Title:Benzoxazine Matrix Composite Bearing Materials for Arresting Gear Components
Abstract:Carrier aviation is dependent on the ability to recover aircraft expeditiously and safely aboard ship. The system that arrests the aircraft, the Arresting Gear system, utilizes slippers or bearing materials between moving components. The Arresting Gear system on Navy carrier aircraft utilizes slippers or bearing materials between moving components. These materials bear the weight of the various arresting gear components and function as the sliding medium between components to allow free movement during arrestments. The current slipper material is a cotton-fabric reinforced graphite phenolic-based composite material. A major shortcoming of this material is it’s swelling when exposed to ethylene glycol, which causes clearance issues in the operating equipment. As a result, replacement is often required outside of scheduled maintenance, which is undesirable due to the labor-intensive nature of some of these replacements. Consequently, the Navy is seeking a new slipper material that would maintain dimensional stability throughout its lifetime, and have low wear rates compared to the existing material. It is desired for the slippers to have a life of 20,000 arrestments, with no shelf life limitations. Improving the life of the slippers will result in labor savings and greater equipment availability. During the Phase I program, Composite Technology Development (CTD) will develop a new composite bearing material comprised of either glass or carbon reinforcing fibers and a benzoxazine resin chemistry in place of the current phenolic resin to replace the current cotton/phenolic composite bearing material. Nano-scale additives such as clays, silica, silicon carbide, and carbon will also be incorporated to improve the wear resistance and friction characteristics of the resulting composites.

Title:Improved Bearing Material for Aircraft Carrier Arresting Gear Components
Abstract:Current phenolic-based composites used for the slippers of the MK 7 arresting gear system have insufficient wear resistance to ensure an extended service life, and are subject to swelling when exposed to shipboard fluids. The resulting unscheduled maintenance repairs are costly, and the Navy seeks new technologies that will replace the current slipper composite material and have higher durability. Texas Research Institute Austin Inc. (TRI/Austin) proposes a novel composite material that will provide enhanced wear resistance, excellent mechanical and environmental properties, and will serve as a drop-in replacement for the current material while remaining in service for a minimum of 20,000 landings. Preliminary abrasion resistance tests show a Taber wear index of only 37 after 25,000 revolutions, and similar materials developed by TRI/Austin have been virtually unaffected by exposure to hydraulic fluid and other shipboard challenges. During Phase I, compressive, tensile, impact, fluid and environmental resistance, temperature tolerance, and tribological testing will demonstrate the resilience, wear resistance, and high lubricity of the composite material. Formulation and materials optimization will be conducted and samples will be delivered to the Navy. Prototype arresting gear components will be developed and tested in Phase II, setting the stage for rapid Phase III transition.

Title:Wear and Chemical Resistant Arresting Gear Slipper Material
Abstract:The arresting gear system on an aircraft carrier utilizes slippers and bearing materials between moving components. Presently, these bearing materials are a phenolic composite reinforced with a cotton textile and friction modified with graphite. The purpose of this proposal is to find a replacement material. The reasons for replacement of the material include: availability of the existing material, swelling from contact with ethylene glycol, wear debris damage to associated seals, and wear life.This application presents several challenges, most notably related to the wide range of pressures and velocities across the various slipper applications. There are nine slipper configurations in the system. Each has its own set of operating characteristics. The surface contact pressure varies from 10psi to 530psi. The contact speed varies from 0 to 540 in/s. The sliding distance can be up to 112 in. The sliding surface finish (Ra) varies between 16 micro-inches and 125 micro-inches. The surface may have any combination of dry, greased, ethylene glycol, and environmental contamination. Using wide spectrum wear testing as a measurement basis, a number of materials, both commercially available and novel, will be compared with the existing bearing material. An alternate, or alternates, will be selected or developed, based on wear life over the spectrum of operating conditions that simulate, as closely as feasible, the field operating conditions.

Title:Acoustic Array Simulation Environment System
Abstract:This program addresses a defined need by the NAVY for an Acoustic Array Simulation Environment System (AASES) to facilitate analysis of Time/Angle of Arrival methodologies as well as testing, validation and verification of antisubmarine warfare (ASW) systems on fixed wing (manned and unmanned) and rotary wing aircraft. This need can be addressed by deploying standard sonobuoys and actual vessels as the object to be detected and located. This method is effective but costly and labor intensive. In Phase I, a more cost effective and flexible testing and analysis system will be investigated. This will be accomplished by designing a system based around reusable sonobuoy surrogates(SSB) which receive and then transmit simulated signals that represent what a standard sonobuoy would have measured in its location from the chosen type and location of vessel in the simulation. In operation the system will receive the simulated acoustic signal for each of the SSBs and then wirelessly transmit that signal to the appropriate SSB which will then transmit the signal over a standard sonobuoy radio link. The system will consist of up to 64 SSBs each transmitting their received simulated signals for reception by any ASW receiver system. Phase II will implement prototyping.

Title:Acoustic Array Simulation Environment System
Abstract:ASW training requires an accurate simulation of both sonobuoy data content and geolocation in order to maintain peak crew proficiency. Unfortunately, existing systems can generate and emit the necessary field of 64 sonobuoy signal simulations, but without the geographic dispersion of a real sonobuoy pattern (which is an unaffordable training option and unrealistic/uncontrolled simulation scenario). Thus the crew cannot train with the direction finding and geolocation features of the ASW system. Given the physical impossibility of spoofing a TDOA DF system, Softronics instead proposes a system based on the existing SASSIE/RFSonosim sonobuoy simulators that remotes the RF transmitter portion of the RFSonosim via datalink. This breaks up the 64 simulated sonobuoy emissions emanating from a single location; any mix of single site and deployable land/sea nodes can be used, and dispersed as desired to provide ASW crews a realistic sonobuoy pattern training event. The RF nodes are small, reusable, low-cost, buoy-packaged, and fully remotely operated, with all of the sensitive acoustic scenario generation system safe on shore.

Title:Refractory Coating for Heat Resistant Portable Helipad
Abstract:Eltron Research & Development, Inc (Eltron) has developed a refractory, flexible, inorganic paint that has shown excellent performance in protecting polymers from direct heat sources. In this project, Eltron will coat portable helipad mat materials such as polyethylene and polyester as well as other high temperature polymers and lightweight materials with refractory paint. Eltron’s refractory, ceramic coating will be completely inorganic and highly refractory with a melting point of >1000?C which will improve the thermal resistance of mat materials to be able to withstand 650 ?F minimum for 20 minutes minimum. We’ve developed a series of methods to provide excellent adhesion of our coatings to a variety of substrates including polymers, ceramics, and metals. Since Eltron’s coating provides a thin, refractory layer, there should be little change in weight, density, or volume compared to uncoated mats. The refractory coating should provide no change in corrosion and weather resistance, installation, ground preparation, ground securing, or dust suppression compared to uncoated mats. The structural and thermal properties of refractory coated mat samples will be shown to be superior to uncoated samples while maintaining many of the puncture strength, tear resistance, and air permeability properties required for a portable helipad.

Title:Innovative Cost-Effective and High-Temperature Portable Helipad
Abstract:The objective of this SBIR Phase I proposal is to develop a lightweight, cost-effective, and high-temperature resistant portable helipad for future helicopters and vertical landing aircrafts. Portable helipads are critical for forward operating bases, and enable aircrafts to land in any area safely and quickly without causing the brownout. The current technology is very effective for rotary crafts, but not for other vertical take-off and landing and thrust vectored aircrafts due to thermal limitations. Frontier will propose a novel material system to allow increased temperature sustainability and provide the Navy and Marine with the advanced material technology they need to facilitate future vehicles safely where brownout conditions may arise. Feasibility of the design to meet thermal, air permeability, and mechanical requirements as well as effectively suppress dust kick up will be outlined and systematically studied. Cost, required manpower, installation, manufacturability, reliability, and maintainability will also be analyzed for various design solutions.

Title:Multi-material Helipad
Abstract:The goal of the Phase 1 effort is to demonstrate the feasibility of using a structurally flexible multi-layered insulation for increased thermal management and reduced weight for a portable helipad for austere environments compared to the current single material system. Hor gases and thrust particulates from aircraft exhaust can create extreme temperatures and thermal shock leading to premature failures in exposed materials. Carbon and basalt non- woven fabrics and felts have tremendous temperature and thermal shock resistance making it the ideal material solution for flexible high heat portable helipads. The concept has great potential to limit the heat through the thickness and to maintain the underlying ground surface to below 200 0F. The architecture of the layered stack of materials is designed to produce a tortuous thermal path through the thickness and to spread the heat applied to the top surface from the exhaust laterally within the multi-material top layer. No through seams exist in the design to allow easy thermal transport of heat to the underlying surface. The proposed helipad mat should have excellent drapeability that will allow it to conform to irregular surfaces in austere environments that are not pre-prepared for helicopter or Vertical Takeoff & Landing operational traffic.

Title:A Model-assisted Damage Diagnostics and Characterization(MoDDiaC) wireless-sensor network based Structural Health Monitoring System for Composite Roto
Abstract:Advanced composite materials, increasingly adopted for airframe structures, are susceptible to barely visible impact damage, which has the potential to lead to a catastrophic failure if not accurately monitored. Structural health monitoring (SHM) based on acousto-ultrasound method has emerged as a promising technique for monitoring the onset and progress of structural damage. Acousto-ultrasound based SHM system employs generation and propagation of stress waves through attached piezoelectric transducers giving necessary information for monitoring the health of the structure. However, these techniques are generally suitable for simple structures without any local property /thickness variations. In this SBIR program, Acellent proposes to develop an innovative model-assisted SHM system that is capable of detecting, locating and characterizing type of damage on composite rotocraft structures. The proposed system learns sensitive signal features through a physics based wave propagation simulations and utilizes the knowledge to optimize sensor network for the given structure, and integrates offline learning with the current sensor data to accurately locate the damage even for complex structure with local property/thickness variation. Prototypes of the proposed model-assisted SHM system will be developed and demonstrated under representative loading and environmental conditions. Functionality of the proposed system will be tested thouroughly for different damage types.

Title:Carbon Nanotube Sensor Thread for Structural Health Monitoring of Composites
Abstract:This project will manufacture carbon nanotube(CNT) sensor/tape for use in distributed structural health monitoring(SHM) systems that will be integrated into/onto composite materials to provide damage detection, localization, and characterization. Composite test samples with internally integrated sensors will be built and evaluated to detect/locate multiple damage modes including fiber breakage and delamination. Analytical predictions of the damage magnitude and likely progression of detected flaws over time will be made. Composites with integrated CNT sensor thread/tape will have the following advantages:• Self-Sensing- CNT piezoresistive thread can measure strain/damage, thread impedance decreases at high frequency increasing sensitivity• Increased Strength- Composite strength will increase based on CNT volume fraction• Damage Limiting- CNT thread has high strain to failure and will self-limit damage by absorbing strain energy• Improved Transport- CNT thread has high thermal and electrical conductivity in-plane• No Significant Added Weight or Size- There is almost no added mass of the sensor thread• Modest Cost- Cost for the CNT materials and composites processing is modest• Detection, Localization, and Characterization of Damage- Discerning between a crack and delamination will use a computer algorithm to map the shape of damage• Improved Composites- Can determine failure progression in composites and provide understanding how to reinforce composites

Title:Innovative Structural Health Monitoring (SHM) System Capable of Detecting, Localizing, and Characterizing Damage in Composite Aircraft Structures
Abstract:Some success has been achieved with SHM of with simplified composite aircraft structures in laboratories. However, more complex structures with thickness variations, stiffeners, bonded joints; fasteners etc have been less successful. This is becoming a very serious issue, as the new H53-K uses large amounts of composites.Texas Research Institute Austin, Inc. (TRI/Austin) has a flight proven SHM system, the Large Area Health Monitoring Processor (LAHMP). It is a complete, miniaturized, acoustic emission system with built in, patented algorithms to determine fitness for service and damage location based on AE data. These algorithms were developed from data collected during laboratory and full scale fatigue, and flight proven, using real, fixed wing military aircraft composite structures. LAHMP has passed MIL-STD’s 810, 461 and 704. The research team of TRI/Austin, Sikorsky and University of South Carolina proposes NAVAIR fund development of an even smaller, lighter, more rugged version of LAHMP for helicopter service. This system will use Acoustic Emission (AE) sensors to passively, continuously monitor composite structure health. The proposed work includes expanding prior work by our research team on 1) ballistic damage detection and assessment and 2) defect typing. All work will be performed on real composite structures from military aircraft.

