamically tasking the platform via flight profile changes in response to the evolving surface picture, taking into account mission profiles, OPSITs/TACSITs, platform kinematic capabilities, airspace restrictions, and threat profiles. In addition, the RM must have situational awareness of the local airspace traffic in order to conduct the mission effectively and maximize on-station time.

Title:Automating Unmanned and Manned Sensor Performance in Demanding Tactical Environments
Abstract:The US Navy uses manned and unmanned airborne platforms for ISR missions in challenging littoral environments with non-segregated airspace, restricted operating regions, and sensor occlusions, while tracking and classifying potentially hundreds of targets. In this Phase I effort, we propose to design an integrated planning tool for airborne ISR platforms that can generate vehicle routes and sensor schedules in real time that satisfy vehicle dynamic constraints, airspace constraints, and sensor constraints, while serving the ISR mission objectives with varying degrees of specificity, and maximizing on-station time. The route planner conducts a tree search over a parameterized maneuver space so paths are kinematically feasible. The search samples neighborhoods in the space and obtains bounds on the various constraints and information objectives to determine promising regions to explore. This approach permits the use of complicated dynamic constraints such as sensing geometry, aircraft avoidance, and fuel consumption. The sensor scheduler selects particular tasks and start times, refining the route as necessary to comply with sensor resource constraints and achieve the given information goals. Multiple plans are presented to the operator if goals are in conflict or several different solutions exist, allowing the operator to apply mission-level judgment in directing the platform.

Title:Electromagnetic-Attack-Resistant Modulator
Abstract:This Small Business Innovation Research Phase I project will develop an electro-optic modulator that can withstand electromagnetic attacks (EMAs) in all their forms: nuclear electromagnetic pulse, high-power microwave, and ultra-wideband. The modulator is a modified form of our state-of-the-art low-Vpi lithium niobate Mach-Zehnder modulator, so it will simultaneously enable a low-noise-figure photonic link and provide protection from EMAs. A microwave-photonic link using this modulator can be used wherever a photonic link is normally used, or it can be added to other electronic systems to provide a protected path for received signals that isolates the electronic system from its antenna. The hardened microwave-photonic links developed here eliminate any metallic connection between the antenna and the protected system, the protection is always on (instantaneous response), and the recovery time after a pulse is very short (~250 microseconds); to our knowledge, this performance is superior to any existing protection technology.

Title:Electromagnetic-Attack-Resistant EO Polymer/Sol-gel Modulator
Abstract:RF photonic links provide an attractive approach to minimizing the impact of an electromagnetic attack on defense and commercial communications infrastructure. A key component in an RF photonic link is an electro-optic (EO) modulator, and current commercially available EO modulators are not able to withstand the 10kW peak power pulses that can results from an electromagnetic attack, such as an electromagnetic pulse (EMP). In the proposed program, TIPD, LLC will develop design concepts and materials candidates for a novel EMP-hard modulator based on its proven EO polymer/sol-gel modulator platform, which has achieved low drive voltages (~ few volts), low insertion loss (~ 5dB or less) and high speed operation suitable for RF photonics links. The EMP-hard properties of the modulator will derive from the unique, dielectric breakdown suppression properties of TIPD’s sol-gel materials, which have been used in high dielectric breakdown strength applications like claddings for EO polymer modulators and high energy storage density capacitors. The Phase I program will comprise modulator design, materials selection, electrical/thermal modeling, and high frequency/high voltage materials characterization, while the Phase I Option will include prototype phase modulator development and roadmapping the testing needs of Phase II.

Title:High Efficiency, Thermally Integrated Bio-fuel Steam Reformer for Solid Oxide Fuel Cells
Abstract:Precision Combustion, Inc. (PCI) is proposing an integrated steam reformer and solid oxide fuel cell design capable of very high efficiency and robust transient operation. By virtue of intimate physical integration, without compromising system complexity, the proposed design enables very high thermal efficiency and a readily scalable modular design, made possible by the use of PCI’s high heat flux steam reformer designed to effectively remove heat from the stack. In this Phase I, we will demonstrate operation of a high efficiency reformer with bio- fuels and identify operating maps to minimize start-up and transient time, and through modeling, develop thermally integrated designs for various SOFC systems in both steady state and transient operation. Solid models with sufficient detail to predict volumetric and gravimetric power densities will also be developed. BOP components and parasitic loads will be determined. During the Option period, we will demonstrate stable reformer operation with bio-fuel for 250 hours, and experimentally examine reformer + stack operation at subscale levels. In Phase II we will develop, fabricate, and test the thermally-integrated power generator developed in Phase I on bio-fuels for 1000 hrs, and perform a TRL-5 demonstration of the technology at 10 kWe.

