| Title: | Broad Spectral Range Detectors for Vis/SWIR Focal Plane Arrays |
| Abstract: | Aerius proposes to build detectors with low dark current and a cutoff wavelength of 3.0 um, using InP-based detectors. These detectors do not suffer from the same problems conventional "extended-wavelength" suffer, such as high dark current, low quantum efficiency, and limited spectral range. Aerius proposes to achieve, high quality, high uniformity extended short-wavelength infrared (SWIR) detectors that can also be sensitive to short wavelengths in the visible. Realizing this material would extend the capabilities of satellites and kill vehicles by detecting both reflected light and thermally generated wavelengths in one detector, reducing the cost and mass of detector deployment. |

| Title: | Nano-Enabled Broadband Infrared Anti-Reflection Coatings |
| Abstract: | In this program, Agiltron and the group of Professor D. W. Wang at Boston College propose a novel nano-porous coating for next generation MDA IR anti-reflection (AR) coatings for detectors and optics. The collaborative research leverages recent progress in nano-material development at Boston College, and Agiltron's recently developed nano-coating processes. The proposed IR AR coatings will possess engineerable nano-porosity and predefined index profile characteristics along with extremely precise thickness control. These coatings can be expected to yield graded index profiles as well as discrete multilayers leading to the first universal IR AR solution for critical surfaces. The coatings will also possess superior radiation hardness, broadband anti-reflection, good thermal-mechanical stability, and both high and low temperature stability critical for a space environment. Additionally, our nano-porous coatings are obtained by a low cost wet chemistry process compatible with state of the art detector fabrication. Nano-porous coatings can also be applied to other IR optical components such as IR lenses and windows. The feasibility of the proposed approach will be demonstrated in Phase I. In Phase II, we will test its applicability to practical sensor surfaces and show net improvements in detector performance. |

| Title: | Long-to-Very-Long-Wavelength Infrared Band-Pass Filters for Space Infrared Detectors |
| Abstract: | This Phase I SBIR proposal requests innovative sensor solutions to improve strategic space sensors. One route of improvement is selective band-pass filtering of radiation before it reaches the detector. Such filtering can improve detection by blocking out-of-band interferences and allowing transmission of the desired spectral components. Filtering can improve a cheaper detector with a broader detection profile into a high performance detector. Filtering can also improve signal-to-noise of a detector by eliminating out-of-band radiation from reaching the detector and causing spurious signal or A/D saturation. Comparable band-pass filters in the mid-infrared are typically thick multilayer dielectrics subject to poor adhesion between layers, thermal mismatch stress, or moisture sensitivity which can lead to destructive delamination. The innovative very-long-wavelength-region band-pass filter design proposed here has high transmission, can tolerate cryogenic temperatures, ionizing radiation and vibration making them launch-capable. The 2mm-thin proposed band-pass filter allows insertion into tight spaces. Lake Shore has demonstrated prototype band-pass filters with center bands from 14 - 25 microns in the infrared spectrum. By using innovative fabrication, it will be possible to extend this range down to the long-wavelength-infrared region. New IR detectors, developed in-tandem with Lake Shore band-pass filters can produce a high-performance solution for MDA applications. |

| Abstract: | Quallion currently manufactures hermitically sealed, prismatic 15Ah and 72Ah lithium-ion cells for the aerospace community. The cells are undergoing real-time life testing at various government agencies, in which the 15Ah cell has demonstrated over 12,000 LEO cycles at a 60% depth of discharge (DOD). Under these conditions, Quallion expects the cell to perform over 50,000 cycles. In this effort, Quallion will modify its existing long-life high energy density chemisty to meet high rate capabilities. Once modified, Quallion will incorporate this chemistry into the same form-fit factor of our current satellite cells. |

| Title: | High-Efficiency, Radiation-Hardened, Power Converter System for Distributed Space Applications |
| Abstract: | VPT Inc. proposes to develop an innovative radiation-hardened, high-efficiency, thick-film hybrid DC-DC power converter that addresses demanding MDA space application needs. The targeted technology will provide efficiencies of greater than 90% for multiple low output voltages. The proposed system includes a single output isolated DC-DC converter with synchronous rectification to convert a standard MDA 28V bus directly down to 5.0V as well as multiple non-isolated point of load converters to obtain output voltages from 3.3V to as low as 0.8V. This system will be based on VPT standard product, Mil-PRF-38534 Class K hybrid DC-DC converters and recent VPT radiation analysis and testing including Total Ionizing Dose (TID), Enhanced Low Dose Rate Sensitivity (ELDRS), Radiation Lot Acceptance Testing (RLAT), Flash Xray (FXR), Single Event Upset (SEU). In the SBIR Phase I VPT will perform the following: (a) develop a multiple output converter breadboard using the new VPT hybrid converters and demonstrate electrical performance including high efficiency, (b) select and characterize new radiation-hardened components (c) perform circuit design changes and analysis to achieve 500kRads of total dose radiation performance and 60MeV of single event upset capability, (d) evaluate planar winding magnetics for high efficiency and wide temperature range of operation. |

