| Title: | Lightweight Ballistic Exhaust Grille with Directional Capabilities and Reduced Thermal Signature |
| Abstract: | The Expeditionary Fighting Vehicle (EFV) has two aft mounted exhaust grilles that interface the heat exchangers to the external environment. The current grille design suffers from competing requirements which render its performance less than optimal. In this Phase I project, Infoscitex proposes to conduct research into innovative composite materials and fabrication methods that will enable a grille to meet weight, airflow, ballistic and thermal emissivity requirements, as well as allowing directional capabilities. Following materials selection and evaluation, a first generation design will be created. Subsequently, a cost-benefit analysis will be performed on the design that analyzes the projected performance and costs of ownership. A design will be pursued that allows the new grille to be integrated with the existing housing and mounting flanges. |

| Title: | Ballistic Exhaust Grille |
| Abstract: | New World Associates proposes to develop an exhaust grille for the Marine Corps EFV (Expeditionary Fighting Vehicle) that improves performance and maintains required ballistic protection. The issue with the current design for the EFV is that the exhaustgrille is a heavy system that does not allow flow control (IR signature suppression) with adequate ballistic protection. The modified design will evaluate several design options and will focus on the following primary design criteria: A) Obtain specified ballistic performance; B) Optimize airflow vs. pressure drop characteristics; C) Reduce vehicle infrared signature; D) Minimize weight and manufacturing costs. During Phase I of the proposed program, tasking will include research into available materials that optimize weight reduction and ballistic protection requirements. During this phase, several design concepts will be proposed and evaluated with respect to the EFV performance specification (EFV S/SS Specification Rev J. dated 10 August 2006). New World will utilize its extensive background of ballistic protection of vehicles and airflow design and analysis to solve the proposed problem. |

| Title: | Dual Mode Controlled Ricochet Low Loss EFV Cooling Grille(1001-046) |
| Abstract: | Triton Systems Inc. in collaboration with the Charles Stark Draper Laboratory will develop a controlled multiple ricochet ballistic grill for the USMC EFV that minimizes the required vane thickness and associated pressure drop through the grille. Two-stage baffling of the incoming threat allows the flow direction to be modified while still ensuring at least three strikes and downward exiting fragments. Advanced high hardness Titanium and Stainless Steel alloys are used to tailor the ricochet angles of the threat projectiles, while maintaining integrity against corrosion degradation in the salt air and water environments. Low emissivity coatings on the metallic elements minimize the vehicle IR signature increments. The controlled ricochet design will allow reductions of at least 50 pound in each of the (250 lb.) current ballistic grilles aboard the EFV. During the Phase I project, Triton will fabricate and ballistic test samples of the projectile baffles to validate the threat protection performance, while C.S. Draper Laboratory will perform extensive CFD and thermal response tradeoffs on the strawman grille design to guide the grille design and validate throughput and thermal performance. During the Phase II Triton will fabricate a prototype ballistic grille for installation and operational testing aboard an EFV. |

| Title: | Development of Biological Obscurants |
| Abstract: | The DoD has funded a number of nanotechnology based obscurant projects. Recent studies have shown the potential health and environmental risk associated with nanoparticle exposures. Development of biologically based obscurants could eliminate these shortcomings by providing multi-spectral capabilities, environmental-friendly (i.e., biodegradable), non-pathogenic constituents and non-toxic by-products. GXI and Dr. James P. Chambers of the University of Texas at San Antonio propose to develop biological obscurants for battlefield applications based on the use of bacteriochlorophylls. In Phase I, GXI and Dr. Chambers will conduct spectroscopic investigations of bacteria containing bacteriochlorophyll b with tetrapyrrole pigments to demonstrate the feasibility of using chlorophyll compounds as obscurants. We will also investigate the use of combinatorial techniques to alter the protein microenvironment near the tetrapyrrole ring and thus tune the absorption spectra to provide multi-spectral capabilities. The rational for use of chlorophyll compounds as an obscurant is based on the broad range of spectral absorption using chlorophyll derivatives. Absorption peaks coincide well with specific areas of military interest including: (1) the visible range; (2) night vision ranges of 700 to 800 and 900 nm for 3rd generation imaging technology; and (3) the 1064 nm range for most smart bomb and missile laser guidance systems. |

| Title: | Shelf-Stable Red Phosphorus |
| Abstract: | Smoke-producing munitions such as mortars, smoke pots, and hand grenades are an important class of ordnance employed by the US military in both training and mission scenarios. These devices serve a number of vital functions including smoke screening for vision obscurance and marking of targets. A number of smoke-producing munitions used by the USMC rely upon red phosphorus (RP) to generate a smoke that provides screening in both the visible and IR spectra. Although RP performs exceptionally, its susceptibility to degradation during storage to form phosphine and other hazardous materials has risen concerns for personnel health. In this Phase I SBIR program, Infoscitex Corporation (IST) proposed to enable the continued use of RP through development of a novel coating system that will render it shelf-stable. IST will develop an inorganic coating system that will address shortcomings of previous attempts to stabilize RP, and will ensure that performance of existing smoke-producing munitions is maintained. |