Title:Millimeter Thick, Periodically Oscillating Polarity GaN Grown via HVPE
Abstract:Gallium Nitride (GaN) crystals have recently garnered attention as a candidate for use as a Quasi-Phase Matching (QPM) material for frequency conversion applications such as second harmonic generation (SHG) and optical parametric oscillation (OPO), due to its wide bandgap (3.4eV), high thermal conductivity (220-260 W/m-k), and wide transparency window (0.36-7um). Additionally, recent work has also demonstrated the ability to produce Periodically Oscillating Polarity GaN (POP-GaN) via several techniques. Such periodically poled structures have been used for QPM in other material systems, such as Lithium Niobate, Potassium Titanyl Phosphate, and GaAs, so the demonstration of periodic poling capability in GaN leads to optimism in utilizing GaN for QPM applications. Growth of large area, thick POP-GaN crystals with an embedded periodic polarity structure present several challenges, which if solved, will provide a commercialization route for POP-GaN as a QPM material with higher performance and wavelength range capability than the existing materials in the market today.

Title:Thick Film Growth of GaN for Nonlinear Optics
Abstract:There is an intense search for new nonlinear optical (NLO) materials suitable to wider wavelength ranges, to greater optical intensities and higher output and efficiency. Quasi- phase matched semiconductors show potential, particularly periodic orientation (PO) of thick gallium nitride films (PO-GaN) to meet many of the NLO device requirements if new methods of PO crystal growth are developed, especially hydride vapor epitaxy (HVPE). For the proposed project, Physical Sciences, Inc. (PSI) will team with the GaN Lab at Ostendo Technologies, a premier developer and provider of III-nitride films and devices, and a world leader in the methods of HVPE since 1997. PSI has developed orientation-patterned (OP) GaAs crystals for applications in NLO devices, and is now a commercial supplier of OP- GaAs. The combined team will provide a technical effort comprehensive from crystal growth to NLO devices and laser systems as well as a strong pathway to commercialization of the developed NLO devices in Phase III. In Phase I the team will demonstrate HVPE methods to grow nitrogen- and gallium-polar films at nearly equal rates to moderate thicknesses and characterize the films. Phase II will optimize the HVPE methods for much thicker PO films and demonstrate NLO devices fabricated from these films.

The system will be designed to retrofit existing aircraft. The drive system will consist of a permanent magnet (PM) generator attached to the tail rotor output of the turbine gearbox and a direct drive PM motor replacing the tail rotor gearbox. Power electronics and electric cables connect the generator to motor. LaunchPoint Technologies will use its ironless dual Halbach array axial flux motor/generator technology and electric motor/generator drive technology to achieve significant weight savings and efficiency gains over designs based on conventional iron core motors; thus enabling a technically and commercially viable solution that has eluded the aviation industry in the past. The drive system is estimated to add 7 to 9 kg to the vehicle while increasing vehicle efficiency, reliability, flyability, and operational performance. Within the phase I activity this estimate will be confirmed with detailed engineering design and modeling. Additional design optimizations and features will be evaluated that have the potential to further reduce the mass or increase the utility of the system.

Progeny Systems Corporation proposes to develop an innovative Check Range Sensor Pod to allow ships and submarines to measure underwater magnetic and acoustic radiated signatures at forward sites removed from shore-based fixed monitoring facilities. The expendable pod will be reconfigurable to take measurements at a set depth down to 300 meters. Launched from the submarine, the Check Range Pod deploys a sensor array, tracks its relative position, and maintains a command and control datalink. Upon completion of recording events the submarine retrieves the processed sensor data and the pod scuttles.Our Phase I effort will design and demonstrate feasibility of the magnetic and acoustic sensors, develop data processing algorithms, and develop a high level pod design with deployment and employment operational concepts.

Title:Check Range Sensor Pod
Abstract:Undersea operational supremacy is foundational to continued U.S. security. This supremacy is partly rendered through clandestine operations. Though Navy submarine and surface ship signatures are measured at land-based silencing facilities or test ranges at sea, these signatures can degrade over time for a variety of reasons, making the platform more vulnerable to detection. Vulnerability levels can be exacerbated if signature degradation occurs. As it is expected that certain missions present high levels of risk, it would be advantageous to create a self-test range at sea rather than transiting to the nearest permanent installation.SeaLandAire Technologies, together with its partners will utilize our extensive experience in expendable Navy sonobuoy platforms to develop an inexpensive, simple, yet highly functional expendable sensor pod to autonomously characterize submarine signatures for increases in in-situ tactical awareness. This in-situ calibration sensor pod will be deployed from a submerged submarine utilizing existing platform capabilities. It will be able to measure underwater magnetic and acoustic fields, with E-fields measured by proxy through their induced magnetic response. The pod will collect meaningful and timely data, while remaining covert.

Title:Novel Advanced High-Density Materials for Hypersonic Nosetips
Abstract:Future hypersonic sea-level launch systems require high-density nosetips that can handle extreme heat loads in highly oxidizing conditions, survive >30 kg axial mechanical loads, >10 kg transverse balloting loads, thermal shock from surface temperature rise of 2000°C/sec from a Mach 8 launch with point heat fluxes of 4500 BTU/ft2-sec. Multicomponent functionally graded materials with densities >15 g/cc are necessary for a nosetip to meet the identified launch requirements. Only a few materials meet the density requirement but do not meet the oxidation resistance leading to multicomponent functionally graded materials combination requirements. A high-density core will be utilized and functionally graded utilizing plasma transferred arc (PTA) processing to oxidation resistant compositions which meet nosetip requirements for the duration of flight. Compositions will be optimized with characterization including the severe thermal shock test and arc-jet testing with samples and subscale nosetips delivered to the Navy.

