Title:Development of enhanced active damping system for the Marine Corps Expeditionary Fighting Vehicle (EFV)
Abstract:A road wheel suspension incorporating a semi-active damper and fast load leveling spring system will be developed for the Expeditionary Fighting Vehicle (EFV). The system will be designed as a replacement for the currently fielded semi-active suspension system in the same foot print, either in early production units or as a retrofit package for incorporation later in the development cycle. A suspended seat will also be evaluated to mitigate shock and vibration transmitted into the EFV crew during both land and sea operations. In Phase I, a conceptual design of all the major components for the roadwheel suspension as well as the architecture for both control hardware and software will be developed. Dynamic modeling will be used to predict system benefits and provide requirements to the design process. The improved suspension will target equivalent functionality with greatly improved shock, vibration mitigation and improved dynamic stability. The Phase I Option will be focused on generating a detailed layout of the roadwheel suspension based on the component specifications and packaging constraints identified in Phase I. This will provide the basis for the detailed design and fabrication of a prototype system capable of withstanding extended proof of concept testing in Phase II.

Title:Technology for Advanced Ship Designs: SEA-Pro
Abstract:Electrical system design requires several studies and calculations be conducted to verify proper operation of the system and specification of equipment. This includes fault current calculations, load analysis, motor starting analysis, harmonic analysis, generator response studies, electro-magnetic interference, breaker coordination, etc. Software applications are available for conducting many of these studies. Commercially available packages, however, were originally designed for land-based facilities, which were not intended to address the unique requirements of shipboard installation. The shipboard installation requirements do, in fact, significantly affect the original system design parameters. Because shipboard requirements are currently not integrated into the original system modeling and analysis, much of this analysis requires later modification. Also, because the data developed during modeling and analysis is not readily transferable to shipyard production requirements, much of the data input requires duplication, which increases production costs and introduces errors in equipment procurement and installation. SEA-Pro will reduce design and production costs by providing an integrated marine electrical engineering analysis and production capability to the US Naval and commercial shipbuilding industry. The tool will also lend itself well to lean design/manufacturing assessments by providing a marine specific model of the vessels electrical production requirements.

Title:Pultrusion-Based Fabrication of Revolutionary Phenolic Foam Replacement for Balsa in Navy Ship Structures
Abstract:KaZaK Composites proposes development of a revolutionary fire resistant structural core material that will ultimately become a replacement for balsa in Navy sandwich panel construction. Balsa is currently the baseline material for structures like the DD(X) composite deckhouse. However, this baseline material has a number of shortcomings including inconsistent material properties (because it is a natural material), moisture absorption and associated degradation, and absorption of a considerable weight of resin during the VARTM manufacturing process. KaZaK's phenolic-based alternative will have far more consistent mechanical properties, and has been formulated to improve fire and impact resistance. KaZaK will also demonstrate an innovative manufacturing process for making sandwich panels of the type used by DD(X) that, once perfected, will greatly reduce the cost and simultaneously improve the performance of composite sandwich marine structures. In Phase I KaZaK will fabricate a large number of core material formulation alternatives and subject them to mechanical and fire tests to evaluate their relative performance. In addition sandwich panels will be constructed using a unique processing approach, tested in bending and impact, and results compared to balsa. Results will be reviewed by NGSS and other shipbuilders as part of KaZaK's regular meetings with our existing customer base.

Title:Technology for Advanced Ship Designs
Abstract:The cost effective intergration of a fire protection system into a multifunctional composite structure is a goal of the shipbuilding industry. The current practice of fire protection blankets over composites for fire protection is costly, difficult to maintain, difficult to install and ineffective for several threat scenerios. Structural Composites proposes to refine a new innovative Spray Bag composite fabrication process to provide fire protection. This innovative Spray Bag material facilitates the composites' infusion fabrication process and remains as part of the structure as the fire protection system. The major technical challange which list project will address is the ability to spray an elastomeric coating that has inherent fire protection directly onto dry fiber reinforcements, frames and ports in such a manner that will form a vacuum-tight bag directly on the fabrication mold.

Title:Material Investigation for Navy Composite Sandwich Panel Solutions
Abstract:There are various performance drivers that affect composite sandwich panel construction for Navy applications. Among these drivers are fire performance, structural properties, impact resistance, durability and cost. The sandwich panel material system includes the core material, the facings, the resin system and secondary coatings or facings; all of which can be varied to obtain specific sandwich panel properties. Currently, there is no single material system that provides excellent performance in all of the above areas; in fact many performance drivers run counter to each other when attempting to optimize materials for a given application. This makes material selection problematic and can lead to a circular approval pattern where one group's design drivers can steer the material selection such that it negatively affects performance in other areas or overall panel cost. This program will evaluate several material systems for use onboard Navy ships, these material systems include PVC foam core and balsa cores as well as various forms of the TYCORr material. An array of constructions that have varying degrees of fire performance, weight and cost will be manufactured and tested with the goal of identifying multiple material combinations that are both cost and weight effective, and offer fire protection that is tailorable to the fire threat for the application.

Title:Composite Isogrid Structure
Abstract:This program creates the design of alight weight, composite, load bearing superstructure for surface ships. The program is supported by Bath Iron Works (BIW) as a Navy Ship contractor. BIW will supply details of structural loading and impact requirements. WCT will design an isogrid reinforced panel structure to accept the loading conditions. Mounting requirements for components are examined and the isogrid system geometry is developed and modeled. Mounting inserts are evaluated for pullout loads and environmental conditions. Pro Engineer and Laminate Design modeling techniques are used to confirm the design. Test data from an existing DOD contract will be used to support mounting design. Panels are closed out with composite skins, one face by co-curing, the other by bonding. Carbon foam will be considered as a fill medium within the isogrid core. This will enhance the bond strength to the closeout skin and provide enhanced strength to the panel. The option program will cover design, fabrication and test of a prototype composite panel. In addition to structural testing, the component attachment system will be tested. Test results are evaluated and an optimum panel design and mounting system are created, leading into a Phase II program.

Title:Simplified Hybrid Stanchions and Lightweight Composite Concrete for CLF Ships
Abstract:KaZaK Composites proposes to develop and implement improvements to current CLF dunnage systems by designing and prototyping a cost effective adjustable stanchion and lightweight concrete. Key requirements for a redesigned dunnage system include elimination of wood dunnage, supporting structural loads, significant reduction in total ownership costs, easily repaired system components, light weight, ease of use and high toughness. Adjustable stanchions will be designed to meet and/or exceed existing load requirements, reduce stanchion weight, withstand environmental conditions (hot, cold, wet), take rough handling and meet fire performance specifications. Lightweight concrete will be formulated for use between diagonal and athwart ship steel rail CLF dunnage systems. Proposed dunnage systems must not impact restraint systems/operations or require costly ship modifications. By engaging CLF ship dunnage systems, KCI and the Navy are insured that developing designs will be compatible, effective and where applicable interchangeable. In Phase I KCI will perform extensive design trade studies, including finite element analysis of critical load conditions, followed by fabrication and testing of key sections of dunnage hardware to validate performance predictions. Composite parts will be tailored for fabrication via the pultrusion process, the least costly manufacturing technology for constant cross section shapes.

Title:Pultruded Composite Structures for Cargo Stowage Systems (MSC P1T11-429)
Abstract:Conventional cargo stowage systems (CSS) aboard Navy ships employ a steel rail diagonal dunnage system that is heavy and requires extensive use of wood block fillers between the stanchions and cargo to properly secure and restrain the cargo. In order to reduce shipboard weight and maintenance requirements, new lightweight material solutions and more efficient CSS structural designs are desired. The proposed research addresses the development and demonstration of new lightweight, damage tolerant, pultruded fiber-reinforced polyurethane composite structures for Navy ship cargo stowage systems. More efficient, lightweight composite structural design concepts and new fire-resistant polyurethane resin formulations will be applied to meet the multifunctional performance requirements of toughness, strength, stiffness and low flame, smoke and toxity. In order to ensure success and provide a path for shipboard integration and Phase II/Phase III commercialization, the proposed research will be carried out by an Integrated Product Team (IPT) consisting of composite material and structural designers and pultrusion processing experts.

Title:Advanced Structural Development for Cargo Stowage Systems
Abstract:U.S. Navy Combat Logistics Force (CLF) ships require cargo stowage systems to secure palletized and non-containerized cargo in the ship's holds. The current steel rail diagonal dunnage cargo stowage system is heavy and requires extensive use of filler material such as wood blocks to fill space between portable stanchions and the cargo. Weight and maintenance savings could also be realized by eliminating the concrete deck filler material used between the diagonal steel rails in order to level the surface for travel of fork lift trucks. This project proposes to develop a cost effective, lightweight, corrosion and fire resistant, durable, composite cargo stowage (CCS) system, that will meet or exceed the structural and environmental exposure design requirements for U.S. Navy CLF ships. The CCS system will consist of composite stanchions, adjustable locking blocks, overhead and deck rails, and deck tiles. The CCS system components will be constructed from composite materials that will meet all U.S. Navy CLF shipboard requirements including structural, fire, smoke and toxicity, and all environmental and chemical exposures. The proposed CCS system will allow for flexible stowage configurations that can be rapidly configured by minimal ships personnel and will be forklift compatible.

Title:Comprehensive Spectrum Management for Wireless Networks
Abstract:Wireless local area networks (WLANs) have become standard technology for government, commercial business, and DoD networks. With this widespread proliferation of RF technology has come a myriad of problems such as how to architect the WLAN for optimum performance, how to easily set-up and configure the WLAN and how to secure the WLAN to protect it from hackers. Solutions for such problems are available and still evolving. However, a newly recognized and just as insidious problem has gotten a lot of attention recently; that is the problem of Spectrum Management. Develop advanced hardware and software technologies for analysis and management of the RF component of shipboard wireless networks. In this SBIR Phase I we plan to demonstrate the feasibility of spectrum management for a wireless network system that utilizes the common unlicensed frequency bands and has the ability to shift to other desired frequency bands. The solution developed will address improvement of throughput through avoidance of interference as well as the ability to avoid the usage of specified frequencies when required by policy. We will accomplish this through the use of extensions to an existing WLAN Management System coupled with adding special purpose spectral analysis ICs to wireless Access Points. Comprehensive spectrum management will include provisions for spectral analysis and characterization as well as RF emitter location techniques. Advanced power management coupled with the use of directional and smart antenna technology is another key aspect of this project. The primary focus will be development of system suitable for handling the complex shipboard RF environment. The system will be capable of being used for Naval and military applications, including requirements for ruggedization, electromagnetic compatibility, information assurance and open architecture. The developed solutions will also have applicability for typical shore-based installations as well.

Title:Comprehensive Spectrum Management for Wireless Networks
Abstract:To mitigate the parasitic characteristics of radio channel, an intelligent RF control plane is desired. Spectrum Management for shipboard wireless modems, consideration for on shore equipment support, emphasis on exiting Wireless LAN protocols (802.11) with consideration for ultra wideband and even IR WLANs, are all required for maximizing radio functionality without having to maximize radio expertise. These requirements dramatically reduce the cost and complexity associated with building a business critical wireless network. A savvy spectrum management system is proposed for frequency coordination of shipboard wireless modems. This system utilizes sophisticated self-organizing interference, emission measurement, and prediction subsystems to determine the best suitable frequency band of operation. The proposed system also employs highly frequency agile front-ends for all its nodes to allow operations in the specified bands. The system will optimize throughput, power, and interference for a wireless networks, taking into account regulatory mandates.

