Title:Sensor Data Fusion
Abstract:Technology Service Corporation (TSC) proposes to apply the Dynamic Logic (DL) algorithm to perform target detection and tracking using data from multiple radar and IR sensor assets in the ballistic missile defense system (BMDS). This iterative algorithm performs these two tasks simultaneously, and can reduce the number of computations required. This can allow the BMDS to allocate additional resources to other critical tasks such as discrimination. TSC has demonstrated that the DL algorithm can detect and track dismounts using measured radar data. Under this Phase I effort, TSC will extend DL processing to perform detection and tracking of ballistic missiles using BMD radars and IR sensors. TSC will also develop a method of fusing raw radar and IR sensor measurements into a common reference frame and develop 3-D track estimates. The enhanced tracking capability and simultaneous target detection can support early engagement strategies such as launch-on-remote and engage-on-remote. In the Phase I Option, TSC will extend the fused DL algorithm to estimate sensor biases. In Phase II, TSC will mature the algorithm and test it on measured radar and IR data, as available, and address more challenging raid scenarios.

Title:Feature-aided Globally Optimized Sensor Fusion for BMD
Abstract:Physical Sciences Inc. (PSI) proposes to develop, evaluate, and test new elements of a sensor fusion architecture for Command, Control, and Battle Management and Communications (C2BMC) for Ballistic Missile Defense (BMD). PSI proposes an innovative architecture designed to leverage sensor diversity and multimodal feature extraction to provide Enhanced C2BMC functionality in search, track, discrimination, and kill assessment (KA) functionality. The key challenges addressed by the approach include data fusion, feature extraction, mitigation of pointing error and platform bias, management of the co-registration and co-association of disparate (ABIR/OPIR/radar) sensors, and addressing practical communications limits. The proposed objectives of the Phase I effort include the development of optimized cueing for stressing multitarget engagements (emphasizing the development and coordination of the new roles of ABIR and OPIR sensors in ascent phase track acquisition), and the development and simulated demonstration of a joint IR/radar feature-aided tracking system (for enhanced situational awareness during stressing multitarget engagements, and to enable earlier engagements with high successful kill probability). Both Engage on Airborne Infrared and Engage on STSS are initiatives targeted for enhancement using the proposed work, as is the PTSS program.

Title:Sensor Fusion Dynamic Scenario Descriptor
Abstract:Radiance proposes to design, implement and test multi-sensor (RF/IR/Vis) multi-platform data fusion algorithms, advancing the state of the art in Rao-Blackwellised Particle Filter (RBPF) algorithms in a dynamic Bayesian network framework. Our innovations provide a multi-sensor (RF/IR/Vis), multi-geometry picture of threat scenarios for C2BMC’s requirement for a single integrated picture of the battlespace. Our algorithms adapt with knowledge from one sensor applied to networked sensors, adapting with changes in operational environments and threats. Our algorithms offer potential enhanced performance and risk reduction for C2BMC and Ballistic Missile Defense RF and EOIR sensor elements. The data fusion algorithms we propose provide robust adaptation to changing physical environments, with seamless fusion of disparate and diverse sensor data, including diverse engagement geometries. RBPFs capture non-linear behavior with Particle Filter techniques integrated with linear algorithmic approaches where appropriate, resolving issues associated with traditional Particle Filter techniques, most significantly those due to particle depletion. The network will fuse data from multiple RADAR, airborne Electro Optical Infrared (ABIR-like), and satellite-based EOIR (PTSS-like) systems. We provide a Proof-of- Principle, demonstrating functionality and the ability to generate a multi-geometry, multi- sensor realization of the scenario that can adapt with network sensor data.

Title:Integrated Target Characterization Suite Using Multi-Sensor Fusion
Abstract:MDA plans to use optical platforms, such as PTSS, ABIR, and SM-3, to track ballistic missiles in support of ascent phase intercepts. For success, there are a number of system level challenges that the C2BMC element must overcome. A few of these are: 1) achieve and maintain stereo tracks, 2) perform lethal object discrimination, 3) prioritize and assign lethal targets to interceptors, and 4) handover lethal object information to the interceptor in a form that will allow it to identify the lethal object on its focal plane. The objective of this proposed effort is to: 1) use SysTRAAK, ExoAnalytic’s BMDS end-to-end simulation, to demonstrate these challenges on MDA’s ability to close the fire control loop in a complex ascent phase scene and ultimately intercept the lethal payloads, 2) develop algorithms to meet these challenges, drawing upon our base of existing TRL 2-6 algorithms developed during MDA/DV funded efforts over the past 10 years, and 3) deliver the algorithms to MDA for insertion into the C2BMC element. This proposal will investigate using radiometric information to enhance the probability of correct handover with demonstrations focused on ascent phase intercept.

Title:PMHT Track Fusion for ABIR
Abstract:Fusing data together for target tracking is a complex problem. There are two elements: First, the raw observations must be associated with existing tracks or used to form new tracks. Once the association has been done, then the tracks can be updated and filtered with the new data. When associating data (either measurements or tracks or both) with existing tracks, the separation between the tracks is critical to how difficult the association decisions will be. If the tracks are widely separated then the association decisions can be relatively easy. On the other hand, when the tracks are closely spaced the association decisions can be very difficult or nearly impossible. At any rate, these and other concerns roil the current battle space for ballistic missile defense. This proposal will explore the fusing of ABIR data from a few sensors in order to provide to the C2BMC a reliable and consistent set of tracks. We are proposing to solve this problem by using a probabilistic Bayesian approach with the Probabilistic Multi-Hypothesis Tracker (PMHT). Using a probabilistic approach will mitigate the computation numerations that occur when there is significant uncertainty in association decisions.

Title:Sensor Data Fusion
Abstract:Use of data from multiple sensors provides the opportunity for improved ballistic missile defense (BMD) search and tracking. Algorithms for combining multi-sensor data are required. BMD sensor data fusion is a challenging problem because of incompatibility in coordinate systems for different sensors, which makes it difficult to transfer variance and covariance information, and because of sensor registration issues, which result in measurement errors with a consistent bias. To overcome these difficulties, we propose using a root-mean-square (RMS) approach. The RMS value of a possible missile trajectory expresses the amount of consistency between the measurements that the possible trajectory should generate, and the actual measurements. The Marquardt-Levenberg optimization method can be used to find the trajectory with minimum RMS, which can be used as the fire control solution for that missile. Sensor bias can be resolved, allowing registration errors to be corrected. Furthermore, an output of the Marquardt-Levenberg algorithm is a covariance structure on the parameter set that defines possible missile trajectories.

Title:Sensor Data Fusion
Abstract:MDA seeks to maximize the utility of collected sensor data through a fusion architecture that provides an integrated view of the battlespace. IAVO proposes research and development of a fusion architecture, which employs novel algorithmic techniques using a foundation of sound stochastic theory, probabilistic inference methodologies and pattern recognition techniques to develop the iView2TM (Integrated Battlespace Viewing for Threat Discrimination and Sensor Fusion) solution which will: • Use all data collected from multiple sensors through an intelligent fusion architecture to ensure all available data is married to detected objects in space, decrease data redundancy and focus on presenting the most relevant information for quick and accurate target assessments; • Account for the uncertainty and disparity in gathered intelligence; • Incorporate historical data from previously collected intelligence about threatening objects to make more informed decisions; • Characterize object types and natures based on collected and derived intelligence, using the fusion architecture as the medium through which data is combined and viewed; • Use trajectory information to create a back-tracking capability to determine threat origin and compare missile characteristics against known weapon technology and potential end-phase targets to provide support for countermeasure decision-making; • Provide actionable intelligence for planning appropriate countermeasures.

Title:Sensor Data Fusion
Abstract:The MDA mission requires the use of data fusion to obtain accurate and persistent tracks of threatening objects discriminated from debris/countermeasures in order to provide an integrated picture of the battle space as well as fire control solutions to interceptors. A wide variety of information may be available for integration, including multiple sensor measurements, features, and track states; combining all these can improve track identification, association and accuracy, especially in the challenging MDA environment. Toyon Research Corporation proposes a dual-layer solution for data fusion for both short- term individual measurement associations and longer-term track-to-target associations. A Multiple Hypothesis Tracker (MHT) will be used in conjunction with a Bayesian network to model feature information and possible inferences in a way that promotes improved measurement-to-track association. Toyon’s Fusion and Correlation for Tracked Object Retention (FACTOR) system will handle track fusion and feature database management/track stitching algorithms. The FACTOR system has been tested and validated in other environments and will be adapted for the MDA picture, and a semi- supervised learning algorithm to help fuse features will be added. Toyon will design a test scenario with multiple short- and medium-range attacks from multiple launch sites in order to test these algorithms.

Title:Sensor Resource Management
Abstract:Torch proposes an innovative data fusion approach based upon a processing and communications architecture which supports a real-time Sensor Resource Management (SRM) driven demonstration of enhanced Track Quality (TQ) for BMDS System Track. Our approach is based upon our experience with the development of real-time networking and sensor algorithms which support significant improvements in TQ based upon the testing and management of sensor resources to enhance track accuracy. Our sensor level TQ models are driven by radar and optical sensor bias model state and covariance estimates coupled with sensor measurement precision and track models. Torch real-time SRM data/message support within our architecture will facilitate the prioritization and transmission of sensor cues to handle the dynamic launch and intercept environment leading up to key functions such as kill assessment. To support a short term planning cycle capability, Torch will address SRM computational loads via the proper choice of sensor, system, and feature based performance models in addition to the use of highly efficient assignment algorithms in a parallel processing architecture. Our Phase I work plan focuses on the implementation of our prototype real-time SRM architecture as well as establishing appropriate sensor resource models and network messaging to demonstrate an improved TQ.

Title:Optimal Sensor Resource Tasking to Support Global Battle Management
Abstract:This proposal addresses the problem of sensor resource management, and specifically focuses on the tasking of sensor resources at the battle management level. The term ‘sensor tasking’ as used here refers to the assignment of a sensor to a given task requirement. The task requirement may be in support of an engagement, and will typically be assigned to a specific time window within which the task should be performed so that the information obtained will support engagement planning and execution. Sensor tasks are evaluated to determine their impact on overall mission level objective using an innovative utility-weighted, information-based analysis. Sensors are paired to tasks based on a sensor- task analysis, which assesses both the feasibility and availability of a sensor to perform a specific task. The analysis will also provide metrics by which a given sensor-task pair can accomplish the objective of the task. Depending upon the resources available, multiple sensors may be candidates to perform a given task, and an optimal assignment will be performed based upon the sensor-task analysis metrics and a sensor management objective.

Title:Efficient Sensor Management for Optimal Multi-Task Performance (ES-MaTe)
Abstract:Knowledge Based Systems, Inc. (KBSI) proposes to investigate innovative methodologies and algorithms for Efficient Sensor Management for Optimal Multi-Task Performance (ES- MaTe), The goal of the proposed research is to investigate an efficient sensor resource management method for sensor scheduling specific to tasks required by a missile defense system. The Ballistic Missile Defense System uses multiple disparate and spatially separated sensors for multiple simultaneous tasks such as target search, detection, acquisition, discrimination, target tracking. Each of these tasks consists of minimization of uncertainty in estimation of some underlying stochastic process. However, sharing of resources with other tasks results in some degradation of the estimation performance. ES-MaTe will develop a constraint optimization technology for non-myopic multi-sensor scheduling that will ensure some level of minimum performance for each task by imposing performance constraints based on uncertainty measurements, while maximizing the total information gain. A feature of the optimization problem includes the imposition of several types of task specific sensor utilization constraints. The optimal non-myopic sensor scheduling requires dynamic programming that becomes unpractical due to complexity arising from combinatorial explosion. Approximate dynamic programming techniques will be investigated for practical implementation.

Title:Performance-Based Sensor Resource Management for Missile Defense
Abstract:Toyon Research Corporation proposes to develop a sensor resource management (SRM) algorithm that generates schedules that assign sensors to specific tasks, chosen to best protect numerous defended areas from multiple raids. We cast the problem of SRM as a combinatorial optimization problem and our algorithm assembles multi-sensor schedules from a set of candidate sensor tasks to minimize an objective function. The formation of candidate takes into account such constraints as availability, accessibility, and measurement capabilities. The objective function combines elements of information theory with measures of site survivability to quantify the mission objective. We solve the optimization problem using a branch-and-bound technique to generate good schedules quickly. This Phase I study will build on work we have performed in the area of SRM for over ten years and develop the extensions and modifications that will make it ideal for the problem of multi-raid, multi-target environments. Specific tasks we will pursue include development of sensor task creators and a suitable objective function, implementation in software, and demonstration of the effectiveness and computational tractability on an example problem. In Phase II we will integrate our software prototype with a sophisticated simulation framework and demonstrate our algorithm against more challenging problems.

