| Title: | Nanostructured Radiation Hard Optical Coatings for Star Trackers |
| Abstract: | During the proposed Phase I SBIR program, NanoSonic will fabricate novel multilayered self-assembled anti-reflective coatings onto the surface of space-based detector substrates that will impart improved durability and broadband transmission exceeding the current treatment technology. NanoSonic will demonstrate improvements to broadband transmission by targeting the desired waveband and optical transmission specifications. The requirements for this technology will demonstrate the utility of our patented electrostatic self assembly method, which can be tailored to provide an array of coating properties to a substrate of interest, with controlled thicknesses in the range of several to hundreds of nanometers, with minimal variation and exceptional surface roughness control. The anti-reflective coating of the detector aperture is subjected to a variety of damaging environmental conditions, including extreme temperature variations and exposure to solar radiation. This damage cannot be remotely repaired which renders the detector inoperable, thus unable to communicate accurate information to the interceptors. Substantial improvements to the current coating technology will elevate the performance of the detector and can be achieved through refined control of optical transmission through a longer wavelength, as well as enhanced durability, by employing the ESA method using select materials. |

| Title: | High Slew Rate Radiation Hardened Star Tracker |
| Abstract: | Optical Physics Company (OPC) is proposing to investigate a novel interferometric star tracker design with end-of-life measurement error of 0.13 arcseconds at a spacecraft slew rate of 2 deg/sec. The interferometer design is inherently rad-hard and athermal, easily capable of operating in the orbital temperature range (-65 to 65 degrees C) and radiation dose (300 krad). Furthermore the full star tracker has lost in space recovery capability similar to most high end star trackers. One proposed option adds an interferometric front end to a more traditional star tracker design, thereby building upon proven technology and leveraging the substantial investment in star trackers to date. The project will be conducted in cooperation with subcontractor Ball Aerospace in Boulder, Colorado, who will keep the technical goals aligned with customer needs. During Phase I a lab breadboard of the star interferometer with a white light simulated star source will be built and tested. In addition, an end-to-end analytic performance model will be developed and anchored to a wave-optic simulation of the system including radiation, thermal, vibration and slew disturbances plus data processing. The Phase I project will conclude with a blueprint of the Phase II prototype design and test plan. |

| Abstract: | Space Micro, teamed with SAIC and Octant, propose a high performance, rad hard star tracker based on proven CMOS APS device technology. The approach that the Space Micro team will use in developing and demonstrating a radiation hardened star tracker that meets the AFRL SBIR performance goals is to highly leverage and integrate existing R&D at all three companies. Combination of new CMOS APS sensor and camera,, Octant's "lost in space" LIS algorithms, and Space Micro's high performance DSP rad hard processing, enables breakthrough DoD star tracker performance. In addition to our baseline concept, we will monitor other DoD SBIR activities and insert if they appear to viable and producible. |

| Abstract: | Hittite proposes to develop a radiation-resistant, high-speed (> 2 Gs/s), high-resolution (12-bit), low-power (< 3 W) analog to digital converter (ADC) for satellite communications and other wide band digital receiver applications. No available ADC offers this combination of performance, power, and radiation tolerance. A combination of innovative design and advanced SiGe BiCMOS technology will be used to meet the performance and power goals in an ADC that is radiation resistant by design and technology. The ADC will reduce the size, weight, power, and cost of digital receivers by moving data conversion closer to the antenna, eliminating intermediate RF/IF stages. During Phase I a conceptual design will be developed and key cells simulated. Prototype ADCs will be designed during Phase II for use in satellites for the Air Force and other military and commercial applications. |

| Abstract: | Here we propose a compact tunable transmitter based on Azna's established directly modulated chirp managed laser (CMLT) technology that exceeds LaserComm requirements. The transmitter comprises a tunable directly modulated semiconductor laser and a passive optical spectrum reshaping filter. The tunable semiconductor laser is integrated with a semiconductor optical amplifier (SOA) to generate > 10 dBm output power over 30 nm. This CML transmitter will be capable of generating a variety of modulation formats including standard NRZ, RZ, and RZ-DPSK. The tunable CML transmitter will fit in a standard 14 pin butterfly package, and consume < 3 W power, and require < 2 Vpp driver voltage. Compared to the conventional lithium niobate transmitter, the CML transmitter will be 6 -10 times smaller, consume 3 times less power, with similar performance. |

| Title: | Generic Adaptive Approaches for Orbit and Attitude Determination on Earth Pointing Spacecraft |
| Abstract: | Many critical space assets include imaging payloads that keep vigilant watch over the Earth's surface. The navigation (NAV) and attitude determination and control (ADCS) approaches traditionally used to control these assets rely on the use of GPS (Global Positioning System) and a variety of ADCS sensors as primary inputs for control. However, GPS and ADCS sensors are at some risk of loss, outage, or degradation. Microcosm, with partner HRP Systems, proposes to develop innovative NAV and ADCS approaches, derived from Plug and Play (PnP) avionics and software development concepts, to provide primary and back-up NAV/ADCS operations for these critical Earth pointing space assets. The team will analyze discrete NAV and ADCS mode changes based on sensor performance and availability, as well as the development of a flexible Kalman Filter that seamlessly transitions as the complement and/or quality of inputs changes. These frameworks allow for a broad array of traditional NAV and ADCS sensors, as well as the integration of "synthetic sensor inputs" which could come from specialized payloads, communication devices, or ground interaction. The team will draw from their involvement in the PnP ADCS/NAV activities of AFRL's Responsive Space Testbed (RST) and PnPSat to develop the proposed capabilities. |