Title:Innovative Nosetip Materials and Designs for Hypervelocity Projectiles
Abstract:The Navy is developing high speed projectiles for a variety of missions including ship defense, surface fire support, and prompt global strike. Inertial loads and high muzzle velocities impose severe operational conditions on the nosetips and suggest they should be made from refractory metals. While metals provide sufficient density for aerodynamic stability, they react to form low melting compositions that can damage the projectile. Other high temperature materials like graphite or carbon-carbon are too light to maintain stability. The proposal seeks to develop multi-material nosetip designs that employ a thin coating or small tip applied to a dense substrate. The Phase I program will select substrate and coating materials to address thermochemical stability and projectile performance. A preliminary trade study will rank important material parameters by using thermostructural equations to compute inertial stresses, temperatures, and thermal stresses. Fabrication techniques considered in the Phase I will include adhesive bonding, brazing, and HIP-induced diffusion bonding. In the Base effort nosetip configurations will be selected and fabricated. In the Option, they will be evaluated with tensile and flexure tests of bonded interfaces. The Phase I effort will be performed by Materials Research & Design, Inc. (MR&D), Exothermics, and Southern Research Institute (SoRI).

Title:High Density Nosetips for Hypersonic Projectiles
Abstract:The Navy is developing weapon systems capable of launching inert projectiles for long- range surface fire support and missile intercept applications. Inert projectiles offer significant logistical and safety advantages over conventional chemical propellants or explosive ordnances. The launch conditions of future hypersonic projectiles will put extreme mechanical and aerothermal loads on the projectile nosetip. These conditions combined with the high-density requirements present a significant materials challenge. No economical monolithic component is projected to survive the extreme conditions immediately after projectile launch, followed by less severe conditions during flight to target. The objective of this proposed effort is to develop and demonstrate an innovative multi-layered material system that is capable of surviving the extreme conditions immediately after projectile launch, followed by less severe conditions during flight to target. The concept is based on a tungsten core with a fracture tough oxidation resistant coating and an outermost sacrificial layer. An ablative layer is intended to dissipate absorbed thermal energy from aerothermal loading, thereby limiting steep thermal gradients in the underlying oxidation protection layer. Thermo- structural modeling will guide the selection of appropriate materials and geometries for each layer. Upon completion of modeling, demonstration articles will be fabricated and evaluated via microstructural characterization and high heat flux testing.

Title:Ablation-Resistant High-Density Hypervelocity Projectile Nosetip
Abstract:This project will develop and demonstrate a high-temperature ceramic-coated tungsten nosetip for hypervelocity projectiles. The ceramic coating will delay oxidation, which causes increased surface roughness, boundary layer transition, much higher heat transfer rates, and substantial ablation of tungsten and carbon-carbon materials. If laminar flow over the nosetip can be maintained, tungsten’s properties enable it to heat-sink the incident aerodynamic heating and avoid ablation for the Mach 8 launch condition of interest. Development of the ceramic material and coating process will build on our prior ceramic- coated tungsten experience. Phase I will include fabrication and characterization of oxidation-resistant ceramic coated tungsten nosetip specimens.

Title:Reduced Cost 2700F CMC Component Manufacturing
Abstract:In this Navy Phase I SBIR Program, MATECH proposes to leverage its lengthy experience in ceramic matrix composite (CMC) fabrication with recent advances in Field Assisted Sintering Technology (FAST) to demonstrate dramatic cost reduction and improved CMC performance. FAST is also known as “Spark Plasma Sintering” (SPS). MATECH proposes to team with Thermal Technology Inc., the leader in SPS processing and equipment manufacturing, in executing this proposed program. As part of its “Defense Wide Manufacturing Science and Technology Program,” OSD has separately identified both CMCs and FAST (Frequency Assisted Sintering Technology) as key areas of interest. This proposed effort aims to integrate these two OSD identified manufacturing science and technology focus areas. As will be described in more detail later in this proposal, field assisted sintering technology can consolidate materials in as short an active process time as 2 minutes! FAST has been demonstrated for metals, glasses, ceramics, and nano- composite materials. Little information is available in the public domain, however, about the application of FAST to CMC fabrication. Given the lack of an experience base in applying FAST to CMCs, MATECH proposes initiating this effort by focusing on the fundamentals.