Title:Cognitive Radio Utilization and Integration of Spectrum Emission
Abstract:To address the U.S. Navy need for a wireless network spectrum management system for the common unlicensed frequency bands and that can shift to other frequency bands, Physical Optics Corporation (POC) proposes to develop a new Cognitive Radio Utilization and Integration of Spectrum Emission (CRUISE) system based on software defined radio transceivers and novel cognitive radio techniques. In particular POC will extend the present media access control elements of the 802.11 protocols to address issues arising from hidden and exposed nodes, particularly within directional systems. POC will develop a system for flexible frequency and modulation control. This will reduce bandwidth saturation, automatically reroute network traffic around physical obstacles, ensure data packet fidelity, adjust transmission power to eliminate interference with neighboring transceivers, and extend the range of 802.11 wireless networks by using each network node as a repeater to relay messages to remote nodes. In Phase I POC will demonstrate the feasibility of CRUISE network technology by building a technology demonstration unit to validate all key fundamental principles. In Phase II POC will develop several advanced CRUISE prototypes, which will prove all aspects of its advanced, adaptable, and revolutionary network architecture.

Title:Sensor Synchronization Technologies
Abstract:Shipboard condition monitoring, condition-based maintenance, measurement, and control systems involve the exchange of information among one or more controllers and numerous sensors and actuators. Correct operation of these systems requires that the temporal relationships of the sensor readings, actuator settings, and controller computations be synchronized. Navy desires to achieve the time synchronization of events on all sensors especially the smart/digital sensors utilizing standards and open architectures as much as possible. Under Phase I of this SBIR, 3eTI's Team will perform Tradeoff Analysis for time synchronization technologies. Based on our initial study, we will implement the open standard IEEE 1588 for Precision Clock Synchronization Protocol for Networked Measurement and Control System in the following steps: (i) Developing the IEEE 1588 software and implement it on the 3eTI NCAP platform. (ii) Prototyping the IEEE 1588 time synchronization with IEEE P1451.3 and P1451.5 smart sensors using NCAP as the core platform integrating the smart sensor networks. (iii) Based on performance data, further software and hardware based optimization will be proposed. 3eTI's vision is to develop a unified solution that provides time synchronization support to heterogeneous smart sensor network simultaneously. A report will be provided that details the concept, suggested metrics and estimated life-cycle costs

Title:Sensor Time Stamping for Mixed IEEE 1451 Network Protocols
Abstract:Many applications require that the precise time at which a sensor reading is taken be known. However, time correlation of data obtained from sensors which are distributed over a network or several networks are subject to errors or misinterpretation because different time stamp formats are used, the clocks used for the timestamp may be inaccurate and there may be uncompensated delays in the network data transmission. We propose to provide a precise time stamp which would be built into, or easily added to, all networks which use the IEEE 1451 smart transducer format. It would have time resolutions ranging from microseconds to seconds and not necessarily rely on the Internet or Ethernet network for time synchronization. NIST-based radio time clocks and features of the IEEE 1588 synchronization standard will be used to implement the reliable timing. The Phase I prototype will consist of an Internet type NCAP and two IEEE 1451.2 (RS232) TIMs with an actuator and sensors.

Title:Sensor Synchronization Technologies
Abstract:Williams-Pyro, Inc. proposes to develop a Synchronous Smart Sensor Network (S3Net) system with standardized time-synchronization protocols capable of handling inputs from a multitude of sensors onboard ships. Terrorist threats and other examples of asymmetric warfare are replacing traditional nation-to-nation threats. This new form of military threat requires an integrated information architecture that facilitates a timely distribution of sensor events to a diverse set of shipboard, first responder, local, and national recipients, which will result in improved health monitoring of system components or damage control critical to the survival of a warship and the safety of the crew. S3Net will process and collect data from existing mature sensors using time synchronization protocols based on IEEE 1451 standards and open architecture, wherein each smart sensor determines the sample timing based on the trigger or time obtained from the synchronization clock. The association of the data values and their time stamps will be performed at each sensor.

Title:Power generation for weight and space limited USV systems
Abstract:Synchrotek Inc. proposes to design, during phase I, a 40 kW high frequency generator set for application in Unmanned Surface Vehicle (USV) platforms as a power source to support command and control equipment/modules. The design is based on Synchrotek's Variable Speed Constant Frequency (VSCF) technology. It uses a lightweight twin-cylinder rotary engine as prime mover. The generator is a lightweight permanent magnet generator, which produces variable voltage, variable frequency output when connected to the variable speed engine. An electronic power converter converts the generator output to precise power for AC load at constant voltage and constant frequency, or for DC load to precise DC voltage. The entire system is optimized for the lightest possible weight, expected to be less than 650 lbs. Additional benefits of the VSCF system are improved efficiency of the generator and the entire system over a range of load. This is achieved by controlling the speed of the engine for varying load conditions by an electronic speed controller that senses the load and adjusts the speed. Synchrotek has developed several gen-sets for the Army CECOM, as R & D Effort. Among them are the 3 kW and 5 kW generator/Inverter systems. Synchrotek has developed in-line generator for the Army for a constant speed application that produced 10 kW output at 120/208 V, 3ph, 60 Hz at engine speed of 1200 rpm. The generator is designed for speed range of 800 to 3400 rpm. Three prototype units have been incorporated into HMMWV system for field tests. The proposed high frequency generator will be designed with similar physical parameters, but for variable speed application. The phase I work effort will consist of a comprehensive assessment of mechanical, electrical and thermal trade off for an optimum configuration of a 40 kW generator coupled to a rotary engine The effort will address the electrical, mechanical and thermal considerations of the generator. The phase 1 effort will also evaluate its performance with the Power Electronics package to ensure 40 kW power at precise voltage and frequency and to generate drawings for fabrication of the generators during phaseII.

Title:Lightweight Power Generation for RHIB Platforms
Abstract:Military USV platforms require an increasing amount of electric power to support electronic systems developed for command and control and other loads. Combined with the fact that existing generator sets that provide the 40 kW of required power are too large and heavy for these boats, alternative solutions need to be found. UQM has developed small, lightweight generator solutions for hybrid electric vehicles used within ground vehicles, and can take this technology into RHIB platforms. Several small diesel engines exist as good candidates to become the prime mover of a UQM permanent magnet generator. The conditioned DC power is then fed to one or more AC power inverters for the creation of 60 and 400 Hz power. The feasibility of combining existing and/or modified components will become the focus of the Phase I effort, with the fundamental approach to minimize component development. UQM believes that the building blocks to create a lightweight (less than 400 lbs) generator system exist, and that good systems engineering will become the challenge. Issues of focus include component maturity, component interactions/compatibility, marine environment suitability, and systems-level tradeoffs.

Title:Multi-function Connectors for Shipboard Equipment
Abstract:The United States Navy is developing a multi-mission surface combatant called the Littoral Combat Ship (LCS). The present design supports anti-submarine warfare (ASW), mine warfare (MIW), and surface warfare (SUW) mission packages. It also provides underwater vehicle, aerial vehicle, and weapon zones for attaching mission modules. LCS's objective is to support a complete mission change-including an operational test (OPTEST)-within 24 hours. We propose a Pod ConnectorT for rapidly and securely attaching mission modules to a ship's deck. The Pod ConnectorT is self-stowing, watertight, and dirt-free. When the Pod ConnectorT is not in use, it stores upside-down and creates a watertight seal. Unlike protruding fasteners, which are damaged by loading apparatus (e.g. grabs and bulldozers), and recessed fasteners, which fill with dirt and water, the Pod ConnectorT stores flush with the deck's surface. As a result, there is no need for time consuming removal and replacement of the Pod ConnectorT between missions. In addition, the watertight seal prevents thread corrosion and water freezing on contacts, thereby ensuring reliable attachment. Pod ConnectorT variants include one for supplying power and data and another for transferring fluid and gas. The Pod ConnectorT accelerates mission module installation and reduces logistical overhead by rarely requiring replacement. Working with our partner, Lockheed Martin, we have devised an optimal layout for Pod ConnectorT arrays in each LCS zone. This configuration is designed to maximize the effectiveness of existing and future sensor, vehicle, and weapon modules including the Spartan Unmanned Surface Vehicle (USV), Long-term Mine Reconnaissance System (LMRS) Unmanned Underwater Vehicles (UUV), and Phalanx Close-In Weapon System (CIWS).

Title:Selectable Error-Free Analog and Digital Operations Grid Connector
Abstract:Most deck-mounted hardware is permanently attached to the ship's structure, so ships cannot be easily reconfigured to fill gaps in a conventional naval force structure. This means that ships cannot be leveraged when naval forces are scarce in a certain location, or for simultaneous conflicts in widely separated theaters. A multifunctional, rugged, easy-to-use plug-and-play connector will directly address this problem. To meet this U.S. Navy need, Physical Optics Corporation (POC) proposes to develop a new Selectable Error-free Analog and Digital Operations Grid (SEADOG) connector. The SEADOG connector features: (1) a novel 360 degree blind connection, ensuring that hardware can be attached quickly and easily to a ship's structure in any weather or sea state; (2) rapid self-correcting connections for both power and data, ensuring seamless multimedia communication, uninterrupted video throughput, reliable sensor data, and real-time targeting information even within crowded shipboard digital domains; and (3) a self-actuating environmental seal protecting sensitive mechanical and electrical components from the harsh marine environment. In Phase I POC will develop, fabricate, and test a SEADOG connector model to demonstrate feasibility of the concept. In Phase II an optimized and rugged engineering prototype will be built that will be tested under laboratory test conditions.

Title:Algorithms for Rapid and Accurate Depth Localization of Targets for Mine Avoidance
Abstract:The US Navy's new DD(X) destroyer currently under design features amongst its extensive sensor suite an innovative dual (high frequency and mid-frequency) frequency, active bow sonar. One of the primary missions of the high frequency (HF) component of the bow-sonar will be in-stride mine avoidance. Advanced signal processing algorithms, developed for predecessor sonars aboard modern US submarines, allow high-resolution localization (range, depth and relative azimuth) of mine-like objects. However, the performance of these algorithms is degraded under multipath conditions typical of shallow water (<200m) environments. Here we propose to investigate, develop, demonstrate and implement modifications to the existing signal processing sequence to improve the sonar's mine-hunting capabilities in refractive, multipath environments. These modifications will be implemented in a robust, post-monopulse correlated-field-processing algorithm. The proposed algorithm will endeavor to simultaneously estimate both target location and relevant environmental parameters by comparing the beam-time structure of detections on both the real and imaginary parts of the complex monopulse output to efficiently computed, model estimations of the same. Multi-ping trends in beam-time space of the measured and modeled multipath echo differences will facilitate efficient corrections to the assumed sound speed structure and bathymetry via low order empirical and analytical parametric perturbations

Title:Algorithms for Rapid and Accurate Depth Localization of Targets for Mine Avoidance
Abstract:This work proposes to develop an efficient algorithm for rapid and accurate depth localization of mine-like targets in shallow water environments where both direct and multi-path wave propagation exists. The proposed algorithm is an extension of an existing table look-up approach for direct path refraction correction, which has been implemented in real time software at the Atlantic Undersea Test and Evaluation Center (AUTEC) for improved depth localization of targets on range. In this approach, the major computational effort associated with the time-consuming, trial-and-error ray tracing to determine the actual refracted path for each eigen ray (either direct or multi-path) between the emitted pulse from the ship's sonar and the target's reflected position, is conducted prior to implementing the real-time localization based on sound velocity and travel time. The result of this a priori computation is termed the effective sound velocity between two positions for the specific ocean environment (SVP and bathymetry) and is stored in tables in terms of various depths and depression/elevation angles. During the real-time localization process, only simple interpolations are required to obtain the effective sound velocity (which is significantly different from the true sound velocity at various depth locations) between the ship and target positions.