Title:Unified Control-Theoretic Multi-Raid Sensor Management Algorithms
Abstract:Detecting, localizing, identifying, tracking, and intercepting multiple and dispersed missiles aimed at multiple and dispersed defended areas, presents a daunting theoretical and practical challenge. The Scientific Systems Company, Inc. team proposes a foundational, information-theoretic and controltheoretic approach. It is based on mathematically modeling a multiplatform-multisensor-multitarget system as SINGLE, JOINTLY EVOLVING STOCHASTIC PROCESS. All relevant information regarding behaviors of all sensors, all platforms, and all targets are inherently integrated into the algorithm design at the outset. As a consequence, all major functions—data fusion, search, detection, localization, identification, tracking, sensor management, and weapons assignment, are inherently integrated into a single, unified system. Our approach is based on the following innovations: (1) multisensor-multitarget likelihood functions that incorporate all relevant information about sensors; (2) dynamic “tactical importance functions” that mathematically specify the meaning of Target of Interest; (3) intuitively meaningful and statistically based sensor management objective functions; 4) Markov transition densities that contain all relevant information about target and sensor dynamics; and (5) integration of these concepts with approximate multitarget filters. Because it is information-theoretic, our approach selects multisensor dwells, versus short dwells, versus frequent revisits, versus sustained dwells, depending on which will optimize total information. It is also “myopic” rather than “farsighted,” since mismatch between motion-prediction models and actual multitarget motion tends to make the latter approach insensitive to rapid change. The project team includes Dr. Ronald Mahler of Lockheed Martin. Lockheed Martin will provide both technical and commercialization support in the application of the advanced Sensor Management Algorithms.

Title:Sensor Resource Management
Abstract:Today’s Ballistic Missile Defense networks consist of many different types of sensors and platforms, and given the expanded focus of MDA on theater and regional missile defense where multiple “raids” can be launched from different sites toward numerous targets, it is crucial that they can be dynamically tasked and deployed effectively in real-time to realize their full potential in achieving overall mission objectives. Effective cooperative use of multiple sensory sources requires development of algorithmic strategies to optimally manage these resources, subject to constraints, in order to provide the best quality of service to the weapon systems. To meet these aims, the Edaptive Computing team proposes SMAART, which will result in innovative, robust, commercially viable, real-time sensor resource management algorithms and software. The advantages of our algorithms over more standard approaches include their robustness to uncertainty, scalability, and their ability to operate in real time for complex scenarios. Through our innovative algorithms embedded into a flexible and intuitive sensor system simulation framework, SMAART can facilitate the development of robust and effective sensor resource management systems, and potentially other complex decision making applications.

Title:Resource Allocation using Market-Based Optimization (RAMBO)
Abstract:Missile defense takes place in a dynamic, uncertain environment. Multi-raid attacks threaten to overload sensor capabilities, leaving fewer sensor resources free to observe each target complex. Moreover, the shift in emphasis toward early intercept, coupled with the growing importance of short- and medium-range threats, reduces the time available for detection, tracking, and discrimination, because engagement decisions must be made more quickly. These factors increase the need for effective sensor resource management to squeeze the maximum amount of useful information out of an overloaded sensor network. What is needed is a solution that can optimally assign a large number of heterogeneous sensors to a large number of incoming threats fast enough for early intercept, while meeting dynamic constraints on sensor availability and physical constraints. Here, we propose Resource Allocation using Market-Based Optimization (RAMBO), to provide dynamic planning and scheduling of sensors to maximize sensor quality of service while minimizing sensor uncertainty. This approach applies market-based optimization, using solutions from economic theory and game theory, to sensor resource management by creating an artificial market for sensor capabilities and information. With a properly designed market, we can engineer a system that ensures an optimal allocation of sensors and resources.

Title:End-to-End BMDS Strategic Communication Systems
Abstract:To meet the goals of SBIR topic MDA 10-003, Welkin Sciences proposes to upgrade three important tools needed by DoD's strategic communications community: 1) the CommLink computer simulation used to analyze and evaluate scintillation hardening techniques by DoD scientists and contractors early in a transceiver's development cycle; 2) the CommLink Defined Transceiver (CDT) used by DoD contractors as both a rapid prototyping hardware platform and a rack-mount software defined radio system; and 3) the Configurable Link Test Set (CoLTS) fading channel simulator used for developmental, acceptance and production testing of scintillation-hardened communication systems. These three products need only be enhanced to support the goals of large bandwidth and multiple carriers explicitly described in the topic description. The current capabilities of CommLink, the CDT and CoLTS satisfy the other goals addressed in the SBIR topic description, and these capabilities will all be retained in the upgraded implementations.

Title:GPS and Command Link Assured Operation
Abstract:Echo Ridge proposes to develop a comprehensive realtime emulator capable of synthesizing a wide variety of waveforms such as GPS, interferers, and other GNSS signal classes. The system would create an arbitrary number of coherent wavefront RF output channels, synthesize atmospheric and terrain induced perturbations, and emulate propagation affecting phenomena resulting from plasma effects and EMP, and signal manipulation based on 6- DOF receiver motion sensing. The emulator will be based on a platform developed through Air Force and Army Phase I and II SBIR funding entitled DYSE, or Dynamic Spectrum Environment emulator. DYSE has been developed to address similar emerging test needs through the following key attributes including: emulating RF environments by converting RF to/from digital samples, and synthesizing RF sources and environmental effects in the digital domain between multiple physical and virtual systems under test; employing real-time signal processing functions carried out on PC-based CPU, GPU (Graphics Processor Units) and other hardware acceleration; applicable to a very broad variety of RF system development and testing, including communications, radar, jamming, navigation, and cognitive radio; emulating time-varying system platform motion and dynamics, and their effects at the RF level.

Title:Wavefront Simulator for 21st Century
Abstract:With the rapid strides in various avionics-related technologies, the need for advanced simulators will increase. Anti-jam receiver development and future improvements in PNT are critically dependent on the availability of advanced simulators. The needs include: flexible, accurate, adaptable, programmable, user-friendly, hardware in the loop operation, precise wavefront simulation, high dynamics, environment and jamming simulation, etc. The simulator for the 21st century will have to precisely accurately represent various environments ranging from urban canyons, nuclear and plasma effects for the complete wavefront. Large update rates and significant processing power are required. A navigation simulator with these features and capable of generating all current and future signals (CA, P, M, L2C, L5, Jammer waveforms,GNSS, etc.) is proposed. CRS has developed a modern wavefront simulator for all GNSS signals.This proposal details adapting the simulator to meet MDA objectives and optimize the system for cost/performance ratio. This system will be capable of multi-satellite, multi-interferer real- time RF output for multiple antennas. It will be capable of integration with a variety of other hardware simulation tools and GPS receivers. The proposed approach will leverage CRS’s current capabilities and expertise and will result, at the end of Phase II, in a fully functioning working system

Title:High-Bandwidth, Extended Linearity, Reaction-Cancelled, High-Surface-Figure-Accuracy Fast-Steering Mirror for Future MDA Missions
Abstract:Jitter suppression and image stabilization require an increasing number of technological improvements as vehicles become unmanned, more agile and work in more hostile environments. Fast steering mirrors (FSM) play an important supporting role in providing a quiet operating platform. LHDC has contributed a number of FSM for space platforms and plans to enhance performance of future products in four primary areas: 1) bandwidth, 2) surface figure accuracy over temperature, 3) highly linear operation and 4) low residual reaction torques. Higher bandwidth improves disturbance rejection and low residual reaction torque maintains a quiet optical bench during acquisition, tracking, and pointing, however aggressive the position and acceleration commands may be. Image quality and pointing accuracy are maintained over the wider operating temperature ranges. Inventory hardware is to be used to achieve an unusual amount of progress. This SBIR program is primed to lead into product development that will benefit a wide variety of MDA applications.

Title:Demonstration of High-Frame-Rate Wavefront Camera for Acquisition, Tracking, and Pointing
Abstract:Radiation-hardened, highly sensitive wavefront sensors (WFSs) with at least 256×256 resolution and the capability for sustained operations at 10 kHz are necessary to support the high-speed control loops used for image stabilization and jitter suppression in MDA systems for airborne and spaceborne targeting, tracking, scoring, and ranging. To satisfy this need, in Phase I, InGaAs avalanche photodiode (APD) arrays in 32×32, 128×128, 256×256, and 512×512 formats will be fabricated and characterized. Several small-sized arrays will be hybridized to existing WFS ROICs, with variable gain, low-noise preamplifiers, detector gain-uniformity correction, fusing, and pixel readout circuits. Low-noise operation will be demonstrated at 10-kHz frame rates by integrating the APD focal plane array (FPA) into camera electronics and a mechanical housing designed and fabricated in the Phase I program. Features of the camera will include a user-programmable processor, Gigabit Ethernet communications, and multiple LVDS wire and fiber outputs. The results of the Phase I WFS camera demonstration and characterization will be used to design a radiation- hardened multiple-output 256×256 format WFS ROIC, which will be fabricated and integrated with high-responsivity APD arrays, and the larger-format, high-frame-rate WFS camera will be delivered to MDA for further qualification.

Title:High Speed Infrared Sensor for Jitter Correction
Abstract:For laser tracking applications, a sensor with a high frame rate and sensitivity to infrared wavelengths is required. Aerius proposes to make a 256x256 sensor with a frame rate of 10 kHz. The sensor will include a detector array made from InGaAs so that it is sensitive to wavelengths from 800 nm – 1700 nm. The full receiver (sensor and interface electronics) will provide location and amplitude data on the laser beam of interest. Aerius’ proposed sensor is also scalable to 512x512 in future versions but still using the same core developed for the 256x256. This 512x512 sensor would also have a frame rate of 10 kHz, but it would only output the data of interest rather than the whole array. The receiver developed during Phase II will provide location data to the control system in order to control the steering mirrors. In Phase I, Aerius will demonstrate high frame rates on a 128x128 sensor.

Title:Acquisition Tracking and Pointing Technologies
Abstract:Applied Technology Associates (ATA) proposes the development of the stable platform for a new Optical Inertial Reference Unit (OIRU) titled the Space Qualified MSTAR Inertial Reference Unit (MIRU-SQ). The components and functions of an OIRU can be easily split between the stable platform and electronics subsystem. Because of the expensive nature of space qualified design, purchasing, and testing, ATA proposes for this SBIR project to focus on the stable platform design of the MIRU-SQ. The stable platform (also sometimes called the sensor head) contains many of the critical components for a successful OIRU. The electronics subsystem design effort is being proposed under solicitation topic MDA 10- 030. ATA’s proposed advancement to the current state-of-the-art is critical for achieving the Missile Defense Agency’s (MDA) acquisition, tracking, and pointing (ATP) goals, because, to date, no small and fully integrated OIRU has been designed or built for space applications. Given our more than 10 years of experience in developing one-of-a-kind OIRUs and 35 years focused on precision, sensing, measurement, and controls, ATA is uniquely qualified to deliver the innovations necessary for successful design and development of this critical element for meeting MDA’s needs.

Advanced heat sink technology enables increased performance of directed energy solid state lasers. Efficient high performance thermal management materials representing next generation thermal expansion matched high thermal conductivity heat sinks are proposed with an additional level of hybridization: active coolant channels embedded during the manufacturing process. Three stages of heat sink hybridization are offered: 1) Particulate diamond reinforced Al engineered for CTE matching the laser-diode semiconductor (to minimize interfacial thermal impedance). By designing the internal interface between diamond particulates and the Al matrix alloy, isotropic thermal conductivity approaching ~600 W/mK (2.5 x OHFC Cu) is expected. Since the Diamond/Al composite is CTE matched to the solid state laser, a solder bonded low thermal impedance interface is enabled. 2) Diamond preforms will be hybridized with MMCC’s commercial milled graphite fiber MetGraf preform and co-infiltrated to form a low cost high efficiency heat sink/spreader. 3) For further hybridization, stainless steel or Kovar tubes will be embedded within the preform prior to pressure infiltration casting. When post-cast connected to a fluid or refrigerant cooling system, high capacity thermal transport from very small heat sinks is possible.

Title:High Temperature, High-Efficiency, Vertical-Cavity Laser Diode Pumps for Directed Energy Applications
Abstract:Aerius Photonics is proposing to develop Vertical Cavity Surface Emitting Laser (VCSEL) arrays that are capable of high-efficiency (>55%) at high temperature operation conditions (60 C). At the end of Phase II, a 12 kW solid-state pump module will be delivered. The high temperature efficiency performance of VCSELs is critical in realizing fieldable diode laser pump arrays for high energy lasers and directed energy systems relevant to the MDA. The high temperature efficiency will result in considerable size, weight, power consumption, and cost reductions over what has been demonstrated to date. These modules will initially operate at 808 nm, optimized for Nd:YAG, but the overall technology approach will be applicable to wavelengths from 780 through 2.2 um. Additionally, the VCSEL arrays will demonstrate environmental ruggedness and reliability in harsh conditions, such as in dust, condensation, shock and vibration, high optical feedback, and radiation.

