Title:High Efficiency, Low Current, Switching Power Supply
Abstract:The Phase I program will demonstrate, at hardware level, a prototype digital dc-dc converter that is subcompact and very high efficiency converter technology. It introduces advantages of very low weight/volume/component count, very low output ripple voltage, voltage isolation, negligible RFI/EMI and non-flammability. In Phase I a very high efficiency digital ceramic (programmable output) low power converter prototype suitable for military equipment insertion will be demonstrated that can be implemented well within the desired volumetric constraint with a minimum of external passive components. The digital subcompact hardware dc-dc converter prototype will feature a digitally selectable voltage output (e.g. 2V - 6V); software battery monitoring and extremely low output ripple voltage characteristics. In Phase I Extension the new concept of digital dc- dc transformer/converter will be demonstrated that is capable of near 100% converter efficiency operation.

Title:Monolithic Ultra-High Efficiency DC-DC Converter
Abstract:Ridgetop Group, Inc. will develop a unique and innovative capacitance-only switching power converter with efficiencies over 99%. Power efficiency and battery life are vital concerns for the modern war-fighters who rely on portable electronic technology to enhance their effectiveness. Batteries used for radios, rangefinders, and night vision equipment contribute weight and reduce net carrying capacity. The proposed monolithically integrated power supply unit will alleviate this burden by providing ultra-high efficiency DC-DC conversion in a small package. Weight reductions will be achieved in required batteries and conversion electronics. Achieving small package size and efficiencies above 95% are extreme challenges for a conventional inductive switch-mode power supply. Ridgetop will develop a capacitive-only switching supply based on a charge-pump and charge capacitor approach. Recent advances in semiconductor processing, including low-power, high-voltage devices, will enable new designs to achieve efficiencies greater than 99%.

Title:Security extensions to the JTAG standard
Abstract:JTAG provides full and open access to the internal state of all JTAG-enabled components of a system under test. While this capability is critical to the development and system maintenance processes, it is a backdoor into all JTAG-enabled system components. This project seeks to eliminate/secure the JTAG backdoor by developing secure extensions to the JTAG standard; these secure extensions will control access to the JTAG boundary scan ports on all digital ICs and systems including commercial microprocessors, FPGAs, and ASICs.

Title:High-Speed Surface Measurement Device
Abstract:Weather conditions that may affect the design of missile radomes, windows and leading edges include the presence of rain, snow/sleet in the atmosphere and sand during missile flight trajectory. The Tri-Service Agencies Weather Encounter Advisory Group led by AMRDEC is organizing tests to study the detailed fracture mechanics of brittle ceramics radome material in free flight. In this proposed work we will develop a dynamic holographic interferometry technique to measure dynamic surface deformations of a fast moving missile. Specifically, we will analyze and evaluate different optical methods, and design experimental holographic interferometry set-ups for measuring deformations of a missile radome moving in a rain field or in a sand cloud. We will be using combined approaches of digital holography and analog holography. Initially, we plan to use CW analog holographic schemes with a controlled shutter that will allow performing analog holographic interferometry using thermoplastic holocamera or photorefractive materials. Also, parallel methods using digital holography and digital holographic interferometry will be used. Finally, we will develop numerical models that analyze analog holographic interference patterns and digital holographic interferometry results to infer changes in surface map of the radome due to deformations.

Title:Holographic Light-in-Flight Interferometric Camera
Abstract:To address the Army need for high-speed measurement technique for weather impact damage assessment of projectile IR domes and radomes, Physical Optics Corporation (POC) proposes to develop a new Holographic Light-in-Flight Interferometric Camera (HOLIFIC) three-dimensional imaging sensor based on short-pulse dynamic holographic recording of a projectile in flight. The innovation in the integration of light-in-flight holography with the short-pulse holographic interferometry will enable the proposed sensor to provide an optical inspection of surface roughness and deformation of a high- speed object. As a result, this system offers simultaneous measurement of surface profile and deformation over a wide range, instantaneous (light-speed) recording, high- resolution, low-noise images, and full-field 3D surface profile. The holographic 3D image recording and interferometry will be in real time using an erasable permanently placed holographic recording medium in a ruggedized camera system. In Phase I, POC will design a HOLIFIC sensor, analyze its performance, and demonstrate the proof-of-concept by laboratory experiments. In Phase II, POC will fabricate a full-scale, HOLIFIC system and integrate it with data collection, 3D reconstruction and deformation analysis software. The prototype can be produced at relatively low cost, compared with high-speed CCD- based system, and will require a minimal setup and calibration time.