Title:Rapid Fabrication of SiCf/SiC composite via Field Assisted Sintering Technique for Turbine Applications
Abstract:State-of-the-art manufacturing cost for SiC matrix composites CMC components is still very high due to long lead times despite of many research efforts. ScienceTomorrow, in collaboration with Applied Research Lab of Penn State University and its OEM partners, will investigate ceramic fiber-reinforced ceramic matrix composite fabrication via a novel field assisted sintering technique. Under the concurrent application of high pulsed current density, pressure and temperature the green structure will be consolidated. Processing- microstructure-properties relationships will be established first empirically during the Base Period and numerically in the option period to allow complete exploitation of the benefits of the novel processing approaches. The research will utilize multi-scale material characterization and integrated multi-scale multi-physics computational modeling for developing processing-properties-structure correlation. The success criteria are set in comparison to current fabrication methods: (a) Chemical Vapor Infiltration, (b) Melt Infiltration, and (c) Polymer Impregnation Pyrolysis. ScienceTomorrow will collaborate with an OEM for process optimization and commercialization that will allow the OEM to exploit the benefits of the FAST processing method for SiCf/SiC turbine components. Ultimately, the FAST process will enable the production of more affordable 2700°F capable CMCs.

Title:Lightweight Fiber Reinforced Transparent Composites for Armored Ground/Sea Vehicles
Abstract:The main objective of this work is to develop and commercialize light-weight transparent composites with high tensile strength, toughness and impact resistance. Novel techniques will be developed for the design and manufacturing of these lightweight composite materials with improved blast resistance, energy absorbing capability and thermal properties. HABSonic LLC in collaboration with Missouri S & T will perform research on advanced materials for transparent composites. The optical transparency is achieved by modifying the refractive index of the resin matrix to match with the refractive index of the glass fiber. Different variables affecting the transparency during the resin processing and manufacturing will be optimized to produce transparent composites. Continuous fiber reinforced transparent composite panels of various orientations and thicknesses will be manufactured and evaluated to meet specific threat levels. The performance of the transparent composites will be studied by laboratory tests. The experimental results will also be validated with the finite element simulations. Optically transparent composites will find immediate application in military tactical vehicles. This program will meet the Navy’s need to develop superior transparent armor systems for force protection.

Title:Nanofiber Functionalized 3D S-Glass Reinforced Transparent Ballistic Composite
Abstract:Transparent armor usually ranks among the heaviest of all materials on tactical vehicles per size and weighs significantly more than opaque armor at the same protection level. This is due to the large thicknesses required to provide the required ballistic protection. For this reason, transparent armor is one of the first places engineers look to reduce overall weight, leading to the reduction in size of transparent armor windows, significantly restricting the field of view afforded to military personnel making them more vulnerable to outside threats. Novel material solutions are required to reduce the weight and thickness relative to current transparent armor. To this end, Luna Incorporated proposes a transparent three dimensional woven S-glass fiber reinforced polyurethane composite armor material. The S-glass fibers will be specially coated with a nanofiber functionalized sol-gel interface layer to provide enhanced fiber matrix interaction. The sol-gel layer will also be formulated with a tuned refractive index and coefficient of thermal expansion to maintain optical clarity during temperature changes. The resulting transparent armor material will be lightweight and environmentally stable allowing for enhanced multi-hit ballistic performance.

Title:Breakthrough Lightweight Transparent Armor Technologies
Abstract:This proposal offers the demonstration of an advanced lightweight transparent armor that combines fused silica glass, GeminiTM spaced armor technology, advanced QuintiumTM polymer and a proprietary interlayer (TAS1411) to reduce weight by over 30% of the current state of the art. Ballistic testing will be completed on a 52 psf single laminate conventional design (control) and three fused silica based designs (36 to 38 psf). Environmental testing will demonstrate that these materials also increase the armor’s durability, as the materials used have been shown to be temperature, moisture, and delamination resistant. This SBIR proposal is unique in combining four material systems that are currently available and utilizing them in a novel method to make an advanced lightweight transparent armor.

Title:Multi-spectral, short-pulse, high-pulse-energy laser transmitter
Abstract:The Navy SBIR topic solicits the development of a 4-color laser system that enables the detection of ocean mines on the beach and floating/submerged mines in the ocean. Q-Peak and PSI have collaborated to submit a proposal that leverages the laser system development expertise of Q-Peak and the ocean LIDAR modeling experience of PSI to provide an exceptionally strong development team to meet Navy requirements. During the Phase I program a study effort to (1) guide the selection of the laser wavelengths and (2) develop an innovative, compact, multi-spectral laser transmitter based on the combination of an efficient, high-energy, fundamental laser source and nonlinear optical frequency converters suitable for EO based mine detection. The output wavelengths will span across the visible and near infrared spectral region to enable discrimination between targets, separating mines and vegetation. The primary objective of the Phase I Option program is to develop the initial layout of the transmitter and provide capability description of the unit to be built during the Phase II effort. The laser system designed will meet requirements on SWaP parameters to support deployment on a tactical unmanned Airborne vehicle (TUAV).