Title:Advanced Detection, Classification, and Avoidance Toolkit (ADCAT)
Abstract:The need for autonomous unmanned vehicles is becoming more evident. Unmanned surface vehicles (USVs) provide benefits ranging from manpower reduction and force multiplication, to performing missions too dangerous for manned platforms. One of the most critical challenges is the avoidance of obstacles. 21st Century Systems, Incorporated (21CSI) is in the right place at the right time with regard to this topic. Through various SBIR projects for the Navy and other services and agencies, we have developed and refined many of the pieces required to meet this challenge and are pleased to propose to address it. Through our considerable decision support expertise gleaned from development projects on behalf of many DOD agencies and melded with a state-of-the-art image processing technique, we propose to provide state-of-the-art object detection and classification for situation awareness and object avoidance. We call our concept the Advanced Detection, Classification, and Avoidance Toolkit (ADCAT). The general nature of our proposed solution and its expected effectiveness will make it applicable to a wide range of FNC unmanned vehicles. The ADCAT enabling technology, utilizing a computationally efficient algorithm that is robust with respect to geometrical transformations and spatial and temporal variations, will permit object detection and classification for unmanned vehicles.

Title:Object Avoidance for Unmanned Surface Vehicles (USVs)
Abstract:Daniel H. Wagner Associates, Inc. will develop an Object Avoidance for Unmanned Surface Vehicles (OAUSV) system that processes all available data, dynamically generates a Tactical Picture, an optimal route, and an object avoidance plan, and provides this information to the Unmanned Surface Vehicle (USV) control system and its operators. A key capability provided by OAUSV will be the ability to fuse data obtained by off-board systems (e.g., other ship's/aircraft/UVs' organic systems, Route Surveys, MCM systems) with own-USV data in real-time. In addition, we will utilize the contact data fusion and environmental data fusion algorithms developed in our Commander's Estimate of the Situation Tactical Decision Aid (CESTDA) and Current, Wind, and Wave Data Fusion (CWWDF) projects for ONR to determine a recommended route for the USV that minimizes ship vulnerability. As shown in our Cooperative Organic Mine Defense (COMID) work, the ability to utilize non-own-USV data will significantly improves the ability of the USV to maneuver around potentially threatening objects and dramatically reduces the number of false alarms. The primary algorithmic techniques that will be utilized in OAUSV are non-Gaussian and multiple hypothesis data registration and fusion, non-Gaussian optimization, and Bayesian inferential reasoning.

Title:SmartAvoidT - A Portable, Scalable Object Avoidance Solution for all Day/Night/Weather/Smoke Environments
Abstract:The primary objective of this SBIR effort is to develop a novel object avoidance algorithm dubbed SmartAvoidT. Unmanned vehicles of all types are faced with the common challenge of avoiding objects in the path of the unmanned vehicle. Until a robust, affordable object avoidance solution is provided, true autonomous operation on unmanned vehicles cannot be performed. Genex Technologies, Inc., a 3D and high-speed image processing company proposes to develop and integrate an object avoidance system for USVs. Our focus is to develop a novel object avoidance algorithm called SmartAvoidT that extracts multiple objects/targets out of video/imagery data, establishes individual tracks for each object and maps a path around each object to avoid collisions. The algorithm will then integrate with navigation systems to change course to avoid each object, continuously updating the "mapped" route. The primary innovation of our proposed SmartAvoidT algorithm is the adaptation of a multi-state-machine framework that uses a variety of object detection and target tracking methods to create robust inter-object `awareness' in high noise and cluttered (sea) environments. Our goal is to develop a reliable object avoidance algorithm that can provide robust location and history of the movement of multiple objects in real time within any imagery data (i.e. visible, near infrared, infrared, image intensified (I2), Ultra-Wideband (UWB), or any imagery yielding multiple targets within a stationary or moving background).

Title:Adaptive and Intelligent Object Avoidance for Unmanned Surface Vehicles (USVs)
Abstract:Automated object avoidance for Unmanned Surface Vehicle (USV) for both Navy (and DoD in general) and commercial applications has been the subject of much research and development over the past decades. The creation of a set of robust software tools for fully automated detection, classification/recognition and tracking of objects is vital in the development of an avoidance system for USVs. Without such tools the Navy operation of USV will require the existence of the man-in-the-loop (MITL) navigation. A multitude of current and future research and developments support the potential values and needs of autonomous systems. The use of truly autonomous USVs has been hampered by a lack of sophisticated and resource efficient obstacle avoidance systems. Current approaches have focused on either expensive active sensor systems or inferential processing techniques that are computationally intensive. In this proposal, UtopiaCompression and Defense Research Associate (UC/DRA) present an adaptive and intelligent system concept, using innovative algorithms in computer vision, mobile robotics, and computational intelligence, in particular Machine Learning (ML), which will facilitate true autonomous USV operations by providing a real-time, end-to-end solution tailored to Navy's sensor data and mission requirements using inexpensive imaging sensors and modest computational resources.

Title:Multi-purpose sensor module for valve control
Abstract:As part of the DDX and future Navy automated ship requirements, systems that were once controlled manually must now be controlled automatically or remotely. Control of mechanical systems requires feedback from sensors located at the device. Luna proposes to develop a multi-purpose sensor module for valve control and automation on board Navy ships. The module will be capable of either wired or wireless communication. Using battery powered wireless technology; this system is easily retrofitted onto existing ships, not requiring any new cable runs. Sensor data is transmitted to an application specific node for use in a control system, or to an Ethernet type node to make data available to multiple shipboard systems. On valves that are electrically controlled, the sensor module will have the option of wired power to prevent the need for periodic battery changes. The sensor will also have the capability of 0-10V or 4/20 milliamp output via a connector on the housing for systems that require wired communications. Standard pressure sensors will be used to interface with the module for measurement at any common pressure range. This same platform can also be used to measure parameters such as temperature, strain, and acceleration for other health monitoring applications.

Title:Embedded Pressure Sensors for Automation and Control of Fluid Valves
Abstract:The US Navy continues to research and develop advanced automation technologies to reduce the manning required to operate the next generation of combatants, without compromising platform survivability. One of the most manpower-intensive activities is damage control, during which time critical systems are shut down or re-routed to keep the ship operational. Sailors have typically been the only means of assessing and reacting to damage to a ship system1. For many systems, rapidly isolating damage and preventing loss of line media are critical to continued ship operation. Automated distributed control systems promise to greatly reduce reaction time and significantly reduce the numbers of sailors required during damage control operations by utilizing the following technology: Smart sensors to determine line pressure and fluid flow Smart valves to isolate damage Smart valves are now available that include controllers capable of communicating with sensors and other smart valves, each commonly referred to as "nodes" in the system. Depending on its location in the system, each smart valve is programmed to respond to information sent to it by other nodes, such as line pressure, fluid temperature, fluid flow, and whether other valves are open or closed. The primary Phase I Technical Objective is to assess the state-of-the-art in pressure and flow sensors and their applicability to smart fluid systems on Navy ships. From this information a recommendation will be made regarding the best available sensors that will meet the needs of the Navy. Marotta proposes to use a 3-step approach in order to achieve the stated Technical Objective. The first step of this SBIR will be to conduct an exhaustive survey of the market for pressure and flow sensors. The second step will be to select one or more of the most promising products or technologies and recommend design changes as required for the Navy ship environment. The final step will be to incorporate these sensors into a smart valve system, using LonWorks or other field bus, to provide the information necessary to monitor, troubleshoot and reroute the system around any damaged or non-functioning sections.

Title:Embedded Smart Pressure Sensors for Automation and Control of Fluid Valves
Abstract:The objective of our proposal is to demonstrate the feasibility of producing a low profile, small size, all stainless steel pressure sensors which is suitable for the automation control of fluidic valve (smart valve). This Phase I project will develop novel capacitive strain gage and eventually an all stainless steel pressure sensor will be developed using this new strain gage. Capacitive sensing is inherently high sensitive and near zero temperature effects. All stainless steel pressure design is rugged and suitable for harsh environment, such as, in salt water, hydraulic oil, lube oil, and even in heat exchangers. The strain gage will be batch fabricated using micromachining method, thus low cost. A commercially available very low power consumption wireless network will also be studied in Phase I. In Phase II, an ultra-miniature and low power consumption wireless network will be developed and will be incorporated with the newly design pressure sensor to form a complete package for automatic control of fluidic valve.

Title:A MEMS-Based Sensor for Automation and Control of Fluid Valves
Abstract:In this program, Orbital Research Inc. will enhance its current embedded pressure sensor technology, which previously has been demonstrated for sensing in-situ engine combustion events, for the automation and control of shipboard fluid valves. Precise control of high pressure fluidic systems is currently accomplished using high performance control valves. Performance of these valves can be improved by coupling them with local pressure sensors to allow feedback control. Adding data feedback to damage control, propulsion and other shipboard systems will enable improved safety, greater efficiency and better system survivability while requiring less manning. This proposal presents an innovative MEMS-based sensor system which exhibits very high sensitivity allowing it to be small and non-intrusive. Its material composition makes it very robust, chemically resistant, and survivable in a variety of environments, including salt water, lube oil, and hydraulic fluid. The MEMS fabrication technology makes it inherently inexpensive and allows flexibility in packaging to accommodate communication options. In this Phase I program, a sensor will be designed, and fabricated for laboratory testing to ensure robustness and prove the feasibility. The Phase II program will build on the Phase I through detailed design optimization including extensive full-scale prototype testing in a working fluid system. At the conclusion of this successful SBIR program, Orbital Research anticipates having a system ready for Phase III field evaluation on a future combatant platform such as DD(X).

Title:Embedded Pressure Sensors for Automation and Control of Fluid Valves
Abstract:The new pressure sensor/transmitter technology for marine flow valves represents enormous advantages over existing marine pressure measurement devices. The new technology would meet virtually all the U.S. Navy needs in flow pressure/rate sensing at a fraction of the cost of what it presently costs the Navy to purchase. These low cost "pliable" sensors can be directly integrated in piping and valving adjacent to the flow of fluids or gasses. The technology offers significantly more accurate sensor measurements than are presently available with `pressure diaphragm' or other resistive sensor related techniques. The manufacture is a low cost production process that can easily be geared from few to mass output levels. The devices themselves are immune to temperature drift and will be available in small/very low profile packaging size that is pliable and can be directly attached to the interior walls of pipes and fittings.

Title:Aerogel insulation blankets for shipboard noise suppression
Abstract:High noise levels on aircraft carriers from onboard flight operations impart tremendous implications, including miscommunication during combat and training, reduced crew combat effectiveness from stress and fatigue, and medical expenses from hearing damage. To mitigate the cost and safety concerns, Office of the Chief of Naval Operations Occupational Safety and Health Requirements stipulate that new ship designs incorporate acoustical treatments so that the equivalent noise level at watchstander stations is less than 84 dBA. To accomplish this objective, the Navy wants to develop new sound insulation which surpasses current state-of-the-art materials for passive noise reduction. Prior efforts have shown that aerogel insulation blankets, developed for thermal purposes only, have potential to absorb sound. On the proposed effort, Aspen Aerogels, Inc. will optimize those aerogel blanket materials specifically for acoustic noise suppression. Aspen will vary chemical composition, density, and pore size, as well as include hybrid material solutions. Phase II will scale up development and perform full testing needed to qualify the system for shipboard use. Overall, the proposed aerogel insulation will be cost effective, light-weight, and able to satisfy thermal, smoke, and fire barrier requirements.