Title:Development of New Processes for the Refurbishment of Infrared Search and Track (IRST) Germanium (Ge) Domes
Abstract:After extensive exposure to adverse environments such as sandstorms, rain, and fog, germanium (Ge) Infrared Search and Track (IRST) domes develop pits and surface damage, which accumulates over time eventually reducing the average transmission to below acceptable limits. New domes are quite costly since they are produced from single-crystal germanium (Ge) with very sophisticated inner and outer surface coatings. A process is needed that is capable of restoring the damaged domes to a state or condition that meet all of the imaging and environmental requirements of the original dome. Surmet has developed a portfolio of technologies that will be drawn upon to establish such a refurbishment process. The first step is to remove the damaged surface layer, replace it with a thick, durable and machinable coating layer, refigure the surface of the coated dome and then apply a durable anti-reflection (DAR) coating to provide abrasion resistance and enhance transmission. In addition to yielding a compliant dome, the refurbishment process will also improve the dome’s durability.

Title:High Efficiency 808 nm Laser Pump Diode Arrays with Excellent Beam Quality
Abstract:As part of an effort funded by HEL-JTO, we recently demonstrated advanced quantum well diode laser designs with enhanced confinement operating at 1500 nm that substantially advanced the state-of-the-art with regard to efficiency, high operating temperature and beam quality. Similar enhanced confinement designs will be implemented at 808 nm to greatly improve both electrical-to-optical efficiency and fiber-coupling efficiency. Moreover, by incorporating monolithic internal diffraction gratings in these lasers, linewidths and wavelength tolerances can be reduced by roughly a factor of 4 compared to standard pump diodes without incurring the cost and complication of external volume bragg grating stabilizers.

Title:High Efficiency 808-nm VCSEL Arrays with Excellent Beam Quality
Abstract:Today’s high energy Q-switched Nd:YAG lasers are often pumped by stacks of multiple edge-emitting diode laser bars since the vertical-cavity surface-emitting laser (VCSEL) traditionally have been lower in efficiency. In this effort we are proposing a novel VCSEL design which overcomes the efficiency bottleneck in conventional VCSEL while preserving its beneficial attributes such as uniform beam in the far-field, higher brightness, narrow spectral width, less sensitivity to thermal drift in center wavelength and lower cost of manufacturing. Under the proposed program, nLight will develop and demonstrate a high power, high efficiency and high beam quality VCSEL array near 808 nm, with efficiency compared to the state-of-the-art edge-emitting diode laser bars. nLight will achieve this by leveraging its industry-leading high efficiency 808-nm epitaxy design, and incorporating a cascaded bipolar VCSEL design. The end goal of the program is to achieve > 60% wallplug efficiency and >1 kW QCW optical power in a 0.5 cm2 high power VCSEL array, with a spectral width less than 1 nm and a temperature coefficient of lower than 0.1 nm/°C.

Title:High Efficiency 808 nm Laser Pump Diode Arrays with Excellent Beam Quality
Abstract:The Navy is interested in developing high power and high operation efficiency pumps at 808nm for multiple Navy applications. VCSEL technology offers an excellent choice for the development of such laser pumps. Princeton Optronics has developed the technology of high power VCSEL arrays delivering hundreds of watts of power from small chips with >55% efficiency at 976nm. We would use improvements of those techniques as well as some new approaches to 808nm VCSELs to develop very high efficiency high power pumps. We propose an approach in which we would use improved quantum wells and other improvements on how the quantum wells are arranged in the cavity to dramatically improve the efficiencies of the VCSELs at 808nm. In phase I, we would demonstrate the feasibility of the approach and in phase II we would deliver >100W arrays with very high efficiencies as required in the solicitation.

Title:Deep Vector Sensor System
Abstract:Applied Physical Sciences and the Navmar Applied Sciences propose to adapt existing vector sensor and sonobuoy technology within their respective areas of expertise to develop a preliminary design for a passive deep water directional sonobuoy. The Phase I Base is centered on tasks pertaining to vector sensor design with emphasis on achieving the stringent noise floor criteria in an A-Size sonobuoy form factor. Other critical tasks include those concerning sonobuoy design which focuses on aspects related to packaging, deployment, hydro-mechanical self-noise, and telemetry. A small task will be conducted to obtain preliminary system level performance predictions of the vector sensor in an operationally significant environment. During the Phase I Option prototype designs for the pressure hydrophone and pressure-gradient hydrophone will be fabricated and tested for model validation purposes. The same type of test and evaluation approach will be employed to assess the fidelity of the hardwire telemetry link which routes the data from the sensor to a surface float.

Abstract:The Phase I program is directed at defining a buoy configuration that will capture the improved signal-to-noise ratios of surface or near-surface targets-of-interest when the acoustic sensor is located below the critical depth and as close to the ocean bottom as possible, capitalizing on the Reliable Acoustic Path. The overall buoy configuration options include a free-floating buoy and a buoy with an on-the-bottom sensor subsystem. In addition, the Phase I effort will include optimizing each subsystem and establishing a reliable packaging and deployment approach. Critical subsystems being optimized include the vector acoustic sensor and the subsurface-to-surface data link.

Title:Deep Vector Sensor System
Abstract:The US Navy has a requirement for a Reliable Acoustic Path A-sized sonobuoy system. The major challenge is to reduce sensor electronic noise to exploit the environment. Additionally, A-size introduces numerous technical challenges for flow and vertical motion induced noise mitigation, for data telemetry, and for packaging. Progeny Systems Corporation teamed with UnderSea Sensor Systems, Inc. proposes to develop an innovative Deep Vector Sensor sonobuoy based on single crystal vector sensor technology. Single crystal sensing elements offers a wide frequency range in a compact size with low power consumption, and our low- noise analog signal conditioning and compensation microcircuitry can meet the noise requirements. Our sonobuoy concept features a decoupled drifting sensor module with passive buoyancy compensation that deploys after descent to near the ocean bottom in up to 6km water; up to a one hour deployment sequence. Precision wound fiber optic cable provides telemetry, with suspension to buffer vertical wave-induced motion. A modified upper electronics assembly serves as communications gateway to the aircraft.Our Phase I effort will design and demonstrate feasibility for the vector sensor, design and model the drifting sensor module, and develop the high level buoy design. Phase I option will fabricate and test the sensor.

Title:Fiber Optic Vector Sensor Sonobuoy System
Abstract:VIP Sensors proposes to develop a very low noise, highly sensitive Fiber Optic Vector Sensor (FOVS) System packaged in a size - A sonobuoy. The FOVS includes a triaxial optical accelerometer, an omnidirectional optical hydrophone and an optical compass. Only a pair of single mode optic fibers interconnects the fully passive vector sensor located below sea level to the sonobuoy’s Surface Electronic System. The FOVS measures the amplitude and direction of sound wave and provides its spatial orientation regarding the magnetic north and its pitch relative to the horizon. All the sensors are Extrinsic Fabry-Perot Fiber Optic MEMS devices built with spectrally selective micro-mirrors designed to be sensitive only to one particular measurand: acceleration or pressure or to the earth magnetic field. Each the sensors operate at a unique optical wavelength range within the C and L telecommunication bands. The FOVS is configured as two sensor segments in parallel, separated by an optical time delay, one segment has three accelerometers and a hydrophone, the other has three magnetic sensors that make up the compass. The Interrogation Module separates the signal spectrum of the sensors in a given segment, in a Wave Division Multiplexing fashion; and time multiplexes the sensor segments.

Title:Improved Pulse Power and Thermal Management Capabilities for Aircraft Applications
Abstract:Next generation aircraft systems will include weapons, sensors and actuators requiring large amplitude pulse power capability which will exceed the continuous power delivery capacity of most aircraft. Compact, lightweight and efficient power conversion and thermal management systems are required to provide a suitable interface between the aircraft power supply and these pulse power loads. We will develop a high density, high efficiency power conversion and thermal management system to meet these needs. Our approach uses an efficient front end conversion method which is compatible with either 115 VAC or 270 VDC aircraft electrical supplies, electrical energy storage for high power pulse capability, programmable pulse control, and an innovative thermal management system which minimizes size and weight for aircraft applications. During Phase I we will define our technical approach and analytically quantify performance expectations and prepare plans for Phase II demonstrations. During Phase II we will fabricate and evaluate a subscale prototype to show level of performance compared to stated goals.

Title:High Power Density, High Efficiency, Scalable Pulse Power Delivery System
Abstract:With the advent of pulse energy weapons, the transient characteristics of military aircraft power systems is changing. These new loads require power supplies that shield the pulse transient from the electrical distribution system, while also being highly efficient, power dense, and reliable. Mainstream proposes a lightweight, modular, hybrid pulse energy delivery system that is scalable to applications greater than 150 kW. The proposed solution will reduce the total system volume by 50%, 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. Mainstream will also fabricate a small- scale prototype incorporating energy storage elements and the associated power electronic interface, experimentally verifying pulse power operation. In Phase II, Mainstream will demonstrate a full-scale prototype on a simulated aircraft power system. Mainstream’s proposed technology will not only improve the reliability and power density of military aircraft pulse power supplies, but can also satisfy commercial power supply goals.

Title:Robust Power Conversion/Conditioning Technologies for High Power Aircraft Applications
Abstract:High power pulse weapons have been proposed for decades. Prototype lasers, for example, have had some success in destroying surface and airborne targets. High power, high efficiency laser diodes are now available to pump the lasers but they still need large amounts of energy storage. A convenient way to utilize energy dense aircraft fuel is to tap into the existing electrical generation and distribution system. But the instantaneous power levels needed for this type of weapon is beyond their capability. The objective of the solicitation is the development of innovative high density, high efficiency power conversion and conditioning technologies supporting high power, low duty cycle applications. The ultimate purpose is to buffer the aircraft’s generation and distribution system from the effects of high power pulse loads. RCT proposes to use an innovative architecture that will draw constant power from the generator while simultaneously firing the weapon and storing electrical energy, in pulse power batteries and/or super capacitors, for the next shot. RCT plans to use SiC power modules at high junction temperatures with only natural convection thus eliminating the complexity of active cooling. These power switches can run at high frequencies, reducing the size of EMI filter components.

Abstract:Objective of the proposed research effort is to design, build and test an experimental AJ antenna for GPS receiver and Iridium transceiver functionality and to develop novel signal processing techniques without compromising the AJ suppression capability of either of the two systems. The AJ antenna will have at least four elements and will be approximately four inch in diameter. The individual antenna elements will be designed to receive M-coded GPS signals in L1 and L2 band as well as receive and transmit Iridium communication system signals simultaneously. Since the transmitted signal is much stronger than the received signals, the antenna must provide good isolation to enable the simultaneous reception of weak navigation and communication signals and transmission of strong communication signal. In this project, Applied EM along with its team members will develop a new signal processing algorithm for the antenna electronics (AE) such that the signal processing capability of a given receiver (GPS or Iridium) are not compromised by the presence of the other signals. Size, weight and Power (SWAP) will be considered in the development of antenna and antenna electronics so that the same antenna system can be used for airborne as well as undersea vehicles.