Title:Compact Laser System for Airborne Detection of Ocean Mines
Abstract:TIPD LLC proposes to develop a compact and efficient multi-spectral laser system with four spectral bands at 532 nm, 685 nm, 700 nm, and 735 nm for airborne detection of ocean mines. The diode pumped solid-state laser system consists of a master oscillator and power amplifier (MOPA) laser, a frequency doubling laser, and three singly resonant optical parametric oscillators (OPOs). The Nd:YAG thin disk based MOPA laser can generate 2.5 J pulses at 1064 nm with width less than 4 nanoseconds, which can be converted to over 1.25 J pulses at 532 nm through a frequency doubling system. The 1.25 J pulses are split into the desired 500 mJ pulses at 532 nm and three 250 mJ pump lasers for three OPOs that produce 150 mJ pulses at 685nm, 700 nm and 735 nm, respectively. In this phase I program, we will focus on the design of the whole laser system and demonstrate high efficiency frequency doubling and OPOs using advanced quasi-phase matched crystals. Meanwhile, the capability of a thin-disk MOPA laser to produce < 4 nanosecond pulses will be demonstrated. Modeling and simulation on the performance of the whole laser system will be carried out.

Title:ODETTE - Automated Model Learning and Simulation of Carrier Deck Operations
Abstract:Unmanned and partially autonomous aerial systems (UAS) and intelligent decision support systems have become integral components of emerging large-scale cyber-physical systems that will be involved in future military operations. Aircraft carrier decks will be central to many such operations involving multiple UAS, traditional piloted aircraft, sensory equipment, and human operators. Aurora Flight Sciences proposes to develop an algorithmic toolkit, called ODETTE (Observation-based Discrete Event Training and Test Environment), for automatically modeling carrier deck operations based on observed traffic flow data. The proposed research will enable analyses and simulations of future carrier deck operations involving new elements such as UAS and autonomous decision support systems.The proposed research is summarized as follows: We will develop a Markov Decision Process model of carrier deck operations, and survey various existing algorithms for learning of unknown state transition relations in MDPs. To address scalability, we will investigate modifications of these algorithms that are incremental and operate in a multi-resolution framework. Finally, we will develop a relatively high-fidelity software simulation of carrier deck operations, including the simulation of various sub-systems and human operators involved. This simulation environment will be used throughout the duration of the proposed research for validation and testing of the model generator.

Title:Automated Discrete Event Modeling of Aircraft Carrier Deck Operations
Abstract:Aircraft carrier deck operations require a high degree of coordination to maximize efficiency and safety. The current operational paradigms have evolved over many decades of experience. However, the anticipated introduction of unmanned aerial vehicles (UAVs) and other automated systems are likely to require major changes to existing operational procedures to maximize utility. Modeling is an attractive approach for optimizing future operational procedures, but baseline models of the current operational procedures do not exist and cannot be easily formulated. What is needed is a system that can monitor current operations and translate the observed behaviors into a model. Creare will use novel machine vision techniques and Radio Frequency Identification (RFID) technologies to observe deck operations and identify discrete events. We will develop model-generation algorithms to use these observed discrete events to create executable sub-models associated with each primary task. These sub-models will then be combined into a global model of deck operations. In Phase I, we will demonstrate the basic framework of our approach in a laboratory setting, and in Phase II, we will extend the technique to a more complex environment representative of aircraft carrier operations. In Phase III, we will apply the technique to an actual carrier environment.

Title:TraceLogic; Automated Rule Learning from Data Traces
Abstract:KBSI proposes to research the development of methods, process and algorithms to decipher the hidden rules or logic of complex traffic patterns – traces of aircraft, people and equipment on Aircraft Carriers. We call this system that performs “automated rule learning from data traces” - TraceLogic. Operations on aircraft carriers are described as controlled chaos. Complex organizational systems such as onboard carriers adapt and learn and hence do not operate on predetermined low level rules, but rather on high level guidelines. Critical situations that have never been seen before are best tackled by such an adaptive and well trained organization. The main outcomes of the proposed TraceLogic project are: (i) research of the design and demonstration of methods, process and algorithms to decipher the hidden rules or logic of complex traffic patterns, (ii) research of the development of distributed sensor fusion architecture combining knowledge of aircraft carrier operations and sensor capabilities to generate trace data; and (3) eventual integration with existing virtual carrier simulation systems and programs, to accelerate commercialization. Our solution will likely produce significant long term benefits that address the technical and pragmatic problems associated with improving the performance and capability of our aircraft carriers, doing more with less.

Title:BeaconLess Adaptive-optic System & Technology (BLAST) for HEL beam control
Abstract:Effective performance of prospective energy-delivering laser systems requires a beaconless adaptive optic method capable of correcting moderate to heavy atmospheric distortion of high-power beams. The innovative method described here implements a beaconless sensor based on the collection of target-scattered light. Post-processing of the beacon-detected field will allow retrieval and complete characterization of the turbulence-perturbed wavefront. During the Phase I program we will perform detailed theoretical analysis, modeling, design and integration of the BLAST breadboard. The proof-of-concept BLAST breadboard will demonstrate the detection and characterization of wavefront aberrations and the ability to compensate for distortions in simulated perturbations equivalent to Rytov > 0.3. In Phase II a highly-developed prototype-level BLAST system will be tested and proven in realistic field environments.