| Title: | Replacement of Red Phosphorus in Smoke Producing Munitions |
| Abstract: | Future combat scenarios requires a red and/or white phosphorus alternative as a multi-role munitions filler for obscuring, screening, marking, incendiary and thermobaric applications. Currently, red and white phosphorus filled munitions are successfully being deployed in combat, especially in "shake and bake" missions in Fallujah. However, processing, deployment, storage and overall safety concerns primarily limit the utilization of red and white phosphorus. Especially when stored, phosphorus decomposes to phosphorus pentoxide and then phosphoric acid in moist environments. In lieu of safety concerns and cost ineffectiveness in producing red and white phosphorus, Powdermet Inc. proposes to use reactive fuel/oxidizer microcomposite obscurants with "nanolaminate" fuel/stabilizer/thermite coatings produced by Fluidized Bed Chemical Vapor Deposition (FBCVD) and fluoropolymer press coatings as a suitable/superior alternative for red and white phosphorus fillers for current and future munitions. The particle size, composition, and intimate mixing of fuel and oxidizer during spray drying, FBCVD, and fluoropolymer press coatings will yield favorable combustion and reaction rates in order to maximize smoke production, colored smoke production, exothermicity, and blast/expansion pressure. Complete characterization will be performed to ensure that the correct properties are achieved. |

| Title: | ADaptive Augmented Reality based Assistance System (ADARAS) |
| Abstract: | Augmented Reality (AR) has been proposed as a means of assisting technicians tasked with maintaining weapons platforms. Despite its various benefits, the effectiveness of AR as a means of improving performance dictates that the traditional challenges associated with scene recognition and information presentation be addressed. Hence, we propose to design and demonstrate the feasibility of the ADaptive Augmented Reality based Assistance System (ADARAS), which utilizes unique scene recognition capabilities coupled with customized information presentation techniques to significantly improve the troubleshooting capabilities of the junior maintainer. ADARAS uses intelligent agents to customize the information presented in AR space, which maximizes the utility and effectiveness of the presented information based on the cognitive limitations and learning capacity of the individual maintainer. The proposed system also encompasses unique scene recognition algorithms that jointly work to ensure that the maintainer's attention is allocated to the relevant problem space thereby maximizing the probability of success. |

| Abstract: | The Terrestrial Augmented Reality Maintenance Assistance (TARMA) will leverage Cybernet Systems existing Shipboard Wireless Maintenance System (SWMA), head mounted display systems, and gesture recognition software to create a portable computing platform for augmented-reality based vehicle maintenance. This system will use small, magnet-mounted, light emitting diodes (LEDs) beacons as reference points for the projection of schematics into the viewing region of the head mounted display. In addition to schematics and Interactive Electronic Technical Manuals (IETMs) and condition-based maintenance systems the head mounted display will present data from a suite of peripheral devices including digital multi-meters, bar code scanners, and RFID readers. Cybernet will also apply our gesture recognition system to the system's forward looking camera to provide a maintainer aptitude evaluation. This aptitude evaluation could potentially be used in level IV and V by IETMs to provide tailored maintenance specifications. Using the SWMA's existing collaboration suite our system will be able to provide remote support from subject matter experts to in-field maintainers. |

| Title: | Augmented Reality Maintenance System (ARMS) for Complex Military Assets |
| Abstract: | Currently, equipment maintenance requires highly trained individuals and is labor intensive, expensive and inefficient. The Marine Corps and DOD use written technical manuals and Interactive Electronic Technical Manuals (IETM) to direct technicians through complex maintenance procedures for land vehicles, radar systems, radio communications systems, and ground-based weapon systems. Recently, the internet has made it possible to retrieve relevant maintenance data more quickly using computer search programs. However, technical manuals are still time consuming and tedious to use, and substantial training is needed to extract the appropriate data, understand the technical details for troubleshooting defective components, and the performance of critical maintenance and repairs. RMD, in collaboration with Dr. Steven Feiner at Columbia University, proposes a revolutionary new technology for equipment maintenance based on Augmented Reality (AR). The AR-based maintenance system will guide the equipment maintainer through the entire maintenance process, from the identification of defective components to the detailed repair methodology and the functional test sequence. The Augmented Reality system will be graphics intensive and interactive, making it simple and highly intuitive to use. It will augment the abilities of the technician by providing the type of guidance normally associated with an expert human trainer. |