Title:Iridium/GPS Anti-Jam Antenna System (iGAAS)
Abstract:GPS is extremely vulnerable to signal interference, both unintentional and deliberate. Military navigation systems for air and sea vehicles require reliable GPS performance and the use of Iridium signals to provide an alternate robust worldwide navigation and communications capability. Some type of jamming signal mitigation technique is needed beyond conventional filter methods since these interference signals are in the GPS/Iridium bands and therefore cannot be removed with traditional in-band filtering. Consequently, a cancellation method that preserves the GPS/Iridium signals while eliminating the undesired interference is needed. Antenna nulling methods are a common solution for mitigating jammer signals from GPS, however many existing air and sea vehicles have limited space and power requirements that do not allow for traditional antenna nulling/beam-steering anti-jam solutions that require large antenna arrays and antenna electronics of considerable power and size. Mayflower proposes to leverage its SAS AJ technology with added Iridium capabilities and integrate the antenna nulling electronics into a 4-inch diameter multi-element array with Iridium support. The proposed Mayflower iGAAS system will be a common solution for air and sea vehicles that will provide simultaneous GPS reception and Iridium transmit/receive capability, as well as simultaneous nulling protection of the GPS and Iridium bands.

Title:Ocean Surface Transceiver Free Space Optical Communication System
Abstract:Communication from ocean-surface sonobuoys to airborne platforms is critical to Anti- Submarine Warfare (ASW) operations. Existing Radio-Frequency (RF) solutions encounter several challenges which Free-Space Optical (FSO) systems solve. FSO systems for sonobuoy applications have unique challenges that proper system design can overcome. Verdant Networks is proposing an asymmetric system design that meets key performance, size, power, and cost requirements with several advantages. Design and development risk is minimized by leveraging existing Pointing Acquisition, and Tracking (PAT), optical, and modulation technology. Projected system performance will be experimentally validated by utilizing a proven test bed during the Phase 1 Option. By the end of Phase 1 a low-risk, experimentally verified design will be available to prototype and demonstrate in Phase 2.

Title:Gimbal-Free Wavelength-Division-Multiplexing Free Space Optical Communication (WDMFSO) for Ocean Surface Transceivers
Abstract:Lasercom, namely, free-space optical (FSO) communication, has many advantages over the traditional RF communication channels widely used in military communications. Some notable advantages of lasercom are no need for licensing for frequency allocation, immunity to radio frequency interference, and low probability of interception and detection. The biggest disadvantage of lasercom, however, is its requirement of point-to-point and line-of-the-sight configuration between optical transceivers. Pointing and tracking via gimbal systems as well as other mechanical tuning of orientation and pointing are often required. We propose an optical WDMFSO system with mature WDM system architecture, resulting in (i) NO gimbal, and (ii) NO pointing and tracking.During Phase I, we will design, fabricate and characterize infrared photo-detectors for application in the WDMFSO system. We will also experimentally prove the concept of the WDMFSO system at reduced distance scales within the laboratory. In Phase II, we will further optimize the photo-detector technology based on the feedback from Phase 1 experiments, and fully prototype and develop a complete WDMFSO system for field testing. During Phase III, we will manufacture and market the WDMFSO system as well as for our commercial medical device products.

Title:Enhancing Situational Awareness to Counter Swarming and Other Nonlinear, Dispersed Tactics Against Naval Surface Forces
Abstract:Toyon proposes to research and develop algorithms and software that provide enhanced situational awareness to watchstanders of naval vessels. These algorithms will employ advanced data fusion and pattern recognition technologies with the primary objective of identification and early warning of hostile swarming or other nonlinear, dispersed tactics in a 360-degree field-of-regard around the vessel. Fusion algorithms will provide persistent feature-aided tracking, target classification, and target fingerprinting to monitor and characterize each surface vessel in the surveillance region. This set of tracks will supply the data from which group behavioral features will be extracted for subsets of tracks hypothesized to form a coordinated “swarm group”. These features will then feed a threat detection algorithm that will detect abnormal behaviors that are observed, such as coordinated actions by a group of targets. In Phase I, Toyon will perform a feasibility study of the proposed solution by developing and extending component data fusion algorithms, designing the group behavioral feature models, and evaluating anomaly detection performance to meet the specified technical objectives of the project.

Title:Automated Antenna CAD for Installed Performance Assessment and Optimization
Abstract:Our team proposes to expand the capabilities of an existing software tool so that is capable of producing CAD models and associated configuration information for representative antenna designs given the type of information that can be found on a vendor’s specification sheet. The user will select an antenna type from a database of antennas and specify design objectives. An underlying computational engine will be used as the basis for an optimization engine that creates designs to meet the objectives specified. The approach for creating representative designs for antennas will be demonstrated using realistic example antennas. Performance metrics will be developed to assess the accuracy of the approach. A list of common antennas employed on NAVAIR aircraft will be compiled and mapped to existing antenna types supported by Antenna Magus. If there is a need for additional antenna models, they will be developed. A study will be conducted to assess the accuracy of using representative designs versus the actual antenna design for installed antenna performance analyses. The proposed tool will also include a capability for searching the antenna database according to specific applications. This database will also allow the user to save, organize and share representative designs developed by NAVAIR.

Abstract:To address the Navy’s need for an antenna design tool that will rapidly produce CAD models of commercial off-the-shelf (COTS) aircraft antennas, Physical Optics Corporation (POC) proposes to develop a new Inverse Neural-Network-based Automated Antenna CAD Tool (INNCAD). The innovation in algorithms based on trained knowledge-based inverse neural networks (INN) and an innovative antenna knowledge database (ADB) produce rapid automated design CAD models of COTS aircraft antennas that are ready to use in the Navy’s CEM simulation tools to evaluate performance when installed. This device offers a methodology that uses COTS antenna performance and physical data to yield complete antenna designs and their physical descriptions, directly addressing Navy requirements. In Phase I, POC will develop a complete system architecture with details of the graphical user interface (GUI) and demonstrate the ability to produce a valid antenna design from top-level specifications for at least two types of antennas. In Phase II, POC will develop INNCAD into a complete engineering tool, which will include a GUI, interface to the Navy’s CEM codes, and a complete version of the ADB and INN to design a comprehensive set of aircraft antennas.

Title:A Miniaturized SERS Based Sensor Technology for detecting toxic contaminants in oxygen from aircraft On-Board Oxygen Generating Systems (OBOGS)
Abstract:Aircraft equipped with On-Board Oxygen Generating Systems (OBOGS) selectively filter nitrogen and other gaseous contaminants in air from the aircraft's engine to provide the aircrew with an oxygen enriched breathing gas. Under suboptimal operating conditions, toxic byproducts can breach the OBOGS and enter the aircrew's oxygen supply. Current contaminant sensor technologies tend to lack the response time, reliability, specificity, and robustness needed for military aircraft. Thus, there is a need for a compact, highly reliable/specific sensor for multiple toxic contaminants to monitor oxygen produced by aircraft OBOGS. Ideally, such sensors would be: detect (as a minimum) CO, CO2, NOx, and aliphatic/aromatic hydrocarbons; compact and lightweight; not drift over time; and include a visual alarm indicator, and an electronic output signal that can interface with an aircraft's caution and warning system. The objective of the proposed work is to develop such a sensing module, based on the combination of a miniaturized surface enhanced Raman scattering (SERS) spectroscopy concept and existing low-power wireless sensor network hardware. This Phase I effort will include: working with OEMs to define requirements; analyses; evaluation of the sensing module hardware/packaging design concepts; and construction and proof of principle demonstration of first generation hardware.

Title:Carbon Monoxide Detector For Aviation Oxygen Systems
Abstract:Aircraft On-Board Oxygen Generating System (OBOGS) selectively filters compressed air from the aircraft's engine to remove nitrogen and other gaseous contaminants to provide the aircrew with an oxygen enriched breathing gas. During shipboard operations, Navy aircraft are particularly vulnerable to excessive levels of toxic byproducts from ingesting the jet exhaust from other aircraft. Under suboptimal operating conditions, toxic byproducts can breach the OBOGS and enter the aircrew's oxygen supply. NAVAIR is developing an oxidizing catalyst to eliminate these toxins, but a sensor is needed to determine when the catalyst may be losing effectiveness. Vista Photonics proposes development of a compact, flexible and rugged multi-gas sensor compatible with the OBOGS challenging environment. The sensor will be capable of providing a visual alarm indicator, as well as electronic output signal to interface with the aircraft's caution and warning system, when concentration of a toxic compound exceeds the specified threshold level. Phase I study will prove the feasibility of the proposed technology and outline the concept of the Phase II prototype instrument.

Title:High Efficiency SIGINT Collection
Abstract:Our proposal specifically addresses the stated requirements of the solicitation; we will develop and deploy tools and methods for efficiently collecting, analyzing and classifying narrowband signals within a wide radio-frequency spectrum. The number of potential hostile waveforms in the RF environment will continue to increase with an essentially random distribution. However, at any given time, the overall spectrum population is sparse. Any receiver on an airborne platform attempting to perform SIGNAL Intelligence (SIGINT), or Communications Intelligence (COMINT) currently relies on brute-force Nyquist sampling of wide swaths of spectrum and using storage and processing-intensive methods. The approach we propose aims to reduce the processing, storage, and transmission burden on the SIGINT system by using innovative sampling techniques and algorithms as well as making better choices about where in the spectrum to focus the search for signals of interest. The proposed Edaptive Heiste solution builds on previous Edaptive Computing, Inc (ECI) knowledge and technology – itself innovative – to provide the user with near real-time intelligence of the various communication signals in the vicinity. The proposed solution will add to the situational awareness of the war-fighter and do so in a manner that does not demand vast hardware and processing resources.

Title:High Efficiency SIGINT Collection
Abstract:Signals intelligence systems use the established Shannon-Nyquist approach of signal acquisition, setting a sampling requirement based on data rate. This sampling approach is generating operationally impractical amounts of data, most of which goes unused or arrives late. The conventional rate of data-to-information (DTI) conversion is low, and there exists high demand for a solution. A new approach to signal sampling achieves efficient DTI conversion. Our approach exploits mathematical sparsity to produce high accuracy information sensing (ISENSE) with reduced sampling rates. This technique employs the relatively new science of compressive sensing (CS) and compressive processing (CP), which extract information with fewer samples compared than when sampling at the Nyquist rate. As an extension to known CS techniques, ISENSE continuously validates sparsity patterns, taking CS from theory to a deployable technology. We apply ISENSE to the intercept, detection, characterization, classification and identification of emitters. We will illustrate, by qualitative and quantitative measures, how the ISENSE capability maintains DTI accuracy and detection probabilities despite reduced sampling rates, thus improving Naval airborne SIGINT data collection, storage, transport, and processing efficiency.

Title:High Efficiency SIGINT Collection
Abstract:U.S. intelligence, reconnaissance, and surveillance (ISR) platforms employ SIGINT sensors for target platform detection, identification and location. Many receivers are narrowband and are scanned over the RF spectrum (e.g., 2-18 GHz) in search of RF emitters of interest. With the rapid proliferation of RF technology, the signal spectrum has become complex and congested placing a burden on the SIGINT receiver to keep up with its surveillance and data processing requirements. However, the receiver must maintain a high probability of intercept for critical emitters. The objective of this SBIR topic is to develop methods for efficient SIGINT receiver data collection and processing. This proposed program will develop a mathematical optimization algorithm that will generate a receiver frequency band scan schedule that maximizes the receiver's resource usage. The algorithm is envisioned to enable the mission planner to prioritize the scan schedule for specific emitter signal intercept. The solution will be applicable to fielded receiver systems such as the ALQ-217, and should not require any hardware modifications. A software prototype that implements the optimization algorithm will be developed, and simulation results will be prepared that demonstrate the advantages of an optimized scan schedule compare to a baseline schedule.

Title:In-Air Sound Sources for Anti-Submarine Warfare
Abstract:With the continual reduction in radiated acoustic levels of submarines around the world, active sonar has become essential in all aspects of Anti-Submarine Warfare (ASW) operations. Further, bistatic and multistatic active sonar systems increase the spatial diversity of detection systems and afford improvements over monostatic systems in performance against potential threat submarines. Source development has been a focus, but the size and complexity of source designs, particularly at the lower frequencies necessary for longer range acoustic propagation, makes this aspect of the active sonar system technically challenging. This is especially true for air-deployable multistatic active sonar systems. An airborne acoustic source, combined with a field of air-deployed acoustic sensors in the water, has the potential to enable a wide area, active, search capability that limits the ability of submerged threats to effectively predict source location and reduce their own vulnerability to detection. The purpose of this SBIR proposal is to:• Assess the feasibility of airborne acoustic sources for active sonar• Develop source concepts that provide the ensonification levels and source waveforms necessary for submerged threat detection, and• Plan at-sea experiments to validate the concepts for development.