| Title: | Multispectral Synthetic Aperture Satellite Attitude Sensor System |
| Abstract: | To address the Air Force need for backup sensor capability for earth pointing and attitude determination, Physical Optics Corporation (POC) proposes to develop a new Multispectral Synthetic Aperture Satellite Attitude (MUSAA) sensor system that fuses data from multiple infrared spectral bands into a synthetic aperture system for accurate location of beacons and/or geographic features. This system consists of an all-reflective telescope coupled to a 6 in. x 6 in. x 4 in. box containing space-qualified electronics and optics. The MUSAA system will achieve earth pointing accuracy better than 1 arc second by implementing the first satellite-based combination of synthetic aperture, multiple distributed beacons, and multispectral imaging. It will have high reliability as a result of sensor and multispectral redundancy, robustness from proprietary POC reflection control, the capability of rejecting spurious signals within the imaging band, automatic gain control, and correction latency of <1 ms in all modes. In Phase I POC will demonstrate the feasibility of MUSAA by building a theoretical model, fabricating a benchtop prototype, and conducting laboratory testing and evaluation. In Phase II we plan to develop an optimized prototype system with integrated optics, electronics, and software, and will demonstrate real-time earth pointing. |

| Title: | Impact Assessment for Defensive Counterspace (IA4DCS) |
| Abstract: | A key element to supporting Space Situation Awareness (SSA) and Defensive Counterspace (DCS) operations is to develop capabilities that address the characterization and the impact assessment that attacks and environmental effects have on our military space infrastructure. The Space Vehicles directorate of the Air Force Research Lab (AFRL/VS) has funded several programs in recent years studying the application of data fusion theory to automated abnormality and threat detection and characterization. As a member of the AFRL/VS Data Fusion Research Team, Charles River Analytics is currently working on Situation Assessment for Defensive Counterspace (SA4DCS), a suite of relationship and situation assessment algorithms within a large-scale, multi-level Space Awareness and Response System (SARS). In order to estimate and predict the implications of the assessed relationship and situational states generated by SA4DCS, we propose to develop an Impact Assessment System for Defensive Counterspace (IA4DCS). IA4DCS aims to extend current research and development efforts within AFRL/VS's SARS to include Level 3 data fusion impact assessment processing in order to achieve the necessary discrimination and mission impact and appropriate response generation to man-made events, space weather occurrences, and satellite abnormalities. |

| Title: | A Markov Game Theoretic High Level Data Fusion Approach for Defensive Counterspace |
| Abstract: | We propose a highly innovative Markov (stochastic) game theoretic level-3 data fusion approach for defensive counterspace. It is known that Bayesian Network is an insightful approach to determine optimal strategies against adversarial opponent. However, it lacks the essential adversarial decision processes perspective and has the following disadvantages: 1) it needs prior information (or details specific to an unidentified adversary), and 2) assumes only one player. Since game theory is more realistic for addressing the presence of intelligent adversary in decision making, Markov (Stochastic) game model is used to estimate the belief of each possible enemy COA (ECOA), which is proposed here to represent the effect of satellite threats such as space weather and man-made threats. Our multiplayer non-zero sum game theoretic approach is more effective because it takes into account the fact that both the adversary and the neutral players (normal spacecrafts) are intelligent. We integrate the deception concept in our game approach to model the action of purposely rendering partial information to hide the space attackers. With the consideration that an attacker may act like a neutral or white object (normal spacecrafts), we also model the actions of white objects in our non-zero sum Markov game framework. |

| Title: | Satellite Threat and Environmental Effects Assessments for Defensive Counterspace |
| Abstract: | Satellites and other spacecraft are a key asset and critical vulnerability in our communications, surveillance and defense infrastructure. Space Situational Awareness (SSA) and Defensive Counterspace (DCS) efforts are aimed at leveraging the massive amounts of data gathered from ground, air and space based sensors to monitor and ideally protect these assets. While there has been much work on data fusion in this area, the efforts to date have not yielded estimates of impact and cost of a given situation or suggested courses of action (level 3 data fusion). This gap is largely due to an absence of historical data relevant to hostile threat scenarios and other anomalous conditions that require countermeasures to ensure continued satellite functioning. The proposed technology leverages Automatic Red Teaming (ART) agent based simulation techniques to generate realistic data relevant to likely threat scenarios - including estimated impact and course of action evaluations. This simulated data can then be analyzed (akin to lower level data fusion approaches) in order to support automatic detection, categorization, and countermeasure suggestion for future satellite data. |