Title:Solid State Infrared Flare
Abstract:The use of night vision equipment on the battlefield is a well documented success, and under some conditions an infrared flare may enhance this advantage. Currently, US armed services use the M-278 Infrared flare rocket to this end. The objective of this effort is the development of a replacement for the M-278 Infrared Flare using LED technology. The operational difficulties of the present system are related to the poorly controlled chemical combustion nature of the source. A solid state LED-based technology upgrade is ideal as it does not generate high internal temperatures, has high reliability, and can be engineered to radiate no energy outside the desired band (700-1100 nm). The Infrared LED flare system will be comprised of an energy storage system, control electronics, power regulation, cooling system, LED emitter array, beam forming optics, and mechanical support envelope. LED testing will be performed to drive devices into the extreme high output regimes, which are atypical of most LED applications, while measuring photometric, distribution and lifetime data. The requirements, possible solutions and integration will be investigated for the optical, power, thermal, and control systems.

Title:Semiconductor Laser Packaging for Infrared Flares
Abstract:Flares are routinely used for battlefield illumination or for identification of hazards and landing strips. Visible light flares are simple in concept and execution, but have the disadvantage of being easily visible by anyone within visual range. Infrared flares enable the covert use of illumination, utilizing the advantage of modern Night Vision Goggles and can help enable today''''s war fighter to operate in the dark. In this proposal is outlined a design approach and preliminary systems analysis for an infrared laser diode based infrared flare system. Laser diode devices offer the highest efficiency and highest optical power density of any semiconductor based light source. nLIGHT''''s design capabilities for MIL SPEC laser diode packages, electronics, battery packs, and mechanical housings enable us to be highly confident that the presented design will satisfy the systems performance and cost requirements.

Title:A Compact Solid State Infrared Flare
Abstract:In this Phase I SBIR proposal Physical Sciences Inc (PSI) outlines the development a solid- state emitter package to replace the propellant based candle of the M278 Infrared flare. Propellant combustion in the current candle technology is unsteady, resulting in variations in the illumination intensity and also produces a visible signature that limits it usefulness in covert activities. The proposed flare technology will use solid-state components (Light Emitting Diodes or laser diodes) to generate Infrared illumination that will overcome these limitations of candle illumination. In the Phase I, PSI will develop a prototype design for the solid-state emitter package that is compatible with the current dimensions and weight of the M278 candle. The design process will include: 1) Emitter component characterization and selection, 2) optical system design to combine the output of multiple emitters to achieve the specified output radiance intensity (250 W/sr), 3) Evaluation and selection of a power system to drive the emitters and control circuitry and 4) Preliminary mechanical design that integrates these components. In Phase II the prototype will be built and tested, both in the laboratory and in the field.

Title:Solid State Infrared Flare
Abstract:The Army and other services use the M278 Infrared flare rocket that uses an illuminant candle to provide illumination compatible with night vision gear. Recent advances in solid state lighting offer the potential to replace the burning candle with a solid state illumination source. Princeton Optronics proposes an approach using a newly developed technology of VCSELs which offer many advantages over alternative approaches for illumination application. In phase I, we would conduct a feasibility study on our approach to providing a solid state replacement for the candle in the flare rocket. The study would include a detailed analysis of the approach including electronics, optics, and power. Operating alternatives, such as high speed pulsing, would also be investigated. Limited destructive bench tests of the VCSEL arrays to drive them into the extreme high output regimes while measuring photometric and lifetime data would be performed. By the end of Phase I we would have a proposed design for a solid state replacement for the infrared candle meeting the Army specifications. In phase I, we would also build an early prototype version of the package which can be tested by Army before the end of the phase I. The first build will use one of our VCSEL arrays of >200W of power at 976nm. In phase II, we would develop a benchtop demonstration prototype with a form factor of the solid state infrared flare. Measurement of the optical, electrical, and lifetime characteristics of the prototype would be conducted. Experiments to show that the prototype design would survive the shock environments of the M278 rocket would also be performed. In Phase III, we would finalize the design for production of the solid state flare replacement. Live fire demonstrations would be conducted in phase III.

Abstract:The Techshot Solid State Infrared Flare (SS IR Flare) will utilize existing high quality, commercial-off-the-shelf infrared LEDs to produce the required spectral output for use as a flare rocket providing illumination compatible with night vision gear. Powered by high current batteries, the physical configuration or form factor of the current launchers and flare rockets will remain unchanged. Techshot''s experience in developing both LED and power management systems for harsh environments comes to play as this specific project targets a reliable, repeatable design that ensures IR illumination is provided to the soldier as necessary to meet battlefield mission objectives.