| Title: | High Performance Rad Hard Analog to Digital Converter Architectures |
| Abstract: | Electronic components for future space based radar systems on chip (SOC) must function correctly in natural and radiation filled environments while providing state-of-the-art performance. The corresponding SOC must employ advanced, extra low-power, radiation-hardened (RH), analog-to-digital converters (ADCs) capable of operating at multi-giga sampling speeds. To satisfy the described needs, we propose to develop an ADC block with 9 bits of resolution and up to 10Gs/s of sampling speed. The 9 bit wide data will be demultiplexed by a factor of eight to a rate of 1.25Gb/s for direct loading into a following FPGA where signal processing will be performed. Our patent-pending radiation-hardening techniques incorporate a methodology based on protection and redundancy, which provides both total ionization dose (TID) and single-event upset (SEU) tolerance within the IC. The proposed high performance characteristics of the ADC will be achieved by utilizing an advanced SiGe IC fabrication technology. |

| Title: | High Sample-Rate Ultra-Wideband Track-and-Hold Demultiplexer (2007047) |
| Abstract: | Hittite proposes to develop a Radiation-Tolerant Ultra-Wideband Track-and-Hold (T/H) Demultiplexer to address MDA's future needs for microwave signal sampling/data conversion. This development is motivated by the difficulties in achieving high-speed interleaved analog-to-digital converter (ADC) assemblies with good accuracy. A switched-emitter-follower T/H amplifier in the SiGe BiCMOS process with the capability for 15 GHz sampling bandwidth, 6 - 8 Gs/s sample rate, and 8 - 9 bit accuracy will be studied. This high-speed T/H will be used as the front end of a two-rank T/H sampler/demultiplexer that provides a 2:1 output sample rate reduction, enabling the use of lower rate ADCs in an interleaved assembly without the usual sample timing mismatches that degrade performance. The T/H demultiplexer can also operate as a subsampler to down convert any Nyquist bands within the 15 GHz bandwidth. This T/H circuit is expected to offer unprecedented bandwidth and operating speed while maintaining accuracy suitable for meeting the X-band and microwave data conversion goals of many military systems. Under Phase I, Hittite will perform a design study with circuit simulations to determine the feasibility and performance of the basic T/H amplifier and the two-rank demultiplexer. Prototype circuits will be built and tested in Phase II. |

| Title: | Multiplexed, Rad Hard ADC |
| Abstract: | The proposed part is a rad-hard, 16-input, 14-bit ADC, with aggregate speed of 200 MSPS. The 16 inputs are sampled individually and can be configured as 16 single-ended inputs or 8 differential inputs. The ADC provides 14 data outputs, a data-ready signal, and an over-range indicator. The digital outputs of the ADC are CMOS low-voltage differential signal (LVDS) outputs. The part will be fabricated using Texas Instruments' BiCom3X, a SOI process with CMOS and complementary SiGe bipolar transistors. SiGe bipolar transistors typically have very high total dose hardness, and we are not aware of an ELDRS problem. The SOI wells prevent latch-up and restrict the silicon volume that can produce photocurrents from either ionizing dose rates or single event strikes. Our designers, Bill Poland, Jim Swonger, Wayne Dietrich and John Branning, have designed over 140 ASICs, many of them rad-hard. They worked together on a 14-bit rad-hard ADC, on which the proposed part is based. Nu-Trek is an emerging suppler of rad-hard parts, with four parts coming on sale in 2008. The Nu-Det has already been inserted into the MKV and NGIMU. The Clam/NED is slated for insertion in the Army's FCS. |

| Title: | High Performance Rad Hard Analog to Digital Converter Architectures |
| Abstract: | Orora Design Technologies proposes to develop and demonstrate the feasibility of a template-based solution to the design of high-performance radiation-hardened analog-to-digital converters (ADCs). Research will be focused on innovatice architectures for a Delta-Sigma ADC of 2.5 MSPS data rate at 16-bit or greater resolution with 250mW or less power consumption, and a pipelined ADC of 180MSPS data rate at 14-bit or greater resolution with 540mW or less power consumption. Baseline radiation goals are 300Krad total dose, and single-event latchup immune and single-event upsets with LET greater than 15, and bit error rates less than 1E-10 errors/bit-day. The output of this research is template-based architectures and a behavioral model library that captures expert radiation-hardening design techniques and can be adapted to different design performance requirements and fabrication processes. In addition, a set of enabling computer-aided design tools will be developed in a mainstream EDA design environment and can be used by avionic electronics designers. The technical novelty of this research consists of (a) joint optimization of architectures, processes, and circuits for varying applications and radiation hardness, (b) hierarchical radiation-aware parametric behavioral modeling, and (c) adaptive design templates. |