Title:Airborne source multistatics
Abstract:HLS Research has participated in several research initiatives for various sponsors pursuing innovative concepts that strive to exploit “ambient” noise sources to illuminate targets and environment features in the underwater acoustic waveguide. This theme has engaged researchers in many fields, such as correlating random seismic noise to image the Earth, correlating surface generated ocean noise to image the seabed, and similar efforts in the EM spectrum where the term “passive radar” has been coined. In this effort, HLS Research will adapt the integrated modeling and signal processing technology developed for these related applications to exploit the advantages provided by using an aircraft already on station to prosecute an ASW mission as an acoustic source. The challenges presented by this concept include: a direct blast that is conceptually always on (requiring capable interference cancellation), a source waveform that may have both narrowband and broadband components but for which no exact replica may be available (and thus has to be recovered from the multiple and interfering arrivals along paths from the aircraft through the rough and moving ocean surface), and relatively extreme source motion as aircraft speeds far exceed typical platform speeds underwater (suggesting wideband Doppler compensation will be an important component).

In addition SSC will conduct a tradeoff study concerning available source noise generation alternatives for the infrasonic frequency source generation mechanism which will be will be experimentally verified (Phase I Option) to fully explore the feasibility of the evanescent (lateral wave) excitation path. Finally, SSC will assess the advantage of using ship based towed arrays as receivers for these airborne sources.

Abstract:The research objective of this proposal is to perform computational alloy development to enhance the Ti-6Al-4V chemistry for direct digital manufacturing (DDM). The new alloy will be designed to attain the following attributes: (1) isotropic behavior with mechanical properties on par with the upper bins of Cast+HIP Ti-6Al-4V; (2) ability to deposit builds within a window of processing conditions commonly available in the current generation of DDM equipment; (3) ability to qualify the material as per the framework described in the industry standards, AMS4999A or ASTM F42; (4) raw material cost comparable to the Ti- 6Al-4V additive material. The new alloy chemistry will be targeted to attain the following: (1) refinement of grain size; (2) reduced propensity to form porosity; and (3) promote fracture toughness. Its processing parameters will be targeted to maximize basketweave microstructure throughout the deposit and to eliminate the need for post process HIP treatment. The new chemistry will be determined using analytical trial and error, which will be supported by limited deposition testing. Analytical iterations will be performed using thermodynamic modeling and process simulation. The depositions, microstructure evaluation and mechanical testing will be performed for a limited number of chemistry variations and the data will be used for the calibration of simulation input, its predictions and the demonstration of feasibility.

Title:ARCSIN: Adaptive Real-time Control Station INterfaces
Abstract:Future operations will increasingly utilize unmanned vehicles (UxVs) to accomplish complex missions. UxV’s have the potential to dramatically improve real-time situation awareness and increase mission success. Current advancements in performance and capabilities of UxVs and automated mission planning systems are enabling a shift from direct teleoperation towards supervisory roles. With this shift, there is a need to develop intelligent human- computer interface and interaction techniques that enable a single operator to remain cognizant of the current mission status and rapidly understand the state and activities of multiple vehicles in a multi-domain environment. Operators need intuitive, simple visualizations that enable quick and effective mission-level decisions, particularly during autonomous re-planning and re-tasking that require human assistance or intervention. To develop: (1) robust human-computer interactions for facilitating coordination by human operators and automated planning technologies for rapid course of action analysis; and (2) innovative visualizations and interfaces that adapt to changing needs based on context, Aptima and our partners propose to develop Adaptive Real-time Control Station INterfaces (ARCSIN). ARCSIN provides intuitive interfaces to operators that enable them to make real- time decisions in the face of unforeseen events, visualize recommended courses of action from mission planning systems, and reduce information overload to a manageable level.

Title:Advanced Mission Display and Planning Tools (AMPT)
Abstract:Intuitive mission display visualization and planning capabilities are needed to enhance operator situation awareness when supervising teams of unmanned vehicles. To address this need, we will design and demonstrate Advanced Mission Display and Planning Tools (AMPT) to reduce the workload of re-planning and re-tasking teams of heterogeneous vehicles. These decision-support interfaces will use simple visual structures to convey complex behavior-shaping events that operators can intuitively perceive and efficiently respond to, thereby resulting in enhanced insight and direction of the planning tools. First, we will expand prior analyses of unmanned operations to characterize operators’ need for observability and directability of automated planning tools. Second, we leverage this analysis to design: (1) ecological mission displays that enhance operator awareness of the relative efficacy of automated plans with respect to mission goals; and (2) advanced planning algorithms that incorporate both hard and soft constraints during mission re-planning and re-tasking. Finally, we will extend existing in-house planning algorithms, display tools, and simulation environments to rapidly prototype of AMPT mission display visualizations and planning component algorithms. We will use these prototypes to demonstrate and evaluate our approaches and to deeply explore the complexities of rapid re-planning and re-tasking of unmanned vehicles across complex domains.

Abstract:As deployed UxVs and the range of their applications continue to increase, the responsibility of the UxV operator has likewise shifted to encompass simultaneous control of an aggregate of multiple vehicles from multiple warfare domains. In this new aggregated paradigm, replanning, retasking, and reassignment must be supported by solutions that enable a single operator to maintain awareness of the overall tactical situation as well as status and threats associated with individual UxVs. CHI Systems and its partner, Lockheed Martin, are pleased to propose Situational Awareness with Layered Visualizations for Operators of Unmanned System Aggregates (SALVO-USA). The SALVO-USA effort will involve principled identification of mission-oriented requirements for situational awareness, associated user interface and interaction needs and relevant technologies, and analysis of the replanning process including specification of replanning triggers and evaluation of replanning technologies. SALVO-USA will provide operators with an intuitive interface consisting of multiple coordinated layers of information for individual vehicles and the battlespace as a whole. These new approaches will empower the individual operator in a multi-vehicle multi- domain environment.

Title:Autonomous Decision Support for Unmanned Vehicle Control in a Multi-vehicle, Multi-domain Environment
Abstract:SoarTech will research technologies to address a fundamental problem in current unmanned vehicle operations – reduction in the amount of operator attention required to control a team of unmanned vehicles (UVs). We call our approach Lucid, and the Lucid system will monitor the mission and behavior of a team of heterogeneous UVs and1. automate the presentation of salient information to the user2. detect and project important events and alert the user to them,3. provide context-relevant, high-level inputs, making some actions as simple as one click, and4. assess user C2 effectiveness, helping to automate task distribution based on context.Lucid will enable supervisory control – allowing operators to spend less time interacting with the system and more time doing other important tasks. To achieve these results Lucid will implement computational situation awareness (CSA), and use it as a basis for intelligent UI control, decision support, and high-level command inputs. The core concepts behind Lucid were prototyped and tested in the MAGIC International Robot Competition where SoarTech teamed with the University of Michigan to win in 2010. Lucid will build on that ground-breaking work by incorporating the naval domain, CSA, C2 effectiveness estimation, and high level command into this framework.

Title:Bondline Integrity Monitoring and Assessment (BIMA) System
Abstract:The use of adhesive bonding has led to the development of novel aircraft components with and allows for the integration of different materials (composite-to-composite, composite-to- metal, skin-to-honeycomb, etc.). However, manufacturing flaws or in-service damage may degrade such joints. An issue with the use of adhesive-bonded structures in the aircraft industry is the lack of an acceptable non-destructive inspection (NDI) technique, which is part of the reason why adhesively bonded primary structures are also fastened with mechanical fasteners. Using built-in sensors for structural health monitoring (SHM) can help overcome these inspection difficulties, and can allow monitoring of the bondline during manufacturing and throughout the structures’ life – from cradle to grave. Acellent Technologies proposes to develop an on-board integrated system for detection of manufacturing and usage related damage to bonded joints in aircraft. The objective of the program is to provide the Navy with a Bondline Integrity Monitoring and Assessment (BIMA) System for detection and quantification of degradation of the bondline in aircraft structures. This information can then be transferred to prognostic models to provide predictions of remaining strength and life, thereby facilitating the development of maintenance strategies to mitigate the effects of the degradation on the aircraft safety and reliability.

Title:Guided Wave-Based Bondline Integrity Monitoring
Abstract:The implementation of structural health monitoring (SHM) into aerospace applications has been hindered by component quantity, including sensors, cables, and acquisition/computation units, as well as data quality. Particularly for large-area applications such ship hulls, complexity of the implied system infrastructure can be impractical, and data effected by attenuation and EMI-pickup along analog cables. The payoff of reliable SHM would be the ability to detect/characterize in-situ damage for condition-based maintenance, thereby greatly reducing overall life-cycle costs. Metis Design Corporation (MDC) has demonstrated point-of-measurement datalogging and digital sensor-busing during prior Phase II SBIRs, which minimizes SHM infrastructure and EMI susceptibility. During the proposed SBIR, MDC will further exploit this low-mass, long-range, scalable SHM architecture to satisfy Navy requirements for damage detection and characterization for bonded composite joints. Since the MDC SHM hardware is already quite mature, much of the Phase I effort will aim to customize piezoelectric sensors and diagnostic algorithms to best meet Navy requirements. MDC will evaluate the effectiveness of various types and configurations of piezo-sensor materials, perform sensor placement optimization, and develop customized algorithms for this guided wave based system. Finally, MDC will collaborate with Northrop Grumman to demonstrate the selected configuration using platform-relevant materials, and assess the performance.

Title:A Low-Cost, Hybrid Acoustic-Ultrasonic Technique for In-situ Bondline Condition Monitoring
Abstract:To address the US Navy's need for an innovative nondestructive evaluation (NDE) and structural health monitoring (SHM) technique for in-situ monitoring of bondline integrity for composite structures, X-wave Innovations, Inc. (XII) and Drexel University (DU) propose a low-cost, hybrid acoustic-ultrasonic technique (HAUT). The enabling NDE/SHM technique will allow the in-situ monitoring of the integrity of bondline, including composite to composite bonding and composite to metal bonding, from production to operation. For the Phase I program, XII will focus on prototyping a system and demonstrate the feasibility of the proposed HAUT technique. By the end of Phase I, we will show a working version of the HAUT prototype and have its performance evaluated. For the Phase II program, XII will refine the prototype system design and development with improved hardware and software. At the end of Phase II, we will deliver a final HAUT prototype to the Navy for further evaluation. For the Phase III program, XII will focus on collaborating with our commercial partners to improve the HAUT technology and package it into to a turnkey commercially-available system.

Title:Innovative Method for Wirelessly Powering RFID Tags Located on Rotorcraft
Abstract:Benz Airborne Systems is pleased to provide a comprehensive plan for integrating RF power charging/re-charging technologies with the long range read capabilities of semi-passive RFID. Several methods for RF power transmission have been considered and are summarized in this proposal. Our research will be on antenna performance at RFID-scale tag sizes. The resulting tags must be compatible with components in complex metallic aerospace applications. Dual/independent antennas should be avoided given size constraints, even if lower or high frequency charging schemes are contemplated. Benz has expertise in these areas including extensive full scale helicopter evaluations of RFID technology by its principal investigator. In addition to the fundamental problem of antenna design and performance, the end parts tracking application requires careful consideration to the full set of the systems’ physical and operational requirements. To provide a viable transition path for the tag technology, Benz has partnered with leading RFID ASIC supplier TEGO, who will fabricate breadboard hardware to our specifications, and ultimately a tag meeting Navy parts tracking and maintenance requirements. Consideration will be given to the development of flexible and/or “embedded” tags using MesoScribe’s Direct Write technology. Finally, the tag design will be compatible with DOD UID part marking initiatives.