Title:Acoustic, Thermal and Fire Insulation System
Abstract:The objective is to develop a new class of insulation coating that simultaneously targets noise, fire and condensation. A single coating which can fulfill all the requirements would be the ideal solution (Design A). Recently, QS completed R&D on a novel viscoelastic polymer for use in construction that provides superior sound damping along with fire protection in a single polymer blend. This is now in commercial use. Some of this technology, combined with ceramic microspheres, can be leveraged into a single coating. This one-component system, referred to as Design A, will be investigated as part of Phase 1. Alternatively, a lower risk Design B two-component coating system will also be investigated. The top component will be a thermal insulating coating consisting of microscopic air-filled ceramic and/or silicon microspheres to provide a fire, thermal insulation and condensation barrier. The bottom component will be QuietShip to damp noise and vibration. QS (and predecessor company) has been shipping acoustic damping viscoelastic polymer technologies for 12 years. It is now executing a project on the X-Craft using the same base polymer slated for the system. QS is confident that it will provide a breakthrough material to Navy as a result of this SBIR.

Title:Acoustic, Thermal and Fire Insulation System
Abstract:In recent years, significant strides have vastly improved the potential for spray on insulation systems that will help to abate airborne noise on Surface Ships. The optimal insulation will provide high acoustic absorption, airborne transmission loss and structural damping along with the requisite thermal/fire/condensation protection. Our objective is to exhibit improved acoustic characteristics through a liquid ceramic thermal insulation that provides NAVSEA approved condensation control. Combine this product with a tested fire retardant product that also displays damping capabilities. These products will produce a multi-modal or composite layered liquid applied barrier. This coating combination is safe, light weight and produces very little smoke. The concept will use proven ceramic micro-sphere technology that we have developed and designed over a 14 year period. The blending of micro spheres in a safe, light weight waterborne matrix has been accepted for use by industry and manufacturing in a wide array of circumstances. TECH 21 research will investigate how these products can be combined for maximum results. The conclusion will yield a method of blending and installation that will reduce handling, weight and installation costs. We will explore the incorporation of this system into the N98-092 JERICHO program and SNAME's Design Guide 3.37.

Title:Active Noise Reduction Technology
Abstract:The proposed effort will actively reduce noise from flight operations at watchstander stations below the flight deck to levels that do not require hearing protection. Long-term hearing loss of personnel is projected to cost the Navy on the order of $12.6 billion over a 30 year retirement period. Active noise reduction (ANR) has long been known as the best method of controlling low-frequency noise but has been limited by available technologies. Recent developments in modern control methods and microprocessors have made active noise reduction a practical, realizable solution for controlling low-frequency noise. Etrema Products, Inc. proposes to implement an ANR system to reduce noise levels from shipboard flight operations by >20 dBA over the frequency range from 50-800 Hz. The proposed approach uses a combination of active structural acoustic control and active noise cancellation by vibrating ship bulkheads and/or speaker panels to actively control noise in ship compartments using the magnetostrictive material, TERFENOL-D. The Phase I effort will be to generate a design concept, demonstrate its feasibility through modeling, and develop a concept validation plan. If successful, the proposed work will reduce costs to the Navy of long-term hearing loss and other detrimental effects of excessive noise exposure.

Title:Active Noise Reduction Technology
Abstract:Noise levels in crew compartments below the flight decks on Navy ships during flight operations have traditionally been extremely noisy due to jet engine noise as well as launch machinery transients. Levels exceed Navy desired levels by over 10 dB. Current state of the art materials do not work well at low frequencies. SSC proposes to develop an active noise solution that consists of a modular, fully integrated smart material that can be applied to the interior compartments of ships. The smart acoustic panel will reduce radiating noise by employing advanced smart materials such as polyvinylidene fluouride (PVDF) and lead zirconate titanate (PZT) actuation materials, embedded MEMs based acoustic and vibration sensors, and polyurethane foam for passive vibration absorption. A method to use smart acoustic materials to provide local noise control of manned spaces will also be investigated if global control proves to be unfeasible.

Abstract:Harmonia, Inc. proposes to address human/computer interface (HCI) issues faced by the DD(X) program by investigating new and "breakthrough" software tools that utilize the User Interface Markup Language (UIML). The proposed tools interface with commercial off-the-shelf products and are designed to streamline the HCI design and development process without forcing DD(X) personnel to significantly change the process they currently follow. The approach centers on working closely with the ship system integrator industry to form project execution and implementation teams; obtaining input from experienced individuals to focus on developing software technologies that promote commonality within the Total Ship Computing Environment (TSCE), thus adhering to the Navy's proposed Open Architecture Computing Environment guidelines and reducing lifecycle costs. Harmonia has identified six DD(X) engineering problem areas and possible UIML-based tools to address them. During Phase I Harmonia will define requirements, identify potential risks, conduct selected prototyping activities, and assess the commercial viability of each technology to determine which have the most potential benefit for the DD(X) program and should thus be prototyped in Phase II

Abstract:RLW proposes to design and demonstrate a TSCE-I compliant "micro" Distributed Adaptation Processor (DAP) by incorporating a modified TSCE client into its SxNAP(TM) family of products. This will provide a family of "Small, low cost peripheral data collection and legacy system interface" options for DD(X) and other DoD and commercial platforms. The SxNAP family has been developed over the last five years to provide a hardware/software platform to enable connection of any analog sensor to any network. The SxNAP devices provide signal conditioning and sensor power, local processing to apply algorithms and logic to sensor data (reduce bandwidth and enable limited local closed-loop control), and communications to manage the network interface and format the data. The family spans multi-sensor/high processing power applications for vibration analysis to single sensor/low processing power applications for monitoring distributed parameter values (temperature, pressure). Our efforts to date have focused on an XML interface over wired and wireless (802.11b/g) TCP/IP networks, but the platform has been designed to accommodate any network interface. This project will adapt and port the TSCE Client onto a low-cost microprocessor/microcontroller platform - the SxNAP Network Processor.

Title:Stable Platform Module for Ships
Abstract:There exists many potential applications for stable platform technology on Navy as well as commercial vessels. One such application is launching and recovering UAVs and VTUAVs on ships at sea. Without a stable launch and recovery platform that eliminates ship accelerations, operation of the unmanned aerial vehicles from ships is difficult. Although stabilization systems for orientational degrees of freedom are common on ships (e.g., consider fire control systems and stabilized antennas), systems that provide stabilization for both orientation and large changes in position are not. We propose to develop a concept that can provide full stabilization (i.e., in both position and orientation) that would greatly facilitate a UAV and VTUAV operation on ships and that can be adapted to other applications such as at-sea transfer of cargo and personnel. A dynamic simulation of the proposed stable platform module will be developed and candidate COTS hardware and suitable low-level control architectures will be identified. System requirements will be refined and critical derived requirements, including ship motion sensing, will be established. The results of the phase I effort will allow for a smooth transition to the hardware prototype development for phase II.

Abstract:SatCon proposes a stable platform module for the launch and recovery of UAVs from the decks of Navy Ships. This platform will accommodate large amplitude motions in roll, pitch and heave enabling wide spread use of UAV systems on smaller Navy ships over a wide range of sea sates and vessel speeds. The platform will utilize an innovative folding actuator system that allows large vertical displacements while providing for a low profile installation without intruding below the deck. The fully electric actuator system will require very little maintenance reducing operating cost and manning requirements. In Phase I we will assess launch and recovery requirements for a variety of UAV/UAS, deck motion characteristics of Navy and commercial ships and determine requirements for platform size, amplitudes of actuator motion, and necessary control bandwidths. Also in Phase one a preliminary design of the prototype Stable Platform Module will be generated. Detailed structural analysis and dynamic simulations will be performed in a Phase I option. A full-scale prototype will build and evaluated in the subsequent Phase II program.

Title:Large Format Monolithic CCD Camera
Abstract:A primary limitation to the implementation of new ground-based astronomy measurement techniques is the inaccuracy of navigation and targeting due to error in the celestial frame of reference. This celestial frame of reference is relied upon for satellite attitude determination, payload calibration, in-course missile adjustments, space surveillance, and accurate star positions used as fiducial points. The development of an ultrahigh resolution CCD (up to the limit of a 150 mm wafer) that integrates high dynamic range and fast readout will substantially decrease the error in the celestial reference frame. New developments within semiconductor fabrication, along with a mature CCD processing, will alleviate yield issues and improve cosmetic quality. New process technologies including high-k gate dielectrics, shallow trench isolation, chemical-mechanical processing, and combination stepper-scanner capabilities, aid in large area yield, improved charge transfer efficiency (CTE), fast readout, decreased RMS noise, and improved CCD sensitivity. Semiconductor Technology Associates proposes a solution which will identify and integrate the appropriate new semiconductor technology advancements to existing CCD processing recipes to yield large area ultrahigh resolution imager systems.

The analysis will include new developments in platform technology, advances in the OTEC process, and alternate fuels to hydrogen which may be more advantageous for at-sea production, storage and transportation. The study will lead toward the development of a trial or prototype at-sea plant to supply hydrogen (or alternate fuels) for the US Navy or civilian users.

Title:Automated Swimmer Recongition Algorithms for the HarborGuard Intrusion Detection System
Abstract:The remote identification of surfaced swimmers in a harbor environment is a critical requirement for a comprehensive waterside security system. This requirement can be clearly divided into detection and classification objectives. Detection in this context means identifying the presence of a target on the surface of the water. Classification means discriminating between different types of targets - specifically, discriminating between swimmers on the surface and non-swimmer targets, such as birds and floating debris. Barron Associates, Inc. (BAI) has teamed with L-3 Communications Klein Associates to propose an SBIR program that leverages the industry-leading HarborGuard waterside security intrusion detection system manufactured by Klein. The Klein HarborGuard already provides detection capability that exceeds the requirements set forth in the SBIR solicitation. The objective of this SBIR effort is to enhance the HarborGuard with sophisticated automatic target classification algorithms designed to reliably recognize surfaced swimmers with a low occurrence of false alarms even in the presence of many non-swimmer surface targets. BAI and Klein will collect extensive sensor data that BAI will use to develop and test a reliable automated swimmer recognition (ASR) algorithm. If successful, the enhanced HarborGuard will meet or exceed all of the requirements set forth in the SBIR solicitation.

Title:Development of a Sensor System for Reliable, Automated Detection of Surfaced Swimmers
Abstract:Metron proposes to develop Likelihood Ratio Tracking (LRT) for available Commercial Off The Shelf (COTS) sensor systems to automatically detect unauthorized swimmers in the water around key instillations and ships. Metron proposes to team with a producer of COTS sensor systems (such as Klein Associates, Inc. or Thales) where we can draw on extensive experience in using LRT in various successful Anti-Submarine Warfare (ASW) applications. The LRT methodology has proven effective in reducing false alarms and clutter in radar detection of periscopes in heavy clutter, and we believe that this same methodology could dramatically improve the performance of current COTS systems.