| Title: | Fused Reality(tm) Maintenance System |
| Abstract: | The solicitation for this topic stresses the need for alternative approaches to conducting equipment maintenance. A PC-based technology called Fused Reality(tm) created by Systems Technology Inc. (STI) currently employs live video capture, real-time video editing, and virtual environment simulation to enable the fusing of physical images into a virtual scene, which can then be moved within that scene. Fused Reality(tm) uses chromakey to identify areas of interest in the physical scene. One of the key innovations of the proposed Fused Reality Maintenance System (FRMS) is modifying Fused Reality(tm) to use machine vision for identifying real objects so that they can be fused into and moved within the virtual environment. Other novel innovations include the integration of novel 3D interfaces (such as image-based head tracking) with a 3D modeling software tool such as Solidworks, and using Solidworks to generate the virtual scene layer for use with Fused Reality(tm). In order to provide an integrated solution for the maintainer's challenges, the system will employ state-of-art technologies including: machine vision recognition, voice recognition, neural networks, and knowledge-based expert systems. Novel design in human-machine interface design will balance cognitive workload with task execution. Key issues pertaining to diagnostics, component replacement, and logistics are addressed. |

| Title: | Non-Line-of-Sight Coating Of Turbine Airfoils |
| Abstract: | Thermal barrier coatings (TBC) are desired to improve the durability of hot-section engine components. Currently, TBC top coats are applied onto turbine components using an electron beam physical vapor deposition (EB-PVD) process. A key drawback of this approach is that it can only effectively coat surfaces in the line-of-sight of the vapor source. The advent of advanced engine designs containing complex components with many hidden surfaces have resulted in a need for TBC deposition techniques which can effectively deposit high quality coatings onto the non line-of-sight (NLOS) regions of components. In this work, we will use novel coating techniques that increase the growth rate of TBC coatings in NLOS regions and also result in the required coating microstructure. The proposed Phase I effort will demonstrate the key performance attributes of the process by applying TBCs onto superalloy substrates aligned NLOS to the vapor source. This will lead to a follow-on Phase II program focused on using the new deposition process to apply TBC coatings onto real aircraft components having NLOS region. The end result will be process the can apply next generation TBC coatings onto a wider range of complex engine components in a cost effective manner. |

| Title: | Demonstration of Non-Line-of-Sight TBC |
| Abstract: | Advances in turbine materials resulting in high strength and lightweight metallic and ceramic components have allowed for high efficiency, high power density, compactness, and low emissions. Current technology turbine blades are comprised of single crystal nickel superalloys in combination with ceramic thermal barrier coatings (TBC). Typical TBC composition consists of an aluminum rich bond coat, thermally grown oxide (TGO), and yttria stabilized zirconia (YSZ). These coatings have limited durability and constrain peak engine temperatures due to non-uniform coating thickness and susceptibility to crack propagation. Non-uniformities within the thickness are caused by line-of-sight coating applications typical of current industry standards. To address these shortcomings, Mainstream will rely on its expertise in nano-technology and chemical vapor deposition techniques to demonstrate a non-line-of-sight method for producing a strain-tolerant thermal barrier coating. The Phase I effort will characterize the mechanical properties of the nanocomposite coating, demonstrate the feasibility of the inclusion of nanostructures within a ceramic matrix, and validate the strain tolerance via thermal fatigue and thermal shock experiments. |

| Title: | Non-Line-of-Sight Coating Of Turbine Airfoils |
| Abstract: | The current state-of-the-art techniques for thermal barrier coatings (TBCs) are typically line-of-sight. Therefore the achievable coating thickness distributions on complex shaped parts are limited and inconsistent. The geometry of the turbine airfoils is getting more complex with each design making the line-of-sight processes for TBC less desirable. UES Inc in collaboration with Penn State University proposes to design a hybrid hydrothermal-electrophoretic process as a non-line-of-sight technique for TBC. The feasibility of the proposed technique will be demonstrated in a laboratory environment. Durability of the TBC fabricated from the proposed technique will be evaluated and compared with the state-of-the-art TBC coating. In Phase II, a prototype hybrid hydrothermal-electrophoretic system and the related process capable of producing TBC coating on engine hardware will be developed. |

| Abstract: | The primary objective of Phase 1 is to establish a design baseline for a very high power and highly efficient GaN amplifier. Design objectives for the Class E/F power amplifier are to achieve 100 watts power output at >60% PAE over 405-450 MHz. Hittite will synthesize Class E, Class F and inverse class F and then select the optimum load and source networks to achieve highest reasonable efficiency. Hittite will use a very thermally conductive hybrid package. That packaging is a highly cost effective proven mass production packaging technology. Hittite will identify the optimum process for MMIC implementation of the amplifier, and then provide modeling results of the core technology demonstrating the RF, DC and thermal characteristics of the amplifier. From this selected MMIC core technology we will build and demonstrate a hybrid version of this amplifier. The hybrid version will use proven 50V GaN devices and a proven design approach. In the option Hittite will also design a high K dielectric power combiner, and the first iteration of the GaN 100 watt PA MMIC. Hittite has designed over 20 GaN PA's for numerous DOD customers demonstrating > 70% PAE GaN PA's. |