Title:Innovative Method for Wirelessly Powering RFID Tags Located on Rotorcraft
Abstract:TDA’s research during this SBIR will incorporate the two main types of RFID technology: passive and active RFID systems. During previous research, TDA has shown that passive systems present challenges with respect to effective read range, as well as performance in a metal-rich environment. However, TDA believes that the performance of these systems can be enhanced via beam forming, impedance matching, and back scatter boosting techniques, as well as tag placement optimization. Similarly, TDA has shown that implementation of active tag systems is hindered by large tag form factors as well as undesirable battery maintenance requirements. TDA intends to research alternative means of powering these active tags, such as wireless power transmission. In addition, a major goal of this research will be to design and develop an ultra-low energy, solar powered active tag. By pursuing parallel lines of research in both active and passive technologies, TDA will be able to develop and recommend a complete and optimized system for the unique application of rotorcraft component tracking and sensing.

Title:CROSSED FIELD AMPLIFIER TRANSMITTER
Abstract:An update of MIL-STD-464 and MIL-HDBK-235 has lowered the Peak E-field and raised the average E-field requirements for susceptibility testing of aircraft. The equipment presently used for testing was not designed to cover both peak and average power to this extent. While it might be possible to achieve coverage by adding multiple devices, it would be more convenient and economical to achieve coverage with a single device at each frequency range. H6 Systems proposes to develop a multi-tube transmitter that is optimized for susceptibility testing and meets power requirements in a particular frequency range. Such a system would be desirable for use at government test centers such as Dahlgren, Redstone, Patuxent River and White Sands.

Title:High Powered RF Sources
Abstract:It is desirable for the standard Intersystem EMC electromagnetic environments that aircraft must operate in and demonstrate survivability of prior to production and deployment to be a single environment that provides both peak and average field level tests at the same time (instead of splitting the standard RF environment into a peak and an average field level test) just like the aircraft would see when deployed. We propose to develop under this SBIR a device and system that shall meet both the peak and average E-field levels at each of the four standard environments given within the MIL-STD-464 and MIL-HDBK-235 capable of generating a peak of 100 Kilowatts and average field of 1000 Watts. With our proposed approach, the extremely high peak power is still produced while at the same time the desired average power is also produced by a single device. The device and associated system shall also provide an illumination area of at least two foot by two foot on target at not less than ten feet separation distance. In addition, the proposed device approach minimizes the power supply requirement to be lower than for any other types of equivalent vacuum electronics devices including traveling wave tube (TWTs).

Abstract:Mezzo Technologies fabricates high performance micro tube heat exchangers. In this proposal, Mezzo proposes to fabricate a heat exchanger to interface between helium, which is the working fluid used to cool a variety of superconducting components on Navy vessels in the future that will require cryogenic cooling, and cold neon gas, which is supplied by a Reverse Brayton cryocooler. Mezzo's approach, which builds upon a previous effort for the Missile Defense Agency as well as continuously evolving manufacturing capablity will result in a unit which can cool 20 grams/second of helium at 2000 kPa, with an effectiveness of greater than 90%, very low pressure drops, and with a weight of approximately 10 pounds. The material costs associated with this unit will be substantially less than $1k, and the acquisition costs will meet the goal specified in the solicitation. The unit will also be compact and extremely robust.

Title:Advanced Foam-Based Cryogenic Heat Exchanger
Abstract:Cryogenic heat exchangers for cooling gaseous helium are hampered by the fact that helium is a low-density gas. As a result, heat transfer coefficients tend to be low. To compensate for this, Ultramet will design and fabricate an open-cell foam-based heat exchanger using technology that was originally developed for high-power microwave integrated circuits for naval radars. In that application, heat fluxes over 1 kW/cm2 were absorbed by the foam while simultaneously maintaining a surface temperature of only 53°C. Using the models that were developed in that work, an analogous system will be developed using low-cost, high thermal conductivity foams. By using foams to create a compact heat exchanger, the heat exchange surface area can be increased by two orders of magnitude relative to a parallel-plate heat exchanger, and the overall effectiveness of the heat exchanger can be increased by roughly a factor of five.

There are two major areas where technology advancements can be made that not only provide reliable bitts and chocks for use onboard U.S. Navy ships, but also have implications for other military and commercial applications. The first is the application of high lubricity, lubricant free, composite bearing surfaces on cylindrical and linear bearing surfaces; the second involves the use of advanced sealing technology to provide operational integrity even under highly dynamic load force fluctuations and extreme environmental conditions.

Title:Retractable Advanced Mooring System (RAMS)
Abstract:Retractable mooring fixtures are a critical component on the flight deck of a DDG51 class Navy ship. The chocks and bitts must be recessed below the deck level for helicopter operations, while reliably and easily deployed for mooring situations. The current mooring fixtures do not stand up to the highly corrosive environment of the flight deck and the lack of maintenance reduces the reliability of their performance. Midé’s Retractable Advanced Mooring System (RAMS) aims to make the mooring fixtures corrosion resistant to reduce/eliminate required maintenance and increase the reliability so they can easily be deployed when necessary. Eliminating maintenance allows for reduced manpower while also lowering the lifetime cost and extending the overall life of the fixtures. RAMS will also ease the deployment of the mooring fixtures, allowing for simplified and reliable use. Midé proposes to leverage its success with bulkhead shaft seals on the DDG51 class ship to further reduce unnecessary maintenance on the ship so that focus and time can be spent on more critical operations. Midé’s knowledge of sealing in highly corrosive environments and ability to simulate those functions using in-house test equipment makes RAMS a strong candidate to solve the current problem for the Navy.

Title:Silent Cooling Technologies for Submarine Electronics
Abstract:Advanced Cooling Technologies, Inc. (ACT) proposes to develop a thermal management system for cabinet cooling that focuses on the use of silent and primarily passive cooling methods. The passive cooling methods selected have inherently low thermal resistances and will allow the ultimate heat sink to operate at a temperature significantly higher than the current solution. A higher temperature sink allows for a reduction in the volumetric flow rate of air required for cooling. The goal is to either completely eliminate the need for forced convection at the ultimate sink or significantly reduce the required flow rate. Doing so will enable the use of natural convection only or large diameter, low speed fans, respectively. Both of which will reduce the noise produced by the electronics cabinets while still providing the cooling required by the electronics. ACT will work with our partner to customize the cabinet design for integration of the proposed thermal management system. This customization will include optimization of air flow paths for natural convection, if feasible. At the end of Phase I, ACT will provide an advanced cabinet design with an integrated, silent thermal management system for review by Navy personnel.

Title:Development of an Active Electronics Enclosure Thermal Management System
Abstract:As shipboard control electronics continue to evolve, electronic systems inevitably incur hardware changes. However, these system changes often require sound recertification of the electronics enclosure, which can be a very costly and time-consuming process. Therefore, it is desirable to build a silent electronics enclosure to avoid the recertification process. Mainstream proposes developing an active thermal management system for shipboard control electronics for Ohio-class submarines that can acquire heat from air- cooled components and reject it to the ambient environment. We estimate that the enclosure will operate below typical “quiet room” sound levels (40 dBA), which is less than 1/8th of currently used exposed tubeaxial fans. In Phase I, Mainstream will design the TMS, as well as experimentally demonstrate its functionality in our environmentally-controlled facilities. In Phase II, Mainstream will further optimize the cooling system and produce a pre-production environmentally-sealed enclosure with integral TMS. The proposed TMS leverages COTS components and Mainstream’s design expertise, leading to a low-risk, high-reward program capable of rapid transition to the Navy for Ohio-class submarines.

Title:Autonomous Foam Monitoring and Control for VCHT Systems
Abstract:Vacuum collection, holding and transfer (VCHT) systems are used on the newest Navy ships to reduce collected sewage volume to achieve desired holding capability when operating in littoral waters where discharge is restricted. Vacuum collection systems use sewage powered ejectors to discharge urinal and water closet waste into holding tanks that are vented to atmosphere. These high velocity multiphase flows from sewage powered ejectors can cause foam buildup. Luna and our team members BIW, Evac and Nalco propose to resolve the holding tank foaming issues by developing an automated foam detection and control system that is compatible with existing and future VCHT systems. The foam control system will be based on novel induction sensors with embedded processing to automatically recognize foam generation. The sensor will be robust to survive the demanding VCHT environment, and sensitive enough to discriminate foaming from fouling and normal tank conditions. When a foaming event is detected, the system will initiate delivery of environmentally compliant defoamer and antifoaming agents via an automated chemical delivery system that is integrated with the VCHT system.

Title:Automated Non-Destructive Foam Sense and Control Unit
Abstract:To address the Navy’s need for a defoaming system, Physical Optics Corporation (POC) proposes to develop a new Automated Non-Destructive Foam Sense and Control Unit (DEFOAM) based on a novel low- and high-power ultrasonic detection and mitigation technique. The novelty of POC’s DEFOAM system lies in its multi-transducer beamforming approach, which results in a nonlinear effect at the intersection of multiple acoustic beams. This approach forms localized pressure and force gradients, which disintegrate the foam. Moreover, the system is entirely external, as it can operate through tank walls; it is also completely automatic, eliminating humans-in-the-loop. POC’s DEFOAM does not use any chemical agents nor does it require any modifications to existing tanks; it does not require opening the tanks to feed in deforming chemical agents. The DEFOAM system reduces shipboard crew labor and therefore, maintenance and ownership costs, directly addressing Navy requirements. In Phase I, POC will demonstrate the feasibility of foam detection and counteraction capabilities by developing and testing a limited-capability DEFOAM prototype. In Phase II, POC will expand on this development, producing a fully advanced and field- deployable DEFOAM system, ready for certification and qualification, that meets the performance goals developed in Phase I.

Abstract:The Navy in support of the sailor has identified the need for an advanced ballistic shield for Crew Served Weapons Stations that will allow for a required level of ballistic protection without interfering with other shipboard duties that need to be performed. This proposed system will protect the sailor from the increased asymmetric threats that are faced on the high seas as well as during close shore or in port operations by either being reconfigurable or non configurable. GS Engineering has a solid understanding of the challenges of this effort as well as the technologies and materials that should be utilized to fulfill the design requirements. GS Engineering will propose a family of ballistic shields that provide the required level of protection while being reconfigurable to allow for line handling and underway replenishment (UNREP). These same shields will be designed for shipboard design conditions such as wave force. GS Engineering will leverage its actual successful program experience as well as SBIR experience in developing and integrating ballistic solutions for tactical vehicles coupled with our experience in naval operations to deliver a technically innovative solution that meets or exceeds the program requirements.

A unique composite materials system will allow this team to develop a solution that meets or exceeds the required ballistic protection while being able to withstand the uniquely harsh environment present on seaborne vessels (e.g., wave slap). This composite materials system, being metallic in nature, simplifies the design of a reconfigurable system which KP has identified as a key element of this effort. The Phase I effort will include an engineering analysis and design of several potential configurations, which ultimately will be down-selected to include both a reconfigurable and non-reconfigurable design. The Phase I Option will optimize and demonstrate ballistic performance of the unique composite armor system, leading to the fabrication and delivery of a functional prototype as part of a Phase II award.

Abstract:The objective of the proposed program is to develop innovative algorithms and techniques to automatically detect, classify, and uniquely identify emitters exhibiting multi-dimensional agilities, extremely wide band RF distribution, high time-bandwidth coherent characteristics, and solid state power amplifier technologies. The proliferation of agile emitter types has surpassed the ability of current EW systems to de-interleave and identify emitters in a dense and complex signal environment. Improved automated signal analysis and emitter classification is required to maintain an accurate real-time view of the environment, thus allowing the Electronic Warfare Support operator to perform his primary missions of maintaining ship safety and providing complete situational awareness to decision makers. Our goal is to develop an open architecture solution that can support multiple sensors and is easily extensible to address the evolution of future radars.