Title:Ultra Wideband Radio for Secure Communications in a Noisy Environment
Abstract:The innovation of this proposal involves ultra wideband (UWB) radios for secure communications between the inner element of a gimbaled system and an external computer. We propose to install one UWB radio on the inner components of the gimbaled system and another one on the inner surface of the aluminum sphere. The second radio is connected to the external computer through a wired connection depending on the data rate. Because UWB radios are wireless, they will not be affected by debris or moisture on the slip rings of the gimbaled system. Its interference to other narrowband communication systems is negligible so it can easily satisfy electromagnetic interference (EMI) standards. This is because the transmission power of UWB signals is distributed over a huge bandwidth and the power spectrum is usually below the environmental noise level. It is also very difficult to detect UWB radio signals due to their noise-like spectral characteristics. Another characteristic of UWB radio is that it is much simpler than conventional radio, which allows us to develop a miniaturized and light-weight UWB radio. All these features make UWB radios an ideal candidate for communications in Navy gimbaled systems.

Title:Data Fusion for Geophysical Aided Navigation Technologies
Abstract:Many moving platforms, including SSBNs and SSGNs, rely on inertial navigation systems for position and velocity information, either as the primary navigation system or as a backup system. Because of drifts in critical hardware components, INS systems must be periodically reset using occasional position fixes from a sensor, or sensors, external to the INS. There are numerous candidates for the reset mechanism, including GPS, celestial, terrain, bathymetric, gravimetric, and magnetic fixes. The overall objective of the proposed Phase I effort is to develop a particle filter based mechanization for fusing geophysical data (bathymetric, gravitational and magnetic) with platform INS data in order to provide a cost-effective high-accuracy navigation solution over extended, perhaps indefinite, endurance intervals. This will provide the basis to develop the Phase II demonstration system.

Title:Ants on the AEDGE
Abstract:When the call comes in to respond to a time critical target, there is little time for the watchstander to weigh the myriad factors that go into targeting decisions. We know where the target is now, but where will it be when the weapon system arrives to engage it? In order to plan for an effective mission, the planner and watchstander must have an effective movement prediction on known surface vehicles. This prediction should take into consideration vehicle capabilities, the vehicle's environment, and updated observations of the vehicles in question. The prediction technique should also provide the operator/watchstander with a sense of the uncertainty in the prediction based on time elapsed since last observation and possible alternate paths. 21st Century Systems, Incorporated is pleased to address this prediction challenge by utilizing a recent innovation in algorithms derived from nature. 21CSI proposes to use an ant-based algorithm for predicting the future location of a surface vehicle that incorporates vehicle capabilities, previous history, and vehicle environment in its determination. The algorithm includes support for updated vehicle observations and uncertainty regions. We call our concept Ants on the AEDGE (an ant colony paradigm algorithm using the COTS AEDGE environment).

Title:Applying Computer Game Technology to the Display and Visualization of Movement Predictions for Ground Vehicles
Abstract:Applied Visions, Inc.(AVI) proposes to leverage the technology of computer games to provide a powerful new method of visualizing the potential movement of ground targets and threats for op-erators of the Tactical Tomahawk Weapon Control System (TTWCS). Recent advancements in the multi-billion dollar game industry have produced game engines that combine powerful visual rendering with sophisticated simulation of real-world physics and vehi-cle dynamics. Our research will be aimed at adapting these game engines to: a) simulate the ability of different target and threat vehicles to move through their local terrain, and b) to generate realistic 3D views of the predicted future movement. Combining AVI's extensive background in 3D visualization and military simulation with game engine experience gained in a recent SBIR for the Army, our Phase I effort will be devoted to defining the key requirements of the system, evaluating representative game engines, and implementing an early prototype to demonstrate the feasibility of the concept. Our Phase II effort will refine the architecture, upgrade the prototype to interface to the TTWCS and participate in field trials.

Title:Using Machine Vision Techniques to Create a Multi-Resolution Obstacle Database
Abstract:The Navy requires an architecture for acquiring and storing 3-Dimensional obstacle data. An extension of the Terrain Awareness Warning System (eTAWS), the obstacle database must store man-made objects such as buildings, bridges, towers, overpasses, and wires. The system must be able to generate obstacle database data from a number of sources including synthetic aperture radar (SAR), stereo/multiple aerial/satellite photography, and raw geodetic survey data.Cybernet proposes to focus on the collection of 3D obstacle geometry/location based on aerial photography and using advance image processing techniques. This collection process will then be used to populate an indexed database that stores obstacle data at multiple resolutions. By indexing the data, we will be able to reduce the storage requirements by storing redundant data only once. By storing the data at multiple resolutions we allow the application accessing it to balance the tradeoffs corresponding to the different levels of resolution/detail, such as resolution vs. coverage area.

Abstract:The objective of this proposal is to develop a method for the automated extraction of man-made obstacles from air and space borne digital imagery. The goal is to achieve detection accuracy of 20 feet vertical over an observation area of 1000 km2 or more. The approach taken to meeting the objective is systematic, model based and applicable to a large number of available observation platforms, near earth as well as orbital without the need to provide specialized optics. The approach employs the use of a single lens imager coupled with positional as well as attitude information. By being systematic and model based, all error sources will be modeled allowing us to develop a methodology applicable to the performance requirements. The quality of the information is expected to be sufficiently good to support the field operational use, while being straightforward in implementation to support a range of users.

Title:Object/Target Discrimination, Recognition, and Identification
Abstract:AMPAC, under contract to the Navy, has developed a deterministic, software-only Decoy Detection Algorithm, based on a mathematically proven if-and-only-if theorem, which uses mathematical concepts that rely on geometric features (points and lines) to deduce planar qualities - object is 2-dimensional or not. It uses linear algebra on small matrices (~ 20 x 20) and is mathematically exact - limited only by image resolution and quality. The algorithm requires two sets of correlated straight line segment endpoint data obtained from two images of the object of interest taken from sufficiently different perspectives. It has been developed to be used with EO sensors, is based on the pin-hole camera model, and is applicable to visible bands, IR, UV, etc. No pre-mission object data is required: databases, templates, etc. No camera data - location, orientation, construction - is required. Images do not need to be orthorectified. A prototype software system (where a human operator specifies the object of interest) is being developed to accept images from a host/sensor, generate inputs for the Decoy Detection Algorithm, call that algorithm to obtain an answer, and then pass that answer to the host/operator.

Title:Object/Target Discrimination, Recognition, and Identification
Abstract:Automatic target recognition independent of range and orientation is achieved by using a very different type and much reduced quantity (fewer pixels) of visual information, easily derived from the output of any standard image sensor by variance sub-sampling. The very low pixel density of the resulting variance image directly provides (1) high pose-immunity in any one target-reference match, and (2) enables multiple (variance) references to be stored of each target type to provide coverage over the full set of required poses. In spite of its low pixel density, variance sampling provides high resolution information essential for recognition. Conventional Nyquist sampling, on the other hand, requires high pixel density to provide the essential high resolution information and is thereby highly pose-sensitive and also highly processing and memory intensive. This very different (variance) and much reduced quantity of visual information is used almost exclusively by human vision to perform recognition. Its transition to ATR systems, that seek to emulate human vision, will result in a major advance in ATR capability.

Title:Object/Target Discrimination, Recognition, and Identification
Abstract:This proposal will allow systems using an input of one EO target image with a stored feature database of target geometric features (points/lines) to identify the target from the feature pattern in the EO image. A key advantage is that this is done from the imaged target features alone without data on the camera position/orientation relative to the target. The present goal is to develop software modules to overcome two key limits on this approach : 1) noise/errors in extracted target features in an EO image and 2)distinguish decoys from targets. If successful,it will seperate real targets from decoys using a robust software system containing these modules.

Title:Hypersonic Alumina Infrared Domes
Abstract:CeraNova Corporation proposes to produce ogive missile domes of its transparent polycrystalline alumina (PCA) as an advanced material for this application. PCA has the same intrinsic properties as sapphire, but can be manufactured using the proposed low-cost powder processing method allowing for near-net-shape manufacturing. Like sapphire, PCA offers excellent erosion and wear resistance due to its high hardness, combined with good strength and toughness. CeraNova recently demonstrated a low-cost, powder processing route for producing transparent, fine-grained PCA disks that has the potential to meet or exceed the capabilities of sapphire in demanding infrared window and dome applications. The disks displayed low scattering and good in-line transmittance, particularly in the 3-5 m range. CeraNova's proposed approach is to produce near-net ogive shapes using a casting method demonstrated for small PCA components. The feasibility of grinding and polishing ogive shapes will be studied by teaming with other laboratories who have expertise and unique capabilities for figuring and optical polishing of hard ceramic materials. The uniform polycrystalline microstructure, increased hardness and toughness, and potential for near-net shape processing for CeraNova PCA present significant advantages for this material in infrared window and dome applications for high speed ogive missiles.

Title:The Affordable Production of Hypersonic Missile Ogives Using Innovative Processing Techniques
Abstract:Creare proposes to develop a super-hard, optical quality tangent ogive from polycrystalline alumina (PCA) using innovative sintering techniques and a novel laser-assisted, ultra-precision machining system. Contrary to sapphire blanks, which are costly to grow, PCA near-net shape parts are made using an affordable powder-based process; however, no affordable manufacturing techniques are currently available to produce the large-scale PCA near-net shape blanks or to shape and polish them into a tangent ogive. Proprietary sintering processes to produce large-scale PCA near-net shape blanks will be combined with a novel processing technique to enable the affordable production of an optical quality ogive. Our novel processing technique is based on a unique, laser-assisted, ultra-precision machining system that enables the production of complex shapes quickly and affordably with significantly higher material removal rates (MRRs) than state-of-the-art processing and polishing techniques. Our novel processing technique relaxes the dimensional tolerances of the sintered part and, thereby, dramatically reduces the overall cost of the production process. In addition, our unique processing technique can produce optical quality surfaces on the interior and exterior of the ogive, which is not possible with current optical polishing processes. Thus, our innovation is effective, affordable, and flexible.

Title:Hypersonic Infrared Dome
Abstract:In order to enhance missile performance, future missile designs will incorporate domes with a more aerodynamic shape than the traditional hemisphere. Significant additional benefits in areas of performance and cost reduction would be realized if a new material with more robust properties and the ability to be formed to near net shape replaced more common materials, such as sapphire. One promising replacement is polycrystalline alumina (PCA) with sub-micron grain size. It can be made to have improved toughness and nearly the same optical transmission in the mid-wave infrared (MWIR) band as sapphire. There is no established fabrication process suitable for this material or the aerodynamic shapes of interest; conventional finishing processes used to manufacture flat and spherical optics are not appropriate for such complex shapes. A process that utilizes deterministic micro-grinding, Magnetorheological Finishing (MRF) and newly developed MR Jet provides significant and unique advantages for finishing both the convex and concave surfaces of such conformal shapes. Work in Phase I will demonstrate: 1) a full manufacturing process on PCA flats from material blank through final polishing that meets transmission specifications and 2) the ability to fabricate precision domes with the proposed process. Successful completion of Phase I activities will enable the manufacture of PCA ogives during Phase II.

Title:Handheld Real-Aperture Radar and EO Fusion for LO Vehicle RCS Verification in Uncontrolled Environments
Abstract:Portable RCS verification systems that can be forward-deployed with low-observable (LO) aircraft, offer the potential to dramatically improve aircraft survivability and mission effectiveness. Modern LO aircraft with short- or vertical takeoff capabilities are designed to operate effectively without the need for runways and other facilities. Such an operational environment presents unique challenges to RCS verification equipment. ALPHATECH, and its subcontractor, ATK-Mission Research Corporation (MRC), understand these issues and propose a systematic design study that leverages our combined experience. ALPHATECH and MRC propose: Real aperture: We will investigate replacing SAR operation and processing with a real aperture approach. This approach may solve the challenges of data collection, motion compensation, image processing, and association of measurements with specifications. Miniature RF components: We plan to use RF components developed by the cell phone and wireless communications industry in our radar design. These components are small, cheap, efficient, and provide the building block to generate low-probability-of-intercept (LPI) waveforms. Radar/EO fusion: We will use a boresighted video camera to aid association of RCS imagery with an aircraft wireframe, RCS specifications, and previous RCS images.