| Abstract: | Robust Analysis has pioneered the development of extremely efficient algorithms for radar signal processing in heavy-tailed clutter, based on cutting-edge numerical methods derived from the theory of stable distributions. Robust Analysis is the developer of STABLE, the first commercially available software library for stable data processing. STABLE incorporates a Signal Processing Toolbox with comprehensive filtering solutions for impulsive signals. This toolbox is at the core of one of our most important innovations: the stable matched filter. Although still preliminary, STABLE already has a Radar Systems Toolbox which incorporates a suite of stable matched filtering routines, and a battery of applications of these routines in SAR imaging and radar target detection. The goal of this SBIR is to extend the reach of the STABLE software and its Radar Systems Toolbox to provide a comprehensive industrial-quality solution for radar engineering in heavy-tailed environments. For Phase I, we will develop an adaptive version of the stable matched filter that ensures real-time applicability of the technology in real-life challenging scenarios of interest to the Navy. We will also develop speed optimizations that accelerate the algorithms and enable real-time performance. SAR and STAP applications of the technology will also be investigated. |

| Abstract: | Unmanned Aerial Systems are rapidly evolving in each of the armed services from their traditional Intelligence, Surveillance, and Reconnaissance missions to platforms with a mix of payloads and weapons. All indications are that this evolution will continue and the future of Fire Scout will include an assortment of weapons and other mission payloads. Each of these future integration programs would be time consuming and expensive if traditional acquisition and integration approaches from the era of manned aircraft were adopted. Torch Technologies, Inc. has partnered with General Dynamics Advanced Information Systems to propose a robust and credible approach to weapon and mission payload integration that is based on the Object Management Group (OMG) Model Driver ArchitectureT (MDA) Initiative. the Torch Team proposes a complete systems engineering approach that is based on the principles of MDA. It is a solution that separates functionality from architecture so that it can be maintained and reused, even across multiple architectures. It is a solution that will map the functionality to the platform processing architecture based on the Fire Scout Program Manager's safety, reliability, security, real-time and resource consumption requirements, and permit early and cost effective verification and validation that those requirements will be met. |

| Title: | Modeling Algorithms for Unmanned Aircraft/Weapons Management Systems |
| Abstract: | Current methodologies for integration of weapons on unmanned and manned aircraft platforms and the associated control software development/integration typically result in a lengthy and expensive integration process. Problems are frequently discovered in the hardware/software prototyping or flight test program phases, when they are difficult and expensive to fix and likely to result in significant program perturbations. Potential safety issues that were not forecast can also be encountered. Recent studies by both U.S. and NATO organizations have identified structured modeling technologies and processes (including the evolving Model Driven Architecturer, or MDAr, process supported by commercial industry) as having a high potential to significantly mitigate the identified problems, if appropriately adapted and incorporated into the platform avionics and weapon integration design approach. To support such a model-based process, flexible modeling algorithms for weapon control systems and associated weapon employment functionality need to be developed in languages such as the Architecture Analysis and Design Language (AADL) and Executable Unified Modeling Language (xUML). The effort proposed here would investigate the requirements and feasibility of a set of appropriate modeling algorithms for this purpose, and define a proposed approach for development and demonstration of prototype algorithms in a follow-on Phase II program. |

FTI's research adapts successful system-level prognostic and RCM technologies to installed electronics systems using data-derived statistical models that function with existing data sources and are easily extended to varying system configurations. The research will: * Maximize use of existing sensors, parameters and data sources from installed systems. * Create models of healthy systems using variances from optimum system conditions to detect incipient faults. * Identify the fault to failure progression and estimate component or system RUL. * Notify system users of fault detection, RUL and suggested action/areas of investigation This Phase I effort extends FTI's research into prognostic assessment of system health. Phase II will demonstrate prototypes of the models developed during Phase I and will identify limitations and areas requiring investigation in applying the technology to specific electronic system configurations. |

| Abstract: | Prognostics and health management technologies are critical for detecting impending equipment failures and enabling a proactive decision process for maintaining or replacing components before actual failures occur. This capability is particularly critical to the Joint Strike Fighter given the goals for high affordability and mission readiness. Achieving the gains in maintenance decision making, safety, system availability, productivity, and cost savings, depends on the PHM system's ability to predict accurately the remaining useful life of the aircraft mission systems at any time. This effort investigates the development of advanced prognostic models to enable the predictive capability of the JSF PHM system. The effort considers the application of real-time, sensory- updated, residual life based models for estimating and predicting the remaining useful life of the JSF Communication, Navigation and Identification systems. The effort researches and characterizes the detectable impeding faults, and the physical phenomena, of the system and component degradation processes. The expected patterns in the sensory information and the techniques required to model the evolution of the component degradation process, in order to predict the remaining useful life of a system, are identified. A system definition, capability implementation plan, and a proof-of-concept demonstration of the approach are part of this effort. |