| Title: | Advanced, Lightweight Structural Materials |
| Abstract: | The extreme operating environment and high performance requirements of space vehicles and structures necessitate designs that simultaneously optimize mass efficiency and reliability. These criteria are in direct opposition since reliability comes with a weight penalty and, conversely, extreme mass efficiency leads to reduced reliability. These conflicting goals, in the unforgiving, expensive operating environment of space, require that designers have access to sophisticated analytical tools to predict the behavior of these structures. This project will further develop an innovative composite structures analysis approach known as Multicontinuum Technology (MCT). MCT is a finite element based multiscale technology that is accurate, extremely efficient, and highly accessible to the structural analyst. Evidence from the Worldwide Failure Exercise suggests that MCT is poised to become one of the premier numerical analysis tools for composite structures For verification, an experimental program consisting of combined thermal and multi-axial loading of composite cylinders will be included. Finally, in the second phase of the program, we intend to illustrate the value of the improved analytical techniques by leveraging MCT and our proprietary variable-kinematic finite element technology (VKFE), to perform for the first time an accurate and efficient progressive failure analysis of advanced grid stiffened composite structural components. |

| Title: | Advanced Architecture, Super Lightweight Structural Composites for Space Applications |
| Abstract: | Future communication satellites require advances in materials and structures to increase vehicle payload ratio. Traditional metal- and composite-based approaches have matured to the point that meaningful improvements in structural efficiency are difficult to achieve. KaZaK proposes to develop and demonstrate a unique composite reinforcement architecture based on novel carbon fiber preforms in combination with matrices optimized specifically for spacecraft applications. Carbon/epoxy composites manufactured by techniques proposed here have already demonstrated surprising improvements in mechanical properties over conventional composites, including a 30% increase in tensile strength, an order of magnitude improvement in fatigue life, increased stiffness and reduction in delamination damage. KaZaK will show that expanding this revolutionary reinforcement architecture from epoxy to include novel high performance matrices tailored for space environments will provide higher temperature capability and lower outgassing. In addition, the proposed technology will enable production of thinner-walled composite parts with mechanical properties equivalent to conventional thickness structures, leading to super lightweight components. In addition to demonstrating improved material properties in Phase I, KaZaK will work with a commercial satellite company to develop a new satellite structure that takes maximum advantage of our improved composite technology, then compare this composite alternative to a current technology aluminum satellite baseline. |

| Title: | Advanced Carbon Nanotubes- based Polymer Matrix Composites for Satellites |
| Abstract: | Significant reductions in structural weight are urgently required in order to create higher payload communication satellites. Reductions are commonly sought through the use of strong, stiff and lightweight composite materials that sometimes possess as an additional advantage good thermal, electrical and radiation protection properties. Carbon nanotubes are promising reinforcements for Polymer Matrix Composites (PMCs), but the problems experienced when attempting to incorporate them at high or even moderate loading into a polymer matrix are not yet resolved to the extent of being able to take full advantage of the great potential of nanotubes. The problem of selecting a polymer and then using it to create a composite with a desired set of properties will be addressed by developing a new technique for incorporating the nanotubes into the polymer matrix, consisting of stacking thin uniform large area nanotube mats in alternation with polymer films and then consolidating them into a laminated composite by applying an appropriate thermobaric treatment. In Phase I, laminate PMCs with high loadings of large area mats of double walled carbon nanotubes (DWNTs) and based on high-performance polymers will be manufactured, and their mechanical, thermal and electric properties evaluated for compliance with communication satellite specifications. |

| Title: | Drill End-Effector for Robotic Drilling in Confined Space Aircraft Inlet Ducts |
| Abstract: | The Air Force needs a Robotic Drilling System (RDS) for drilling and countersinking holes in JSF inlet ducts. We propose a team to develop all elements of a complete RDS: Robot/Robotic Application; Drill End-Effector (DEE); Metrology System; Cutting Tools; and an Automatic Tool Changer. This proposal focuses on the DEE. We propose to develop a Vacuum Nose-Lock/DEE (VNL/DEE). Robots can accurately position drills, but robots lack rigidity required during drilling, so hole quality can be poor. Positive clamp-up forces can be used to increase structural rigidity. However, maximum allowable forces on ducts limit positive clamp-up forces and, therefore, rigidity and hole quality. Our VNL/DEE provides negative clamp-up forces that subtract from drilling forces to produce: small (or even NET-ZERO) forces on ducts; rigid structures; and precise holes. Our VNL/DEE has compact dimensions to access a high percentage of holes in JSF inlet ducts. In Phase I, we will demonstrate our VNL/DEE. In Phase II, we will: implement needed improvements; and fully develop our VNL/DEE and RDS for initial pilot production capability. In Phase III, our team will integrate our RDS for lab and full-scale milestones and production floor cell integration. |