Title:Portable Handheld Imaging Radar System Technology
Abstract:Handheld radar RCS imaging could be a boon to maintainers of LO aircraft, enabling flight-line validation of maintenance actions and pre-flight mission readiness assessment. To date no system has been able to fulfill this promise. We believe that Synthetic Aperture Radar offers the best technology to solve the problems of high sensitivity, wide aperture, dense along-track element spacing, and wide frequency operation in a very small, lightweight package. In 2000-2001 we prototyped a handheld SAR radar and concluded that an accurate position measurement system was the missing piece needed to create a fieldable capability. This system should operate an aircraft reference coordinates. It should guide the user in forming an aperture so that baseline geometries can be reproduced. The position data should be used to assist image formation. In Phase 1, we propose to demonstrate the feasibility of an integrated system composed of position measurement,motion compensation, and image registration that will produce high quality imagery.

Title:Enhanced Data Link Performance in Multipath and Interference Environments
Abstract:The proposed solution utilizes multiple antenna installations employed in strategically chosen locations on the aircraft carrier to maximize the system's capability to reject multi-path and interference. Each antenna installation employs unique techniques to mitigate the multi-path and interference problems individually or part of a larger system. The key to the system is to combine multiple antenna platforms with unique characteristics into a diverse system. A diverse antenna system which exploits spatial diversity between apertures, frequency diversity, and amplitude diversity within an aperture will provide significant advantages over traditional systems. The three antenna platforms are presented as the optimal approach to attain coverage in the critical regions and mitigate the effects of multi-path and interference. The three antennas can each function as stand alone systems or be combined to form a system providing higher spatial specificity if required. FIRST RF personnel have both past and present history in the understanding, exploitation, and mitigation of multi-path to apply to this problem. FIRST RF has developed innovative beamforming techniques including non-traditional beam/null forming algorithms to maximize rejection of an interference signal. Finally, FIRST RF has validated our models using scaled measurements on the carrier for multi-path predictions and pattern performance.

The digitized RF UHF signals are processed in correlation-based rake receiver and their multipaths are combined using high-performance multiplier to eliminate multipath fading. This program will capitalize on prior and continuing DoD programs at HYPRES developing digital-RF receiver systems using superconducting components.

Title:High-Dynamic-Range Digital-RF Receiver with Rapidly Tunable Notch Filters for Cosite Interference Reduction
Abstract:HYPRES proposes a two-pronged approach to reducing co-site interference: (1) Tunable notch filters to track one or more narrow-band jamming signals. (2) The use of a sensitive digital-RF receiver with high spur-free dynamic range (SFDR), which can tolerate high inteference levels without saturation. Together, these techniques can reduce the inteference to an acceptable level. We further propose to evaulate the feasibility of implementing both of these using superconducting components. These include: (1) Thin-film RF analog notch filters based on high-temperature superconductors (HTS), rapidly tunable by either micromechanical, optical, or thermal means. (2) A digital receiver built using ultrafast low-temperature superconducting (LTS) digital integrated circuits, with SFDR greater than 100 dB. Several possible receiver architectures will be investigated, including active cancelation and subranging. Both HTS and LTS components can be integrated together using a compact, multi-stage cryocooler, so that the entire system can operate without the need for liquid cryogens. This builds on prior and continuing DoD programs at HYPRES developing digital-RF receiver systems using superconducting components.

Title:Cosite Interference Reduction for Electronic Attack Aircraft
Abstract:Reducing cosite interference on an aircraft requires a top-down system engineering approach. This begins with collecting performance data on all equipment involved, computer modeling the interference for each equipment pairing to identify specific interference sources and levels, defining the amount of mitigation necessary for each pairing, and designing a subsystem that provides the needed mitigation. Softronics Ltd. will apply its years of cosite engineering experience and its proprietary cosite interference computer model to quickly determine the mitigation needs of the EA-18G. Solutions are expected to varying with the equipment pairing, and to involve a combination of operational rules and technology, from frequency management to fixed and agile filters and notches, to adaptive cancellation systems. A key feature of our approach is that it may be incrementally implemented on any aircraft or vehicle.

Title:Cosite Interference Reduction for Electronic Attack Aircraft
Abstract:Modern military aircraft carry many microwave and RF systems which must operate in close proximity to one another. Radio frequency interference (RFI) is virtually inevitable. The EA-6B Prowler electronic warfare (EW) aircraft presents a particularly severe interoperability problem because its primary mission is to jam enemy radars. Specifically, the performance of life-critical identification, friend or foe (IFF) systems is degraded by spurious signals and harmonics from on-board jamming systems. Toyon Research Corporation proposes to design a shaped-pattern antenna or antennas to combat radio frequency interference to IFF and Link 16 systems on the EA-6B. We will use our novel anti-jam fixed reception pattern antenna (AJ-FRPA) design techniques to develop an antenna whose pattern is shaped to maximize isolation between the victim antenna and the jamming antenna. This antenna will be compact, passive, and a drop-in replacement for existing antennas on the aircraft.

Abstract:A new airborne electronic warfare pod is being developed for the EA-18 aircraft that will be entering service to replace the aging EA-6B.

An innovative ram air turbine, customized to produce power and provide cooling that will be located entirely within EA-18 pod, is proposed. CFD Research Corporation has teamed with Curtiss-Wright Flow Control - ElectroMechanical Division (CWFC-EMD) to minimize technical and commercialization risk during development of this new ram air turbine unit. CFDRC will lead the design and development of the turbine, inlet, and cooling systems. EMD will be task with adaptation of their existing generator to meet new Navy requirements. Phase I will focus on preliminary and detail design and analysis to assure all solicitation and EA-18 operational requirements are exceeded. Phase II will focus on fabrication, test, evaluation, and prototype delivery to the Navy. Our strategic alliance with CWFC-EMD, a supplier of power and cooling units to the Navy for over 50 years, will facilitate rapid Phase III commercialization.

Title:Development of a Compact Power Generation Turbine and Cooling System
Abstract:Military aircraft currently utilize an externally bladed ram air turbine to provide electrical power for military stores (pods). This current system has several disadvantages, first, an externally blade turbine located at the cone of the pod increases the aerodynamic drag of the aircraft. Second, with the turbine located at the leading edge of the pod, the forward end of the advanced technology tactical jamming pod can not be utilized for jamming equipment. Mainstream Engineering has developed an innovative method to locate a turbine internally in the military stores. This system is capable of generating the required power for equipment such as the advanced technology tactical jamming pod for the EA-18G advanced airborne electronic attack aircraft. In addition to electrical generation ability, a novel approach for providing active cooling for electronic equipment aboard the pod has been developed. The proposed system has significant advantages over ram air turbines currently used by DoD.

Title:Advanced Nonskid Coating System for Mobile Airfield Landing Mats
Abstract:Marine Corps AM2 mats are formed from Aluminum alloy 6061-T6 and are currently coated with an epoxy-based nonskid coating. Due to the wear and breakdown by the environments such as high temperature aircraft engine exhaust and aircraft landing impacts, this coating requires frequent replacement. The thermal spray technology is environmentally friendly process and Demeton successfully replaced the environmentally unfriendly Hard Chrome Plating in previous SBIR project. Demeton_s patented technologies, Demeton Detonation Spray Process(DDSP) and Twin-Chamber HVOF, can provide the premium nonskid coating properties including high bonding strength, high wear and corrosion resistance, and high heat resistance. DDSP keeps the substrate temperature very low with the unique characteristics of the detonation wave and can provide the very dense coating with highest bonding strength onto the aluminum surface of AM2 mats. TC-HVOF can provide the nonskid coating with high productivity. Demeton combines both technologies to provide the nonskid coatings, which meet the every requirement by Marine Corps AM2 mats, with the high productivity for the lowest cost.

Title:Advanced Nonskid Coating System for Mobile Airfield Landing Mats
Abstract:The Marine Corps AM2 mat is a key component to the Marine Corps Expeditionary Airfield concept. These mats are robust and able to withstand tailhook impact and the landing loads imposed by aircraft even when installed over marginal soil conditions. The current coating needs frequent replacement due to wear or breakdown from the environment. Very importantly, the coating is required to withstand continued VTOL jet blast, which can sustain temperatures near 800 F and occasionally spike to 1000 F (for 0.2 second). This proposal summarizes work to be performed in the adaptation, testing and evaluation of TRI's Tough Grip nonskid coating to Marine landing strip use. This new non-skid coating, developed for aircraft carrier flight decks contains no added volatile organic compounds or other materials restricted by military environmental requirements, it is highly flame and impact resistant and has survived over 13,000 landings in battlefield conditions. A selected sample of modifications to this product will increase its tolerance to the conditions of VTOL engine exhaust.

Title:Detecting Target Maneuvers with the Radar Range Rate Measurement
Abstract:Currently, tracking systems cannot accurately determine when to switch algorithm classes of motion models: one for maneuvering targets and one for non-maneuvering (constant velocity and acceleration) targets, which results in tracking errors. These errors from the estimate target position relative to the targets absolute position can be very large when an incorrect motion model is applied. However, this error can be reduced by exploiting the radar range rate information to identify when a target begins a maneuver to improve target tracking. If this characterization can be successfully applied, then a tracking system can determine when to switch the applied algorithms from a non-maneuvering set to the maneuvering set to increase its accuracy and to provide a more realistic image to the radar operator. To determine the feasibility and potential benefits of using the radar range rate measurement, a prototype E-2C radar simulation will be developed. The successful development of this simulator will enable the design and build of a validated prototype maneuver detection algorithms and software.

Title:A Novel Target Maneuver Detection Technique with Range Rate Measurement
Abstract:We propose a novel target maneuver detection technique using radar measurement including range rate for tracking and surveillance systems to reliably indicate the presence and magnitude of target maneuvers. There are several innovative elements in our approach: 1) a reliable test statistic indicating target maneuver and guaranteed quickest detection; 2) incorporating maneuver detection algorithm into tracker design to improve tracking accuracy during target maneuver; 3) quantitative measure of the benefit in using range rate measurement for maneuver detection and target tracking for E-2C s operational scenarios; 4) a multi-sensor fusion technique to enhance the reliability of maneuver detection. A generalized Page s test, using a target acceleration statistic obtained from range, bearing and range rate measurement, and utilizing a bank of cumulative sum tests, will be used to detect target maneuver and magnitude. The test provides the shortest detection delay under given false alarm constraint and does not require the exact target maneuver model. A measurement conversion technique will treat the range rate as a linear measurement in Cartesian coordinates so that standard Kalman filter can be used in the tracker design. The approach is computationally efficient and avoids using the extended Kalman filter to incorporate the range rate measurement.

Title:Rugged, Low-Cost, Nondielectric Missile Radome
Abstract:Missiles will soon have the capability of traveling at higher speeds and over longer ranges than previously possible, resulting in uniquely demanding radome requirements. As seeker technology has been evolving to higher frequencies from X-band through W-band, traditional dielectric radome designs have struggled to meet the evolving requirements in electrical performance and environmental survivability while remaining affordable and easy to manufacture. Though electrically suitable, sandwiched radomes require costly processes with manufacturing tolerances becoming progressively more demanding with increases in frequencies used by RF systems. Alternate radome designs are desired that can be manufactured and characterized using simple materials and processes. A novel radome is proposed that uses a combination of conductors and dielectrics. The use of metal radomes with slots and holes are of particular interest as simple machining and filling of holes in a metallic aerodynamic dome will provide a very simple, producible, low loss, rugged design. The design is based on thick wall FSS technology that has been applied to radomes in the past. Modern numerical analysis allows efficient optimization of the design.