Title:Direct-to-Metal Bonding for Improved Thermal Performance of Lasers
Abstract:The most promising and scalable high-power laser geometries effectively manage thermal transfer from the laser crystal to the heat sink. While next generation crystals and pump geometries aim to eliminate waste heat in the first place, it will always be the case that efficient removal of heat will be paramount for further power scaling. When powers reach the kilowatt level, in an area about the size of a penny, heat removal is the roadblock. Soldering represents the current state-of-the-art, but still has relatively low thermal conductivity and challenges with matching thermal expansions. Various thermal compromises occur, even for the best currently-available thermal attachment methods. Precision Photonics Corporation has recently demonstrated a process – Direct-to-Metal Bonding – that can replace soldering or gluing as the thermal attachment method for certain high-power lasers, and enables higher thermal conductivity interfaces for many other applications, also. This Phase 1 effort will provide detailed characterization of that process, and validate functional laser devices using this thermal attachment method via measurement of thermo-optic aberrations.

Title:High Energy Solid State Laser Components and Subsystems
Abstract:The goal of this proposed Phase I effort is to design, construct, and demonstrate a novel laser gain element that can be scaled to operation at power levels in the 10s to 100s of kilowatts in a light-weight, compact, and rugged design while maintaining very high efficiency, high brightness, and good beam quality. This goal will be accomplished through the construction of a composite thin disk gain element pumped using a novel geometry to insure uniform pump distribution across the active lasing region and will operate with very low quantum defect and hence minimal thermal load. This architecture is expected to be scalable to very high powers while minimizing thermal effects that limit the ultimate performance of such devices.

Title:High Flux Cooling System for Solid State Lasers
Abstract:Solid State Lasers, high power microwaves and other future Directed Energy Weapons (DEWs) are notoriously inefficient, typically converting 20 percent or less of their input energy to useful output, with the remainder requiring removal in the form of heat. In most cases, the devices must be paused while the waste heat is removed. Weapon unavailability is the war fighter’s nemesis. Also perplexing: Today’s heat removal systems are bulky/heavy, and for high power systems, consume trailers full of equipment. These limitations hinder DEW development and battlefield acceptance. Mechanical Solutions, Inc. proposes a game-changing reduction in cooling system weight and size – perhaps 100 to 1 or more. Key innovations: A) Refinement and application of an advanced method for transferring waste heat from the laser diodes to a commercially available and commonly used refrigerant; B) A refrigerant vapor compressor that combines several innovative technologies, resulting in a miniaturized device with performance far superior to alternative compression methods. Successful development will enable higher power, more compact, lighter devices. The direct result will be wider DEW use, including those on smaller, more efficient transporters that can be rapidly deployed into more situations, so that these devices can become an increasing part of our nation’s defense.

Title:Compact, Ultra- Narrow-Bandwidth, High-Power Diode Laser Pumps for Diode-Pumped Alkali Lasers
Abstract:The diode pumped alkali laser (DPAL) allows for a potentially scalable approach towards a MW-class high energy laser system. By using an alkali vapor gain medium, one overcomes the intrinsic thermo-optical limitations of more conventional diode-pumped solid state laser (DPSSL) media. High spectral brightness diode pump sources are proposed as the enabling element for efficient, kW-class DPAL systems. We propose to develop a compact, ultra-narrow-bandwidth (< 1 GHz), high power diode laser pumps for DPALs. The ultra- narrow pump diode lasers will be designed in Phase I to provide kW-class power levels with spectral linewidths in the range of 500 MHz. In Phase I, a proof-of-principle demonstration will be performed. In Phase II, a kW-class narrow linewidth DPAL pump laser will be constructed. This combination of power, spectral linewidth, and compactness is not available in any other pump laser today. In addition, our approach is traceable to a very compact pump size and weight, which is a key driver for DoD applications.

Title:Spectrally Narrowed Pump Diode Arrays for Diode Pumped Alkali Lasers
Abstract:Diode-pumped Alkali Lasers (DPAL) have recently gained attention as highly-efficient lasers due to the very small energy differences between the pump and lasing levels (2% for Rb and 5% for Cs). Pump arrays with narrow spectral outputs with linewidths below 0.2 nm and which can be accurately tuned to Rb or Cs absorption lines are required, but conventional arrays have spectral widths as wide as 10 nm. Linewidth narrowing methods using Volume Bragg Gratings provide limited tunability, limited spectral locking, poor manufacturability and high cost but, maybe most importantly, do not provide a realistic path towards power levels and volumes required for tactical operations of HEL. We propose to develop very narrow linewidth, temperature tunable 780 nm pump arrays using novel on-chip wavelength stabilized high brightness diode arrays. This design provides very narrow linewidth, high power output and ease of temperature tunability in a monolithic, easily manufactured low cost diode array that is scalable to hundreds of kW level.

Title:Wavelength Stabilized High-Power Diode Lasers for Alkali Atom Pumping
Abstract:This Phase I SBIR proposal is submitted to address the needs of researchers needing high power narrow spectral linewidth diode laser pump sources for alkali vapor lasers. Diode- pumped alkali vapor lasers (DPALs) can be most efficiently pumped with spectrally-stabilized laser diode arrays (LDAs) with very narrow linewidths (a few GHz.) This allows DPAL operation at lower pressure as well as increased efficiency due to optimized absorption of the pump energy. With an efficient optical pump source, DPALs have the potential for scaling to kilowatt (KW) or megawatt (MW) power levels for industrial and military applications. A main hurdle to achieving these power levels has been the availability of high-power narrow spectral linewidth laser diode pump sources. Photodigm proposes an alternative method for diode laser stabilization based on newly emergent Guided-Mode Resonant Filter (GMRF) mirror technology. These mirrors possess both wavelength and angular selectivity with narrowband spectral linewidths as low as 1 GHz achievable. GMRF mirrors are presented as an enabling technology to realize scalable narrow-linewidth wavelength-stabilized laser diode pump sources for DPAL applications. The availability of these high-power spectroscopic pump sources would also find use in industrial and medical applications such as laser machining and spin-exchange optical pumping (SEOP).

Title:Novel, High-Power, Pump-Signal Fiber Combiner
Abstract:Recent advances in fiber lasers have shown their potential for power scaling to Directed Energy levels. Many of the high-power, cladding-pumped, large-mode-area fiber systems demonstrated in the laboratory have employed free-space optics to couple the diode laser pump power into the pump cladding of the fiber. While the approach is useful for power scaling demonstrations, it is not practical for operational lasers in terms of both reliability and ruggedness. High power, all-fiber pump combiners replace free-space optics for pump insertion and allow construction of “all-glass” fiber lasers. In the Phase I work proposed here we plan to fabricate a prototype of the only, to the best of our knowledge, end-pumped combiner configuration that allows almost any signal fiber to be used, including the same signal fiber used in the laser.

Title:Feasibility of Long Wavelength Infrared Focal Plane Arrays Based on Type-II Superlattice Minority Electron Unipolar Architecture
Abstract:Recent development of Antimonide-based Type-II superlattice infrared detectors has resulted in significant breakthroughs in terms of device performance as well as FPA imaging quality. Improvement in material quality and processing technique, as well as evolutionary modifications in device architecture have demonstrated the advantages of the material system over alternatives, and proven it as a viable candidate for the next generation infrared imaging. Yet, the performance of this material system has not reached its limits. In this project, we propose to further build upon the gap-engineering capability of Type-II superlattices to develop novel quantum device architecture called Minority Electron Unipolar Photodetector (MEUP). The design is a hybrid between conventional photoconductive and photovoltaic detectors and can benefit from the advantages of both configurations. The novel device architecture is expected to achieve high quantum efficiency while decreasing the dark current and the associated shot-noise. Material growth will be realized on 3” GaSb substrates and optimized for highest quality and excellent uniformity across the wafer. Applying it to LWIR FPAs in Phase II, it is expected to achieve a quantum efficiency above 60% and a dark current density below 1 uA/cm2 at operating temperatures higher than 65 K.

Title:Characterization and Reduction of Elcetrically Active Defects in Type II SLS Detector Materials
Abstract:Maxion Technologies proposes to adopt and further develop a metrology system tailored to understanding the nature of electrically active trap states in type-II SLS IR detector materials, and demonstrate the utility of the technique as a tool for MBE material optimization. Capacitance transient spectroscopy (CTS) is a unique diagnostic technique in that it directly measures the properties of electrically active traps such as their concentration, capture and emission rates, activation energies, and it also distinguishes between majority- and minority-carrier trap types. It is spectroscopic in the sense that it can resolve the signatures from multiple traps within the same material. CTS has proven to be a powerful diagnostic tool for mature semiconductor materials such as Si, GaAs, InP, etc., but it has not been effectively utilized for type-II SLS IR detector materials. CTS has the potential to significantly improve the ability to relate device growth processes directly to the generation of defects that contribute to high dark current and limit photogenerated carrier lifetime. We will use CTS to quantify type-II SLS material quality and subsequently improve detector material quality by better understanding the nature of the defect states and their relation to MBE growth parameters and SLS interface layer treatments.

Title:1Kx1K Longwave Infrared SLS FPA - Development and Cost Model
Abstract:We propose to develop a large-format 1Kx1K longwave infrared focal plane array (FPA) from Type-II InAs/(In)GaSb strained layer superlattice (SLS) photodiodes. In Phase I, we will develop small pixels with the goals of ~ 10 micron cutoff wavelength, quantum efficiency > 60%, and dark current density < 1e-5 A/cm^2 at 77K in a backside-illuminated FPA configuration. These metrics will be measured as a function of pixel size for different passivation schemes. Phase II will apply these developments to realize a 1Kx1K FPA. We will also develop a cost and yield model in Phase II and refine it with actual data in order to be able to predict the cost/pixel for SLS FPAs as a function of volume - a key metric for the commercial viability of both SLS technology and the horizontal business model for FPA manufacturing.

Title:Materials Development for Long Wave Infrared Focal Plane Arrays with Type II InAs/GaSb Superlattices
Abstract:In the proposed effort, SK Infrared LLC (SKI), a spin-off from the Krishna INfrared Detector (KIND) laboratory at the University of New Mexico (www.chtm.unm.edu/kind), in collaboration with Raytheon Vision Systems (RVS) and Intelligent Epitaxy Inc (Intelliepi) is proposing a systematic study with the following two objectives. (a) Optimization of the epitaxial growth parameters to reduce dark current noise, decrease growth defects, improve uniformity and increase device reliability and reproducibility (in collaboration with Intelliepi) (b) Explore novel detector architecture that leverages the bandgap engineering flexibility of the superlattice absorber combined with the barrier engineering capability of the 6.1Ĺ semiconductor family and integrate them into FPAs (in collaboration with RVS) As a part of this effort, the advances made in the improving the epitaxial growth procedure will be transitioned to Intelliepi and advances in the heterostructure design and FPA fabrication will be transitioned to RVS. The KIND lab has recently purchased a $1.35M Veeco Gen-10 MBE reactor with Sb and As valved cracker source capable of highly uniform growth on 3-inch wafers. SKI will have access to this reactor through the user facility at the Center for High Technology Materials (CHTM). In particular, we will explore a double-unipolar barrier design called PbIbN. The double- barrier heterostructure design (PbIbN) belongs to the family of band gap engineered SLS architectures, such as nBn , M-structure , W-structure , and complementary barrier infrared detector (CBIRD) . The improved performance of these SLS devices over the homojunction SLS detectors is credited to reduction in dark current by use of current blocking layers either in conduction or valence bands which reduce one or several dark current components. The PbIbN design further reduces noise in SLS-based detectors, since it contains wider bandgap potential barriers in both valence and conduction bands. In PbIbN detector design, the electron blocking (EB) layer sandwiched between P contact layer and absorber region blocks the minority carrier diffusion (electrons) current from P contact layer into the absorber region. Similarly the hole blocking (HB) layer blocks minority carrier diffusion (holes) current from N contact layer into the absorber region. Moreover, the electric field drop across the active region is small as compared to a conventional PIN design since there is significant amount of field drop across the EB and HB layers, which have a wider band gap compared to the absorber region. This reduction in electric field leads to very small depletion region and hence reduction in the Schockley-Read-Hall (SRH) generation-recombination component of dark current. The tunneling currents are also reduced due to significant reduction in field drop. Thus the device can be made diffusion limited over wide range of operating temperatures, thereby improving the performance of the device.