| Abstract: | Ridgetop will create algorithms and models for Prognostics/Health Management (PHM) on radio-frequency (RF) components used in Communication, Navigation, and Intelligence (CNI) systems. A key focus of this work is adaptation of proven time-domain statistic analysis techniques - Multivariate State Estimation Technique (MSET) and Sequential Probability Ratio Test (SPRT) - to the frequency domain, exploiting the increased sensitivity and robustness of the statistical approach with the computational economy achieved with Fourier-transform or frequency-space algorithms. These models will be proven on representative CNI hardware chosen by Ridgetop's Prime Contractor Partner (Raytheon) with input from the JSF Program Office. The chosen hardware will have a history of high failure rates and intermittent faults, and the prognostic models will be driven by existing parameters and measurands. Ridgetop's proactive IRAD for this proposal indicates that subject components can be chosen which represent both legacy (ageing aircraft) and emerging technology, to maximize return-on-investment (ROI) to the warfighting customer. An optional effort will focus on one complex, high-failure rate CNI component such as the Traveling-Wave Tube (TWT). Ridgetop's proposed work plan includes demonstrated detection of intermittents which complicate the diagnosis of faults and prediction of remaining useful life for critical aircraft systems. |

| Title: | Compact Magnetic Detection Set (CMDS) for Air Antisubmarine Warfare (ASW) and Land-Based Use |
| Abstract: | This SBIR Phase I proposal describes the development of a conceptual design for a Compact Magnetic Detection Set (CMDS) for air ASW. The CMDS laser magnetometer is an innovative light-weight, compact, low-power, high-sensitivity instrument capable of measuring scalar DC and ELF magnetic fields with sensitivity better than 0.3 pT/?aHz in the frequency interval 0.01-100 Hz. A design goal of the CMDS is to reduce the system volume, weight and power by a factor of two with respect to DT-704/ASQ-233 system parameters. The CMDS is intended for use on UAVs (vertical take-off and fixed wing) employed for shallow water ASW and land-based target detection such as buried weapons caches and IEDs. An approach to reduce system size and weight is the use of Optically-driven Spin Precession (OSP) instead of conventional Magnetically-driven Spin Precession (MSP) to induce and observe magnetic resonance in the helium cell. OSP technology is attractive for a compact system because it eliminates the need for resonance drive coils and reduces the number of cells required for omni-directional operation. An OSP single-cell digital locked-oscillator scalar magnetometer was demonstrated for the first time under a recent NASA Phase I Project. The Phase I effort will include developing the CMDS specifications that will achieve the size, weight, power and performance requirements, and evaluating the applicability of CMDS to small UAV/VTUAVs and manned ASW platforms. The Phase II effort will involve fabrication of a CMDS laboratory breadboard based on the Phase I design. |

| Title: | Antenna to Antenna Coupling and Electromagnetic Interference (EMI) Tool for Air Platforms. |
| Abstract: | One of the most important problems encountered in an electromagnetic environment is that of providing compatibility between radiating and receiving RF equipment within the environment. This problem is a type of EMI and the goal of RF system designers and analysts is to achieve EMC where no interference problems exist between the various RF systems. The cost of providing numerous modifications to operational systems and the losses in efficiency resulting from the presence of interference represents a serious problem to numerous military and commercial organizations. Our team proposes to develop a software tool named Electromagnetic Interference Toolkit (EMIT) for predicting interference between radiating and receiving RF systems. The tool will consist of a graphical user interface (GUI) and underlying computational engines. The GUI (iEMIT) will pass user specified inputs to the computational engine (EMIT), will provide visualization of data, and will interface with a full wave solver for the generation of coupling data. During the Phase I, we will develop the architecture and implementation plan for the EMIT software, develop proof of concept modules for the computational engines, and validate those modules. The Phase II will focus on developing a GUI and implementing the proof-of-concept codes developed under the Phase I as robust engineering codes. |

| Title: | Variable Color Ratio Window for IR Simulator Source |
| Abstract: | Agiltron, Inc proposes a dynamic color ratio window of IR simulator source array for the open-air test and evaluation of missile warning and directional infrared counter measurements. The proposed device is innovative to utilize the variable IR absorption of window approach, achieving the desired performances by effectively changing the transmission coefficients in the interest IR wavebands, such as (3.8~4.1ŸYm) and (4.5~4.7ŸYm). This windowÝs functionalities will enrich the major performances of the current open-air test IR source systems. The proposed IR window device is in standalone, enabling the operation flexibly with the present and under developing open-air test IR sources. This device offers intrinsic advantages of color ratio change in speed, large dynamic range, capability of operation in the outdoor severe environment, and great potential of profiling multiple spectrum bands. In the Phase I program, we will demonstrate a functional prototype of dynamic IR absorption type attenuation window with fast response and continuous ratio change. This experimental result will define our innovative system design concept, leading to a fully functional system in Phase II. |