| Title: | An Advanced Thermal Management System for Gimbal-Mounted Sensors |
| Abstract: | Future missile detection systems will require improved thermal management for cooling gimbal-mounted sensors and optics. Current systems utilize cryocoolers placed on the gimbal, which necessitates the cryocooler heat to be rejected directly from the gimbal. A far superior approach in terms of payload mass would locate the warm elements of the cryocooler on the stationary platform near the spacecraft heat rejection system, and place only the cold elements required to cool the optics and sensors on the gimbal. On the proposed program, we plan to develop an innovative cryocooler for cooling gimbal-mounted sensors and optics. The cryocooler is based on space-proven turbo-Brayton technologies which will be adapted to the unique requirements of this application. The inherent attributes of the turbo-Brayton cycle permit the warm components of the cryocooler to be mounted off gimbal, which will drastically improve thermal management and reduce payload mass. The warm and cold components of the cryocooler will be connected using custom flexible tubing, which has been demonstrated to provide the flexibility and life required for gimbaled systems. In Phase I we will develop a preliminary design of the cryocooler and its components, develop performance curves, and perform trades to establish a packaging and integration concept. |

| Title: | Experimental Demonstration of an Improved Cryocooler Configuration to Lower the Gimbaled Mass and Volume for Infrared Sensors |
| Abstract: | The objective of this effort is to reduce the weight of the cryocooler system, improve the efficiency of the cryocooler system, provide multiple cryocooler temperatures, and improve the configuration of the gimbaled flexible joint. At first glance, this set of claims seems incredibly ambitious; however, as disclosed in this proposal, these achievements can be obtained by implementing an improved cryogenic cooler. The proposed configuration can also provide multiple cooling temperatures, allowing both the cryogenic cooling and the electronics thermal control from a single cooler. This Phase I effort includes the experimental demonstration of this cryocooler (in a bench-top configuration), as well as a demonstration of an improved gimbaled flexible joint. Phase I also includes a comparison with current state-of-the-art technology to verify mass, reliability, and energy benefits. Clearly, Mainstream has the prior experience in this area, and the effort proposed in Phase I, which includes a preliminary design and bench-top demonstration experiments, exceeds the scope of effort proposed in the Phase I solicitation; however, Mainstream is well into this research and excited about the commercial potential for this technology. Phase II will address the fabrication and demonstration of a complete system. |

| Title: | Advanced Heat Rejection Methods for Space Cryocoolers |
| Abstract: | Future space EO systems will require cryogenic subsystems that are substantially more powerful than those presently in use. Input power levels are expected to increase by a factor of 2X to 4X, necessitating changes from the payload level down to the cryocooler subsystem level. Payload-level changes involve the inclusion of more robust power busses and heat rejection systems, while changes to the cryocooler subsystem will focus on optimization of the internal heat rejection schemes to allow the thermo-mechanical units to run at relatively cool internal operating temperatures despite the increased power load. The South Bay Science and Technology Corporation (SBSTC), as the prime contractor, and Raytheon, as subcontractor, propose to develop high efficiency Closed-Cycle Cryocooler waste heat rejection designs as part of a system solution for electro-optical (EO) space payload power and mass reduction. |

| Title: | Relational Pattern Analysis Tool for Legacy Conversion |
| Abstract: | This project develops a technology to automate the interpretation and understanding of complex trees of source code and related artifacts for conversion to run on newer hardware, operating systems and languages. The center of our proposed innovative approach is to map and parse a complex source code tree (plus related artifacts such as `makefiles') into an appropriate process and object oriented schema tree. From this representation we propose to generate relational database queries, stored procedures and advanced algorithms that extract dependencies and partitioning with respect to hardware, operating system, distributed processing, application programming interfaces [APIs], etc. The proposed tools will help analysts visualize, analyze and gain a deep, multi-level understanding of legacy code. This approach supports automation of legacy code functional inventory, language translation and re-partitioning. The solution is extremely flexible and applies to multiple versions of Ada (ANSI/MIL-STD 1815A, ISO-8652:1987, ISO/IEC 8652:1995/Amd 1:2007). We also propose to develop a plug-in for a popular software tool such as Eclipse. This approach has potential to yield order of magnitude reductions in the man-hours/cost required to modernize Ada applications. |

| Title: | LANguage Conversion Engine (LANCE) |
| Abstract: | From 1987-1997, DoD required Ada for every software project where new code generation was more than 30% of the effort. With the decline in Ada's popularity, it has become increasingly difficult to find skilled Ada developers to maintain this legacy code. Code maintainers that don't know Ada typically convert the code to a language they understand and this is a tedious error-prone process. What is needed is a toolkit that converts Ada into more widely supported languages, provides guidance on translation, and plugs in to the maintainer's IDE. Such a toolkit must provide a view of each module within the context of the legacy application and weigh the relative merits of various conversion options. The converted code must also be validated against the legacy code to ensure accurate and effective conversion. Our proposed LANguage Conversion Engine (LANCE) will not only accurately translate and validate Ada code but also provide the necessary guidance to wrap or rewrite code that can not or should not be translated. This guidance will include the necessary metadata to integrate the various code modules that have been translated, wrapped, and rewritten. Finally, the system's software repository will store translated code modules for cataloging and reuse. |