Title:Smart Infrared Focal Plane Arrays and Advanced Electronics
Abstract:Observing faint objects moving at a distance as well the “man behind the burning tank” requires both a high maximum signal level and a high dynamic range. A simple, yet game changing approach, the distributed analog-to-digital converter (Distributed ADC), provides nearly unlimited upper signal level without corrupting the noise floor at low amplitudes. This will add 3 bits of resolution and improve the signal to noise ratio (SNR) by 18 dB. The Distributed ADC described is very important in the context of shrinking unit cells, as there just is no space to accommodate a large capacitor. The target deliverable for the proposed program is a 1k x 1k MWIR digital-ROIC with 32 on-chip ADCs and with a buttable architecture that is rad hard (> 300 krad and SEE immune). Target unit cell size is 15 microns. Nu-Trek is collaborating with L3/Cincinnati Electronics (CE), a leading supplier of IR cameras, to provide a direct commercialization path. In particular, the proposed innovations are slated for an upgrade of one of the NightConqueror cameras. Nu-Trek is setting aggressive Phase I goals, and will leverage work in progress to tape out a chip containing representative circuitry in Phase I.

Title:Ultrasensitive and Compact Superluminal Ring Laser Accelerometer for Inertial Navigation
Abstract:For many applications, there is a need for developing inertial measurement units (IMU), employing gyroscopes and accelerometers, with better accuracy and/or smaller volume and weight. Currently, in partnership with others, we at Digital Optics Technologies (DOT) have been developing a superluminal ring laser gyroscope (SRLG) that can improve the accuracy of rotation sensing by nearly five orders of magnitude. Alternatively, for a given accuracy need, the SRLG can be very small. Recently, we have identified an architecture via which the same superluminal mechanism can be exploited to produce an accelerometer with similar enhancements. Here, we use this approach to offer to develop a superluminal ring laser accelerometer (SRLA). When compared to a conventional accelerometer, the SRLA can also be nearly five orders of magnitude more accurate, with a sensitivity of 10 pico- g/Hz^(1/2), while occupying a very small volume. The focus of Phase I would be to demonstrate the technical feasibility of the SRLA. Miniaturization and radiation hardening would be addressed in Phase II. The work proposed here is a collaboration between DOT, Aegis, and Vescent. Dr. Selim Shahriar, inventor of the SRLG and SRLA, is the founder of and chief scientific adviser at DOT. He will coordinate the overall effort.

Title:High-Performance Nonlinear Compensator for Next-Generation Fiber Optic Gyroscopes
Abstract:Fiber-optic gyroscopes (FOGs) are used as the fundamental building block for high- precision inertial and angular displacement sensors in applications ranging from missile and UAV to war-plane and satellite navigation. The nonlinearity-induced non-reciprocity in FOGs is recognized as the critical impairment limiting the obtainable sensing accuracy and precision. In effect, the entire three-decade-long development path of FOG is primarily Kerr- effect non-reciprocity mitigation, thus enabling improved precision navigation instrumentation in each subsequent generation of angular displacement sensors. We propose to develop the first true nonlinearity compensator in a robust, miniature-sized platform, fully compatible with the existing FOG technology. In this program, we will perform in-depth computational modeling, based on proven theoretical frameworks, that will be quantitatively validated and benchmarked by experiments in a state-of-the-art research facility. Successful completion of this program will result in calculation of the ultimate performance limitations of the proposed design, derivation of the engineering rules governing practical operation of the nonlinearity compensator, and a baseline design for a Phase II program.

Title:Development of Type-II Superlattices for Two-Color Focal Plane Arrays
Abstract:High performance single-band focal plane arrays (FPAs) are sometimes unable to discriminate a target from its background when they present similar infrared radiation at a given wavelength – which may occur even if the temperatures of the objects are different. Two-Color FPAs offer an additional wavelength that allows easy identification in such cases. Large-format dual-band FPAs are highly needed for next generation military applications. Current FPAs (eg. HgCdTe or Quantum Well Photodetectors) face fundamental and technological challenges when aiming for this new requirement. Type-II superlattices have been proposed as a viable technology and have already shown equivalent or better performance in single color detectors. In this project, we propose to continue the development of Type-II superlattices with Phase I demonstrating dual-band detectors based on Type-II superlattices, with equivalent performance as the state-of-the-art single color devices. The work will also consider the compatibility of dual-band Type-II superlattices detectors with large format ROICs designed and developed for dual-band FPAs. The development of material growth for large size wafers and of fabrication procedure for two- color arrays will also be addressed in this Phase I program to demonstrate the viability of Type-II superlattice technology. In Phase-II, 512x512 or dual-band FPAs will be delivered.

We will also engage with a Systems Prime in Phase II so as to ready the FPA and packaging for a systems level test following Phase II.

Title:Dual-Band Focal Plane Arrays with Double Unipolar Barrier InAs/GaSb Superlattices
Abstract:In the proposed effort, SK Infrared LLC, a spin-off from the Krishna INfrared Detector (KIND) laboratory at the University of New Mexico (www.chtm.unm.edu/kind), in collaboration with Raytheon Vision Systems (RVS) is proposing to develop a dual band based imager using a novel unipolar heterostructure design with Type II InAs/GaSb strained layer superlattice detectors. The dual bands that are chosen for this application are midwave infrared (MWIR, 3-5 m) and the long wave infrared (LWIR, 8-14 m). However, these devices can be designed for different wavelength bands to suit the application needs of the customer. The dual band detectors will be developed using a novel double unipolar barrier design called “PbIbN”. The advantage of the 6.1Ĺ family of semiconductors (InAs, GaSb and AlSb) is that it provides the device designer tremendous flexibility to control the valence band and conduction band offsets between the absorber and the barrier layers. The PbIbN device that will be investigated as a part of this proposal utilizes an electron barrier at the PI interface and a hole barrier at the IN interface. The unipolar barriers prevent the diffusion of minority carriers from either side of the absorber. Moreover, since the field drop is lower across the absorber region, the generation- recombination (GR) and tunneling currents are also reduced. The goal of the Phase I effort will be to demonstrate a single pixel PbIbN detector with dual band (MWIR/LWIR) operation with temporally simultaneous and spatially collocated detection. The Phase I option effort will transition this to an 8x8 array bonded to a fanout to determine the uniformity and reproducibility of the back-side illuminated devices. The Phase II effort will involve the demonstration of a 512x512 focal plane array in collaboration with RVS and their insertion into the Ballistic Missile Defense System (BMDS).

Title:Integrated Thruster Technology for Lightweight, High Performance, Compact LDACS
Abstract:Ultramet recently demonstrated rapid, reliable, and repeated ignition of hydroxylammonium nitrate (HAN)-hydroxyethylhydrazinium nitrate (HEHN) monopropellant mixtures. HAN- HEHN green monopropellants offer many improvements over monopropellant hydrazine and NTO/MMH bipropellant, including increased specific impulse and density specific impulse, as well as greater safety in terms of toxicity and insensitivity, which will significantly decrease overall propulsion volume, mass, and cost. Before this milestone was achieved, the feasibility of using advanced ionic liquid monopropellants was distant. The goal of the proposed project is to integrate the ignition system and thruster into a single component that will eliminate the need for an injector, thereby reducing the system part count, cost, mass, and length vs. L*. Based on existing technologies, in Phase I Ultramet will design and build an engine appropriate for a kinetic kill vehicle divert and attitude control system. In Phase II, this engine would undergo hot-fire testing using AF-315e monopropellant at Aerojet or AMPAC- ISP, both of which have expressed interest in the technology. Because the thermal bed is non-discriminate to the propellant, a different formulation or propellant type may be substituted. For example, the technology could be used with hydrazine or another monopropellant to increase performance and minimize thruster length.

Title:Composite DACS Nozzle for Next Generation Interceptor
Abstract:Fiber Materials Inc. (FMI) has developed and delivered carbon fiber reinforced silicon carbide (C-SiC) composite nozzles and thrust chambers for solid and liquid/gel fueled divert and attitude control systems (DACS) to Aerojet. The C-SiC material system has been validated with 3700°F solid propellant. The proposed program will address identified barriers to transition of the material system and position C-SiC composite material technology for use with the emerging next generation SM-3 Block IIB interceptor. The C- SiC system will facilitate a shift from current refractory metal construction technology to a ceramic matrix composite design with increased pressure capability with lower mass. This added capability will enable higher performance DACS designs and is applicable to other interceptor systems. In Phase I, FMI teamed with a prime contractor, will review the thermal-mechanical database. The critical component design properties with the lowest margins will be identified. FMI will build C-SiC materials from the current baseline carbon fiber as well as from a domestic source to assess the viability of replacing fiber type at the beginning of the Phase II program. Phase II will complete the building of a statistical database with multiple sample lots tested and fabricate Block IIB components for hot gas demonstration.

Title:Fast Response ACS (FRACS) for Interceptor Booster Stage Separation Control
Abstract:During missile staging, large unexpected torque loads have historically been problematic in causing periodic flight anomalies and in some cases catastrophic flight failures. As compared to typical requirements for booster Attitude Control Systems (ACS), the staging loads are short in duration, < 1 sec, and up to 10x in magnitude. This large difference in ACS requirements has developed a need for a dedicated lightweight, low cost, and highly reliable booster staging ACS. To address this need VTS is proposing a new Fast Response ACS (FRACS) that uses Electric Solid Propellant (ESP) propulsion system. The ESP propulsion system is ignited, extinguished and throttled with electricity without the need for pyrogen or explosive squibs. ESP’s are also inherently insensitive, non-toxic and environmentally green throughout the manufacturing and operation.

Title:Radiation Hardened Interceptor Avionics for Ascent Phase Interceptor
Abstract:The Space Micro team proposes to dramatically reduce the Size, Weight, and Power (SWaP) of a rad hard miniature image processing system (MIPS) for MDA interceptors using a combination of techniques. We are building upon and leveraging our existing heritage space hardware used for TacSat2 imaging, and our ORS-1 image processing system. The system evolving from this SBIR will meet MDA goals for advanced ascent interceptor avionics: 1. Miniaturized by factor of 10X 2. Radiation hardened to HAENS Level 2 3. Tie in with MDA prime contractors, (e.g Raytheon Missile Systems) in Phase II, and beyond 4. Dramatically reduced lead time based on standard product offering 5. Lower cost due to increased use of advanced COTS ICs and a small business overhead structure

Title:Rad-hardening Technology for Interceptor Avionics RaTOA
Abstract:The goal of the proposed research is the development of a radiation-hardened gyro that reduces SWaP (size, weight, and power) and cost and demonstrates improved performance of ascent phase intercepts. During this effort, NextGen and Gray Research (formerly GH Systems, Inc.) in partnership with RMS will provide designs, recommendations, and a risk mitigation plan for radiation-hardening the avionics package on an ascent phase intercept with a focus on the gyro and the SM-3 Block IIA and Block IIB as the intended platforms. The team will assess conventional and next generation gyros such as Honeywell's GG1308, GG5200/5300, and IFOS' G*Sense-SMF_A1-G1. The team will investigate the feasibility of rad-hard protecting the selected gyros with GH Systems avionics rad-hard packaging technology. During the Phase I option period an operational prototype that demonstrates radiation-hardening of a gyro and associated sub-components will begin. The TRL during Phase I will be elevated from a 2 to a 3. During Phase II, the design, fabrication, and testing of a gyro sub-system prototype will be accomplished further elevating the TRL to a 5.

Title:Nuclear Event Detector for Radiation Hardened Interceptor Avionics for Ascent Phase Interceptor
Abstract:The objective of this research and development effort is to encourage the genesis of innovative, high performance avionics systems, subsystems, and components that will enhance the capability of successfully achieving early intercept missile defense in current and future interceptors in a hostile environment. Specifically, we propose to develop a nuclear event detector and circumvention controller (NEDCC) system that will be used onboard the BMDA interceptor missile. Nuclear event detectors (NED) are a key part of military electronic systems whose components are susceptible to damage from transient gamma or X-ray radiation. An effective nuclear event detector must first detect the transient radiation. At a pre-determined threshold of transient radiation, the NED must generate appropriate control signals to circumvent or shut down the critical circuitry that would be damaged or destroyed by the transient radiation. To optimize the performance and reliability of the NEDCC, two options will be pursued during the Phase I program. The lowest risk option will include a silicon chip with CMOS analog and digital circuitry along with an external P-I-N detector diode. In addition, AET, Inc. is proposing to research the technology for a monolithic silicon chip containing an internal P-I-N diode or an onboard diamond sensor.