Title:Advanced Adaptive Optics (AO) for Laser Weapons in Heavy Turbulence
Abstract:Adaptive optics are needed for high-energy laser (HEL) weapon systems when performance is limited by atmospheric turbulence. This typically requires adding an illuminator laser to produce a beacon by reflection from the target surface. Since a small spot is needed, the laser must be projected from the main aperture, complicating the optical design. With this type of beacon, performance is often degraded by speckle, spot size, and branch cuts. The mid-wave infrared (MWIR) thermal emissions from the spot heated by the HEL can also be used as the beacon. This beacon would not be affected by speckle and would have fewer or no branch cuts. We propose using finite element analysis, scaling law and wave-optics modeling, to do a detailed study of this concept.

Title:Sensing and Representing Negative Effects of Motion (SERENE)
Abstract:Exposure to motion degrades operational effectiveness across the Navy, with results ranging from simple motion-induced interruptions (MIIs) to more severe perceptual, cognitive, and motor deficits. Even those who do not suffer from acute motion sickness often experience some level of sopite syndrome, characterized by persistent fatigue and drowsiness. While many research efforts have investigated motion sickness symptoms, there has been little progress in developing real-time sensors for assessing motion exposure and related performance degradation. This capability is needed by the Navy to ensure mission success. To provide this capability, we propose to design and demonstrate a framework for Sensing and Representing Negative Effects of Motion (SERENE). SERENE has three parts: (1) a suite of inexpensive and unobtrusive sensors that synchronously collect physiological, behavioral, and environmental indicators of motion exposure; (2) a fusion engine that combines Complex Event Processing for real-time extraction of indicators from raw sensor inputs, with probabilistic models to detect motion sickness symptoms and MIIs from those indicators; and (3) a hybrid suite of cognitive models that analyze degradation to perceptual, cognitive, and motor performance based on fusion results. Combined, these components provide a real-time assessment framework to detect, predict, and potentially prevent negative effects of motion exposure.

Title:Next Generation Electronic Support Measures Trainer for Submarines
Abstract:Sonalysts will develop and demonstrate a game-based adaptive training system for AN/BLQ- 10 ESM operators that extends the approach developed for Passive Narrowband Sonar operators in the APB-13 Narrowband Adaptive Trainer. The game elements include a student avatar whose appearance reflects student progress, medals for accomplishment of major LOs, scoring that rewards consistent correct response, and animations that reflect correct and incorrect answers. The adaptive algorithm relies upon teaching by question and answer, with feedback that evaluates the response, provides the correct response, gives hints for making a correct response, and foreshadows future LOs. Eye-tracker measurements will evaluate student performance and tailor feedback to student actions. Sonalysts will conduct feasibility studies to determine the best method of injecting signals and noise into individual subsystem processing algorithms, considering both recorded and simulated signals. The objective will create realistic display response on the AN/BLQ-10, so the operator is naturally trained on the displays and controls of the installed equipment. In addition to the embedded algorithm, Sonalysts will investigate the feasibility of creating a PC-based emulator for the AN/BLQ-10 displays and controls, creating a realistic representation of the same pre- processed signals. This approach will reduce development costs and also support additional shore-based delivery modes.

Title:Compact Off-board Passive Target-Discriminator
Abstract:Our system concept is based on a number of ultra-low power “remote nodes” that contain: (1) a battery section; (2) a sensor section (3) and electronics section. The remote nodes will automatically detect and classify high value targets to type using AD&D’s proven automated detection and classification technology. The remote node will also extract key kinematics such as bearing in azimuth and declination angle, bearing rate, etc. These key kinematics as well as target classification features will be passed via a covert communicate message to the “Master Node.” The “Master Node” will correlate target contact information from all nodes and develop a tactical picture based on remote node contacts. By combining bearing and contact data from separate nodes which are holding the same contact, a geographic areas of probability (AOP) of target position will be calculated and passed via a covert communicate message to the remote operator or on scene assets such as patrol aircraft, surface ships, or submarines to facilitate a rapid response and reacquisition of the target for fine localization and prosecution.

Abstract:To address the Navy need for a compact off-board passive target discriminator using networked sonobuoys, Physical Optics Corporation (POC) proposes to develop a new Covert Exemplar Low Power Maritime Activity Target-Discriminator (CELPMAT) system based on the innovative data fusion of multi-modal sensors for surface, subsurface, and air target detection. Based on a comprehensive integration of both a COTS array of acoustic vector sensors and total field magnetometers and POC’s novel multiband compound eye based nonimaging optical sensor, this system is able to passively monitor targets in complex environments through cooperative distributed sensing. In addition, the CELPMAT system possesses onboard ruggedized electronics for data fusion and low-power digital processing based on artificial neural networks and covert communications to rapidly detect targets and discriminate vessel intent. The system will be compact enough to fit into half the volume of an A-size buoy. In Phase I, POC will demonstrate the feasibility of the system by providing system-level concepts and preliminary hardware designs validated by simulation and modeling with associated data fusion algorithms. In Phase II, fully functional data collection prototypes will be designed and fabricated for at-sea experimentation to discriminate targets of interest.