We develop an innovative new toolset that guides the engineer through a comprehensive methodology to inventory and understand the legacy system to be modernized, estimate the cost benefit of reusing versus rewriting the legacy code, extract and translate reusable components from the legacy system for use in new architectures, and verify the correctness of the translated code. Our toolset improves upon the state of the art in several ways: breaks the "black box" of most conversion methods to facilitate a human-involved process of discovery; reduces cost by automating tedious migration tasks; fosters and encourages "educated conversion," allowing the engineer to understand the code as it is converted; preserves understanding for future engineers through a repository of reusable components, documentation, and annotations; and utilizes flexible methodology and Open Source technology including Eclipse to provide a robust platform for migrating legacy code to C++ that is extensible to C++ .NET, Java, and other languages within STSS and beyond. |

The methodology proposed build models of the application and then analyzes them using to ensure that they properly represent the software as it actually runs on the platform and in the environment to which it is targeted. The methodology relies on aspects to capture processor/platform dependencies and domain models for a determination of which functions it makes sense to carryover for redesign. The utility and effectiveness of the methodology will be verified during Phase I through the use of a pilot project.

| Title: | Low Cost Calibration Test Objects for MDA Systems |
| Abstract: | Development of the electro-optical sensors for use by the MDA requires flight testing against calibration targets that have well characterized radio frequency, optical and infrared cross sections. These tests are very expensive therefore there is a compelling need for low cost calibration targets. Providing well characterized visible and radar targets is reasonably straight forward, however IR is not. To solve this problem we are proposing to develop black balloons that are inflated with a liquid inflatant that has a surface tension below the critical value that allows complete wetting of the inside surface of the balloon. This will provide an isothermal target to within a fraction of a degree. If the balloon is made of a material like black Kapton then the reflected radiation will be specular, so both the IR and the visible spectrums will be independent of the viewing angle or solar angle. Also since the Kapton is carbon filled its radar signature will also be well characterized. This very simple target balloon design when married with existing L'Garde flight proven designs for the balloon canisters and ejectors will meet the MDA price goal of less the $250,000. |

| Abstract: | Systems & Processes Engineering Corporation (SPEC) proposes the low-risk adaptation of existing flight-proven MDA Targets & Countermeasures (TC) subsystems to meet the requirements of this topic. In an increasingly tight budgetary environment, the frequent calibration testing needed by new, modified and operational sensors must be accomplished in a much more cost and schedule efficient manner. SPEC's Modular Adaptive Low-cost Test System (MALTS) concept is a much simplified lower-cost derivative of an equivalent system developed and flown under the MDA/LMCO BMDS Targets & Countermeasures Prime Contract (TCPC). SPEC and teammate ITT Industries are very familiar with the requirements for well characterized test objects, as a result of being a current provider of MDA target systems and with personnel long involved in ballistic missile penaids and SDIO targets, going back to the mid-1960's on the Minuteman-II Penaids Program(s) and continuing on every US ICBM reentry system since then. The baseline MALTS concept, fully compliant with topic requirements, consists of a programmable pneumatic ejector and a spherical inflatable test object. Both have been flown successfully and are suitable for launch on sounding rockets, ICBMs, space launch vehicles or from satellites. Recurring unit flight test cost will be well under the $250K goal. |

| Abstract: | Proposed Missile Defense Agency (MDA) systems, such as the Space Tracking and Surveillance System (STSS), require high precision gyroscopes for high-resolution Line of Sight (LOS) stabilization and pointing control for the acquisition, pointing and tracking (APT) systems. To achieve these mission objectives, MDA is very interested in the development of compact, high performance, space qualified micro-electro-mechanical systems (MEMS) gyros. The recently developed MEMS Disc Resonator Gyro (DRG) has the potential of fulfilling the MDA MEMS gyro requirement. Research associated with the volume manufacturing for the DRG is currently underway by Sensors in Motion (SIM). However, miniaturized, low power, and radiation hardened electronics have not yet been developed for the DRG and ultimately required for satellite applications. ATA proposes to develop miniaturized, radiation hardened electronics for the DRG for realization of MDA's MEMS gyro needs. High performance DRGs incorporating compact optimized electronics would be used extensively in precision inertial reference units (IRUs) and inertial measurement units (IMUs) with the advantage of much smaller size and weight, less power, and also less cost due to the mass production implications of MEMS devices in general. High performance MEMS DRGs would facilitate MDA's space-borne applications that cannot be fulfilled with current gyro technology, i.e. HRGs, RLGs, FOGs, and DTGs, because of size, weight, power, and cost limitations. |

| Title: | Flight-Weight Ceramic Composite Monopropellant Rocket Thruster Assembly |
| Abstract: | Rocket thrusters based on hydroxyl-ammonium nitrate (HAN) monopropellants are of interest for Network Centric Airborne Defense Element (NCADE) missile axial and divert propulsion applications because of their inherent system simplicity, low toxicity, high specific impulse (~275s), and 50% greater density-specific impulse over hydrazine (Isp¯220s). Their high combustion temperatures (33300øF), however, pose significant challenges on chamber and bedplate materials. In order to exploit the performance benefits of HAN, advanced materials, such as SiC composites, reticulated SiC foams and lightweight end-closure joining methods are needed. SiC composite and SiC foam catalyst bedplates have demonstrated superior performance qualities in recent hot-fire testing at AEROJET, while significantly decreasing weight and manufacturing cost over alternative designs and materials. Hyper-Therm HTC's SiC composite thrust chambers and SiC foam bedplates have been selected by AEROJET for several MDA missile applications, however composite chambers have not yet been demonstrated using HAN. Moreover, a method for efficiently joining the composite chamber to the metallic forward end-closure is essential to the success of affordable flight-weight composite propulsion devices. The objective of this program is to develop a flight-weight composite monopropellant rocket thruster consistent with the requirements of NCADE for hot-fire evaluation. High-performance SiC composite thrust chambers incorporating ultra-lightweight SiC foam catalyst bedplates and utilizing a weight-efficient end-closure joining method will be developed in Phase I and prepared for hot-fire testing by AEROJET using HAN early in a Phase II program. |