Title:Polarimetric Sensor for Air-to-Surface Missile Systems
Abstract:Polarimetric imaging is a form of remote sensing that measures the relative intensity of the polarized components of reflected radiation from natural sources in an uncontrolled environment. In a natural scene, the majority of photons are randomly polarized. However, polarization can be induced by reflection off planar surfaces. This is particularly useful for detecting reflection from machined (man-made) surfaces. Polarization is also induced in an object’s self-emitted (thermal) radiation. Polarization information has been demonstrated to discriminate targets/objects from camouflage and clutter. Additionally, it has been shown that partially buried land mines can be discriminated by the polarization content of their thermal self-emission. This proposal describes a unique polarimetric device that, when incorporated into an imaging camera, will produce two orthogonally polarized images from a single focal plane in wavebands spanning the visible through the long wave infrared. Furthermore, this device is non- lossy and extremely compact. Bodkin Design and Engineering, LLC (BD&E) specializes in the development of compact thermal imaging cameras with zoom capabilities, miniature hyperspectral and multi-spectral imagers. We will develop and demonstrate a LWIR polarimetric imager under the Phase I contract, and incorporate it into a compact multiband camera capturing simultaneous video in the MWIR and LWIR in Phase II.

Title:Polarimetric Sensor for Air-to-Surface Missile Systems
Abstract:Polarization imaging holds promise for providing significant improvements in contrast and background clutter rejection in a number of target detection and discrimination applications. In several recent development efforts, it has been demonstrated that manmade objects have a significantly stronger polarization signal than natural backgrounds resulting in good contrast that complements the conventionally imaged infrared signature. However, the experimental polarimetric systems which have produced these data sets frequently require long data acquisition times which result in artifacts in the polarization imagery due to platform or target motion, or involve very large hardware packages not appropriate for an EO seeker system. Polaris Sensor Technologies, Inc proposes a comprehensive design trade-off study which considers all existing and emerging polarimetric architectures to determine an optimal design for a seeker imaging polarimeter. Established models will be used to determine the optimal waveband(s) of operation. MWIR, LWIR and MWIR/LWIR bands will be considered. A concept design of the seeker imaging polarimeter will be developed based on the design trade-study output. A Phase I Option would provide a detailed system design including optical, mechanical and electrical designs.

Title:Missile Interceptor Base Flow Simulation
Abstract:The program focuses on turbulence modeling enhancements for predicting hypersonic interceptor base flows, using existing benchmark data sets. Unified kε and algebraic stress (EASM) turbulence models, shown to adequately simulate fundamental high-speed jet data sets and now being validated with PIV data sets in a NASA Marshall program focused on baseflows, will be used. Complimentary Large Eddy Simulations (LES) will provide additional turbulence statistics that are not readily/reliably measured. The data will support enhancements to the CRAFT Tech unified k-ε turbulence model. The impact of employing a variable turbulent Prandtl and Schmidt number methodology, based on a two-equation scalar variance framework, will be considered for reacting and non-reacting base flows. The effort will lead to extended validation of enhanced turbulence modeling tools, increased reliability of base drag & heat flux predictions and fills a major gap at the US Army by improving upon base region simulation capabilities required for design of hypersonic interceptors. The program will also conduct initial planning for acquisition of “high-quality” baseflow data in the 12”X12” tunnel at the National Center for Physical Acoustics (NCPA), utilizing non-intrusive diagnostics.

Title:Investigation of Supersonic and Hypersonic Missile Interceptor Base Flows Using an Advanced Computational Framework
Abstract:A computational investigation of missile interceptor base flows in a supersonic/hypersonic application is proposed. High-fidelity three-dimensional simulations will be conducted using the proprietary framework Rocstar. The computational framework includes a compressible flow solver with advanced LES turbulence models and has flexibility sufficient to investigate a variety of base flow configurations under widely varying conditions. As a feasibility study for Rocstar, in Phase I we propose validated simulations for the flow past the cylindrical blunt afterbody configuration of Herrin and Dutton (1994) at Mach number of 2.5. In the Option period, we will develop a validation matrix, including a variety of geometries, for implementation during Phase II. We will also execute a simulation of the boat-tailed geometry. Professor J. Craig Dutton will serve as technical advisor to IllinoisRocstar on the SBIR project. The overall goal of this work is to develop, validate, and commercialize a numerical tool suitable for design and analysis. The code should accurately predict supersonic and hypersonic base flow characteristics to within ±5%, especially pressure and velocity data. At the conclusion of Phase I and the Option, we will have completed a study assessing Rocstar capabilities, compared two well-known afterbody geometries, and assembled a set of validation cases to direct and extend Rocstar for turbulent base flow.