Title:Compact, Low-Cost Inertial Rate Sensor for Ascent Phase Interceptors
Abstract:Ascent Phase interceptors require lighter weight, smaller, more robust and lower cost avionics components that can withstand stressing launch conditions and severe radiation environments without compromising their performance. In particular, rate sensors for Inertial Reference Units (IRUs) that can provide high-resolution Line of Sight (LOS) stabilization, more accurate inertial pointing and higher bandwidths needed to support planned early intercept avionics systems. IFOS, with a team having many years of pioneering experience in Fiber-Optic Gyroscopes (FOGs), radiation hardening and mitigation of vibration effects proposes developing an advanced FOG that will ultimately be able to withstand radiation as well as the high shock and vibration that accompany launch, yet be able to deliver tactical grade pointing accuracies at kHz data rates. IFOS will exploit innovative techniques including new fiber components, coil production methods, robust packaging and advanced signal processing techniques that would allow the substantial reductions in weight and volume of interest to MDA. Phase I will focus on design and demonstration of a proof-of- concept FOG with improved bias drift and other desirable performance features that is compatible with robust packaging, leading to a Phase I option where RH and vibration shielding aspects will be further analyzed and detailed.

Title:Rad-hard damage-resistant Self-healing Synergistic KV (RISSK)
Abstract:The ultimate goal of the proposed research is the development of radiation-hardened damage-resistant self-healing synergistic interceptor or Kill Vehicle (KV). The synergistic structure will be made multifunctional by moving the Guidance System (GS) electronics and the missile harness-fairing assembly into the skin of the interceptor/KV composite skin. NextGen teams with Gray Research in partnership with Raytheon Missile Systems to determine the feasibility of developing a synergistic structure with NextGen's structurally integrated sensor and antenna technology; Gray Research's rad-hard technology to protecting the avionics package and other components of the interceptor/KV; RMS' Integral Missile Harness-Fairing Assembly concept that replaces conventional wire harness designs with an integrated approach; and NextGen’s advanced composite skin technologies including damage-resistant and self-healing missile skins. The TRL during Phase I will be elevated from a 2 to a 3. The 4 technologies previously discussed will lay the foundation for the research and development effort in Phase II. The radiation hardening, migration of components and electronics into the skin as well as the advanced composite skin technologies will be improved. A 2-year follow-on Phase II award such as an enhancement phase will allow further development with the goal of further increasing the TRL to 5.

Title:Advanced Synergistic Structures and Materials for Interceptor Kill Vehicles
Abstract:Phase Four of the Missile Defense Agency’s Phased Adaptive Approach will include the deployment in 2020 of a land based Aegis missile to provide early intercept capability, called Next Generation Aegis Missile (NGAM). The first step in the NGAM development is the Technology Development Phase in FY11-13. For that phase, MDA has identified several technology needs for meeting the next generation requirements. One of the technology needs is higher performing liquid upper (or third) stage. To address that need, San Diego Composites, Inc. (SDC) is proposing a program to develop a lightweight liquid upper stage (LUS). The programmatic objective of the program is to demonstrate risk reduction and provide prototype hardware for consideration by the prime contractor for inclusion in the NGAM Technology Development Phase. The technical objective will be to demonstrate, through hardware fabrication and test, advanced metal forming and composite overwrapping manufacturing methods to reduce mass of a propellant tank for a NGAM liquid upper stage. Phase I will be subscale and Phase II, if invited, would be full scale. The objectives of this SBIR proposal are designed towards maturing the lightweight liquid upper stage propellant tank technology to TRL 5 at the end of Phase II.

Title:Tightly Integrated Multi-Functional Fiber-Optic Sensor Sub-Systems for Advanced Interceptor Kill Vehicles
Abstract:Intelligent Fiber Optic Systems Corporation (IFOS) proposes to demonstrate the feasibility of integrating cutting-edge fiber-optic sensing technology with the next-generation interceptors. The overall objective is to increase the performance and capability of the KV. Fiber optics has the potential to significantly contribute to this objective since it inherently offers ultra-light-weight, ultra-compact, and multi-functional solutions capable of reliably (radiation-resistant and EMI-immune) operating under harsh space environments. IFOS proposes to design an integrated Fiber Bragg Grating (FBG) sensor and Fiber-Optic Gyroscope (FOG) sub-system, construct a proof-of-concept high-speed miniaturized FBG- FOG prototype, and test the integrated platform. The design will enhance both endo- atmospheric and exo-atmospheric performance and capabilities and lower size/weight/power (SWaP), wiring harness, and lifecycle cost. The system prototype will demonstrate proof-of- principle and the corresponding test results will provide proof-of-functionality of the proposed integrated sensor sub-system for the seeker and interceptor. IFOS will develop a Phase II strategy plan, with MDA’s permission in collaboration with MDA’s prime contractors, based on the confines of SM3 2A&B systems, that includes system development and integration strategy and potential demonstration opportunities. While the FOG part of the solution can be incorporated with the existing systems, the total FBG-FOG subsystem is geared more towards the next-generation systems.

Title:Active Sensor Technologies for Interceptor Seekers
Abstract:Advances in compact lasers operating at 1 to 5 microns that require minimal or no cooling during fly-out timelines are required to support future MDA missions. Packaging concepts that enable integration of the transmitter into spaces in and around existing passive detectors and optical elements are highly desired. High peak power short pulse lasers that can switch to high pulse repetition rates for target imaging are also desired. The target acquisition ranges require lasers that can fit within the current interceptor available space and still generate significant pulse energy and repetition rates to achieve the desired operating ranges. Scalable architectures that lead to increased operating ranges are highly desired. Laser configurations must be inherently thermally and mechanically stable over extreme temperatures, shock, vibration, and must be capable of operating in high radiation environments. Areté Associates proposes a disruptive new ultra-compact and efficient laser technology called AIRTRAC that promises to meet these stringent requirements. The AIRTRAC configuration combined with Areté’s “coffin” athermal gain module dramatically reduce size, weight and power (SWaP) requirements on severely constrained platforms. AIRTRAC’s self-aligning, dimensionally stable cavity configuration is extremely robust over harsh environmental conditions. Areté will develop proof-of-concept hardware in Phase-I, and will develop, build and test an ultra-compact AIRTRAC prototype in Phase-II that will achieve > 100 mJ/pulse at > 100 Hz pulse repetition rate.

Title:High Speed, Radiation Hardened Focal Plane Array (FPA) for Hybrid Coherent and Direct Detect Active Imaging Receivers
Abstract:Currently, Readout Integrated Circuits (ROIC) are not available that can support hybrid active imaging receivers that have dual mode direct detection and coherent detection capability. In addition, radiation hardness / survivability of electronic components is of paramount importance for use in the Ballistic Missile Defense System (BMDS) programs. Components must function reliably when exposed to radiation from space and nuclear events. The goal of this effort is an ROIC that addresses both requirements at the Missile Defense Agency (MDA). The ROIC will be designed with increased levels of resistance to damage induced by nuclear environment radiation with minimal impact to performance. This will be accomplished by using Radiation-Hardened-By-Process (RHBP) and Radiation-Hardened- By-Design (RHBD) techniques. This effort will also develop the novel ROIC circuitry specifically aimed at hybrid-mode active imaging detection. This will be accomplished through the development of a Software Defined ROIC (SDR) that can be digitally programmed in support of multiple modes of operation. In Phase I, performance requirements for the ROIC will be defined. The ROIC unit cell circuit performance will be simulated, and the floor plan of the ROIC will be established.

Title:Multi-Mode LADAR Camera Development for Enhanced Interceptor Seekers Readiness
Abstract:A flash LADAR camera will be designed and demonstrated in the Phase I program. After fabricating a series of high-gain, low-excess-noise, back-illuminated avalanche photodiode (APD) arrays, including 8×8, 32×32, 128×128, and 256×256 formats, the arrays will be hybridized to one or more existing flash LADAR readout integrated circuits (ROICs). After optical and electrical characterization, the LADAR focal plane arrays will be integrated into 32×32-element 20-kfps LADAR camera electronics, with three time-of-arrival and pulse amplitude samples per frame. The sensitivity and pulse-pair resolution of the camera will be demonstrated. In Phase II, the fill factor of the linear-mode APD arrays will be improved with integral microlenses, and the arrays will be integrated with a 128×128 ROIC to build a flash LADAR camera, allowing for field testing. Also in Phase II, the FPAs will be radiation, reliability, and lifetime tested. The benefits of the program are significant. Deliberate MDA investment in camera technology to increase the technology readiness level of linear-mode APD technology and ROICs, will prepare for future LADAR system upgrades, and significantly reduce program risk and cost, offering the potential for a very large return on investment for MDA.

Title:Anti-Tamper Technologies for Missile Defense
Abstract:FPGA devices provide a secure environment for execution of critical technology only if the configuration bitmap is kept from attackers. Side Channel Attacks (SCAs) may extract keys during AES-protected bitmap loading -- a serious problem for many anti-tamper system solutions. Accord proposes an SCA immune soft-processor as the crucial missing piece for providing tamper resistance during FPGA bitmap loading. Accord's CRIPTC processor inherently has a very high level of resistance to SCAs. In the proposed effort, Accord will analyze and benchmark test the CRIPTC Architecture’s SCA resistance. Using these results Accord will design specialized modifications to the architecture to increase its baseline resistance. In Phase I, Accord will implement selected changes and show initial benefits compared to the basic design. Comparison is also made with the FPGA manufacturer’s standard soft-core processor. A target scenario, protection for loading an FPGA with CPI content, will be the example case study. The Phase II design will produce a revised soft-core (SCAR-CRIPTC) to execute AES without detectable physical leaks, which Accord will demonstrate, benchmark and evaluate the SCA protection level.

Title:Optimized Thermal Battery for Weight- and Size-Constrained Applications
Abstract:Thermal batteries are a power source for most MDA weapons systems. Some of these systems have severe constraints on weight and size, and for this reason, advanced thermal batteries are needed that can provide greater power in smaller and lighter packages. The key components of conventional thermal battery cells are made by hydraulically pressing powders. Such components must be greater than a minimum thickness to keep the pressed powder pellets from breaking. For batteries that must supply high current for a relatively short period of time, this consideration can greatly increase the mass and length of the battery. We propose to address this problem by combining two recent advances in thermal battery technology. We will utilize a thin film component technology to construct thinner components with lower impedance than is possible with pressed powders. We will employ Erigo’s advanced thermal battery simulation software to extract the maximum benefit from the thin film process. By combining both technologies, we will create a well-defined procedure for building thermal batteries with greatly reduced mass and volume.

Abstract:The ballistic missile defense system (BMDS) has been established to protect the American people, their allies and troops deployed abroad. The mission capability and success of many of the elements comprising the BDMS are reliant on more efficient and capable portable power supplies. Aspen Aerogels proposes to develop next generation thermal insulation solutions specifically for use in primary reserve thermal battery applications. Optimization of material formulation and the utilization of a novel form-factor will allow for the development of an easily installable, highly flexible and durable insulation material with unsurpassed thermal performance. Utilization of these materials in thermal management applications will allow for more efficient thermal batteries with increased practical energy density, longer mission lifetimes and lower cost. Aerogel enhanced thermal batteries will thus have the potential to significantly augment many of the key elements currently being utilized in the BMDS.

Title:Ultra High Temperature Hafnium-based Materials for Propulsion Technologies
Abstract:Rhenium is the current material of choice for several critical hot gas path components of Divert and Attitude Control Systems (DACS) due to its erosion resistance, high-temperature strength and compatibility with propellant products. However, disadvantages of Re include high cost and high density. Alternatives to Re such as composites, refractory metal alloys, and monolithic ceramics have been proposed, but all possess strength, oxidation and/or cost limitations. Thus, the development of economical, reduced mass alternatives to Re for employment in oxidizing and rapid heating to temperatures above 2200°C (4000°F) remains a great interest. Cermets based on the Hf-Ta-N systems have been suggested, though few investigations of these materials have been conducted. Moreover, investigations that have been conducted were focused on uneconomical solid-state hot-pressing techniques. Plasma Processes proposes to employ vacuum plasma spray (VPS) technology in the exploration of cermets for DACS applications. The Phase I technical objective is to evaluate the microstructures and oxidation behavior of Hf-Ta-N cermets. Specifically, fabricated components will be characterized to identify microstructure, phase content and phase distribution. Micro-indent testing will be performed to pseudo-quantify the relative fracture toughness. Oxidation testing will be conducted to evaluate oxidation behavior. This proposed material development effort will be directly beneficial to upgrades for SM-3 and THAAD, as well as for new systems such Net-Centric Air Defense Element (NCADE).