| Title: | Terminally Guided Robots and Robotic Applications in Confined Spaces |
| Abstract: | This proposal focuses on the need to develop a cutting tool for the robotic drilling process. We have enlisted ComauPico as a partner in this venture and all testing shall be carried out in their robotic drilling testing cell by their engineers. This will allow us to get first hand information in robotic drilling that we would not have otherwise been available. In ComauPico's recent testing, it was observed that there can be a point where the thrust exerted by the drill exceeds the force of pressure foot. In talks with ComauPico we have identified this as the root cause that has led to the inaccuracies reported in their testing. Composite Cutter Technology's proposal is to develop a drill bit comprised of state of the art materials while incorporating advanced, patent pending cutting geometry to enhance the initial cutter-to-material engagement, which will reduce the forces on the material and the robotic system. Without the development of a cutter of this type, the thrust forces from the drilling process exceed the levels required for robot stability and consistent hole quality that are required by today's aerospace industry. |

| Title: | Flange edge-location metrology sensor for robotic drilling in the JSF inlet ducts |
| Abstract: | A sensor is proposed that will allow the robotic system to "see" the frame mounting flange through the inlet duct wall. The ability to directly perceive the location of the flange circumvents the stackup of a number of metrology errors, alleviating the problem of holes in violation of edge margin requirements and potentially offering designers with the option of reducing frame mounting flange widths. Northrop Grumman's own study indicates that accurate kinematic modeling is not enough to solve this problem, and they are seeking new metrology approaches. Phase I will demonstrate the feasibility of the sensor by testing it in a manner that closely emulates its use in the real application. The objective will be to prove that the sensor can locate the flange to the necessary accuracy in the presence of representative manufacturing and material tolerances. In addition, Phase I will both define the integration of the sensor function into the robotic drilling metrology process and incorporate the sensor design into the overall robotic system design, including packaging, signals, and electrical and mechanical interfaces. Phase II would undertake integration of the sensor systems into manufacturing robots and demonstrate their use with test articles and subsequently in pilot production. |

| Title: | Terminally Guided Robots and Robotic Applications in Confined Spaces |
| Abstract: | Variation Reduction Solutions, Inc. (VRSI) has created a partnership with Comau Pico to address the Air Force's stated desire to increase the use of robotics in aerospace manufacturing. Standard articulating arm robots are not currently in widespread use due to their inability to hold aerospace manufacturing tolerances. The current industry trend to create perfect robots through the use of correction modeling and software can be expensive while resulting in complex systems with no in-process positional verification. The robot arm that can fit in and reach through the confined space will likely have deflection under gravity and drilling loads. Additionally, many commercial guidance packages can't meet the accuracy requirements or won't fit the confined space application. To address these issues and meet the aggressive Phase 1 timeline and production schedule for the F-35, VRSI proposes a method to utilize off-the-shelf robots and existing metrology industry hardware in an innovative solution that provides the required accuracy, process control, validation, and robustness. Together with our partner Comau Pico, we offer a comprehensive metrology-based system solution for inlet duct robotic drilling with a technology approach that will meet the process requirements and enable the broader use of robots in aerospace manufacturing. |

| Title: | GaAsP Photo-cathode process improvement |
| Abstract: | Intevac has been manufacturing high performance III-V semiconductor photocathode-based electron bombarded sensors for low light level imaging and photon detection for over fifteen years. The focus has been long-range target identification at 1.5 microns, light detection and ranging at 1.06 microns, and VIS-NIR night vision systems. Intevac's wide range of sensors and detector products have been optimized for these applications using high quantum efficiency (QE) gallium arsenide (GaAs) and indium gallium arsenide/indium phosphide (InGaAs/InP) photocathodes. Intevac has invested heavily in transitioning its core photocathode manufacturing processes from single-wafer, metal organic chemical vapor deposition (MOCVD) development tools to state-of-the-art, multi-wafer MOCVD production tools for high volume, low cost manufacturing. Several high priority Navy programs require the use of detectors and sensors with high performance in the blue-green portion of the electromagnetic spectrum. These devices have typically been manufactured using gallium arsenide phosphide (GaAsP) photocathodes in order to achieve optimum QE in the blue-green wave-band. Historically, Intevac's MOCVD development tools have not been able to produce GaAsP photocathodes with stable QE and wafer yield. The purpose of this SBIR is to develop a process to consistently produce high yield, high QE GaAsP photocathodes using Intevac's state-of-the-art MOCVD production tools. |

| Abstract: | To address the Navy need for an innovative process to fabricate gallium arsenide phosphide (GaAsP) photocathodes to improve photosensor performance parameters including wide dynamic range, uniform QE, reduced cost, and high yield, Physical Optics Corporation (POC) proposes to develop a new process for fabricating GaAsP transparent photocathodes directly on glass substrates. The process is based on new, highly efficient fabrication of GaAsP photocathode directly on an n-type silicon layer. Elimination of bonding to the glass substrate and etching of an initial wafer precludes the distortion of photocathode structure and facilitates integrity thus increasing the yield and enhancing quantum efficiency. The process offers better integrity of the photocathode structure, with reduced stress; improved dynamic range, quantum efficiency, and photocathode uniformity; and increased production yield. Photocathode produced by the new process will then be tested in an existing photodevice. In Phase I POC will demonstrate the feasibility of this innovative process and develop a detailed plan for its implementation in the fabrication of existing photodevices. In Phase II POC will conduct a detailed investigation of each production step, implement the innovative process photodevice fabrication, and demonstrate the parameters of the GaAsP photocathode in the device selected. |