| Title: | Light Weight Thrust Chambers for Advanced Interceptor Axial Propulsion |
| Abstract: | The Network Centric Airborne Defense Element (NCADE) is an affordable boost- and ascent- phase ballistic missile interceptor system. NCADE has the same form, fit and interface as the Advanced Medium Range Air-to-Air Missile (AMRAAMT). The boost- and ascent-phase capability of NCADE is enabled by high-altitude launch and a high performance two-stage propulsion system. The second stage uses a hydroxylammonium nitrate (HAN) based monopropellant for all upper stage propulsion, including axial, divert and attitude control system, to provide endo- and exoatmospheric flight. The combustion environment of high-performance HAN formulations is both high temperature (>1700øC) and corrosive (nitric acid, steam, carbon dioxide). The biggest technical challenge for HAN based propulsion systems is developing low-cost, lightweight thrusters and hot gas valves to withstand the extreme temperature environment of combustion products. Lining carbon-carbon chambers with a thin layer of rhenium or iridium is an innovative way to both economically use refractory metals and improve the performance of high temperature composite chambers. This proposal will evaluate using iridium-lined carbon-carbon to form a composite structure for HAN axial thrusters and DACS gas generator components. |

| Title: | Chemical Vapor Composite (CVCT) SiC for HAN Propulsion Systems |
| Abstract: | Trex will develop rocket motor components suitable for liquid HAN monopropellant propulsion systems utilizing its patented CVC SiCT process. CVC SiC enables production of high quality SiC capable of handling extreme temperatures up to 3700oF, well within the requirement for the HAN propellant. Furthermore, near net shape fabrication of rocket motor components, such as nozzles, flame liners and pintles is possible via CVCT. Finally, addition of solid particles and chopped fibers has been demonstrated, which yield stress-free, robust composite SiC materials required for the extreme pressure and thermal loads in the intended application. The proposed Phase 1 will produce prototype, near net shape CVC SiCT fiber-reinforced composites, thereby demonstrating a cost-effective manufacturing process for these high temperature components. |

| Title: | Multi Nozzle Grid Technology Application to MDA Missile Systems |
| Abstract: | As the US missile defense capability matures there is a growing need for new technologies that enable smaller packaging envelopes and higher mass fractions with improved performance. One such promising technology is the use of Multi Nozzle Grids (MGN) in place of conventional rocket nozzles. The MGN technology packages an array of small "nozzlettes" that individually exhibit high performance expansion ratios and collectively provide large delivered thrust. An MGN nozzle provides the benefit of reducing conventional nozzle lengths (up to 10:1), reducing system weight while potentially improving overall delivered performance. To demonstrate the benefits of the MNG technology to an MDA missile system Valley Tech Systems (VTS) is proposing a Phase I SBIR program for the conceptual design modeling and establishment of processing methods for an MNG nozzle. This Phase I program will provide the design and analyses foundation to proceed into a Phase II demonstration that substantiate the MGN technology benefits to the MDA missile system. |

| Title: | Actively Stabilized MEMS IMU for Autonomous Guidance and Navigation |
| Abstract: | Without the means for stabilizing the scale factor and bias of MEMS gyroscopes and accelerometers, they cannot become precise and accurate instruments. With stabilization, however, autonomous navigation is possible and GPS reliability can be improved. We propose to introduce active stabilization methods and test devices and carry out the proof-of-concept tests during Phase I. We will make use of existing hardware from related programs. The significance of the bias stabilization method to performance is that the formerly limiting 1/f - derived bias instability can be greatly reduced, with the potential of obtaining less than 1 deg/hr. An added importance of the scale factor and bias stabilization methods is the reduction in testing required and the corresponding drop in cost. |

| Abstract: | SA Photonics is pleased to propose a program to develop a low cost navigation grade Fiber Optic Gyro development program. There has long been a desire to build a low cost fiber optic gyro using single mode fiber, but various noise sources have precluded this dream from being realized. The scientists at SA Photonics, utilizing their more than 30 combined years of navigation grade Fiber Optic Gyro development experience, have created simple innovative solutions for these noise terms that will finally achieve the long anticipated goal of a low cost navigation grade single mode fiber optic gyro.