| Title: | Dynamic Color Ratio Infrared Simulator Source |
| Abstract: | Typical threat missile signatures have a definitive characteristic color ratio signature. Infrared (IR) missile warning systems currently under development use two-color processing to discriminate missile threat signatures from non-threat signatures. It is necessary to have a dynamic color ratio capability to more realistically simulate various threat missile signatures. K Lab Corporation proposes to develop a robust IR simulator source that provides continuum spectrum between 2-5 micrometer, with controllable power intensities over the entire MIR radiant band, over one narrow pre-selected wavelength band, as well as the dynamic color ratio between two selectable wavelength bands. This IR source can be easily scaled up and integrated into an open-air surface-to-air missile simulator system. |

| Title: | Two Color Dynamic Scene Generator |
| Abstract: | OPTRA proposes the development of a fieldable two-color infrared (IR) source simulator based on fused projected images of two digital micromirror devices (DMDs), one for each IR spectral band. Our approach employs a broadband thermal IR source with a series of spectral filters to flood the DMDs with characteristic "red spike" and "blue spike" IR energy, respectively. The relative intensities of the two spectral bands are controlled through the duty cycle of the "on" image reflected by each DMD. We fuse the two simulated images and project the composite with a telescope of aperture diameter chosen to meet the radiant intensity requirements of this application. The overall approach offers a realistic IR source image of characteristic spectral, temporal, and radiant intensity properties of an actual missile plume. |

| Title: | Dynamic Color Ratio Infrared Simulator Source |
| Abstract: | The Naval Air Warfare Center (NAWC), Weapons Division, China Lake, has a requirement to develop a Dynamic Color Ratio Infrared Simulator (DCR-IRS) source for open-air test and evaluation (T&E) of missile warning and countermeasures systems. "Two-color" IR sensors employed by missile warning systems are used to discriminate against false threats by examining the "color ratio" of the signature, more specifically, the relative power in two mid-IR bands. Since the spectral (mid-IR) signatures of missile plumes can change significantly during the missile flight, an IR simulation with a dynamic color ratio capability is required for realistic T&E of these two-color missile warning systems. Technology Service Corporation (TSC) is proposing three innovative solutions to the DCR-IRS requirement. The primary solution, based on technology employed in the Infrared Simulator and Target Array (ISTAR) system at NAWC, uses flame sources configured to dynamically control the power levels in two mid-IR bands. Additional solutions use lasers and lamps to generate the required spectral signature. Under Phase I, TSC will investigate these solutions and others, performing tradeoff studies to establish feasibility; then, in Phase II, TSC will develop and demonstrate a proof-of-concept system that will provide ISTAR with an initial DCR-IRS capability. |

| Title: | Sonobuoy System and Concept of Operations for Time-Reversal-Based Target Detection |
| Abstract: | Existing multistatic airborne ASW systems require high power sources and are unable exploit the significant forward scattering target strengths due to the blinding presence of the direct blast. Time reversal (TR) is a recent method for focusing acoustic energy at a point using a pair of vertical line transducer arrays and offers the opportunity to exploit forward scattering from submarines. TR focusing can provide a measure of propagation channel stability, which provides a means for determining when the medium is disrupted as would occur when a scatterer such as a submarine passes between the two arrays. Moreover, because there is significant spatio-temporal focusing gain to be had with TR, there exists the opportunity to use lower power transmissions. Here we propose to determine the feasibility of a TR sonobuoy system for airborne ASW in the frequency band of a DICASS (AN/SSQ-62) sonobuoy and using vertical line arrays similar in dimension to a VLAD (AN/SSQ-77) sonobuoy. Operating at DICASS frequencies allows for achievable array apertures, exploits extremely high forward target strengths (> 50 dB) and improves the sensitivity of the TR. Post Phase I efforts would include implementing modifications to existing sonobuoy hardware for in-water demonstrations. |

| Title: | Catapult Elongation Sensor |
| Abstract: | Average catapult power cylinder temperature is currently inferred from elongation of the cylinder row, as measured by comparing the position of a pointer attached to the vented power cylinder relative to a graduated scale located on the flight deck. The Bow Safety Observer (BSO) must repeatedly take this reading from the flight deck during operations and then communicate the elongation to the Integrated Catapult Control Station (ICCS) or Central Charging Panel (CCP) to properly set catapult controls. Creare proposes to develop an automated system to measure the power cylinder elongation to reduce workload and safety risk for flight deck personnel and improve launch performance. This device will automatically provide a high-resolution, deck-temperature-corrected measurement to the ICCS/CCP and will maintain the existing pointer as a manual backup. During Phase I, we will evaluate several promising contact and non-contact measurement methods and design and fabricate prototypes of the most promising approaches. Phase I testing will help identify issues with possible approaches and synthesize solutions to address these issues. Phase I is intended to select the optimal approach, and Phase II will include the detailed development of a prototype that can be tested on a carrier. |