Abstract:This SBIR develops new innovative clustering and de-interleaving algorithms, leverages and refines existing algorithms and software, and integrates them within an open architecture framework to address a wide variety of radar signal classes for a submarine EW/ISR application. The proposed effort addresses several challenging emitter waveform classes for which current approaches are noted to have problems (per solicitation). This effort leverages RAS Multi-Algorithm Unique Emitter ID SBIR Phase I/II and end-to-end Directed ELINT Process (DEP) software modules (C/C++ and MATLAB) for clustering, RF Agile clustering, cluster correlation, track association, and emitter typing. It exploits previously developed Specific Emitter Features (SEF), not only for Specific Emitter ID (SEI), but also for cluster correlation, specific emitter tracking (SET) and RF agile processing. Approaches are assessed and selected for PHASE II software development and demonstration within the Processing Layer of the NAVSEA NexGen EW system architecture concept. Interface and control software, operating within an Ozone Widget Framework, enables automatic system operation to minimize operator interaction (with manual override and configuration control) provide high confidence emitter processing and reporting. After Phase II, RAS will work with platform primes and the government to install and demonstrate the technology on a suitable submarine platform testbed.

Abstract:Avogy has a unique approach to producing vertical GaN-on-GaN power devices that have fundamental advantages over silicon, silicon carbide, and lateral GaN devices. With this SBIR funding, we will demonstrate the feasibility of a normally-off vertical GaN transistor with a blocking voltage over 5000V, a threshold voltage greater than 1V, and specific on- resistance less than 30 mohm-cm2.

Title:Automated PrOduct GEneration and Enrichment (APOGEE)
Abstract:Creating information products to answer “Tell Me About” questions requires the ability to identify key pieces of information relevant to a complex set of content requirements. Complicating matters, these key pieces of information are scattered across data stores and buried in huge volumes of data. This results in the current predicament analysts find themselves; information retrieval and management consumes huge amounts of time that could be better spent performing analysis. The persistent growth in data accumulation rates will only increase the amount of time spent on these tasks without a significant advance in automated solutions for information product generation.We propose a system called Automated PrOduct GEneration and Enrichment (APOGEE). APOGEE automates the creation of information products; learning the creation process by example. There are three stages to APGOEE’s workflow; first, using clustering and other machine learning techniques APOGEE learns the content models for a range of information products; next, using a search-and-align based methodology, APOGEE maps the content models to the semantic structure underlying unstructured text; finally, APOGEE uses the learned content model and semantic mapping to automatically generate new information products. All this can be done on the fly without requiring predefined information product templates or ontologies.

Title:Query Language for Analytic Product Support (Q-LAPS)
Abstract:The tremendous amount of information available to the analyst is both an opportunity and a problem. Clearly, more information provides analysts with a better foundation for their analyses. However, as the amount of information increases, analysts are finding it more and more difficult to take advantage of the wealth of information, due to the difficulty in extracting the information that they need at the time that they need it, in order to produce actionable intelligence to assist planners and warfighters. Knowledge Based Systems, Inc. (KBSI) proposes to conduct research leading to a “Query Language for Analytic Product Support” (Q-LAPS) that enables analysts to effectively query unstructured and semi-structured data sets for information that is relevant and timely for generating analytic products. The proposed approach strikes a balance between the need for high quality and accurate results and ease of use and minimal training for the analyst.

Title:Tell Me About
Abstract:Our proposed work addresses the significant challenges in providing responses to complex “tell me about” questions that intelligently consolidate relevant information into a finished dossier. We will induce the semantic signature of the question target by using relevant sample intelligence reports to derive a set of information requirements which will be used to create a finished dossier. These information requirements will drive the retrieval of relevant textual passages which will be semantically enriched using novel approaches to relation discovery and frame induction. The entities and events discovered in these enriched passages will then be linked to a structured knowledge base allowing for the addition of pre- processed factoids about related entities and events. Finally, this information will be fused into a final, finished dossier which will provide a rich source of links and information for the analyst. We will explore a hybrid strategy with ties to research in Automatic Wikipedia generation that will augment and enhance LCC’s existing state-of-the-art Ferret QA system. In addition, we will leverage existing state-of-the-art natural language understanding and content extraction in order to acquire the semantic and pragmatic information necessary to satisfies the demands of today’s information analysts with a single finished dossier.

GROK presentsthe generated reports with a novel, uncluttered interface designed tosave the analyst time in consuming the knowledge in the report, andfinding the next piece of knowledge they need.

In essence GROK augments themachine knowledge representation with a catalog of different approachesto express that knowledge. The expression catalog spans the wholecorpus, allowing GROK to properly present domain specific vernacular.GROK also automatically builds up a flexible context which the analystcan intuitively manipulate to produce concise reports focused on onlythe information they need.

Title:Cloud-Based Tell-Me-About Q&A System
Abstract:The essence of the problem is to allow military intelligence and operations staff to pose “tell me about” questions concerning an entity, and obtain a finished information product. There are 4 main technical challenges / sub-problems: a) Question content modeling: The question needs to be semantically mapped to an ontology. b)Semantic enrichment of unstructured text: Unstructured data (text, images etc.) needs to be marked-up with semantic tags that relate the content to the ontology. c)Sufficiency tracking of discovered content: Relevant content needs to be discovered and its sufficiency evaluated as an adequate response to the question. d)Presentation of finished product: The answer needs to be presented as a report in a familiar format such as MS Office or Adobe PDF. We present a cloud-based approach to address all these issues.

Title:Team Performance Metrics for Command and Control of Unmanned Systems
Abstract:The primary objective of the proposed research is to develop, and to demonstrate the feasibility of a mathematically rigorous approach for modeling and evaluating human supervisory control of multiple unmanned and/or autonomous vehicles. This high-level objective is decomposed into three inter-related goals: (1) the development of a mathematical model of human supervisory control, for individual operators as well as for cooperative teams of operators, (2) the study of team performance metrics induced by comparing the team’s operation and the overall system operation against baseline operations, with all of these operations represented quantitatively using the aforesaid models, and (3) the identification of diagnostic information from these induced metrics and the identification of feedback information from these metrics for improving the performance of the team of operators. A secondary objective of the proposed work is to develop a framework that enables clear and precise definitions of the concepts of futuristic operations, such that this definition directly influences various elements within the models – and, by consequence, the induced metrics – of supervisory control.

Title:Team Performance Metrics for Command and Control of Unmanned Systems
Abstract:In today’s world, unmanned vehicles play ever-increasing roles in the military, firefighting, deep-sea and space exploration, and border defense. There is often a one-to-one ratio between operator and these unmanned vehicles; in some systems, an entire team of humans is required to operate a single vehicle. The Navy’s ambitious future vision of autonomous vehicles and sensors involves tens – even hundreds – of vehicles and sensors being supervised by a single individual or very small team. To achieve this radical shift will require innovative new methods of monitoring, managing, and coordinating these vehicles and sensors – and a significant change in the current concept of operations. Whereas today’s unmanned vehicles or sensors serve primarily as a remote extension of their operators and have very little autonomy, tomorrow’s autonomous vehicles and sensors will serve more as active, “thinking” members in a vast, distributed, multi-echelon “team” supervised and directed by a human(s). Measuring and optimizing the performance of such human/machine teams in real time will require new kinds of metrics and methods of measurement. This proposal outlines a plan for developing and validating the required metrics and methods by way of a new concept for structuring the data and information exchanged between human and machine.

Title:Causal Model-based Measurement and Visualization System (CMVS) for Team Performance in Command and Control of Unmanned Systems
Abstract:This proposal is to develop a “Causal Model-based Measurement and Visualization System (CMVS) for Team Performance in Command and Control of Unmanned Systems.” CMVS will include methods, metrics, displays, and quantitative analysis to diagnose, visualize, and help remedy deficiencies in performance of both individual operators and teams who manage dispersed heterogeneous unmanned systems. Unmanned vehicles (UVs) are being developed and fielded at an unprecedented rate; but maximizing the benefits of autonomous or semi-autonomous robotic vehicles requires smooth integration of decisions by UV operators, consumers of the information provided by the UVs, and other command and control personnel. CMVS will identify the critical new dimensions of manned/unmanned team performance, develop metrics for capturing them in real-time scenarios and operations, integrate the metrics into a valid overall evaluation, and show how the evaluations may be used for recommendations regarding personnel, training, technology, training, and/or aiding. The key to our approach is the innovative use of an evidence-based causal decision model. The model will provide a basis for diagnosing deficiencies and recommending remedies that is grounded in cutting edge research on individual cognition, team process, and automation management. In addition, the model will provide for an integrated team performance measurement system.

Title:Team Performance Metrics for Command and Control of Unmanned Systems
Abstract:The increase in unmanned systems, also known as UxVs, on the battlefield creates the need for coordinated activity among multiple UxVs that work effectively in collaboration with the Warfighters who must be able to rapidly and easily command their operations, insure their compliance with intent in a highly unpredictable world, and receive needed situation awareness (SA) from their sensors. In order to move toward a lower, more efficient UxV to operator ratio, it is critical that we develop a better understanding of real time hybrid human- UxV team performance, so that key decision makers can assess transaction efficiencies given autonomy and control parameters. Unfortunately, little has been done to develop robust and valid metrics of hybrid human-UxV team performance. A key to improving the performance of human-UxV teams, then, lies in developing these metrics so that decision makers can assess performance in real time through intuitive visualizations. To meet this need, SA Technologies proposes to use both their performance measurement assessment system developed in past research and their cutting edge, principled situation awareness- oriented design process (SAOD) to develop a theoretically-derived Actionable Performance Evaluation Index (APEX) analysis and visualization tool. APEX will facilitate peak performance for hybrid human-UxV teams.

Title:Interactive Generative Manifold Learning
Abstract:Nonlinear manifold learning is an active area of mathematical research. Unfortunately, the extant literature has far less to offer on the problem of interactive nonlinear manifold learning. In other words, satisfactory nonlinear manifold learning approaches that put the ``human in the loop' are yet to be fully developed. Human steering of such calculations promises several advantages including, leveraging human expertise in sparse data environments, maximizing efficiency by allowing computational resources to be focused on areas of interest to the user, and augmenting the amount of useful information the user can glean from large and complicated data sets. Several questions immediately present themselves. What if the data is too voluminous to be processed all at once? What if one does not have all possible data at hand and must decide what additional data would be the most informative to synthesize, or to acquire? How does one best take advantage of the user's expertise and inject it into the problem? These considerations lead one inexorably to five core interactions between the user and the manifold learning algorithm that are not fully addressed in current manifold learning algorithms, namely: interpolation, extension, resampling, extrapolation, and visualization of the data by the user.

Title:Interactive Generative Manifold Learning
Abstract:Exploratory data analysis is the foremost step in selecting appropriate statistical learning algorithms specialized to a dataset. We have proposed a generative framework for visualizing high dimensional data as low-dimensional manifold embedded in a high dimensional space. The method allows user to conveniently explore the space using fewer dimensions while still capturing the principal modes of variations of the high dimensional data. Specifically, we employ Gaussian Process Latent Variable Model (GPLVM) and Spectral Latent Variable Model (SLVM) to learn low-dimensional representations of the data. Probabilistic mappings between the embeddings and the original space facilitate efficient interpolation in the latent space as well as fast visualization of the interpolated latent points in the original space. To allow the user to span the manifold in an intuitive manner, we develop supervised and semi-supervised tools to relate the latent space to the meaningful feature space. These enable computation of principle direction for each point in the latent space to allow the user to traverse in a meaningful way. Further, we have proposed a principled approach to extrapolate the latent space by predicting the manifold structure in regions lying outside the existing domain of the data.

Title:Online Interactive Generative Multiscale Manifold Learning
Abstract:One of the main obstacles to the useful exploitation of dimensionality reduction, both linear and nonlinear, is the lack of effective synthesis methods to generate examples in the original exploitation space, as opposed to the low dimensional parameter space. The ability to interactively navigate in the appropriate relevant low dimensional representation, and simultaneously observe the related “original” data modality would enable both sensor fusion and enhanced recognition and identification. Our team has developed an initial theoretical framework that promises to provide this ability, which we propose to demonstrate as Fast Online Interactive Generative Multiscale Manifold Learning.