| Abstract: | Environmental adaptation is critical to the success of vital ASW missions. Environmental adaptation is particularly important for confident and effective multi-static active ASW in challenging littoral waters characterized by a high degree of uncertainty and variability. Acoustic sources are required to generate the transmission loss or reverberation needed for inversion of bottom properties. Non-explosive sources provide logistical and tactical benefits to the inversion, but they also introduce some computational challenges. Specifically, algorithms are needed for the processing (inversion) and implementation (deployment strategy) of the non-explosive sources for environmental adaptation. The Adaptive Methods team brings a wealth of experience and expertise in the areas of environmental adaptation, geoacoustic inversion, Air ASW operational concepts, and underwater acoustics. Building on prior research in related areas, the team will meet the following objectives in the Phase I research: 1) the specification of processing algorithms for inversion, using a baseline of concurrent inversion based on the Adaptive Simulated Annealing approach; 2) the specification of deployment algorithms, using a baseline of an initial sparse field concept; 3) an evaluation of the algorithms that is data-driven and based on tactical performance metrics; and 4) a comprehensive, integrated plan for deployment of the algorithms to the fleet. |

The solution proposed is based on the experience that Echo Technical has with the development and validation of acoustic propagation algorithms in broad ocean areas and with miniaturized sparker acoustic sources recently developed. Key features of the solution include the use of data simulation from representative scenarios, a critical evaluation of the ability of each algorithm to invert the data and recover the original environmental specification, and a subjective evaluation of the overlapping capabilities of algorithms that may be applied in a layered integrated approach. The fidelity of data sets generated will be enhanced by the detailed specification of physical and functional characteristics of one or more sparker implementations, any of which can be demonstrated to be realizable in near term application, based on previously developed Echo Technical fieldable prototypes. |

| Title: | DEVELOPMENT OF LOW-COST, HIGH-EFFICIENCY, HIGH-DENSITY, DIGITALLY-CONTROLLED DC-DC CONVERTER |
| Abstract: | The unique requirements of the high-voltage capacitive load DC/DC converter for the Navy's non-explosive based acoustic source provide an exciting opportunity for applying innovative design concepts not commonly encountered in commercial power supply product design. The objective of this SBIR proposal is to investigate the technical feasibility of a unique 6000V DC/DC converter design to achieve high power density, high efficiency, and extremely low manufacturing cost at the same time. The proposed converter features a simple yet elegant interleaved parallel/series flyback topology, an innovative control mechanism to enhance the energy delivery efficiency under a wide output voltage range of 0-6000V, and a highly compact magnetics design. The novel control mechanism includes a variable frequency peak current mode digital control strategy and a feedback control loop completely isolated from the high voltage load, Our preliminary first order modeling analysis indicates that these proposed design concepts show a great promise in meeting the Navy's product specifications. A more elaborated research plan in the design, modeling, analysis, optimization, and prototyping of the converter is provided in detail in this proposal. In the Phase I option, one or more prototypes will be built in order to verify and improve the proposed design concepts |

| Title: | COMPACT HIGH-POWER DC-DC CONVERTER FOR NAVY NON-EXPLOSIVE ACOUSTIC SOURCES |
| Abstract: | The evolution of technology, over the past decade, has resulted in the miniaturization of electronic packaging in commercial and military applications; this has pushed the demand for higher power densities in low and high voltage switching power supply designs. Due to increased electric field stress, it is a challenge to design large power densities in high voltage applications. Existing methods to address the high voltage issue, result in the introduction of undesired parasitic reactance, which adversely impacts the efficiency and reliability of the converter power stage. To address the problem, the proposed Phase I research intends to investigate the technical feasibility of using a resonant topology to utilize the unwanted parasitic reactance in the power stage. |

| Abstract: | This proposal is to demonstrate a new DC-DC converter that meets power density, power, life, thermal and cost goals for SEA sparkers. Phase I will include characterizing DC-DC performance in charging a capacitive load of a SEA sparker as well as with a stand-alone SEA sparker system. Test results will be used to design and estimate the cost of a DC-DC converter for use in a SEA sparker, leading to a design of a new SEA sparker and that incorporates the benefits of the more compact converter. In Phase II the new converter design will be built and tested and prototyped for manufacturing, and the new SEA sparker built and tested at sea in a new sparker for SEA. |