Our phase one effort will include characterizing plasma frequency selective surfaces, plasma cylindrical annular rings made of Synfoam, compare plasma FSS embedded in synthetic foam with metal FSS with Synfoam embedded in the slots, and hybrid metal plasma FSS with synthetic foamsupport structures. We will test these designs from 0 up to 40 or 100 GHz (Ka or W-band), and thermal modeling. We will investigate machined and cast radomes, plasma FSS radomes with tubes embedded in synthetic foam, metal slot radomes with slots filled with Synfoam, , and hybrid models with the apertures filled with synthetic foam.

Title:A Multi-Level Secure High-Speed Shared Memory Interconnect
Abstract:The military and intelligence communities seek computing systems that can safely share information with different degrees of confidentiality. Systems achieving that goal are said to operate in multi-level mode, which indicates that the system contains information at several different levels of confidentiality but cannot share information with unauthorized users. Communities requiring multi-level systems also demand a high level of confidence that they operate correctly, since leaked intelligence data could potentially destroy the effectiveness of extremely expensive intelligence gathering systems. A system or device achieves the objective of being "multilevel secure" if it can handle information at a variety of sensitivity levels without disclosing information to an unauthorized person. Implementations of fabric based solutions include processing elements that also contain direct memory access (DMA) nodes. These are programmable, such that data movements between processing elements of data residing within memory systems local to each processing are handled by the nodes and switched fabric crossbars. Aeronix is proposing to develop a high assurance, Multi-level secure, high speed, shared memory interconnect system capable of accreditation by NSA and/or other agencies. The main component of the system is a modified interconnect system architecture such as Rapid -IO, modifications will address multi-level security, use of shared-memory, and high assurance.

Title:A Hardware Implementation of Multi-Level Security in Real Time Shared-Memory Avionic Systems
Abstract:Rydal Research proposes to develop a high speed low-latency hardware-based implementation of multi-level security in a high-performance COTS protocol. The proposed method involves adding a sensitivity field to the Transport Layer header. Support for packet filtering will be added within the existing protocol specification. An additional error code will be developed to indicate errors and security violations in the filtering hardware. One or more real-time operating systems will be selected and the sensitivity level conveyed to the network interface via the operating system kernels. Fine-grain modeling and simulation will be used to determine the impact of the protocol modifications on system performance. An analysis will also be performed to determine the susceptibility and response of the protocol to intentional and unintentional security violations. All components needed to implement a complete system will be developed and demonstrated in Phase I in an FPGA-based prototype using Rydal's reconfigurable computing platform and low-latency network switch. Flexible, robust, and easy-to-use software support will also be provided for system bring-up, maintenance, and troubleshooting. RapidIO will be used for the initial implementation but the techniques developed will be sufficiently flexible that they can be used with any other high-performance protocol.

Title:SystemC Environment for FPGA Design, Verification and Transparent Technology Update/Upgrade
Abstract:Heterogeneous processing systems currently contain a continuum of processing alternatives from general purpose processors, to digital signal processors, to FPGAs and ASICs. Especially the Field Programmable Gate Arrays (FPGA) domain has recently produced its own range of architectural alternatives along that processing continuum spectrum. Given this richness of alternatives, optimization has been non-trivial for initial design, as well as for updates/upgrades. Pentum Group, Inc. (PGI) proposes to develop an FPGA programming environment based on SystemVSIPL, an open source signal and image processing library architecture developed by PGI. SystemVSIPL is based on SystemC, which is currently the most widely used language for whole hardware system design and simulation. SystemVSIPL extends the benefits of the open source VSIPL and VSIPL++ signal and image processing standards providing an open component-like library that can run on all current and future FPGA systems with excellent performance.

Title:Component-Oriented Operating Logic for FPGAs (COOL FPGA)
Abstract:The Navy Joint Strike Fighter program has a need for a design methodology to develop logic designs for large, complex FPGA-based systems. This methodology should allow FPGA logic created for one version of the on-board avionics hardware to be easily transitioned to more advanced versions. The goal is to avoid major revisions and extensive regression testing of the FPGA application logic. To address these needs, Systran Federal Corp. proposes a system called the Component-Oriented Operating Logic for FPGAs (COOL-FPGA). COOL-FPGA will act as an abstraction layer between the hardware and the application logic. The objective is to isolate FPGA application logic from hardware-specific details of the platform on which the logic is running. When the FPGA logic is ported to new hardware, only the Operating Logic will require extensive modifications; the application logic will require minimal updating. "Component-Oriented" indicates that FPGA applications built using this Operating Logic are meant to be created as discrete modules that are highly isolated from each other. The project will also include two software tools: the Application Builder, that enables COOL-FPGA application development, and the System Analyzer, that supports high-level simulation and analysis of multiple FPGA applications running on a single platform.

Abstract:We propose to develop a methodology and set of related products that allow FPGA applications to be hardware independent (allowing easy migration to new FPGAs), facilitate easy upgrade to add new firmware functionality, and reduce regression testing after system upgrades.

The innovations that this framework will offer include a formalized structured approach for the design and implementation of RC-Enabled systems (eliminating manual, ad-hoc development methods), support for Runtime Reconfiguration (RTR) activities (the dynamic modification of the functional configuration of the RC hardware), a unique approach for providing software control over the RC component configuration, a powerful solution for supporting communication between software executing on a general purpose processor and the RC functionality, and the transition of software fault-tolerance techniques to the RC component domain.

Title:Light Detection and Ranging (LIDAR) Surface Feature Extraction Tool
Abstract:The proposed effort will demonstrate a new approach to fully automated extraction of texture mapped 3D polygonal descriptions of manmade objects from multiple viewpoint LIDAR data and co-registered visible imagery. We will apply robust algorithms that have shown excellent results in use with LIDAR imagery for automated targeting applications. Expert system techniques based on typical building layout will be used to better separate building features from natural clutter. Once extracted, building descriptions will be constrained to fit common-sense properties of human building design, allowing the polygonal descriptions to be significantly simplified while retaining high standards of accuracy. Once fully proven in this domain, our algorithmic techniques will be extended to show the feasibility of future goals. Our Phase I and Option effort will demonstrate that databases produced can be run in real-time without exceeding commercially available graphics and processing hardware limitations, and will lay the groundwork for a Phase II demonstration of an algorithm suite supporting the automated extraction of intermixed natural (i.e., terrain, tree) objects and manmade (building, road, etc) objects using airborne or spaceborne LIDAR data and co-registered visible imagery.

Title:Innovative Surface Feature Extraction for Visualization using LIDAR Intensity and Co-registered Optical Data
Abstract:Pre-mission rehearsal using 3D, simulated fly throughs derived from remotely sensed data can signicantly enhance warfighter safety and efficiency. Because of its great potential for extracting the location, orientation, identification, and elevation profile of surface features, LIDAR (light ranging and detection) data provide an excellent information base for creating these simulated visualizations. The proposed work will demonstrate the feasibility of using both LIDAR signal return timing and, uniquely, signal intensity to extract surface features. The work will be based on the ELF (Extracting LIDAR Features) algorithms, currently under development by HyPerspectives scientists. The ELF algorithms employ intensity data for scene classification into vegetated and non-vegetated regions, then employ a unique search procedure for feature identification and characterization. The work also will show feasibilty of co-registering high resolution optical spectra to the LIDAR scenes. When used in conjunction with LIDAR, high resolution optical sensors (e.g., hyperspectral) can provide valuable and highly complementary data for surface feature identification and characterization. Phase I proof of concept efforts will employ single return LIDAR, seek to extract three terrain features (buildings, vegetated patches, non-vegetated ground), and require user input for selecting the original input grid search size. In the Phase I Option, we will automate the ELF algorithm search procedures and, like Phase I, benchmark performance for incorporating the extracted data into a visual database. Manual co-registration of optical data will be shown for a single scene in Phase I, then automated in Phase II.

Abstract:The United States Navy vision for Modeling and Simulation (M&S) includes making better analytical decisions, improving warfighting skills, and developing superior systems for maintaining the world's most powerful maritime forces for the joint force commanders. Over the past five years the potential for Light Detection and Ranging (LIDAR) data for the support Urban Warfare and various M&S initiatives has grown rapidly. LIDAR sensors capture the three-dimensional shape of the urban landscape at very high resolutions and accuracy. This resolution represents the character, or 3-D geometry, of the urban terrain, enabling precise line-of-sight, route analysis, cover and concealment, vulnerability assessment, and situational awareness to be performed. The data also provides the ability to extract objects from the scene such as individual buildings, trees, power lines, roads, and water. The Advanced LIDAR Exploitation System (ALES) program being conducted by the Joint Precision Strike Demonstration Project Office (JPSD-PO) will provide the M&S community with advanced database generation applications for the exploitation of LIDAR data.

Abstract:Diamond Visionics will develop new and automated processes for the creation of training simulator databases with scaleable fidelity and worldwide coverage. Diamond Visionics will provide tools that can automatically index large amounts of geo-specific imagery from various sources and provide a mechanism for incorporating this data into synthetic environments without manual intervention. We will provide innovative solutions based on our extensive background in spatial indexing and the run-time construction of synthetic environments using PC technology.

This system will greatly reduce the amount of effort required to improve the fidelity of visual databases. The Phase I Option effort will focus on implementing an integrated system prototype based on the algorithm that shows the best performance characteristics in the Phase I evaluation. Given tools that allow for the automatic and rapid incorporation of newly available imagery data into synthetic environments, the simulation community would be able to increase the effectiveness of simulator training. These tools would provide critical functions for both mission rehearsal and after-action review.

Title:Geoacoustic parameter estimation from bistatic and multistatic Fleet Air ASW acoustic reverberation data using Navy standard models, algorithms and databases
Abstract:The ability to estimate the geoacoustic properties of the ocean bottom from measured acoustic data has progressed rapidly with advances in non-linear inversion algorithms and with improvements in computing hardware. The current approaches based upon the inversion of measured transmission loss data are not readily compatible with existing Fleet Air ASW concept of operations. Reverberation data, both monostatic and bistatic, are much more available as part of a normal Fleet Air ASW mission. This proposal will extend the proven capability of the GAIT GS (Geoacoustic Inversion Toolkit - Global Search) software to handle the inversion of monostatic and bistatic reverberation data for local estimates of the ocean bottom's geoacoustic properties (LFBL and bottom scatter parameters) using current and proposed Navy standard models and algorithms. Initially ASPM, the core model of the ASPECT TDA, will be used for the reverberation inversion. It will be paired with GABIM (Geophysical Acoustic Bottom Interaction Model), developed by APL/UW who is teaming with PSI on the proposed tasks, as a replacement for the Lambert's Law bottom scatter kernel. The goal of the proposed tasks is to rapidly develop a fully automated inversion capability for both monostatic and bistatic reverberation data using proven models and algorithms.

Title:Littoral Environment Parameter Estimation from Bistatic and Multistatic Fleet Air Antisubmarine Warfare (ASW) Acoustic Reverberation Data
Abstract:Currently, collections of sonobuoy sources and receivers (sonobuoy fields) are being used to search for enemy submarines. These systems can potentially cover large search areas in relatively short times. However, like all sonar systems, their performance is very difficult to predict. This difficulty is not as much due to problems in understanding the physics of sound propagation, as it is to inadequate knowledge of important environmental parameters. Using a combination of existing tactical sonobuoys and emerging environmental sonobuoys, like the TAM buoy, sonar-important properties of the ocean could be estimated during a real mission. These measurements could then be used to get accurate indications of actual system performance and to potentially modify operating parameters of the sonar system to improve mission success. This proposal addresses what measurements to make, how to make them, and how to use them to improve system performance.