Title:Interactive Generative Manifold Learning
Abstract:Signal Innovations Group proposes a hierarchical Bayesian approach for non-linear dimensionality reduction that addresses three key challenges: learning a reversible mapping from a high-dimensional observed space to a low-dimensional embedded space, learning the dimension of the embedded space, and generating new high-dimensional data for a given location in the embedded space. The proposed generative approach is statistical and jointly learns the probabilistic reversible mapping and the dimension of the embedded space. The proposed approach also enables new high-dimensional data to be embedded in a previously learned low-dimensional space. A hierarchical Bayesian method is also proposed to learn a non-linear dynamic model in the low-dimensional space, allowing joint analysis of multiple types of dynamic data, synthesis of new dynamic data in the low-dimensional space, and mapping synthesized data to the high-dimensional observation space. The models are designed to uncover the relevant characteristics and structure of data through non-linear dimensionality reduction, which enables a human analyst to identify and explore the characteristics in the low-dimensional manifold space and generate new unobserved high- dimensional data.

Title:Cost-Effective Technologies for Fabrication of PiezoCrystal Vector Velocity Sensors
Abstract:Applied Physical Sciences (APS) has developed a plan to improve the design and development of submarine towed array vector sensors that employ single crystal accelerometers so that they meet Navy specifications, but do so at significantly lower cost relative to earlier variants. Tasks in the Phase I study include developing a comprehensive cost-model which will ascertain the feasibility of various fabrication approaches for all the components that comprise the entire sensor. As a part of this process, APS has teamed with TRS Technologies to evaluate innovative electroding and bonding techniques to reduce the costs single crystal accelerometers. With that, the proposed effort centers on a series of analytical and numerical evaluations, proof-of-concept experiments, and an assessement of a prototype vector sensor suitable for towed array applications.

Title:Cost Effective Manufacturing of Piezoelectric Acoustic Sensors (CEMPAS)
Abstract:Arrays of vector velocity sensors have exhibited major system improvements over traditional omnidirectional hydrophones in undersea acoustic sensing. Compact accelerometers made from relaxor piezoelectric crystals are the key element which allow for the improved functionality of the vector velocity sensor arrays. These relaxor piezoelectric crystals are extremely sensitive and compact; but manufacturing of sensors incorporating these crystals have traditionally been costly. Midé’s patented piezo manufacturing line and its over 20 years of experience with manufacturing piezoelectric packages makes them the ideal candidate to develop an effective and low cost manufacturing process for accelerometers incorporating relaxor piezoelectric materials. Midé’s proposed technology drastically reduces assembly needs for piezo based vector velocity sensors while improving the durability of the piezoelectric element. In the manufacturing process piezoelectric packages are produced with necessary electrical connection to the piezoelectric element embedded. Because of the large number of sensors required, Midé’s automated piezo production line provides the greatest potential for cost effective manufacturing

Title:Cost-Effective Technologies for Fabrication of PiezoCrystal Vector Velocity Sensors
Abstract:Arrays of vector velocity sensors provide major system gains over legacy arrays of omnidirectional hydrophones in bottom moored and submarine/unmanned undersea vehicle (UUV) towed applications. For example, the left-right ambiguity of legacy devices is eliminated and an array sensitivity null can be steered at a noisy source of interference making much quieter targets detectable. The exceptionally sensitive, compact accelerometers made possible by the new relaxor piezocrystals are the key enabler for this performance enhancement. Since these sensors are only millimeters in size and are required in large numbers, a major technical hurdle for this technology is to devise cost- effective ways to manufacture the vector sensor. A cost model, relating the component and touch labor costs, is needed for the various design options. Once the dominant cost drivers have been identified, approaches to reducing costs, either through reducing component or labor costs, are essential if the Navy is to benefit from the new technology.A variety of accelerometer designs are under development for these vector velocity sensors, for example, cantilevered-beams, shear-mode, and pressure-gradient devices. While acoustic performance is the primary driver in the choice of device configuration, cost will ultimately determine the acquisition choice.

Title:Cost-Effective Technologies for Fabrication of PiezoCrystal Vector Velocity Sensors
Abstract:We propose to develop cost-effective velocity vector sensor technology by reducing costs to the accelerometers within the device. By optimizing both crystal and hardware, single crystal materials costs can be reduced. TRS will also evaluate assembly of sub-structures to reduce labor through automation (i.e. pick-and-place or other bulk processing). Through modeling and prototype assembly, and development of a cost model, key factors in accelerometer costs will be determined and possible solutions to reducing these will be provided at the end of the program. The prototype built will be compared with legacy devices to insure performance meets requirements.

Title:SEASCAPE: System for Efficient Agile Signal Classification of Adversary Produced Emitters
Abstract:Tactical electromagnetic environments have become much more complex over the last two decades with a higher density of more diverse and more sophisticated emitters. Signals of interest are becoming much more frequency agile and have a lower probability of intercept, making it much harder to detect and identify them. To support the Navy in maintaining a combat advantage in dense signal environments, we propose a System for Efficient Agile Signal Classification of Adversary Produced Emitters, or SEASCAPE. SEASCAPE provides an energy-efficient, dynamic, hierarchical ensemble classifier that accurately fingerprints sophisticated emitters while characterizing detection uncertainty and reliability. SEASCAPE is supported by a signal processing workbench and a fusion module to evolve the classifier and its supporting feature sets over time as new agile signals of interest are encountered.

Abstract:In this program, TrellisWare Technologies, Inc. proposes to develop a three-stage architecture that detects, identifies, and classifies frequency agile signals across extremely wide bandwidths (e.g., 10+ GHz).

Although TrellisWare proposes to focus on off-line processing of synthetic data in Phase I and real- world data in Phase II, the proposed sub-Nyquist signal processing techniques would all support real-time operation in an FPGA-accelerated SIGINT analysis platform.

Title:Predictive Model for Imaging Underwater Objects through the Air-Sea Interface
Abstract:The science of Mine Countermeasures (MCM) is a challenging and multidimensional problem that involves the detection and classification of sea mines both underwater and at the surface. In recent years, MCM has undergone dramatic advances in detector technology, computational power, and algorithmic maturity giving the potential for a “never-before-seen” capability to detect and classify sea mines. Essential to the continuing success for application of EO systems to the MCM problem is the ability to model targets in the marine environment to gain a better the understanding of target phenomenology. This will pave the way to better EO sensor designs and more robust detection and classification algorithms. Making high fidelity models and realistic simulations possible is the fundamental theory derived from numerous investigations into the details of radiative transfer within the ocean environment. Jerlov (1979), Gordo (1988), and Mobley (1993). However, McLean and Freeman (1996) extended these simple models to include wave effects of the ocean surface. Leveraging this research and well validated propagation models, Areté Associates will develop a robust, high-fidelity electro-optical radiative transfer model to predict the time- varying visibility of submerged objects.

Title:Compact High-Power Broad-Band Spherical PiezoCrystal Acoustic Source for Countermeasures
Abstract:Acoustic countermeasures, deployed from ships and submarines, serve as decoys by mimicking the acoustic signature of the vessel. These autonomous devices require a highly efficient, high-power, broadband, compact acoustic source to achieve their goals. The combination of the most effective acoustic radiator design (i.e., a sphere) and the new high- coupling, high-strain relaxor piezocrystals provides an optimum combination to meet these exacting requirements. The technical challenge is to devise a cost-effective method of making a tiled approximation to a sphere. Other issues to be addressed, primarily by modeling, include specifically the actuation mode (d31 or d33) of the crystals, whether a fully active tiling is appropriate or whether some passive tiles should be included, and the implications of these choices for the drive electronics.In these applications both cylindrically and spherically shaped sources made from legacy piezoceramics have been employed with good results. Segmented cylinders of the relaxor piezocrystals provide a dramatic enhancement over the legacy piezoceramic cylinders, matching their acoustic performance in a package one hundredth the size requiring only half the energy. A tiled sphere (like a soccer ball) of piezocrystals will provide a similar step improvement over legacy piezoceramic technology.

Title:Analytical Processes for Predicting Nanosecond Response of Highly Rate-Sensitive Materials
Abstract:Ballistic and blast protection of both the crew and vital equipment onboard U.S. Navy surface ships and carriers is a critical component in the design of topside structures on these vessels. Materials such as glass, Plexiglas® and polyurea are being considered and implemented for protection in these applications due to their low density and inherent damage mechanisms which absorb large amounts of energy under high-velocity impact or blast loading conditions. Likewise, these material systems are being used in layered or laminated configurations to exploit the benefits of each individual material. However, the ability to numerically simulate these materials constitutive and damage behavior does not readily exist in traditional analysis tools. Therefore, for this effort we have proposed to utilize and implement three new constitutive material models for conventional glass, PMMA, and polyurea/polyurethane. The material models will initially be implemented within the shock hydrocode CTH and will allow for more accurate simulation of ballistic impact events on the material systems of interest and also offer a more efficient armor system design approach.

Accurate EOS and rate-dependent constitutive (flow, yield stress, damage) models for plate glass, PMMA and segmented elastomers will be developed based upon equilibrium and non-equilibrium molecular dynamics simulations and will be validated through direct comparison of predicted impact behavior with experimental measurements. MD simulations will also facilitate development of improved interfacial models needed for prediction of wave propagation in multilayered materials. The material point method (MPM) will implement these models as well as improved 2- and 3-D crack propagation, fracture, failure and materials interface models, allowing for accurate numerical assessment and optimization of layered structures of various materials and geometries to resist ballistic and blast impact.

Title:Technologies for Enabling Warfighter Intuitive Decision Making
Abstract:Traditional concepts of neural-machine interface use brain signals as: control inputs; to assess neurocognitive states for modification of information delivery to improve human performance; to guide selection of image sets. We propose a revolutionary concept of interfacing Electrical Geodesics’ technology (sensors and brain signal analysis) with Icosystem’s interactive evolutionary computation (IEC) (search and decision support) for certain data mining and discovery tasks. IEC combines the unique ability of humans to instantly detect patterns with the computer’s ability to generate millions of solutions. This approach enables a significantly broader exploration of model space while always satisfying the model constraints. While the task described is simple for a proof-of-concept, the implications can dramatically improve the quality and thoroughness for a range of analytic and discovery tasks.

Title:iSee
Abstract:iSee (IC the augmentation of intuitive decision making using Computation) is a framework that will enable accelerated, accurate intuitive Decision Making (iDM). Knowledge Based Systems, Inc. (KBSI) will model iDM based on the functioning of our brains to improve decision-making performance by enhancing the ability to see through the information clutter effectively. The goal is to blend rapid data processing capabilities of computers with intuitive decision making skills of humans to improve human information throughput and decision making laid out in this research topic.The KBSI iSee framework proposes to enhance intuitive decision making by leveraging the following technologies: Monitoring human cognitive state using non-intrusive sensors Processing information into a form that can be digested by the user under the existing conditions of stress Presenting individually customizable visualizations overlaid on the real world, and Alerting the user with additional subtle sensory feedback such as audio, vibration and olfactory The key feature is the use of ontology and Bayesian networks to capture mental models that can be used to process higher level tasks such as sensemaking and “intelligent explanations that have not been addressed in detail in AugCog systems.

Title:An Immersive Approach to Intuitive Information Processing and Decision Making
Abstract:In recent years, research in the areas of human-computer interaction and cognitive psychology have revealed major shortcomings in software systems designed to support human analysts in processing large volumes of electronic information. In some cases, technologies developed to automatically fuse information have been found to obscure the nuances required for people to adequately make sense of an emerging situation. We instead propose to focus our attention on employing new instrumentation cost-effective technologies to monitor brain activity, eye gaze, and facial expressions in order to detect initial relevance as well as changes in user intent. These observations, interpreted through models of intuition and sensemaking, will enable the proposed system to alter information displays and the human-machine interaction in ways that not only reduce cognitive load but improve decision quality by enabling users to rapidly elaborate, question, evaluate, compare, and reframe their interpretations of data. During Phase I we will devise measures of intuition and pair them with appropriate sensor technologies. We will also demonstrate through limited experiments how these measures can be used to improve the speed and effectiveness of decision making.