In this proposal we investigate innovative mitigation methods that have the potential of suppressing atmospheric noise in LF/VLF communications. Performance objective is to improve routine VLF and LF reception in natural atmospheric noise conditions that will permit greater communications range and to reduce the cost of providing electrical power to the Navy fixed VLF and LF transmitters. Extensive computer simulations will be performed to evaluate the developed methods, and a final recommendation will be provided at the end of Phase I. |

| Title: | User-Centered Communications Manager |
| Abstract: | The User-Centered Communications Manager (UCCM) maintains a queue of proposed transmissions that ensures the communication channel is filled with the most valuable data at any instant. A priority based on inherent value, timeliness, urgency, and novelty is computed for each item, and may be updated before it is selected for transmission. Prioritization (which may delay or drop some transmissions), along with choices between alternative modes and formats for the information, reduce bandwidth needs. Pilots will be able to fine-tune priorities by stating their preferences as policies during mission planning. A Plan Execution Monitor will identify unexpected problems and opportunities and add them as prioritized transmissions in the queue. Prioritization policies are set by a product-line approach, where general models are created by a Navy maintenance organization and fine-tuned by mission planning in the Wing. No new work flow or training is required for pilots to use the system during a mission. This work will be based on significant ontology and code resources Teknowledge has already created. Both UCCM and Plan Execution Monitor will be designed to be broadly applicable for other Navy communications situations. |

| Title: | Intelligent Information-Gathering Agents |
| Abstract: | Toyon Research Corporation proposes to develop a novel algorithm for dynamically prioritizing information available to members of a distributed intelligence architecture. This algorithm will allow a network agent to determine what information is of most value to client agents onboard aircraft based on tactical objectives and the current battlefield situation. Our approach is to use Dynamic Bayesian Networks (DBNs) - a leading technique in the field of artificial intelligence - as a data structure to model the current information content of each agent in the network and determine the appropriate level of detail to transmit. As new data is received by an agent in the network, the resulting improvement in mission-specific knowledge is quantified through measures from information theory. If the change is significant, the network agent transmits the information to appropriate agents in the network. In Phase I, we will develop appropriate DBNs for representative naval missions, develop a software prototype, and demonstrate the feasibility of the approach and algorithms. In Phase II, we will refine the scheme and develop a more sophisticated prototype that would allow us to demonstrate and evaluate the scheme. |

| Title: | Automating Ship Assembly Planning and Simulation |
| Abstract: | First Marine International, in their latest benchmarking study of the global shipbuilding industry, identified production preparation as one of the key items preventing U.S. shipbuilders from reaching world quality status. These problems are partially caused by a lack of standardized tools to support and automate production planning operations. Simulation tools offer a powerful method to analyze production capabilities, resources, and provide feedback to planners on optimizing assembly planning and sequencing. However, use of simulations is limited due to the long set-up times and steep learning curve. The team will investigate the possibility of automating the creation of a simulation model from an existing assemply planning program. Standardized resource models which describe shipyard facilities, along with the assembly structures definitions extracted from product model data will be used as inputs into a discrete event simulator. The resource model will be rules driven, modular and customizable, enabling work packages to be created at one site and rapidly modified to reflect the work environment at another site. The platforms used will be open and interoperable in order to encourage industry collaboration. |

| Title: | Design and Engineering Integration During the Weld Lifecycle |
| Abstract: | Welding is one of the most important aspects of shipbuilding. Welds are one of the largest labor and material components in ship delivery. Also, the effect of even a single weld failure can be catastrophic to the ship's performance and to crew safety. In spite of its key role, welding in the shipbuilding industry suffers from many problems that plague the welding industry at large as well as challenges unique to shipbuilding. These challenges have created a situation where welding is a high-cost process that lacks useful tools and methods to increase efficiency and lower costs. The proposed solution combines recent research from the welding industry with technology and innovations from Knowledge Systems Solutions to create a rule-based suite of software that supports an interoperable weld lifecycle. The proposed solution will 1. Document a weld lifecycle commonly used in shipbuilding. 2. Implement an open system architecture and neutral data modeling standards for interoperability. 3. Create a suite of rule-based software tools to capture, manage, and reuse best practices and lessons learned. 4. Provide a business model that allows companies to incrementally implement the solution with a quick return on investment. |

| Title: | Conductor and Element Design: Minimizing Recovery time in Superconducting Fault Current Limiters |
| Abstract: | For Navy ship electrical systems there is a need for a new electrical component, a fault current limiter, that can provide several "automatic" functions. Presently, fault detection takes about 80 microseconds with the right instrumentation. Several kinds of faults have short duration, but the difficulty is riding through these faults, especially with electronic switches, which have distinct voltages and current levels, above which the components fail or turn off. If the fault is not of a short duration, then it would be good to limit the fault current long enough to automatically implement fault management to isolate the fault, perform diagnosis, and allow for power re-routing if possible to maintain a combat state. It would be preferable to do this in less than 100 milliseconds, if possible. If ride-through or re-routing is not possible it would be useful to provide current limiting until a mechanical breaker has time to respond. In addition, if the current is limited, smaller current breakers can be used and distributed around the ship to give more opportunities for a re-routing of the current. A superconducting fault current limiter enables all of these functions "automatically". The objective of this SBIR Phase I is to develop a system concept design for a YBCO coated conductor based superconducting fault current limiter for Navy ship applications. |