Title:High Performance, Miniature, Wideband Signal Generator for mm-Waves
Abstract:OEwaves has pioneered the use of photonics for generation of spectrally pure RF signals. The micro Opto-Electronic Oscillator (MOEO) provides the highest reported spectral purity at Ka-band in a package the size of a postage stamp. This technology, based on OEwaves crystalline whispering gallery mode (WGM) resonator, can be modified to provide wideband tunability, together with its high spectral purity and small SWaP. In the proposed program, OEwaves will utilize the difference in frequency response of modes of different families in a WGM resonator made with electro-optic material to realize wideband tunability. Tunability is achieved by application of a DC voltage on the resonator, which will result in different frequency shifts of transverse electric (TE) and transverse magnetic (TM) modes of the resonator. Two lasers injection locked to each mode will also move in frequency in response to the applied DC field, and their beat on a fast photodetector produces the desired tunable MMW signal. This approach directly addresses the requirements for a widely tunable, high performance and low SWaP signal generator. It also naturally lends itself to the extension of the frequency of operation to the ultimately desired value of 300 GHz. Since the electro-optic effect is extremely fast, the architecture provides sub microsecond agility, limited only to the settling time of the resonator.

Title:Frequency Agile Millimeter Wave (MMW) Signal Generator
Abstract:PSI will leverage our extensive experience and unique capabilities in MMW photonics to design a compact, lightweight, frequency-agile MMW source combining wide, continuous, rapid tunability with superb phase noise and moderate output power. Such a source will have extensive commercial applications in next-generation wireless communications, as well as military applications including reconfigurable and covert communications and electronic warfare. Our photonic system multiplies and upconverts a low-noise, low-frequency reference signal onto an optical carrier (laser) using ultra-broadband electro-optic (EO) modulation. Modulation sidebands injection lock a second laser to a frequency offset from the first by a selectable multiple of the reference. EO modulation is both coherent and ultra- broadband, rendering the lasers mutually coherent, while oscillating at a widely tunable frequency separation. The locked lasers combine on a high-speed photodiode (PD), generating a beat tone at their frequency difference, eliminating optical phase noise. Our concept has been validated in benchtop experiments (Nature Photonics paper); in this effort we will design and specify requirements for an integrated module, based on a silicon- photonic circuit comprising laser cavities, waveguides, couplers, and filters; with hybrid III-V gain integration, packaged with a compact EO modulator, a surface-mounted photodetector, and voltage-controlled oscillator (VCO) to provide the reference.

Title:Frequency-Agile Heterodyne-Driven MMW Signal Generator
Abstract:Conventional generation of a high-quality RF carrier (signal) beyond 50GHz requires high precision cavity engineering that inherently restricts contiguous bandwidth coverage. Worse, even if one were capable of fabricating a set of such stabilized, frequency-dense cavities to mimic discrete 30-120GHz band coverage, the absence of wideband electrical gain in this range would invalidate such an approach. Recognizing this basic limitation, the proposed work will generate a high-quality tunable signal by heterodyning phase-correlated optical tones combining high power and low noise. In contrast to conventional RF-photonics approaches, a high quality tunable RF signal will be derived from a single, shot-noise- limited master oscillator. The new technique unifies, for the first time, the low-noise characteristics of highly coherent master oscillators and high-power heterodyning. In simple terms, the approach combines high-power emitters with very low RIN characteristics, without resorting to high-resonance cavity construction. Specifically, the novelty of the proposed work is reflected in: (a) the first use of tunable injection locking to guarantee true frequency agility to the 300GHz range and beyond; (b) combined phase-noise inhibition and high-power scaling that is otherwise not possible in conventional shot-noise-limited oscillators; and (c) nearly lossless, fiber distribution of the tunable RF carrier with absolute phase reference.

Title:Membrane-Based Deformable Mirrors for High Power Laser Systems
Abstract:The demonstration of polymer membrane deformable mirrors capable of receiving a high- reflectivity coating and handling high energy laser radiation enables the potential for a new generation of low-cost DMs for directed energy weapons. To achieve high actuator count and high speed, a new structural architecture need to be demonstrated. We propose to develop this architecture to achieve a low-cost DM with high reflectivity and scalable to both a large aperture and a large number of actuators while maintaining a high response speed.