Title:Virtual Infrastructure for Reliable Ad hoc Mobile Network Architecture
Abstract:Military networks are composed of mobile nodes with different, often highly specialized mission functions and capabilities. But node mobility in a noisy, often-obstructed, adversarial communications environment causes nodes to lose contact with the network frequently and unpredictably. This SBIR proposes a Virtual Infrastructure for Reliable Ad hoc mobile (VIRAL) Network Architecture. VIRAL will be designed to provide distributed service in real time ad hoc fashion that is more scalable, robust against failure and allows synergistic use of resources. VIRAL network integrates the data centric storage approach with the distributed storage system to formulate the architecture that grants data access independent of changes in the network behavior and topology. VIRAL incorporates disruption tolerant network protocol to ensure that data is resistant to intermittent connectivity between nodes. By replicating data in multiple paths, VIRAL assures that the data is highly available even with node loss. VIRAL implements a unique authenticate and security features that would be secure from outside eavesdropping or loss of node to destruction, capture, or compromise by an enemy. Lastly, VIRAL has predefined metadata (a file that describes the contents and context of data files) and user defined metadata, so the data can be efficiently and selectively access.

Title:Data Storage and Transmission Strategies for Wireless Ad Hoc Networks
Abstract:The Department of Defense Joint Vision 2020 aims to create a force that is dominant across the full spectrum of military operations through information superiority. Achieving these objectives implies the ability to dynamically share and store data among potentially thousands of participants at the tactical edge, including users of Handheld, Manpack, and Small Form Fit (HMS) radios. However, this potentially exposes these platforms to capture, compromise, and cryptanalytic attacks.Concentris Systems proposes to leverage recent advances in peer-to-peer storage to provide a distributed data storage service for mobile ad hoc networks in which confidential information stored on individual nodes is not vulnerable to concerted cryptanalysis. The proposed system provides a generalized approach to discovery, replication, reliability, and availability for data in the tactical ad hoc network, and offers a roadmap for data persistence when connected to back-end enterprise networks. The solution will provide interoperability with key standards required by the DoD Network-Centric Operations objectives to ultimately produce a cost-effective, dual-use, commercially-viable product. The design and implementation of such a framework would greatly accelerate the realization of the DoD’s Joint Vision 2020 objectives for highly mobile missions in non- traditional areas of operation.

Title:Data Storage and Transmission Strategies for Wireless Ad Hoc Networks
Abstract:In the tactical wireless ad hoc network, all networking nodes are vulnerable to various security attacks. Therefore, the centralized data storage is unable to protect the tactical data once the storage device is compromised by an adversary. Distributed data storage is the alternative that the data are securely and reliably spread on the networking nodes with certain redundancy, offering high data protection and data resiliency. In this project, we developed Secure Distributed Data Storage (SD2S) by using Secret Share (SS) algorithm and Elliptic Curve Cryptography (ECC) for mobile ad hoc networks. SD2S is a novel (n, t) data storage system where the proposed SS algorithm coverts the data into n shares. Each share leaks nothing on the data and the original data can only be recovered from t shares. ECC provides an additional layer of data protection. The data is protected even if all the shares are compromised by the adversary. SD2S can be used for unsecure storage nodes (e.g., unsecure wireless links and hostile storage nodes). The internal and external attacks on distributed storage system are investigated to prevent potential adversaries. SD2S is superior to all other existing approaches in terms of data protection and performance efficiency.

Title:DataGuard: A Secure, Reliable and Efficient Data Storage and Transition System for Mobile Ad Hoc Network
Abstract:We propose a secure, reliable and efficient data storage and transition system, DataGuard, for wireless ad hoc networks. As a distributed system, DataGuard integrates various coding techniques, data migration protocol and service evaluation model to enable secure data storage and efficient data access in wireless ad hoc networks. We adopt various coding techniques including erasure coding scheme, threshold crypto algorithm and symmetric crypto primitives to protect data at rest and in transit against eavesdropping and Byzantine attacks. Moreover, we propose to develop the data migration protocol that allows the data storage system to self-adapt to the network dynamics. Additionally, we propose to develop the service evaluation model that allows the data users to evaluate the data delivery service provided by the data storage nodes. The combination of coding schemes, the data migration protocol, and service evaluation model in DataGuard significantly improves the data availability with distributed implementation in wireless ad hoc networks. Finally, in the proposed effort, we will demonstrate the feasibility of the proposed coding techniques, data migration protocol and service evaluation model in a workable data storage and transmission prototype for wireless ad hoc networks.

Title:SeaCube – Radar Altimeter for CubeSats
Abstract:Busek Co. Inc. with expertise in spacecraft electric propulsion systems, including microwave generated plasmas and CubeSats, and ImSAR LLC with expertise in small Synthetic Aperture Radars (SAR) for Unmanned Arial Vehicles (UAVs) have teamed up to develop an ocean sensing radar altimeter called SeaCube. SeaCube will fit into 1U of a 3U CubeSat, operate in pulsed mode, consume low orbit average power and produce acceptable data rates. The concepts underlying radar altimetry began after the Navy’s Moon Bounce program showed accurate ranging measurements. NRL realized that similar radar from orbit to the ocean surface could accurately determine the ocean surface state. This resulted in a plethora of ocean state measuring satellites, all which are much larger than CubeSats. With this program the Navy is again at the forefront of technology challenging the community to reduce the radar altimeter size to a 1U Cube form factor. Phase 1 of the proposed program is focused on demonstrating SeaCube’s feasibility. The point of departure will be a miniature UAV based imaging radar build by ImSAR called NanoSAR which is already near the 1U form factor. The Phase 2 deliverable will be an EM model of the SeaCube, ready for flight qualification program.

Title:WCDMA Enhancements for Use Rapidly Moving Platforms
Abstract:Wideband Code Division Multiple Access (WCDMA) is the most recent generation of cellular phone technology that is being adopted for commercial, government, and military mission critical systems. One of the key enablers towards adoption of cellular technology in tactical environments is Mobile User Objective System (MUOS). MUOS is an Ultra High Frequency (UHF) SATCOM system the converts a commercial third generation (3G) Wideband Code Division Multiple Access (WCDMA) cellular phone system to a military UHF SATCOM radio system. In this work, the focus is to enhance the current design of MUOS WCDMA so that it can be applied to BS that are installed on rapidly moving platforms. This SBIR implements WCDMA algorithms for installation on rapidly moving platforms by inclusion of an ability to adapt the parameters such as slot-size, interleaving depth, channel prediction time scale as well as algorithms such as channel estimators based upon Rake receivers and Kalman filters to adapt to different RTT, channel coherence time, changes in propagation loss values and variability in Doppler-shifts.

Title:Evolving WCDMA for Extreme Mobility
Abstract:The Mobile User Objective System (MUOS) will provide the warfighter with the tactical ability to communicate in disadvantaged environments. The underlying MUOS concept -- namely, adapting a powerful commercial cellular waveform to a military grade infrastructure - - has applications beyond the initial system deployment. For example, the development of ruggedized WCDMA base station processing payloads would allow the ground station processing to be done aboard the satellite. Furthermore, the geosynchronous satellites of the MUOS system could be replaced by satellites in alternative orbits (e.g., the Molniya orbit) or even unmanned aerial vehicles and aerostats. In order to realize these applications, however, significant innovation is required in WCDMA receiver signal processing algorithm design. To this end, TrellisWare proposes to develop a turbo Rake receiver structure that combines Per-Survivor Processing (PSP) and Adaptive Iterative Detection (AID) to enable reception of the MUOS waveform in severe Doppler environments.

Abstract:WCDMA payloads on fast-moving platforms, such as on satellites in Molniya orbits or on UAVs, will likely be added to the battlefield to assure the warfighter of reliable, ubiquitous communications. The algorithms for handoffs, timing, and Doppler correction suitable for near-Geosynchronous platforms will not be suitable for these fast movers. Power control algorithms may or may not be suitable. This project determines the necessary modifications to commercial and military WCDMA algorithms to support intra and inter platform handoffs, timing synchronization, power control, and Doppler correction.

Abstract:This offer proposes a set of activities to provide an innovative Deployable WCDMA Multi- Band Radio Base Station. The effort entails investigation, trade studies, and architecture design to support an easily fielded, transportable WCDMA Base Station not typical of mainstream communication deployments. The derived solution will support both military and commercial applications where terrestrial or satellite communications may not be available. The investigations for this project will focus on how multi-band, differing protocol (3GPP and MUOS) WCDMA channels can be supported by a single transportable radio base station, and options for interfacing users on these channels to their respective carriers such as the MUOS geosynchronous satellite system. The investigations will specifically address the challenges associated with interfacing a radio base station to MUOS network infrastructure equipment; resulting in a solution that will ensure communications features that meets the needs of the war fighters.

Title:Advanced Software Defined Radio Capabilities and Information Dominance - Applying ANDRO’s Transmission Cyberspace Solution
Abstract:This proposed research is to investigate and validate Software Defined Radio (SDR) based, multi-function portable network sensing and intrusion detection algorithms suitable for small dismounted radio platforms used to support Command and Control (C2) standard sensor interfaces carried in the field and for sensor data exfiltration. A new capability called Transmission Cyberspace is proposed that will enable DoD military SDRs in the battlefield that are in close proximity to hostile foreign networks to be cognizant of their surrounding radio frequency (RF) environment. A novel and robust network discovery capability will be developed to rapidly assess the potential for RF intrusion, cyber attacks or other unauthorized access to SDRs and Cognitive Radio and Sensor Networks (CRSNs) along with implementing effective defense strategies. This will be accomplished through the application of a suite of algorithms that fundamentally exploit the multidimensional and joint orthogonal nature of the RF signal space. A hybrid class of algorithms and techniques will be used, namely: multiobjective optimization, game theory, spectrum sense and adapt, distributed detection, joint cognitive routing and spread-spectrum channelization, and automated modulation classification. A unique physical (PHY) layer protection scheme is then used to thwart attacks and to augment upper layer (data, MAC, network) multi-level security methods to deny cyber attacks and to ensure secure communications and trusted network routing. These algorithms will leverage the SDR’s ability to sense the presence of other wireless networks, monitor those networks and detect when and where hostile intrusion attempts might arise.

Title:NetSAID: Network Sensing, Assessment, and Intrusion Detection
Abstract:Emerging portable software defined radio (SDR) technology has great potential to improve the communication capability of dismounted and Special Forces personnel, as it can quickly acquire the operational information in a hostile environment, and adapt to it based on spectrum needs and available resources. The major challenge lies in the following aspects: effectiveness of spectrum sensing, network identification, effective network assessment, advanced security mechanisms, and spectrum adaptation. However, most of the existing research focuses on the enabling technologies such as spectrum sensing and adaption, but pays less attention to other aspects. Moreover, the current development is still in its early stage and demands further investigation. In addition, to support diverse spectrum of mission requirements and needs, all five aspects should be fully leveraged and equally emphasized. To address this critical need, Intelligent Automation, Inc. (IAI) proposes to develop a dynamic Network Sensing, Assessment, and Intrusion Detection (NetSAID) system on portable SDR platforms to enable the dismounted and Special Forces personnel to rapidly adapt to hostile environments and acquire relevant operational information. The proposed approach will significantly improve the reliable and secure access to battlefield networks, as well as the enhanced support for situation awareness.

Abstract:We propose to develop, implement and demonstrate Multi-Function Cognitive Radio Architecture (MF-CRA), a novel software-defined cognitive radio architecture that simultaneously achieves robust tactical wireless networking and information dominance capabilities for dismounted and special forces personnel. By information dominance we mean the ability for radios to sense, detect, characterize, and neutralize adverse actions (e.g., RF jamming, network intrusions, and communication protocol-aware attacks) caused by hostile entities in addition to their original communication responsibility.The proposed solution is founded on a unique integration of multi-function capable RF front-end designs, signal processing hardware engine based on a mix of FPGAs and DSPs, and cognitive algorithms with extensive signal classification capabilities for native information dominance capabilities.