| Title: | Inductive Catapult Elongation (ICE) smart sensor for Catapult Elongation Sensing |
| Abstract: | The current technique for measurement of aircraft carrier catapult thermal elongation, while effective, is manpower intensive, slowly communicated, and potentially dangerous. Physical Sciences Inc. (PSI) proposes a powerful new enabling technology for sensing linear displacement of the catapult end automatically using a non-contacting, inductive technique. This technique uses the physical phenomenon of mutual inductance between an engineered conductive target and a planar array of conductors, both encapsulated in steel housings to form a sensor module. The sensor module outputs an electrical reading of displacement to a remote readout and display circuitry. To achieve this, PSI is teaming with OEM sensor provider Zettlex Limited, a world leader in monolithic, encapsulated, non-contact position sensing. The proposed measurement technique requires no moving parts, including bearings or couplings, no precise mounting, and no hands-on calibration. The result is an ideal linear displacement measurement for extreme shock and temperature environments where mechanical tolerances are difficult to maintain. |

| Abstract: | Visidyne proposes a novel fiber optic sensor to measure the elongation of steam catapults used by the Navy for launching aircraft. The sensor, originally developed by Visidyne for use in environments found in and around jet aircraft engines, is completely passive at the measurement point and so can operate in very harsh, high temperature environments. There are no electronics at the measurement head to limit high temperature operation. The stimulus and signal readout are coupled to the measurement head via optical fibers which can be tens of meters or longer, allowing remote operation with complete immunity to electromagnetic interference (EMI). Repeatability and absolute accuracy on the order of a hundred micrometers and resolution of better than ten micrometers is achievable. |

| Title: | Reactive Missile Plume Simulator for Open-Air Testing |
| Abstract: | The Naval Air Warfare Center (NAWC), Weapons Division, China Lake, has a requirement to develop a Reactive Missile Plume Simulator (RMPS) for open-air test and evaluation (T&E) of infrared (IR) missile warning and countermeasures systems. Adequate evaluation of Directional Infrared Countermeasures (DIRCM) requires that missile plume signatures be simulated for both jammed and non-jammed missile conditions. The high DIRCM IR tracker resolution dictates a continuous spatial plume simulation. Technology Service Corporation (TSC) is proposing two innovative solutions to the RMPS requirement. The primary solution, based on technology employed in the Infrared Simulator and Target Array (ISTAR) system at NAWC, uses extended infrared sources configured end to end to define jammed missile trajectories. The sources (10 meters in length) are instrumented with detectors for IR bands I, II, and IV to monitor DIRCM. A secondary solution, with potential for high simulation fidelity and flexibility, uses a remotely-controlled Organic Air Vehicle with a compact IR source and IR band I, II, and IV detectors. Under Phase I, TSC will investigate these solutions and others, performing tradeoff studies to establish feasibility; then, in Phase II, TSC will develop and demonstrate a proof-of-concept system that will provide ISTAR with an initial RMPS capability. |

| Title: | Recognition of High-Range-Resolution (HRR) Profile Signatures of Moving Ground Targets for Combat Identification (CID) |
| Abstract: | Limited success of current High Range Resolution (HRR) Aided Target Recognition (AiTR) approaches are largely due to the following shortcomings: 1) the heavy reliance on HRR profile features that are susceptible to measured HRR profile variability and 2) the attempt to declare targets at the highest level of specificity (e.g. T-72 instead of Tank) in all cases. The first shortcoming limits HRR AiTR performance because measured HRR profiles are susceptible to measurement noise, translational range migration (TRM), rotational range migration (RRM), speckle reflection, and self-occlusion. As a result, current approaches that use such HRR features cannot confidently discriminate between many target types. The second shortcoming aggravates the first by attempting to make highly specific target recognition declarations among ambiguous target types that typically exhibit only subtle differences in HRR profile features. In the proposed solution, Temporal Feature Correlation with Hierarchical Reasoning (TFC-HR), these shortcomings are overcome by employing: 1) HRR profile features that are robust to real-world sources of HRR profile variability and 2) hierarchical feature clustering that allows for target recognition at varying levels of specificity. |

| Title: | Recognition of High-Range-Resolution (HRR) Profile Signatures of Moving Ground Targets for Combat Identification (CID) |
| Abstract: | The objective of this proposal is to demonstrate the advantages of using a Hierarchical Hidden Markov Model for Aided Target Recognition of High Range Resolution (HRR) radar. A Hidden Markov Model (HMM) based technique has been previously shown to provide aided recognition of HRR with high probability of correct identification and low probability of error. This proposal extends current HMM techniques by utilizing a generalized HMM, known as the Hierarchical Hidden Markov Model, with several attractive properties not found in classic HMMs - in particular superior ability to learn the different stochastic levels and length scales present in the structure of the target features. One key difficulty in the application of any HMM is parameter estimation. The unknown parameters are typically point-estimated in a Maximum A Posterior (MAP) or Maximum Likelihood (ML) sense using an Expectation Maximization algorithm. We propose to utilize a Variational Bayes (VB) algorithm that does not generate a point estimate for the parameters but an approximation to the full posterior of the model parameters. The VB technique has shown in many applications to be less sensitive to overfitting and better-suited for active learning; the VB solution also allows one to perform model selection, here concerning the appropriate number of HMM states. |