Title:Manufacturing of Advanced Composites for Selected Propulsion Components
Abstract:Advanced CMC composites are currently being developed for various components in the propulsion system along the hot gas path, where pressures up to 3000 psi and flame temperatures from 4000°F to 5000°F are encountered. In order to achieve the lightest possible and optimal component design meeting both structural and high temperature operational requirements, both fiber preform and matrix material selections are critical. While the selection of matrix materials based mainly on material’s stability and ablation resistance at severe temperature is relatively straight forward, the creation of optimal fiber reinforcements is more complex. In addition to fiber selection and fiber placement, the practical manufacturing limitations are also important considerations. An optimized fiber preform should use the best fiber, oriented in the load direction and is producible. Imported needled fiber preform has been selected as a baseline for many CMC components. Needled preform typically offers low but relatively isotropic fiber distribution. They were originally developed and optimized for A/C brake and exit cone applications. These preforms are costly and require long lead time. Under this program, plan is proposed to develop domestically produced needled preform with optimized design for CMC composites allowing end user/ material designer to develop the best CMC composite achieving the lightest possible component design at affordable cost.

However, bulk rhenium is disadvantaged by being expensive and extremely dense. In order to reduce cost and weight of rhenium DACS components, a different approach must be considered. Rhenium-coated graphite can offer both superior erosion resistance and strength while reducing component cost and weight. During this Phase 1 investigation, PPI will team with ATK to design a nozzle/pintle combination based on rhenium-coated graphite. Using PPI’s innovative EL- Form™ technique, rhenium will be electrochemically deposited onto a graphite nozzle/pintle combination. Process parameters will be optimized to ensure a uniform coating is produced on all graphite surfaces. The optimized parameters will be used to produce a nozzle that will then be hot gas tested at ATK’s facility. During Phase II, the processing parameters will be further optimized with an emphasis on multi-component processing to reduce component costs. Re-coated graphite nozzle/pintle components will then be fabricated and hot fire tested in ATK’s DACS. A key target acquisition for this technology will be the SM-3 Block IIB DACS.

Title:Innovative Antenna Design and Materials for Lightweigting Next Generation Aegis Missiles
Abstract:The programmatic objective of the program is to demonstrate risk reduction and provide prototype hardware for consideration by the prime contractor for inclusion in the NGAM configuration and Trade Study program. The technical objective will be to demonstrate, through hardware fabrication and test, lightweight antenna substrate with integrated nanomaterial ground plane, antenna footprint design reduction, and lightweight antenna window technologies to reduce mass of the antenna assembly on the Guidance Section of the NGAM. Phase I will be subscale design, fabrication and test and Phase II, if invited, would be full scale design, fabrication, and test. The objectives of this SBIR proposal are designed towards maturing the lightweight antenna assembly technology to TRL 5 (at the end of Phase II) by “integrating the technological components with reasonable realistic supporting elements so that the technology can be tested in a simulated environment”.

Title:Materials and Life Cycle Sustainability for Structural Missile Applications
Abstract:This Phase I Small Business Innovative Research Program will develop and demonstrate the technology to produce large-scale, high temperature, lightweight composite missile structures for transition to a fielded weapons system where weight minimization and resistance to high temperature exposure is critical. Performance Polymer Solutions Inc.’s composite system has the ability to survive in extreme temperature environments where metals are traditionally utilized because prior to now, no structural composite system could survive. This novel matrix material, combined with high-performance carbon fiber and novel hydrophobic coating systems for composite moisture absorption prevention, will provide state-of-the-art composite materials with enhanced performance and weight reduction relative to super alloys and other traditional missile materials currently being used in ballistic missile defense systems. P2SI will demonstrate in this work the performance and manufacturing advantages offered by our material, coupled with the incorporation of a new fiber reinforcement and environmental barrier coatings, and will validate the necessity for its insertion into ballistic missile defense systems.

Title:Radiation Hardening Manufacturing Technology
Abstract:BMDS components must function reliably when exposed to radiation, including both nuclear weapon and natural space environments. Current tools will not allow correct evaluations of system performance. Since the current radiation environment tools were not designed to handle sub-orbital trajectories, environments have been calculated by interpolating from a number of satellite orbital trajectories. A fully integrated approach, utilizing complete ballistic solutions, is needed. In Phase I, ASI, teamed with Gray Research, will interface space environments codes with orbital and sub-orbital trajectory models in the Trajectory Interface for the Radiation Environments (TIRE). TIRE will produce an accurate trajectory, calculate the geomagnetic field transmission function and apply it to space radiation environment models. This approach will accurately model radiation exposure along sub-orbital as well as orbital trajectories, significantly improving estimates of the radiation environment to which interceptors are exposed , removing the need for multiple iterations, and reducing the computational time for any arbitrary trajectory. In Phase II, we will examine the integration of TIRE with nuclear weapon environments, advanced neutral and ion transport codes, and single event effect models to further enhance radiation hardening performance predictions of BMDS interceptors for a full evaluation of the radiation’s impact on a system.

Title:Radiation Hardening of Point-Of-Load (POL) Converters
Abstract:Due to growing defense and aerospace system complexity and associated power management and distribution schemes, there is an ever increasing need for high efficiency, Point-of-Load (POL) converters to replace the centrally tailored power distribution schemes of the past. Power conditioning approaches must address HAENS survivability requirements while responding to stringent interceptor and space-system sensor, avionics and electronics power conditioning needs. Further power solutions must deliver enhanced reliability as-well-as significantly improved size, weight and power (SWAP) performance. Meeting these demands requires HAENS survivable POL converters capable of supporting high input voltages and having the flexibility to deliver multiple, stable output voltages down to 1.2V. The above requirements can be met by hardening existing commercial products. The objective of this effort is to implement specific RHBD, non-invasive, RHBP and packaging techniques and electrical performance enhancement strategies to an existing Hi Rel commercial POL device, to achieve both improved conversion efficiency and HAENS survivability. Knowledge gained, can be applied to an existing family of commercial POL devices and will provide a wide selection of survivable power management devices to meet diverse and evolving missile defense power management requirements.

Title:Radiation Hardening Manufacturing Technology
Abstract:Commercial off the shelf (COTS) parts offer high performance and low cost and are favored in most military applications. Unfortunately, they are usually not rad-hard. One of the more practical approaches to preventing catastrophic failure resulting from the explosion of a nuclear weapon entails circumvention and recovery, which entails removing power from the sensitive COTS for ~ 1 s, just enough time to prevent the buildup of currents that would cause the part to burn out. To do so, a power-supply-circumvention-controller is required. Such a part is not available on the market and contractors build their own power supply circumvention controller out of discrete. In the proposed work, Nu-Trek will be developing the first commercial power-supply-circumvention-controller. The power-supply-circumvention- controller will disconnect the input power source, discharge the stored energy in all supplies, and remove the “crowbar” and reconnect the power source after the nuclear event clears. The Intersil fab is being targeted to part. A letter of support indicating Intersil’s interest in the part is included in the proposal. The availability of a convenient power-supply- circumvention-controller will facilitate the implementation of circumvention and recovery, an important and cost effective approach to radiation hardening.

There is no high density effective or cost effective NVM solution available to space electronics designers. DoD, NASA, and DTRA R&D investment funding of CRAM, MRAM, and FRAM at the major players (BAE Systems and Honeywell) over the past 10-15 years have not yet resulted in cost effective, high density, producible available space products.

Title:The Blow-down Large Angle-of-attack Signatures Thrust Termination Toolkit (BLAST3)
Abstract:In this SBIR, we develop a toolkit for computing time-dependent signatures for solid rocket motor thrust termination. The toolkit is composed of several modules describing the combustion chamber, near field, and far field flows, and outputs time-dependent spectral imagery. The fidelity of each module is user selectable between slower, higher fidelity simulations, and faster engineering approximations, and leverages several existing MDA plume simulation tools. The variation in flow composition and properties during thrust termination is highly complex, so the Phase I work features development of an engineering approximation of the flow leaving the combustion chamber during thrust termination. In Phase I, the model is used to initialize a continuum CFD code to compute the near-field expansion, and a DSMC code to compute the rarefied portion of the gas plume. Results are rendered for signatures and compared against data.

Title:Improved Thrust Termination Modeling for Solid Rocket Motors
Abstract:To improve the predictive capabilities of solid rocket motor end-of-burn phenomena, two analysis tools will be further developed. An existing engineering tool will go through continued development and validation, while an existing solid rocket ballistics model, built and demonstrated within a commercial CFD platform, will be expanded to allow for conjugate heat transfer between the burning grain and the motor internal insulation and casing. The CFD platform includes a coupled solid mechanics solver, allowing for tight coupling between the grain burnback and the motor gas dynamics. Addition of the internal insulation and motor casing should be direct application of existing modules. Development of a slag generation and subsequent particle tracking capability will enhance the existing tool.

Title:Advanced Chemistry and Radiation Modules for Wake and Reentry Flows
Abstract:The outcome of the proposed SBIR program will be the development of an innovative scientific testbed code suite for reentry vehicle signatures. The testbed will model all key physical hypersonic flow effects to a high degree of fidelity and will be validated against field data. It is intended that the scientific testbed code could be used as a benchmark to test lower-fidelity models, or could be used as an inexpensive substitute for laboratory or field tests. Chemistry, radiation, ablation, plasma effects, and other modules within this testbed code suite will then be interfaced to existing MDA simulation tools to create an engineering and applications code suite. By the end of Phase II, the engineering code suite will provide a validated, practical, and accurate end-to-end infrared and radar cross section simulation capability for MDA signature applications.

Title:Advanced Reentry Vehicle and Wake Models
Abstract:Missile defense systems like THAAD, GBI and AEGIS depend upon having prior knowledge of the signature characteristics of the threat missile in order to perform the necessary system functions to defeat the threat. Thus, the role of signature simulation (both radar and optical) technology is critical for this purpose. This SBIR focuses on the capability of predicting plasma effects on reentry vehicle hardbody signatures, as well as wake radar cross sections and optical signatures. The key Phase I technical objectives are to: (1) review MDA RCS and optical signature modeling needs relative to reentry plasma, compare to the existing simulation technology and identify gaps in knowledge and capability,(2) construct a Phase II plan for addressing those gaps in knowledge by combining or enhancing existing technology into deliverable signature simulation software and (3) demonstrate the feasibility of performing that technology integration for a problem of interest to MDA. Reentry vehicle optical and radar signatures are dependent upon a number of complex phenomena which must be accurately modeled.Examples of these phenomena include: vehicle shape and material construction, hardbody surface temperature, trajectory conditions (altitude, velocity, orientation), and details of the flowfield surrounding and behind the vehicle. These details include: local distribution of pressure, temperature, chemical composition, internal energy states, velocity and flow field turbulence quantities (length scale, turbulent energy and other fluctuating quantities).

Abstract:The goal of the activity is to increase simulation fidelity in predicting the fluid dynamics and plasma environment in the vicinity of reentry vehicle configurations. We begin with our current implementation of thermal equilibrium and non-equilibrium chemistry capability that includes the effects of finite rate chemistry with dissociation and ionization, catalytic wall treatment, general geometry capability, etc., and we will further enhance it. We also expect to develop a new model to help better predict turbulent flow in the boundary layer and wake including the effect of turbulence on the plasma environment. The enhanced capability will be able to fit into current end-to-end simulation processes that include relevant post- processing aspects.

Title:Advanced Reentry Vehicle and Wake Models
Abstract:At hypersonic flow conditions, the flow field around reentry vehicles is ionized, resulting in electro-optical emissions, detectable radar cross-sections, and attenuation of signals transmitted through the plasma. Ablative heat shields may further increase the levels of electrons in the plasma around the hardbody and in the wake. We propose to extend an existing high-fidelity computational fluid dynamics code to provide accurate flow field simulation data and to couple with existing signature prediction tools. This code, US3D, is a highly scalable implicit unstructured grid method designed for hypersonic flow simulations. It has been used successfully on a wide variety of reentry vehicles, and has a general thermo- chemical nonequilibrium kinetics model that is extensible to the modeling of complex reentry plasma flow fields. Key elements of the proposed work include the implementation of relevant chemical kinetics data for high-temperature air and ablation products, the development of an automated grid generation and smoothing tool for hypersonic reentry configurations, and the development of modules to provide properly formatted data for the existing MDA and DoD signature prediction tools. The resulting tool will provide MDA with a robust, efficient and extensible modeling and simulation capability for reentry vehicle radar cross-sections and optical signatures.

Title:Innovative Sensor Packaging and Testing
Abstract:Infrared optical systems are advancing rapidly. Infrared Focal Plane Arrays (FPAs) have grown from small single color scanning detectors to large two-color detector arrays. New materials and processes are improving IR system performance. But the transition from promising laboratory-based technology to fielded system is slow, due in large part to the low Technology Readiness Level (TRL) of the technologies. Often the transition is further hampered by a lack of standardized testbeds that could provide a way to quickly evaluate new technologies and move them into the field. To address this need, AOS proposes to establish a testbed using an existing modular design for an infrared dewar system as the core IR sensor hardware test platform, an FPGA- based sensor processor, and a computer-based test control console. AOS’s Modular Integrated Dewar Assembly (MIDA) has been manufactured as part of a previous SBIR project and the system is available to serve as the universal test set that will allow devices under test to be incorporated rapidly. Key to this testbed is our development of modular interfaces that use kinematic self-alignment techniques to provide repeatable zero-alignment interfaces. By implementing interfaces that comply with deterministic and repeatable component alignment standards, the MIDA allows parts to be easily interchanged with no significant redesign cost. Figure 1 shows the concept.