| Title: | Investigate and Develop an Analytical Approach to Automatically Mitigate Electrical Faults Caused by Battle Damage |
| Abstract: | Electrical faults in the shipboard power system can result in the loss of power to critical loads of the system because today's electrical systems protection devices cannot clear faults in less than a cycle or two. The result is that very high current flow in the system. In this Phase I SBIR, we propose to develop an initial concept to limit the fault current magnitude by interrupting the current in less than 100 æs from onset of fault. To accomplish this we propose to use a fast opening mechanical contactor with solid-state switches in parallel. The fast opening mechanical contactor is actuated by magnetic forces and can interrupt fault current in 100 æs. This concept was proven at the 440 V system level, and we are proposing to extend it to the medium voltage level. The successful development of this technology will provide revolutionary new capability in system protection and load survivability. |

| Title: | Tailorable Packaging System for Optimized Protection in LCS Mission Modules |
| Abstract: | KaZaK Composites proposes a modular packaging system to protect energetic materials carried inside LCS mission modules. A readily tailorable set of standardized protective panels, in combination with an integrated system for securing items inside mission modules, will allow minimum cost/weight protective solutions to be rapidly designed and implemented. A layered approach will allow individual dangerous packages to be optimally protected against detonation from external blast effects, projectiles, fragmentation, spallation, fire and RF energy. In addition, internal modular packaging will prevent adjacent energetics from sympathetic detonation should one item in the mission module ignite or detonate. This system will allow LCS ISO mission modules to be handled as if their contents were inert. KaZaK is uniquely qualified to address this topic, having extensive experience in energy-absorbing materials, protection against blast, thermal effects, ballistic penetration, modular munitions packaging, containerization, design of lightweight military ISO containers, packaging systems for military shipment, and design for low-cost automated composite production. To minimize risk and production cost, designs will be based on proprietary technologies already proven in similar applications. Proposed hardware will be produced by pultrusion, a KaZaK specialty and the least expensive way to make constant section composite parts. |

| Title: | Self-Monitoring Energetic Materials Storage Module |
| Abstract: | Energetic materials require extensive mitigation with respect to storage and handling procedures. This typically results in large cost and weight penalties when applied to shipping or storage containers. Any container or containment system also must meet stringent fire retardant properties if it is stored on a ship, in addition to meeting reduced smoke and toxic emission requirements for below deck applications. Luna Innovations will propose a module material concept which combines blast mitigating coatings, fire retardant composites, and Luna's proprietary active temperature sensing. This material system will also mitigate the RF activation and shock risk factors associated with energetic material transportation. The material concept will be designed for use in the pultrusion process which will result in a module with low production costs. |

| Title: | High Energy Material Containment |
| Abstract: | The Navy desires a containment system that provides isolation of energetic materials, so that they can be stored and handled as an inert payload with minimal risk of activation or unconstrained release of energy. Current containers are heavy, costly, provide inadequate ballistic shielding, and do not provide the desired logistical handling characteristics. Texas Research Institute Austin, Inc. (TRI/Austin) and subcontractor Container Research Corporation (CRC) will develop material and structural concepts for a lightweight, low-cost, high-energy material containment system that is also payload independent, scalable, modular, and conforms to industry standards. Several innovative methods of providing heat-, ballistic- and blast-shielding capability will be explored, including laminated composites, low-cost yet high-performance reinforcements, and unique coatings that enhance blast- and fire-resistance. Innovative joint designs will be incorporated to reduce the likelihood of blast-induced damage. TRI/Austin will evaluate candidate container design concepts using analytical and empirical methods. Representative wall panels will be fabricated and tested to demonstrate the structural, ballistic, and fire performance of selected approaches. The resulting metrics will allow TRI/Austin to recommend a detailed design concept for further development. Finally, an economic analysis will be performed to provide a cost comparison with existing designs. |

| Abstract: | To address the U.S. Navy need to reduce or eliminate the accumulation of water and ice on the surface of the bridge windows of surface ships, Luminit, LLC proposes to develop a unique SuperHydrophobic/hydrophilic Advanced Window (SHAW) system based on our technology for sol-gel replication technology of 3D nanoscale surface relief moth-eye structures. The nanoparticle-doped moth-eye structure replicated in sol-gel will result in excellent glare reduction and scratch resistance, while the nanostructured surface relief pattern will make the window self-cleaning, anti-fogging, and non-icing. The SHAW system will be manufactured by laminating: glass substrates coated with a superhydrophobic (anti-wetting); a superhydrophilic (anti-fogging) coating; and an index matched indium tin oxide coating as an EMI shield. The standard window lamination process will ensure that SHAW meets or exceeds the requirements for optical qualities, EMI, shock, vibration, and applied static pressure. In Phase I Luminit will develop and demonstrate the feasibility of the SHAW system by coating superhydrophobic/hydrophilic material on glass samples and laminating them together. The laminated samples will be tested to relevant MIL-SPECs for self-cleaning, anti-fogging, scratch resistance, and environmental durability. In Phase II Luminit will optimize the scale-up fabrication process and perform a cost benefit analysis. |