| Abstract: | This proposal addresses the need for a low-powered, low-noise, high-sensitivity, jam-resistant P/M code capable GPS receiver which can continuously track a GPS signal under high-g environments. The system incorporates several innovative technologies. First, the system is designed to keep the intrinsic system noise to a minimum. Second, a sensor suite incorporating an inertial measurement unit (IMU) is interfaced to the system and an ultra-tightly coupled algorithm incorporating a nonlinear filter to integrate the equations of motion increases the system sensitivity, allowing it to operate in environments where signal strength is severely. Third, the system is designed to be jam-resistant. In addition, the system has been designed for low power consumption and portable dimensions using commercially available off-the-shelf components. Using such components also helps keep system cost to a minimum while providing the required system performance. |

| Title: | High Performance Structures with Synergistic Composite Conductors |
| Abstract: | IST is proposing to integrate electrical conductors and antennas directly into composite structures using a new Synergistic Composite Conductor (SCC). IST's novel SCC technology enables small cross section electrical conductors that can be printed on or embedded into composites without degrading their structural performance. The benefits of this approach include better resistance to vibration and shock related wear, and inherent EMI shielding. There are also secondary weight advantages due to the elimination of electrical wiring clamps and the associated fastener holes which in turn allows for thinner composite cross sections. Printing or embedding the "wires" in the composite also provides support along their entire length which enables wires to be sized solely by current requirements and not g-loading. This will lead to thinner gauge wires and further synergistic weight savings. The Phase I program will demonstrate the feasibility of these new synergistic composite conductors and set the stage for electrical systems to be integrated into a larger demonstration article in the Phase II program. The Phase II will culminate in the fabrication of an electrical circuit or communications antenna embedded in a structural composite. |

| Title: | Multifunctional Metal RubberT Composite Structural Materials |
| Abstract: | This SBIR program would develop multifunctional structural composite materials based on NanoSonic's Metal RubberT. The Metal RubberT composites would offer mechanical stiffness-to-weight comparable with conventional cross-ply laminate face sheet and structural composite materials, but also incorporate high electrical conductivity, broadband RF/EMI shielding, and uniform thermal conductivity typically not available in polymer matrix composite systems. Metal RubberT is a self-assembled nanocomposite material that combines conducting nanoclusters and advanced polymers into free-standing sheets. These materials would be combined as plies with high performance reinforcement fibers to create cross-ply laminate composites during Phase I. Prior work has demonstrated low mass density (<1g/cc), highly electrically conductive (10-6 ohm∙cm), and useful RF and microwave shielding properties for NanoSonic's Metal RubberT ply materials. During Phase I, NanoSonic would modify the chemistry of its current Metal RubberT materials to allow their consolidation into composite structural materials using normal processing routes. Multiple Metal RubberT composite structural test articles would be delivered and evaluated to determine RF/EMI, electrical conductivity, thermal uniformity, useable temperature range, UV degradation and outgassing properties. NanoSonic would work with a large aerospace prime contractor involved in multiple MDA platforms and systems to design multifunctional requirements into Metal RubberT composite performance, and evaluate properties of test articles. |

| Title: | Advanced Synergistic Structures for Interceptor Kill Vehicles |
| Abstract: | The MDA has been investing in advanced structures and components technology development and demonstration programs for exoatmospheric interceptors for the ERIS, BP, SBI, EKV and GBI, and the MKV weapon systems. Significant advances have been achieved in mass and volume reduction for these interceptor kill vehicles; however, to achieve the mass reductions required for the next generation KV's, whether in space or on the ground, it will require the elimination of mass associated with enclosures for electronics. SDC proposes to leverage its 25 years of experience with kill vehicle requirements, technology, as well as SDC's strong relationship with KV system contractors to develop designs that fully integrate electronics subsystems into the primary structure. The feasibility of embedding three distinct types of electrical components into the composite interceptor structure will be explored: power and ground, data communication busses and antennas and processing components. This study will explore the benefits of embedding the components into the structure, determine which components would provide the best weight advantage, and conclude with the design and fabrication of a composite interceptor subcomponent. An element of the study will be the use of modular construction to change high value components in space via man or robotics. |

| Title: | Interceptor Algorithms |
| Abstract: | The evolution of advanced missile threats calls for interceptors with increased maneuver agility operating seamlessly in and between the boundaries of low endo-, high endo- and exo-atmospheric regimes and blurs the separation of interceptor fly-out and autonomous kill-vehicle end-game. In order to meet with increased target maneuver capabilities, the kill vehicle must supplement when possible its thruster based divert capability with aerodynamic lift which is the source of considerable model uncertainties. This poses major control architectural challenges and raises serious robustness issue difficult to meet using traditional control techniques. This proposal is about the use of novel Higher Order Sliding Mode HOSM control techniques in the design of seeker tracker and observers, guidance and automatic pilot. HOSM control is output based and not plant model oriented. It requires very limited knowledge of the plant and is perfectly robust to model uncertainty. Using the fly out characteristics and endgame guidance requirement of several known interceptors such as the ground based Theater High Altitude Area Defense (THAAD), sea based Standard Missile (SM3), and ground based midcourse Multiple Kill Vehicle (MKV) and given an assumed advanced maneuvering threat this effort will explore the potential of developing a new agile kill vehicle GN&C that can operate in all phases of flight: boost, midcourse, and terminal and its associated guidance, navigation and control laws for the most advanced threats without being constrained by the current approaches. |