Title:High Speed Representation of Complex Scenes
Abstract:Simulation is used to safely test BMDS components and strategies in a controlled environment. FLITES uses physics-based modeling to accurately simulate hardbody and plume radiation. Currently, the processing resources required by this model limit the scene detail of the surrounding environment, which reduces the overall simulation quality. We propose to employ modern image generator technology to generate background scenes for FLITES. This rendering layer will interface cleanly to FLITES through an API. The background rendering layer will run as a distributed thread on a dedicated COTS processor so it will not impact the missile simulation performance, and be cleanly composited with the FLITES generated missile scene using techniques such as GPU shaders. The background scene generated by this new process will use physics-based rendering and atmospheric modeling, and a thermal solver will be used in conjunction with material and geometry databases to produce high fidelity background scenes in real time. A world wide database will be supported, with a location based paging mechanism to balance the system and scene load. Dynamic phenomena such as dynamic sea states and moving clouds will be added to obtain a realistic portrayal of the background scene.

Title:Visible and Infrared Scenes for Tactical Environments
Abstract:Higher resolution optical sensors are driving requirements for highly detailed representations of natural background surfaces and man-made objects for real-time scene generators used in development of Ballistic Missile Defense Systems (BMDS). New methods are critically needed to represent such structures that are computationally efficient enough for scene generators to support the high frame rates and physical accuracy required by the MDA mission. CPI believes this can be achieved through careful selection of key physics elements and contributors to scene signatures, as well as judicious choice of the spatial-spectral resolution for the scenario of interest. CPI proposes to accomplish this by developing Visible and Infrared Scenes for Tactical Environments (VISTE), a software product for generating background scenes using these ideas, and that seamlessly interfaces with existing scene generation tools such as FLITES. VISTE will support a user-friendly application programming interface to generate background scenes and run BMDS simulations for defined use case scenarios. The innovative aspect will be a robust integrated run-time framework that intelligently selects the resolution needed to generate high speed and high fidelity representation of complex scenes given user-supplied inputs. VISTE will be a stand-alone background scene generator and scene simulator controller, with visualization of the simulation results.

Abstract:We propose to define a dynamically reconfigurable photonics-based system to efficiently collect, down-convert, distribute, and selectively combine the return signals from multiple array elements to a set of digital processors. Electronic signals from the array elements will modulate optical carrier signals. With an appropriate choice of optical carrier signal and photonic architecture, the signals due to one target can be coherently combined while all other signals and noise combine incoherently. Using Compressive sensing one can recover precise position and tracking information of multiple targets from a massive array (40,000-400,000 equivalent elements) that permit the critical target information to be recovered from the processing of a relatively small number of signals

Title:Hardware-Compressive Photonic Multi-Beam Receive-Only Array
Abstract:Users of phased arrays with large numbers of elements (e.g., 40,000 to 400,000) wish to have the capability of steering multiple beams simultaneously and to maximize the array bandwidth and dynamic range. Optical fiber’s light weight, small size, and immunity to electromagnetic interference have motivated researchers to propose photonic techniques for steering large arrays. In Phase I of the SBIR program described here, Photonic Systems, Inc. proposes to use modeling and simulation software to evaluate the RF performance (e.g., dynamic range, array gain and beam shape as a function of beam position and of RF frequency – which determines the useable RF bandwidth – and isolation of receive signal beam ports from one another) of our hardware-compressive photonic multi-beam receive- only array architecture, and to design affordable experiments to test the model’s validity. With inputs from discussions with system integrator Raytheon Integrated Defense Systems (Tewksbury, Massachusetts), we will update the cost estimates shown in this proposal with much more rigorous analysis of expected hardware procurement and assembly costs to enable a clear, quantitative comparison of our hardware-compressive architecture to other candidate approaches.

Title:Multi-port Electro-optic Switch Architecture for Efficient Programmable True Time Delay Unit
Abstract:Recent broadband analog photonic link performance improvements have renewed the interest and activity in developing microwave photonics for broadband radio frequency (RF) signal transmission and signal processing. Increased bandwidths and reduced fiber optic link insertion loss/noise figure accompanied by increased dynamic range have created real insertion opportunities of advanced fiber optic signal distribution manifolds and RF photonic signal processors into antenna-based communications, radar, navigation, and electronic warfare systems. A key photonic integrated circuit module that enables many of the tunable microwave filtering and true-time-delay (TTD) signal processing applications is a low insertion loss, variable optical delay line with fast reconfiguration time. In this proposed effort SRICO will integrate the latest advances in electro-optic technology with low-cost, commercially available components from the telecommunications industry to produce a compact, photonic true time delay unit with faster switching, lower power consumption and wider bandwidth than competing systems. This innovative approach offers 50x reduction in voltage, sub-microsecond switching speeds compared to tens or hundreds of microseconds for bulk devices.

Abstract:In this SBIR program we will design, build, and deliver a phased array radar time delay unit (TDU) with unprecedented performance. The enabling innovation is a new photonics-true- time-delay (PTTD) architecture that will provide: larger delay tuning (up to 20 nsec), low insertion loss (< 2 dB), high bandwidth (> 10 Gbit), rugged monolithic construction with no moving part, and very low SWaP. Importantly, this approach will realize large time delay tunability and low insertion loss, all in a form factor that enables integration of many channels in a compact package. For example, we have designed a device that will provide 1000 channels in one monolithic “window-pane” like package (~70700.3 cm). This may be mounted directly prior to an antenna array. Finally, the simplicity of the approach enables low production costs.

Title:Wideband Scalable Multi-channel Digital Receiver/Exciter (DREX)
Abstract:The United States Missile Defense Agency (MDA) is searching for a software-defined multi-channel radar receiver/exciter that would provide improved performance and added flexibility over currently deployed radar systems. In response, MaXentric is proposing a system codenamed ACERR (Advanced Coherent Exciter/Receiver Radar). The ACERR system is composed of a hierarchy of analog front-ends, high-speed digitizers, FPGAs, and Manycore processors that can be reconfigured and scaled to fit the requirements of individual applications. The architecture lends itself to want to find the coherence across multiple wideband channels. This enables characterization of the effect of amplitude/phase imbalance on the performance of radar waveforms. ACERR will benefit the MDA with its high degree of flexibility in allowing many different radar algorithms as well as different beamforming structures, which will in turn greatly enhance ACERR equipped radar systems in their ability to acquire, track, and identify ballistic missile threats.

Title:Wideband Scalable Multi-channel Digital Receiver/Exciter (DREX)
Abstract:The needs of the modern battle field are driving ever increasing requirements for the “state of the possible” in system components and subsystems for modern and next generation RF system. In this topic we consider the functionality of a Digital Receiver/Exciter and our ability maintain calibration and coherence over a wide bandwidth and multiple channels. The overall goal of this topic is to develop an approach to calibrate and cohere multi-channel wideband Digital Receiver/Exciter (DREX). Matrix Research will modify existing in-house simulation tools to evaluate and document several coherence approaches and methodologies, develop an architecture, and identify technology challenges. Our approach is to work closely with the government throughout the project to ensure that the government’s requirements are captured. If the Option is awarded, Matrix will develop the preliminary hardware/firmware design.

Title:Wideband Scalable Multi-channel Digital Receiver/Exciter (DREX)
Abstract:Colorado Engineering, Inc. (CEI) proposes to develop techniques for calibrating and cohering multiple wideband DREX channels that are scalable, embeddable, and suitable for real-time implementation. CEI will leverage its expertise with radar systems, embedded hardware, and signal processing to research and define solutions that address amplitude and phase imbalances, group delay, and sample location uncertainty. Next generation Ballistic Missile Defense radars are slated to be based upon highly digitized sub-arrayed digital beamforming architectures and Multiple-Input, Multiple-Output radar technology. Both approaches require perfect calibration and coherency across channels to achieve their full benefit, but the physical reality is that hardware is never perfect, performance drifts over time and temperature, and therefore channels will not have identical phase and amplitude responses. Under this proposed program, CEI will research and develop techniques to calibrate and cohere multiple wideband DREX channels. The approaches will scale from a handful to hundreds of channels and facilitate embedded processing implementations with real-time performance. The effort will include the development of a parametric model of multichannel DREX imbalance and its effect on radar systems performance. The proposal project will also employ scalable, modular receiver/exciter technology developed by CEI under an MDA-sponsored SBIR Phase I/II as a test bed.

Title:Wideband Scalable Multi-channel Digital Receiver/Exciter (DREX)
Abstract:In response to the proposal solicitation of ``Wideband Scalable Multi-channel Digital Receiver/Exciter (DREX)', this proposal presents a phase-I research plan committing to provide a set of study and experiment results, and conceptual design of a scalable coherence method. A new framework for wideband DREX with digitalized channel mismatch compensation is proposed. In the proposed architecture, digital signal processing relies on both a FPGA based real-time processor and a host PC with Graphic Processing Unit (GPU) for parallel computing. Major considerations in system design, measurement based modeling, channel mismatch compensation, as well as performance evaluation are discussed. Among many challenges are 1) to develop an effective system identification technique for the proposed channel model and 2) to develop a feasible channel mismatch compensation technique based on global optimization. Typical applications in wideband digital beamforming (DBF) and MIMO radar will be considered in developing and verifying the new schemes. Indeed, there are many questions and uncertainties associated with modeling and implementing the new schemes in real-time, which motivates us to study feasibility and implementation related issues using our lab facilities. This way, investigation results will be more convincing, which will pave the way for the phase II development.

Title:Develop Accelerated High Power RF MEMs Switch and Phase Shifter Reliability Test Methodologies
Abstract:Active phased array radars are expensive and solid state power and low noise amplifiers are a major component of that expense. Phase shifters employing low loss, high linearity Radio Frequency (RF) Microelectromechanical Systems (MEMS) switches are an enabling technology for Electronically Steerable Antennas that can be employed for radar and Electronic Warfare applications. This program will develop accelerated reliability test methodologies for high-power ohmic RF MEMS switches and phase shifters. Current testing approaches are time consuming and costly and hinder acceptance of this technology by government programs. Radant will develop test conditions in Phase 1 and a lifecycle test system in Phase 2 that will accelerate the mechanisms of ohmic MEMS switch failure. The dominant root cause of failure is excessive adhesion force between the contact surfaces. Accordingly, in order to accelerate these failures, test conditions will be designed to increase contact adhesion. This will include examining the impact of increased contact power handling as well as increased contact force. The completed accelerated lifecycle test system can also be utilized to make full burn-in of devices more practicable, without degrading the performance of surviving devices.

Title:Lossless Tunable Filter for Space-Based Photonic Routers
Abstract:Aerius Photonics proposes to develop lossless tunable wavelength filters operating around 1550 nm based on electrically-injected MEMS-Tunable Vertical-Cavity Surface-Emitting Lasers (MT-VCSOAs). The unique properties of these devices simultaneously provide tunable wavelength filtering and optical gain, making MT-VCSOAs ideal components for filtering and forwarding optical signals in wavelength division multiplexed (WDM) networks. Aerius will leverage lossless tunable filters based on MT-VCSOAs to construct photonic routers suitable for space-based applications. The use of MT-VCSOAs as lossless tunable filters will allow signals to be routed without wavelength conversion and for the system to support both analog and digital signals. Implementation of electrically-injected devices ensures small size, weight, and power consumption. In Phase I, the tunable filters will be designed, fabricated, characterized, and evaluated for radiation tolerance. Aerius will also work to initiate development of the network topology and WDM photonic router architecture. Upon completion of Phase II, Aerius will deliver a prototype WDM photonic router utilizing MT-VCSOAs as the enabling technology.

Title:Space Photonics Technology
Abstract:Applied Technology Associates (ATA) proposes the development of the electronics subsystem for a new Optical Inertial Reference Unit (OIRU) titled the Space Qualified MSTAR Inertial Reference Unit (MIRU-SQ). The components and functions of an OIRU can be easily split between the stable platform and electronics subsystem. Because of the expensive nature of space qualified design, purchasing, and testing, ATA proposes for this SBIR project to focus on the electronics subsystem design of the MIRU-SQ. The electronics subsystem (also sometimes called the ECU or electronics control unit) contains the analog and digital electronic components, power conditioning and distribution, processing unit(s), and laser source. The stable platform design effort is being proposed under solicitation topic MDA 10-005. ATA’s proposed advancement to the current state-of- the-art is critical for achieving the Missile Defense Agency’s (MDA) acquisition, tracking, and pointing (ATP) goals, because, to date, no small and fully integrated OIRU has been designed or built for space applications. Given our more than 10 years of experience in developing one-of-a-kind OIRUs and 35 years focused on precision, sensing, measurement, and controls, ATA is uniquely qualified to deliver the innovations necessary for successful design and development of this critical element for meeting MDA’s needs.