| Abstract: | Maintaining a high level of visibility in surface ships is very difficult under very inclement environmental conditions. Mechanical systems such as wipers and spinning windows are known to malfunction, are costly to maintain, and also impair vision during clear weather. New systems are required to improve visibility during heavy rain, snow, and ice. The requirements of this system are that they are self-cleaning, anti-fogging, non-icing, scratch resistant, glare dampening, and will provide a low Radar Cross Section (RCS). Luna proposes the combination of our developed coatings with proven electro-thermal deicing technology to produce a bridge window system that will meet all of these requirements. This window system will be inexpensive to produce and operate, and will improve visibility for Aegis class and other Navy surface ships. |

| Abstract: | The objective of the proposed Navy SBIR program is to demonstrate economical, high performance, multifunctional bridge window coatings that offer high levels of electrical conductivity, high optical transmission, high levels of hydrophilicity (for anti-fogging and anti-reflection), and improved abrasion resistance for current Navy and DoD ship platforms. The immediate goal is to demonstrate improvements over other currently available bridge window designs, specifically targeting lower cost, EMI shielding, abrasion resistance, anti-fogging and de-icing functionality, high impact and shock resistance, high optical transmission, and with minimal optical anomalies for use with night vision goggles. NanoSonic has demonstrated that extremely low percentages of its novel nanomaterials are required to elicit high levels of conductance and tailored electromagnetic response on glass, polycarbonate, and acrylic substrates. Additionally, NanoSonic has done significant related work with similarly fabricated, extremely hydrophilic coatings (anti-fog, self-cleaning) that have inherent anti-reflective properties and are readily integrated with ship bridge windows. NanoSonic will work with systems integrators to address specific requirements for DoD and Navy applications. |

| Title: | Development of a Power System Management Tool to Support Automated Damage Control for Shipboard Power Systems |
| Abstract: | As modern naval vessels become more electrically integrated, managing the total energy resources becomes critical. Currently multiple systems exist to "manage" the system as opposed to a single unified power system management tool. Williams-Pyro, Inc. is proposing a software-based approach that is capable of representing the shipboard power system's dynamic performance, steady-state performance, and system reconfiguration routines in one comprehensive tool. The basic objective of our power management scheme is to identify, isolate, and reconfigure all fault conditions; initiate load adjustments in response to specific contingency triggers; and maintain the stability of the power system. We will achieve these goals by developing algorithms based on proven techniques such as rule-based engines, dynamic integer programming, expert systems, and discrete events. The entire system can act as a stand alone software module or integrated with the ship's command and control. This software-based approach can be extended to an embedded platform and reside in Williams-Pyro's AccuTagT Programmable Automation Controller for localized monitoring and control. Having a tool capable of describing the dynamics of the system during reconfiguration is a powerful capability that can transition in many markets, such as the terrestrial power system industry and the automotive industry for the development of modern vehicles. |

| Title: | Stability Improvements of Radar Transmitters |
| Abstract: | he overall objective of this proposal is to develop an approach to improve transmitter stability in order to improve radar clutter suppression performance. One approach is to develop an algorithm to effectively 'equalize' out the instability characteristics of the transmitter. This requires sampling of each transmitted pulse, and real-time development of an equalizer filter to be applied to each pulse. A viable solution has been proposed in work performed by NRL. The specific equalizer design approach taken in this work is a frequency domain approach which uses the transmitter samples to generate filter coefficients that yield the ideal matched filter response when the returns are applied. While it is effective in removing the effects of transmitter instability, it assumes a high SNR on the transmitter sample to achieve the best performance. BCI proposes the use of a MMSE equalizer to achieve a more optimal set of coefficients that allow for the removal of the effects of transmitter instability at various SNRs. |

| Title: | Stability Improvements of Radar Transmitters |
| Abstract: | The U.S. Navy requires highly modern and sophisticated radar system to accomplish missions in littoral water region where near shore terrain and weather in extreme sea-state conditions present challenging clutter environment for moving target indicator (MTI) operations. An important source of this difficulty is caused by the waveform distortions on the radar transmitters. An efficient and effective method to correct the distortions caused by the transmitter is to provide transmitter waveform compensation on the received signal. In this proposal, we will develop a two-step adaptive waveform compensation algorithm based on the adaptive digital signal processing techniques. The developed technique will reduce the inter-pulse and intra-pulse waveform distortions caused by the transmitter power amplifiers and waveguide switching hybrids. The objective of the proposed approach is to maximize the effectiveness of the transmitter waveform compensation for the observable error sources (e.g., CFA, TWT etc.) while reducing received waveform distortions generated by the radar transmitter systems. The developed algorithm is stable, reliable and feasible for real-time implementation. |