Title:Stealth Optimized, Adaptive Assessments for Multistage UAS Operator Selection (Stealth Adapt)
Abstract:Unmanned Aerial System (UAS) operation represents a stressful, cognitively challenging domain where operators are routinely subjected to both occupational and combat stressors and performance failures can have catastrophic effects. Effective performance in such conditions has many dimensions, including technical proficiency, probability of catastrophic failures, mission productivity, resistance to stress symptomology, teamwork, and long-term work engagement. Effective selection methods for UAS operators should accurately, efficiently, and holistically predict these key outcomes. Our solution to this challenge is to develop a customized suite of 1) assessments measuring cognitive skills, non-cognitive attributes and operational stress coping processes embedded within 2) a novel, adaptive, multistage content delivery and protection framework, and 3) optimized via stealth scoring optimization techniques. One key innovation will be a suite of scoring algorithms grounded in data mining advances designed to boost performance prediction. These will be embedded in performance-based assessments that simulate tasks placing considerable demands on executive-level cognitive skills (mental simulation, task prioritization, and real-time replanning). Phase I deliverables, (KSAO ontology, assessment content, storyboards, scoring and adaptive delivery algorithms, cut score simulations), will provide a preview of the full Phase II content suite, and lay the foundation for transition to UASISST and platform- specific systems for unmanned aviation.

Title:Unmanned Aerial System Operator Selection Tools
Abstract:This proposal is to develop new Operator Selection Tools for Unmanned Aerial Systems (UAS). Our goal is to enhance the effectiveness of UAS operator selection by adding to the conventional methodology of selection tests new measures for the new skills and aptitudes associated with the control of intelligent, semi-autonomous robotic systems. Taking this need into account, we have oriented our proposed SBIR project toward the critical aspects of future UAG operations that are inadequately covered in current selection systems. These concern the ability of the operator to work within the two required types of UAS teams, namely: (1) Mixed-Initiative Teams (the operator and single or multiple semi-autonomous UASs). The key mixed-initiative team skill factors will include supervisory control capability and accurate trust in automation; (2) Inter-Personal Teams (the operator, the commander, the mission controller, etc). The optimal formation and functioning of such inter-personal teams will be of critical importance to successful UAS operations. In other words, both near- term and long-term UAS operating requirements will change dramatically as UV technology evolves, and the UAS operator and crew courses will have to change accordingly. As a result, new selection criteria must be added to current criteria to accommodate these changes.

Title:Unmanned Aerial System Operator Selection Tools
Abstract:Traditional selection and training practices are essential initial selection tools that show some general levels of predictive validity overall. However, current Navy selection tools are not good predictors of performance for Navy air system AVOs. In our targeted solution, we utilize proprietary methodologies that combine standard methods for selection and training of industry personnel, such as the training needs assessment and job analysis processes, with our job task inventory to goal directed task analysis mapping process. The results include a powerful linkage matrix product, which combines tasks characteristics (e.g., task difficulty, severity, importance, frequency, etc.) with knowledge, skills, abilities and other characteristics (KSAOs). In turn, this linkage matrix is resourced to identify and develop selection criteria that are expected to be predictive of performance. The primary objective of our selection tool is to screen for applicants that do not meet minimum baseline performance on dimensions that are hard or impossible to train, such as innate aptitudes, predispositions, and other individual antecedents or precursors. Furthermore, our approach is also aimed at maximizing retention from the pool of applicants while also very effectively screening out those applicants that do not meet baseline performance on critical non-trainable KSAOs.

Title:Compact, Rugged, Multiple Spectral Band Laser
Abstract:nLIGHT proposes the development of a multiple spectral band laser head that is based on a vertically stacked array of single emitter laser diodes. A key design aspect of this device is that the proposed laser head is largely based on a multi-emitter pump module that is currently under commercial development at nLIGHT. The commercial laser product, upon which the proposed system will be based, has already undergone the process development, thermal characterization, and environmental testing, thus significantly improving the development time, product development risk and likelihood of program success. At the heart of the proposal is nLIGHT’s capability of producing single emitter laser diodes from 639 to 2100 nm. nLIGHT currently produces high performance single emitter diodes that achieve the following performance at wavelengths at or near the solicitation specifications. While each device is rated for > 2 year reliability under CW, as will be shown later in the proposal by increasing the emitter stripe width and by using pulse operation it is expected that the output power could be increased by a factor of 2-4x, thus enabling the pulse requirements of the program (2-8 W) from a single laser device at 639, 80x and 1700 nm.

Title:Multi-wavelength direct diode lasers based on Wavelength Beam Combination for Navy applications
Abstract:There is a compelling need for multi-spectral direct diode lasers for defense and commercial applications. Applications include target illumination and detection, terrain/object/building mapping, construction, surveillance, industrial process control, and free-space optical communications. Existing, commercially available direct diode lasers have some of the most desirable attributes: highest efficiency, greatest compactness (small size, weight, and power or SWaP), and wavelength selectability from the UV to the mid-IR bands. The main disadvantage is poor output beam quality. TeraDiode’s technology of Wavelength Beam Combination (WBC) effectively solves the poor output beam quality problem of direct diode lasers. Using WBC technology, TeraDiode will be able to build a multi-band diode laser module that satisfies or exceeds 100% of the Navy requirements for this program. TeraDiode’s technical approach is scalable to much higher power and beam quality, up to multiple kWs of power if required for the application.