| Title: | Adaptive Methods for Target Tracking, and Guidance and Control for the U.S. Ballistic Missile Defense System |
| Abstract: | Ballistic missiles pose formidable challenges for target tracking and intercept because of their spiraling dynamics and significant maneuverability potential as they re-enter the atmosphere at high speeds. Recent studies have shown that conventional methods to estimation, guidance and control design are unable to guarantee sufficient accuracy against such highly maneuvering targets. This is not unexpected since the coupling between the individual elements is not accounted for completely using the conventional design paradigm, and the separation principle which is implicit in such designs can break down in engagements that require high maneuverability. To meet these challenges we propose developing i) adaptive integrated guidance and control (G&C) designs for increased performance and robustness to uncertain interceptor dynamics, ii) adaptive target-state estimation designs for increased performance and robustness against maneuvering targets, iii) an integrated design method for combining adaptive target-state estimation and adaptive G&C designs for improving overall system performance, and iv) collision avoidance methods to avoid mutual kill-vehicle collisions. The adaptive methods are based on flight proven Neural-Network based adaptive control algorithms. We expect that our strategy for integrated adaptive designs can produce never before achieved levels of lethality for the intercept of future maneuvering targets. |

| Title: | Seamlessly Integrated GNC Algorithms for Multi-Missile Interception |
| Abstract: | We propose an integrated missile interception approach that ensures seamless transition between fly out guidance phase and end game guidance phase under environments with complex noises and multiple weapon/sensor resources. Several distinctive key features are as follows: 1) Rather than attempting achieving fly-out guidance laws that will invariably require information on time-to-go, continuous feed on target motion, linearization or other unrealistic assumptions, our fly-out guidance approach is based on fast on-line solution to a 3-D optimal control problem. The guidance allows optimally determined two-pulse fly-out strategy, easily incorporates any updated target motion data, and affords seamless transition to end-game guidance; 2) A new end game guidance law which considers time-varying parameters, nose-tail bicontrol, estimation delay, and intentional/chaotic spiraling will be developed; 3) Variable Structure Interacting Multiple Model (VSIMM) estimation theory is applied to support our guidance and control algorithm. Such estimation approach is efficient for tracking different "class" target and/or in "dense" environment, i.e. in presence of a number of different threats corrupted by non-Gaussian clutters. The special structure of our VSIMM will greatly reduce computational complexity; 4) We will also refine game theoretic resource management algorithm and other supporting modules which will optimally utilize available weapons and sensor resources. |

| Title: | Hardware Accelerated Super Resolution for MDA Interceptors |
| Abstract: | MDA is currently developing advanced interceptors for its BMDS. Imaging technology is crucial to this effort for several purposes, including navigation, false-alarm/decoy identification, and estimation of position and speed of potential targets. Although high-resolution imaging systems are readily available, these require (1) power-hungry CMOS arrays (or FPAs) and (2) large-aperture optics, which are heavy, expensive and may not be compatible with the aerodynamic profile of high-speed interceptors. Fortunately, signal processing methods have been developed that enable high-resolution image-capture using low-resolution equipment exclusively, a family of algorithms know as super-resolution. Although super-resolution algorithms have been studied extensively by the research community, their implementation and deployment have been limited due to high computational cost and the inability to work in real-time in realistic applications. We propose the acceleration of super resolution routines using readily available hardware; in particular, an FPGA platform will be utilized given its compatibility with the power/size/cost requirements of missile interceptors. |

| Abstract: | MDA is in need of complete sensor test capability that enables test planning, test execution and test data analysis. Much of the test expertise and equipment capable of supporting these activities was dispersed following the termination of the various DTRA programs supporting them and limited emphasis on radiation effects in all MDA activities. We propose to establish an initial LWIR sensor test capability at RAD Longmire Laboratory using the government-owned NICS chamber, incorporating the NODDS scene generation capability and the methodology and hardware developed at Longmire Laboratory for sensor testing. Phase I of the proposed program will consist of an assessment of the NICS hardware, specifically the scene generation subsystems, and the feasibility of this incorporation. This reconstitution will allow rapid restart of sensor test activities at MDA and development of new test paradigms for space and MDA sensors as new technologies become available while retaining the services of all the critical experts in the area. Following this initial phase, the program will establish a process for bringing new capabilities on line, develop new test paradigms and transition these to the community. |