| Abstract: | We propose to design and implement algorithms for the remapping of scenes from one or more existing views. The routines to be developed will present realistic virtual views from any desired direction. Realism of the views increases with additional information about the cameras, scene and with the number of views. We show that realistic reprojections do not require multiple source views if given information about the camera that is typically available with imagery obtained from an airborne platform. Methods for presenting the optimal remapping given any level of information are presented. The methods working from the least information are also the fastest, and real-time processing of high resolution video data streams can easily be accomplished with small, lightweight systems. |

| Abstract: | Recent enabling technologies are allowing Navy F18 strike aircraft and UAVs to work together fist-in-glove for close-quarters urban combat. Our proposal for TV2 (Targeting Video from VIVID) ties together these assets ever more effectively. TV2 remaps UAV target imagery into targeting imagery as will be seen from the F18's targeting pod. This speeds F18 visual cueing and target confirmation. Aerodyne's innovative approach side-steps need for online signature code computations, enabling TV2 real-time execution on COTS hardware, yet producing high-fidelity imagery. Two key modules comprise TV2. (1) View extrapolation, involving inference of target geometry, represents view-dependent illumination and shadowing effects not possible from image-warping or conventional IBR. (2) Atmospheric correction employs pre-computed physics, correcting color balance and saturation loss without needing non-portable hardware acceleration. Our Phase 1 effort will confirm the TV2 and transit case processor (TCP) ConOps with NAVAIR. Employing focused algorithm prototyping and testing, we will determine the best candidate view extrapolation algorithm and validate our pre-computed atmospheric correction scheme, all using efficient tools and methodologies in-hand. In Phase 2 we will fully implement and integrate TV2 with the VIVID algorithms on the TCP. The delivered TCP will be ready for Phase 3 T&E demonstration and subsequent operational transition. |

| Abstract: | UAV to target-platform handoff requires the capability to remap imagery to conditions of the target platform to enable accurate identification (ID). SET proposes to design, demonstrate feasibility, and implement an operational system to provide variable remapping of airborne imagery. We propose to evaluate novel view synthesis solutions for instances where targets lie predominantly on a dominant plane as well as those for which non-planar characteristics are extractable. Rapid methods for both cases using computed homographies, properties of the image acquisition scenario, and platform metadata will be analyzed for effectiveness in terms of view synthesis and real-time implementation. We will analyze performance with respect to system parameters including range and perspective uncertainty, reliability of the synthesized view, latency effects and the overall enhancement of confirmatory ID (CID) due to the view synthesis. The system design incorporates correction for auxiliary conditions, including atmospheric and sensor characteristics, to provide target imagery that accurately depicts the expected view from the targeting platform. Feasibility of the proposed approach will be demonstrated in Phase I, with Phase II focusing on the development of a fully evaluated prototype integrated within the Video Verification of Identity (VIVID) platform. |

| Title: | Whale Search Radar |
| Abstract: | Marine mammals are often found in areas where US Navy ASW test operations are carried out. Several events have raised levels of concern that sonar emission could be causing deleterious impacts on marine mammals. For instance, in March of 2000, a mass stranding of beaked whales [NOAA report Dec 20, 2001] occurred coincident with an exercise of U.S. Navy ships operating mid-frequency sonar around the Bahamas. Other similar events have occurred. The solicitation objective is to detect, classify, and localize whales and other contacts in an ASW test range in a variety of sea-states. This will be accomplished by the Adaptive Methods and SSR Engineering team with a combination of commercial low-cost radar and other sensors, tracking and classification software, and operator controls and display. A system engineering and R&D development approach is given, with recommendations for work to be performance in Phase I through Phase III. A test data collection system and approach is described that uses available assets. Key R&D algorithms required are identified and developed. |

| Abstract: | Current ASW testing is often limited by the presence of marine mammals on ASW test ranges. The solicitation suggests the development of a radar system and associated algorithms to detect breaching whales in various sea states. The detection would then be handed off to an EO system for verification, classification, etc. The RADAR system must be able to discriminate the marine mammal blow or breach from open ocean breaking waves. The EO system, once queued must be able to reacquire the animal for verification and classification. This proposal suggests using an EO system that would not only be used as a verification/classification system but would also be used to detect non breaching submerged marine mammals in all sea states as well as breaching animals in high sea states. This EO system is combined with a modified COTS radar system which uses a single transmitter and two receivers. We suggest exploiting the phase difference between the two receivers to discriminate blows from open ocean breaking waves. |