Title:Metallic Grid Application for Green Ceramic Domes
Abstract:Transparent domes for multimode seeker technology with integrated fine metal grid for EMI shielding are currently being developed. Specific line width and spacing requirements for the embedded metallic grids in the domes significantly limit the available methods for fabrication. A potential approach to producing these structures is by applying a metallic grid pattern to the green dome blank, and then adding a second green layer of the same material over the grid. When the green blank is fired, the metal grid pattern sinters together into a continuous metal pattern at the same time that the ceramic layers are sintering together into a dense ceramic. We propose herein to develop a direct write grid application method, suitable to achieve the electrical requirements for the EMI shielding. The proposed method will overcome the prior issues by providing opportunities for a wide conductor material choice, as well as variable line thickness capability. Our proposed efforts build on prior and current experience with direct write methods that have been, or are being evaluated for this application. Gridded coupons and partial domes will be demonstrated in Phase I. A fully gridded 7” hemispherical dome will be produced by the end of the Phase I Option.

Title:Conformal Metal Grid Patterning for Green Spinel Domes
Abstract:Soft lithography is an inexpensive and fast method for applying micropatterned structures to both flat and nonplanar substrates. TA&T leverages multiple soft lithographic processing steps to pattern co-fireable refractory metal grid on spinel dome windows for electromagnetic interference (EMI) filtering purposes. In addition to the overall curvature of a green ceramic dome, the surface roughness poses difficulties that preclude many other techniques for applying high fidelity features to a surface. The proposed approach overcomes the technical issues by forming the conductive material grid pattern on a transfer film that can be integrated into the ceramic production process. A micromolding technique which infiltrates a photocurable resin formulated with metal loading into channels which define the grid dimensions is developed to pattern on the film. The complete system of inorganics and organics necessary for the gridding and transparent ceramic production is considered for compatibility. The resulting grid is expected to have low sheet resistance for high EMI shielding performance.

Title:Low-Cost Method for Metal Nano-Coating of Anisotropic Carbon Fibers
Abstract:Presently, there is a pressing need from U.S. Army in developing metal-coated carbon fibers, which will be used as the payload for the Joint Program Manager (JPM) microwave obscuration program because they are excellent attenuators in the microwave region of the electromagnetic spectrum. The metal coatings around carbon fibers are required to be highly conductive, less than 50 nm, and simultaneously can be produced cost-effectively. However, there is not a cost-effective processing method available that is capable of depositing a thin metal coatings less than 50 nm around carbon fibers. Therefore, in this proposed research program, Aegis technology will: (1) Develop and demonstrate a novel nano-coating method for carbon fibers based on one-step exchange-cross-linking- precipitation to generate a highly conductive metal nano-layer (less than 50 nm) around carbon fibers; (2) Identify the underlying technical issues that govern the fabrication and performance of the coating system; and (3) Use this knowledge to design and manufacture such highly conductive metal nano-coatings around carbon fibers that exhibit the extinction coefficient required by Army. The anticipated technological impact of the proposed research program is the development and implementation of a low-cost nanoscale thin-film fabrication concept based on stabilized metal nanoparticles that provide the performance of metal-coated carbon fibers exceeding that with commercially available technology.

Title:Low-Cost Method for Metal Nano-Coating of Anisotropic Fibers
Abstract:Physical Sciences, Inc. (PSI) proposes to demonstrate the low cost fabrication of chopped carbon fibers with a 50 nm thick, continuous copper coating deposited by electroless methods. We will utilize electrospinning to fabricate uniform polyacrylonitrile fibers with a diameter that upon pyrolysis will yield carbon fibers with 2 micron diameter. The polymer fibers will be pyrolyzed under tension to yield straight carbon fibers. These continuous fibers will be chopped to provide lengths of from 3 to 6 mm, for the 2 micron fibers. Because the fibers are straight, they will be relatively easy to disperse. The copper coated anisotropic carbon fibers are expected to have an extinction coefficient exceeding 6 m^2/g at 35 GHz. During the Phase I Option, PSI will fabricate 1 micron diameter, copper coated fibers. The Phase II program will enable diameter, aspect ratio and electrical conductivity tuning and process scale-up to the kg level. Our expertise with electrospinning scale-up to produce 5 km long tows of 3 micron polymer fiber enables a solid baseline production to build upon in Phase II.