Title:Space Photonics Technology
Abstract:This proposal offers an innovative laser communication system architecture allowing free space optical communications at high data rates in a way that is compact, light-weight, robust, vibration-tolerant, inexpensive, and eye-safe to be suitable for long range space- based applications. The proposed Scale Phase-locked Adaptive Communication Element (SPACE) laser communications system replaces conventional laser communication transceivers with a sparse array of synchronously-operated small-size adaptive laser communication (ALC) nodes. Each ALC node of the sparse array represents a fiber collimator in which precision adaptive beam pointing, beam tracking, and wavefront phase distortion correction capabilities are combined into a structurally integrated architecture without additional external wavefront control sub-systems. Each ALC node is capable for receiving and transmitting a laser communication signal compliant with SONET OC-48 wavelength grid and supporting from 4 to 64 channels at 2.5 Gb/s data traffic per channel with potential transitioning to OC-192 (10 Gb/s) standard rate. In the proposed innovative long-range laser communication system architecture the adaptive fiber-collimators play a “building block” role. These laser communication building blocks can be assembled into the SPACE system with different modular architectures to meet the specific requirements of various ballistic missile defense missions.

Title:Large Format Space Focal Plane Array Technologies
Abstract:Under a recently completed Air Force SBIR Phase II program, we demonstrated the initial feasibility of a back-illuminated p-on-n LWIR HgCdTe junction photodiode formed by diffusion of arsenic from a vapor source. This initial successful demonstration used a mesa format. Our proposed Phase I program will continue the development of the basic arsenic-vapor- diffused lateral-collection micro-junction process, extending the process to a planar architecture and to small-area junctions and demonstrate the overall feasibility of this new architecture, with the goal of achieving higher operability than the traditional two-layer mesa Very Long Wave Infrared (VLWIR) HgCdTe p-on-n devices achieve. Our Phase II program will further extend this work to large-format VLWIR FPAs and demonstrate improved operability in 512x512 arrays with 20x20 µm˛ unit cells. The combination of our novel methods and creative processing techniques is the key to the success for this new technology.

Title:Fast Wafer-Scale Characterization Techniques for CZT
Abstract:The goal of this proposal is to develop fast wafer-scale techniques for characterization of Zn-concentration and precipitates and inclusions of Cd and Te. A novel approach to spectrometry will be used to develop a fully automated system for generation of high resolution 2D map of Zn-concentration that promises to be 10x-100x faster than current spectrometers. Advanced image processing techniques will be combined with infrared microscopy to generate 3D wafer-scale map of precipitates and inclusions, as well as decorated line defects in the CZT wafer. These capabilities promise to improve qualification of starting substrates as well as relating performance of MCT detectors with features of the substrate. These tools also promise to provide valuable insight into and help optimize bulk crystal growth processes.

Title:Ultra Low Power, Radiation Hardened, Reconfigurable Analog-to-Digital Converter
Abstract:The goal of this project is to develop an ultra low power (ULP), radiation hardened, reconfigurable analog-to-digital converter (ADC) in the 130nm Flexfet Independently Double Gated SOI CMOS process. Satellites include a large number of sensors which perform both generic system functions and specific mission needs. For these various sensors, the required resolution for the associated ADC may be as low as 8-bits or as high as 22-bits while the bandwidth can range from a few kHz to several MHz. A new Hybrid Pipelined Delta-Sigma (HPDS) ADC will be developed as this particular hybrid architecture shows great promise with regards to programmability, reconfigurability, and radiation-immunity. Similarly, American Semiconductor’s Flexfet process is ideally suited for the design of rad- hard ULP, reconfigurable circuits. Flexfet transistors provide a wide range of dynamic threshold voltage adjustment which supports dynamic reconfigurability and performance tuning. The Flexfet technology provides an innovative solution for superior environmental characteristics to meet temperature and radiation tolerance requirements with ability to fine tune the power and performance for high levels of integration like a microprocessor. Implementing the HPDS ADC architecture in the Flexfet technology will provide a superior ADC solution for the unique requirements and environmental challenges of multi-year space missions.

Title:Advanced Rad Hard ADC for Satellite Applications
Abstract:Ridgetop Group will develop a novel, ultra high-resolution, radiation-hardened analog-to- digital converter (ADC) and digital-to-analog converter (DAC) for applications in servo control systems in satellites. The key performance attributes, including integral calibration circuitry, resolution of 18 bits, sampling rate of 2 MS/s and power consumption below 100 mW, will be achieved using a successive approximation register (SAR) topology that offers significant advantages over conventional methods. The embedded DAC in the SAR ADC makes use of the capacitor array topology and calibration technique used in the SAR ADC, and it has 18-bit resolution, a 10 MS/s update rate and < 20 mW power consumption. As modular building blocks for satellite servo control applications, the data converters are radiation-hardened to 1 Mrads of total ionizing dose (TID), have immunity to single event latchup (SEL) and single event functional interrupts (SEFI), and use radiation-hardening-by- design (RHBD) techniques to obtain sufficient tolerance to single event upsets (SEU) and single event transients (SET). Using the trusted foundry process (TAPO), the blocks will be essential library items for use in fast-track MDA programs where extremely high resolution and radiation-hardened performance are required.

Title:Radiation Hardened, Low Power, Variable Bandwidth/Resolution Digital-to-Analog or Analog-to-Digital Converters
Abstract:This proposed innovative research , code named ‘Chameleon’, will create an insystem field programmable ADC and DAC, both rad-hard and suitable for space and aeronautical applications. Converter designers have traditionally solved point problems– starting with a target resolution and bandwidth, and then optimizing power for that application. Power efficiency of these converters suffers significantly when they are operated at reduced bandwidth or resolution. The Chameleon approach begins with a unique and patented Sigma-Delta converter architecture which, by changing modulator coefficients, may be programmed to efficiently trade off bandwidth for resolution. By simultaneously addressing all five of the major determinants of converter performance: modulator coefficients, sampling capacitance, clock rate, bias current, and digital signal processing; this approach delivers an ADC and DAC which will maintain high power efficiency even while being configured across a wide range of bandwidth and resolution settings. The targets will be capable of resolution up to 22 bits and conversion speeds to 5 MSPS (million samples per second) The Phase 1 effort will examine the tradeoffs between broad programmability and complexity, as they affect feasibility, and will deliver simulation models consistent with the recommended structures. Following development phases will result in working silicon.

Abstract:The goal of the proposed work is to develop a single-chip, rad-hard, GPS receiver. Nu-Trek has designed and will leverage a 2-channel rad-hard (HAENS level 2) GPS receiver front- end in the proposed work. The front end will be combined with a Raytheon baseband digital signal processor (DSP) developed for the Miniature Air Launch Decoy (MALD) program. The key challenges to be addressed in the work are integrating all functions onto a single chip, achieving the low power requested (<75 mW) and radiation hardening the receiver to 300 kRad TID and single event effects. Nu-Trek and Raytheon’s proposed approach integrates all functions onto a single chip, reduces power to the state of the art through subthreshold operation of the circuits designed and employs rad-hard-by-design techniques in conjunction with a robust processing technology (Jazz’s 0.18um SOI process).

Title:Innoflight Miniature End Cryptographic Unit
Abstract:Encryption is a commonly overlooked critical technology especially for small satellites. A miniaturized, low-volume, low-mass yet flexible encryption unit is required for operationally- useful small missions. Currently, there are no Type 1 certified encryption units that are small enough for use on CubeSat-sized spacecraft, which greatly restricts the utility of the very small architecture. Innoflight is currently nearing completion of its first generation CubeSat encryption unit, the Compact Encryption Unit 100 (CEU100). In the proposed Phase 1 project, Innoflight will expand its development of miniature End Cryptographic Unit (ECU) technology for small satellite applications by developing a next generation design. The next generation Miniature ECU will include a number of key innovations, including: • High performance operation, including 100 Mbps full-duplex operation at less than 1W of required power and radiation hard to at least 100 krad. • The Miniature ECU will be implemented in as an independent daughter card (for certification purposes) at a target of 3" x 2" that can be integrated onto an existing radio or C&DH board to prevent the need for a dedicated crypto slice or package. • The Miniature ECU will have sufficient resources so that it can be used as the C&DH computer on a very small spacecraft as needed. • The Miniature ECU shall be capable of operating as in independent subsystem with the following features: operational mode configuration including over-the-air rekeying, support for variable s/c voltage, selectable input and output data rates, standard ciphertext and plaintext ports to support the vast majority of bus component hardware, and single event functional interrupt (SEFI) mitigation.

Title:Ultra-Compact Lightweight Elastic Deployable Roll-Out Boom
Abstract:DSS’s innovative elastic deployable Roll-Out Boom will provide revolutionary performance when compared to conventional state-of-the-art technologies, and will significantly enhance operations and capability for future MDA and DoD missions, including PTSS and STSS. The proposed technology is strong, stiff, lightweight, thin, compactly-stowed, scalable, affordable, and can be fabricated from ultra-lightweight composite or metallic materials, and in a broad range of cross-sections. The technology can be made magnetic, non-magnetic, conductive, or non-conductive, and can seamlessly integrate harnessing. The technology can be used as a self-deploying antenna, deployment and support for calibration sensors, electric field antenna, linear actuator, grapple arm, gravity gradient boom, camera support, inspection aid, or as an actuator/structure for deploying payloads, antennas, solar arrays, instrument benches, solar sails, and sunshades. The Roll-Out Boom technology employs an innovative deployment synchronization system to provide controlled, reliable and repeatable deployments in a known kinematic path. The technology provides exceptional structural performance in a small lightweight package, and is a direct replacement to current state-of- the-art systems. Boom sizes envisioned can be from 0.5-inch to 12-inches in diameter (or greater), with lengths from 0.25m to 50m long (or longer).

Abstract:Intrinsix proposes a low power, high-integration, radiation hardened software defined Global Positioning System (GPS) single chip solution. The phase I SBIR contract proposes two major components. First the proposed GPS receiver is a heterodyne Radio Frequency Sigma Delta Modulator (RF-SDM) that significantly improves performance over other integrated solutions by absorbing mixers and high selectivity filters into a specialized Analog to Digital Convertor (ADC). Second Intrinsix proposes the development of a flexible digital platform using the NASA Navigator GPS as a baseline. The phase I SBIR contract will focus on the validation of the RF architecture, architecting an extendable digital platform for signal processing and the methodology for radiation-hardening by design in a modern commercial sub-100nm process technology.

Abstract:Quallion LLC’s (Quallion) proposal responds to SBIR Solicitation No. MDA 10-034 entitled “Advanced Space Power Technologies”. In our response, Quallion is targeting an electrode development for “beneficial materials development for space-quality lithium rechargeable cells that enable them to accommodate higher energy densities(>200Wh/kg at the battery level); higher charge and discharge rates with suitable voltage characteristics”. Rate capability and energy density are determined by design configuration, and the materials in the battery. Even the inert components like current collectors and separators can contribute to losses in the available capacity and rate capability of the battery. Quallion proposes an electrode design that will reduce the overall internal resistance and increase the mechanical integrity of the electrodes. Phase I will identify an electrode design and process through physical, electrochemical analyses and cell tests. Phase II will further validate the process at a greater scale of manufacturing and large cell testing.

Title:Enhanced Spacecraft Survivability
Abstract:The AEgis Technologies Group, Inc. has developed innovative approaches to enhance the survivability of MDA Space Systems to spacecraft anomalies through the detection and characterization of laser radiation on spacecraft surfaces in real time. We are addressing the current inability to detect and characterize high energy laser (HEL) engagements on satellite targets. AEgis has developed novel sensors and instrumentation for HEL test and evaluation on ballistic missile targets that are very close to being able to meet the project requirements. We have demonstrated PbS quantum dot (QD)-based detectors that are capable of measuring irradiance profiles at wavelengths from 1.0 to 1.3 ěm. These sensor systems employ an open mesh architecture and micron-scale lithography techniques to achieve good spatial resolution with an extremely low profile that minimizes size and weight impact. High-speed electronics have been developed that allow sensor data acquisition speeds in the kHz range. The sensor system could accurately detect and measure laser irradiance up to 10s of kilowatts per square centimeter, while characterizing the beam in terms of wavelength and source location (terrestrial or space-based, based on satellite telemetry). Such data could be used to trigger defensive tactics or to characterize an attack.