| Title: | HgCdTe Detectors Under Non-Equilibrium Conditions for High Operating Temperatures |
| Abstract: | High sensitivity HgCdTe infrared detector arrays operating at 77K can be tailored for response across the infrared spectrum and are commonly utilized for infrared focal plane arrays (FPAs). However, the cooling systems required to achieve the desired sensitivity makes them heavy and therefore unsuitable for many applications. Infrared arrays operating above ~200K could be thermoelectrically-cooled and integrated in lighter and more compact interceptor systems. This superior operating temperature could be provided by a system based on HgCdTe infrared detectors operating under non-equilibrium conditions. The concept is to suppress Auger recombination and the corresponding dark current, leading to dramatic increase in detector dynamic impedances and detectivities. This technology provides sensitive infrared FPA operation with response across the infrared spectrum at high temperatures, is compatible with multi-band response and large format technology, and therefore meets all major MDA sensor requirements. In Phase I, we will demonstrate high performance single detectors with response in the MWIR and LWIR bands and high operating temperature. Our goal is to achieve detectivities >10^9 cm.Hz0.5/W at operating temperature >200K. The efforts in Phase I may be extended to two-color detection, large-format full focal plane arrays and longer wavelength operation (VLWIR out to 14 um) in later phases. |

| Abstract: | Analytical Services, Incorporated, teamed with Davidson Technologies, proposes a new approach to the characterization of drag and lift coefficient distributions for debris resulting from missile intercepts. The proposed approach utilizes both theoretical considerations and available measured data obtained from flight tests or other sources. This approach uses the measured data to obtain best estimates of a "true distribution" derived from actual debris/fragment physical attributes. The ASI team proposes to use government furnished data from flight tests or other sources, along with transport and dispersion model propagators, to estimate a consistent set of drag and lift coefficient distributions with error estimates. This work is important because of the widespread use of transport and dispersion models along with debris distribution models, i.e., KIDD, and the use of software derivative products, such as Range Safety software, in the prediction of debris footprints. |

| Title: | Aerodynamic Characterization of Debris Fragments |
| Abstract: | The problem of debris propagation and impact location has been studied since the formation of the Missile Defense Agency because accurate prediction of where and with what probability the fragments created during an intercept will impact the ground is crucial to the determination of possible collateral damage. The Kinetic Impact Debris Distribution (KIDD) fragmentation model provides a tool for predicting the post-intercept behavior these fragments. However, the KIDD model is limited by the extent to which the aerodynamic characteristics of the debris are quantified. Andrews Space proposes the development of a surrogate-based debris aerodynamics model, drawing on empirical data, computational fluid dynamics (CFD), and statistical principles to quantify the lift and drag characteristics of irregularly shaped fragments during both the subsonic and important high-Q phases of flight. This model will be based on 1) a careful statistical classification of actual debris based on physical characteristics, 2) the development of a family of debris surrogates from this classification, 3) the analytical (CFD) modeling of these surrogates to validate their applicability and behavior in different flight regimes, and 4) the collection of wind tunnel data (during a Phase-II follow-on) to benchmark the aerodynamic characteristics of the surrogates. |

| Abstract: | The focus of this proposal is the aftermath of a successful missile intercept, where the resulting fragments fall toward land or sea. This study will develop an approach to quantify shape parameters in a useful way to feed to a designed algorithm set governing lift and drag. The goal will be to enable trajectory analysis based upon lift and drag characteristics. Driving parameters such as the size, mass, velocity, and the material structure will be defined and evaluated as they correlate to a fragment's lift and drag.Existing approaches have focused on the shape evaluation, formulating a plan to standardize shape parameters to enable a generic set of algorithms. Complex non-linear departure modes, such as tumbling, are difficult to replicate in a wind tunnel environment. For Phase I, computational methods, simulating the aerodynamics, are the most cost effective way of predicting non-linear departures for lift and drag. AVID intends to address this problem in three parts, geometry definition, aerodynamic analysis, and predictive techniques to correlate data. During Phase I, research into each set of prediction methodologies will be conducted with a method selected for further development during Phase II. In preparation for Phase II, AVID will develop a measurement approach for experimentally validating the aerodynamic characteristics of the fragments derived in Phase I. Novel wind tunnel testing techniques and deviations from more standard testing methods will be explored for the best possible test matrix to replicate fragment rotational free fall after impact. |

| Title: | Aerodynamic Lift and Drag Characteristics of Irregularly Shaped Fragments |
| Abstract: | An innovative aerodynamic database generation methodology is proposed for arbitrary fragment shapes. This will be achieved with automated CFD methods, using the framework of the Unified Flow Solver (UFS). The UFS features an Adaptive Mesh and Algorithm Refinement (AMAR) procedure for seemlessly coupling rarefied and continuum algorithms inside a simulation. The AMAR automatically creates Cartesian computational grids for arbitrary shapes and executes the analysis in an automated process. This simulation system will provide the analyst with a push-button computational tool for generating a deterministic ensemble of steady-state and tumbling body aerodynamic datasets. The deterministic collection of simulation results from this process will be utilized to formulate probabilistic fragment drag and lift cross range models that can be applied in existing debris tracking modules. This method will capture the complex variability of the lift magnitude and direction with sensitivities to shape, inertial and flow irregularities. In Phase I, A moving body capability will be added to UFS for simulating moving fragment flowfields, and the code will be validated and demonstrated for subsonic to hypersonic and continuum to rarefied aerodynamics predictions. In Phase II, the developed tools will be applied for generating datasets for fragment shapes at a range of combinations of Mach, Reynolds, and Knudsen numbers over the entire potential fragment trajectory space suitable for application in MDA debris tracking tools. |