Title:Compact and Mobile Biofuels Production System for Forward Sites
Abstract:To support tactical fuel requirements at forward sites, biomass wastes from operations and those locally available need to be converted into viable military fuels. Conventional approaches cannot produce military type fuels using compact and mobile reactors. Through recent efforts, Altex and PSU have identified a novel approach that can achieve the conversion of mixed biomass wastes to a JP-8-type fuel in a compact and mobile platform. Preliminary tests have shown the potential of the concept and the needed components have been integrated on two mobile trailers to allow testing in the field. Under the proposed Phase I project, the concept will be adapted to the Army biomass waste to military fuel application of interest; and the performance and cost benefits of the concept will be determined versus alternative techniques. In support of this assessment effort, a subscale test article will be built and tested. These efforts will show the feasibility of the concept for Army biofuels applications of interest.

Title:Bimodal Standoff Biometric Collection System
Abstract:To address the Army need for standoff capture of multimodal biometrics, Physical Optics Corporation (POC) proposes to develop a new Bimodal Standoff Biometric Collection (BISBIC) system for multimodal high-resolution biometric capture, based on POC''s innovative nonoptical zoom with wide field-of-view (FOV) technology with a ultrasuperpixel array. It is based on POC’s innovative, ultrawide-FOV (90 deg. x 12 deg.) technology with no moving components, volume captures (no orientation requirements) and a superfocal-plane array. BISBIC performs instantaneous electronic zoom on biometrics (iris and face) without restricting the subject’s activities or orientation. BISBIC features wide capture volumes in all orientations with instant, telescopic, high resolution (0.1 mm) at 100 meters, which is unprecedented. The BISBIC package is 12 in. (dia) x 8 in. (long), and <10 lb. In Phase I POC will demonstrate the feasibility of BISBIC by building and testing functional BISBIC components in a laboratory testbed. In Phase II we plan to design, fabricate, and test a fully functional prototype in a realistic environment.

Title:Composit Tracking and Discrimination Module
Abstract:The project objective is to develop a set of mathematically rigorous Composite Tracking and Discrimination Modules (CTDMs) for accurately fusing both kinematic and non- kinematic sensor information to contribute to a consistent Single Integrated Air Picture (SIAP) containing both Tactical Ballistic Missiles (TBMs) and Air Breathing Targets (ABTs). A distributed data fusion architecture is assumed. Local (sensor level) tracks are formed based on measurement-to-track fusion. Multi-sensor system tracks are formed based on track-to-track fusion. The target state vector includes both kinematic and feature states (such as radar cross section and color temperature). Non-linear state estimation methods employed include extended Kalman filtering, a Gaussian sum representation for the target state distribution, and the modified Euler method for approximating the solution to the target state SDE. Data association is formulated as a classical assignment problem. Data association hypotheses are generated using the Munkres algorithm. A graph-theoretic algorithm is used to form cluster tracks partitioning the data association problem into independent subproblems. The bandwidth required to communicate tracking data across the distributed network is reduced by sending pseudo-measurements that capture the information from multiple physical measurements. A Bayesian inference engine performs the target discrimination and classification function. Multi-sensor registration is performed using non-Gaussian methods.

Title:Sensor Geodetic Registration for Tactical Ballistic Missile (TBM) Composite Tracking and Discrimination Capability for Army System of Systems (ASoS) I
Abstract:Critical to the success of distributed sensor fusion for IAMD is the ability of each network sensor to correctly associate sensor measurement and attribute data to tracked objects within the air/missile picture. To achieve this, multi-sensor fusion requires sensor registration techniques that ensure network sensor are sufficiently synchronized and spatially aligned. The goal of sensor registration is to reduce the range of uncertainty inherent in a given single radar by considering the "cross correlations" that exist between the data on common tracks observed by network sensors. Our approach to sensor registration is to provide geodetically aligned sensor data within a component based distributed architecture using methods that act on geodetic calibration tracks and other fiducial data points common to the distributed sensors to produce location and orientation bias estimates at each sensor. The distributed architecture allows each sensor to compute local biases and apply the computed “offsets” prior to distribution of track data to the tracking network. Sensor registration using simultaneous observation of selected common tracks and fiducial points among distributed sensors has the potential to compute a local sensor registration solution by averaging out the uncorrelated random bias errors that will be present within the ensemble of networked sensors.