Title:Low Cost Three-Dimensional Reinforced Ceramic Matrix Composites (CMCs)
Abstract:The objective of this study is to define and demonstrate low-cost 3-D ceramic matrix composite (CMC) architectures and associated manufacturing processes for application to advanced military aircraft (such as the JSF) gas turbine engine components. Three-dimensional architectures offer the potential for increased durability by enhancing interlaminar and through-thickness mechanical properties. However, ineffective and inefficient processing issues need to be resolved. Overall the effort needs to properly consider and balance the effects of the three-dimensional architecture and its associated manufacturing processes, in terms of fiber integrity and adequate densification, to achieve affordability and durability benefits. In the initial phase, the feasibility of the low-cost three-dimensional architecture and manufacturing processes will be demonstrated via fabrication and testing of coupon specimens of selected candidate 3-D CMC's. Alpha STAR's commercially available GENOA software, a verified analytic/design tool, will be utilized to: accurately predict the 3-D CMC service lifetimes; predict their inspection, repair, and maintenance intervals, and optimize the 3-D architecture/manufacturing processes for durability, damage tolerance and low cost manufacturability, thus producing a better, low-cost 3-D CMC product. Successful demonstration/verification of a life prediction analytical methodology for low cost three-dimensional ceramic composites would reduce future certification costs of any advanced engine CMC structures.

Title:Affordable Low Dielectric Ceramic Composites with Improved Interlaminar Strength
Abstract:Hot structures fabricated from ceramic composite materials are an attractive design option for certain components of future aerospace vehicles and propulsion systems to reduce weight and increase survivability. Certain fabric-laminated ceramic composite components suffer from low interlaminar strength properties and are thus vulnerable to delamination when subjected to high thru-thickness thermal gradients and/or normal loads. This problem is of particular concern for pre-ceramic polymer-derived ceramic composite laminates that typically exhibit very low matrix dominated properties as compared to that produced by the chemical vapor infiltration (CVI) method. The objective of this proposed effort is to demonstrate the feasibility of producing an affordable fiber-reinforced ceramic-matrix composite material having low dielectric constant and significantly improved interlaminar properties. Low-cost 3D preforms using several commercially available low dielectric ceramic fiber types will be coated with a high-stability silicon-doped boron nitride (Si-BN) interphase and densified with high-strength/high-purity silicon nitride (Si3N4) produced by Hyper-Therm HTC's exclusive CVI process. Coupon specimens from the various composite systems produced will be evaluated to determine their respective in-plane and interlaminar mechanical properties, and electrical properties as a function of frequency. These results will be compared to a "baseline" fabric-laminated Si3N4 composite system to establish the overall viability of the proposed approach.

Title:Low Cost High Performance 3-D CMCs for Jet Engine Components
Abstract:In this Navy Phase I SBIR program, MATECH/GSM proposes to model and fabricate low-cost, high performance three-dimensionally woven fiber reinforced CMCs for jet engine applications. We will attempt to design a weave that mimics 8HSW within the in-plane and also contains warp stuffer yarns, thereby producing a Layer-to-Layer Angle Interlock Weave (LTLAIW). For this program, we propose to use both commercially available CG-Nicalon and our own SiNC structural ceramic fiber, currently under development with Navair support. SiNC matrix densification will be performed using the polymer-infiltration-pyrolysis (PIP) process, already optimized under a program supported by the National Science Foundation. The rational for ultimately replacing CG-Nicalon with MATECH SiNC ceramic fiber is higher thermo-mechanical properties combined with desirable electro-magnetic behavior required for this application. Additionally, having a fiber and matrix that are compositionally identical would eliminate any CTE mismatch, and thus help mitigate matrix cracking upon thermo-cycling.

Abstract:The fabrication of ceramic matrix composites is a multi-step process requiring careful monitoring and control at each step in the processing cycle. Consistent, high quality components can only be reliably reproduced if a firm foundation is provided by initially insuring the uniformity and consistency of the reinforcing yarns. Although considerable effort has been invested in developing NDE suitable for characterizing green as well as fully consolidated components, much less has been done to characterize the reinforcing yarns. In this Phase I program, we develop and implement in-line testing methods to characterized silicon carbide yarns. Methods are formulated to test both sized and un-sized yarns at the initial stages of the processing cycle. Experiments are performed relating various yarn defects to those found in the partially finished and finished composites. Integration of yarn testing methods into the normal manufacturing process will pay a large dividend in cost reduction, result in more consistent component performance (improved quality), and lead to improved process and product understanding.

Title:Innovative Quality Control Assessment Methods for Ceramic Matrix Composite (CMC) Components
Abstract:The proposed novel Nondestructive Evaluation (NDE) techniques will provide advanced characterization of Ceramic Matrix Composite (CMC) components to enhance manufacturing quality control, support component condition assessment and permit prediction of component performance. JENTEK has developed a family of electroquasistatic and magnetoquasistatic sensors and arrays that have successfully solved a wide range of previously intractable NDE problems. These sensors and arrays use model-based inversion algorithms to produce images of spatial variations of electromagnetic properties that have been correlated with many conditions of interest. NASA recently purchased a JENTEK system for detecting internal damage in the reinforced carbon-carbon material used on the leading edge of the shuttle wing. Also, JENTEK's Interdigitated Electrode Dielectrometer is being adapted for determination of porosity and incipient delamination of ceramic thermal barrier coatings on turbine engine components. In this proposed Phase I program, we will adapt JENTEK's electroquasistatic sensors with model-based inversion algorithms for characterization of CMCs for manufacturing quality control and in-service inspection. To address CMC manufacturing QC, we have assembled a team with CMC researchers (UDRI), fabricators (COI Ceramics) and an end user (Pratt & Whitney). In Phase II, we will develop a fieldable, prototype system for integration with the CMC manufacturing process.

Title:Defect and Damage Assessment Methodology for CMC Components
Abstract:Innovative research and development leading to a dual-use advanced technology product is proposed. The product is a methodology and associated software for defect and damage assessment of ceramic matrix composite (CMC) components. Once developed, the model would be used in conjunction with non-destructive inspection (NDI) methods to predict the effect of defects and damage on component life and residual strength. The primary focus is on CMCs for the JSF exhaust system components. However the methodology would be applicable to a much broader class of CMCs and components for military and commercial applications. An innovative Physics-Based mechanistic modeling approach is proposed. The approach includes direct consideration of relevant defect and damage mechanisms and environmental degradation. Phase I will involve characterization of the mechanistic model for CMC materials selected by Pratt & Whitney for exhaust nozzle application. The models will be validated against benchmark and sub-element test data. Predictions will be compared with experimental measurements to assess the modeling approach and feasibility for a comprehensive methodology development in Phase II. The proposed product is a comprehensive defect and damage assessment methodology and associate software for its implementation

Title:High-Temperature Amorphous Coating for CMCs for Protection against Hot Corrosion
Abstract:Ceramic matrix composites (CMCs) are being targeted for many military and commercial applications due to their light weight and high temperature stability. Their deployment is hampered by limited environmental durability. The Navy, under the JSF program, is evaluating a high performance CMC for an exhaust nozzle component. The CMC suffers from environmental degradation, primarily due to hot corrosion from salt ingestion. Severe thermal gradients imposed on the part, along with thermal cycling and fatigue effects, may cause matrix microcracking which exacerbates corrosion. Based on a new high-temperature stable amorphous coating material and low-cost and easy-to-apply solution-based process, ATFI proposes a study to solve this problem. The material's protection against molten salt and high temperature steam and compatibility with many metal and ceramic materials has been demonstrated over the temperature range of interest. Phase I will demonstrate its effectiveness by environmental exposure tests and high temperature anneals. If Phase I is successful, the technology can be transitioned rapidly due to the simplicity of the approach and the minimal capital equipment necessary. Phase II work will extend the concept to optimize coating formulation, application expertise, and demonstration of coating larger panels with the objective of transitioning the technology to the JSF program.

Abstract:Ceramic matrix composites have potential to meet many of the high temperature structural requirements for advanced military aircraft. One new material made from CG Nicalon fiber and polymer derived SiNC matrix may provide a preferred option for some applications. However, it has not been evaluated for hot corrosion for Navy applications. This program addresses the need to understand how it behaves in salt environments and proposes a Si3N4 coating approach to improve mechanical stability in hot corrosion environments.

Title:High Temperature Finishes/Sizings for Polyimide Matrix Composites
Abstract:New high temperature sizings are needed that are compatible with resin infusion processes to improve the properties and durability of carbon/polyimide composites. Compatibility with resin infusion processes includes compatibility with weaving and braiding operations and improved wetting with the infusing polyimide resin. Achieving these characteristics will result in reducing life cycle costs. The proposed Phase I program will explore two routes for improving handling and interfacial properties enhancement. A thermoplastic high temperature sizing, polyetherimide, known to improve the interface, will be optimized for use with AFR-PE-4 polyimide resin. In addition, an aqueous based reactive finish will be developed that is compatible with carbon fiber manufacturing. Similar solvent based finishes have been shown to greatly improve carbon/polyimide interfacial strength and thermo-oxidative stability. Development of an aqueous finish will greatly reduce costs while also improving health and safety. These sizings/finishes are expected to be compatible with weaving and braiding operations, will improve wetting during resin infusion processes, and improve the strength and durability of the resulting composites.

Title:High-Temperature Sizing for Carbon Fiber Reinforced Fluorinated Addition Polyimides
Abstract:The objective of this proposal is to develop a sizing system for carbon fiber that has the thermal stability to match or exceed that of the matrix resin and be chemically compatible with the fluorinated addition polyimides. More specifically, the sizing will have the same or similar composition to the matrix resin to promote miscibility and interdiffusion and endcapped with phenylethynyl functional group to allow the sizing and matrix to form covalent bonds. The sizing will be designed to be thermally stable during the full processing cycle, prevent fuzzing, and improve the processability of the fiber tow in the weaving and preform processing steps. In addition, the new sizing must meet all the criteria specified by the carbon fiber industry to be a commercially viable product. The sizing must be solvent free, nonflammable, contain no Hazardous Air Pollutants, and safe for worker exposure. The new sizing must be compatible with the manufacturing equipment and techniques employed at the plants. Major changes in processing and capital expenditure is unacceptable. To provide an advantage for our customers the sizing must ease fiber handling during manufacture and aid in secondary processes such as weaving.

Title:High-Temperature Adhesive Development
Abstract:The recent development of AFR-PE-4 polyimide composites has increased the high-temperature performance of large jet engine structures. To take full advantage of these "new" composite systems, high-temperature adhesives are needed to bond these components to other structures. Current F135 and F136 engine systems slated for the Joint Strike Fighter (JSF) require high-temperature adhesives that are formulated to provide service temperatures in excess of 316C (600F) for up to 1,000 hours of operation while retaining a 1,000 psi lap shear strength. Applications for "film" adhesives include honeycomb bonding and stiffening structures, while "paste" adhesives include dams, bonding of fasteners, and gap filler. The overall goal of the program is to formulate addition-cured polyimide resins and study the impact of chemical structure on high temperature properties, adhesion, and joint durability. Maverick will evaluate addition-cured polyimide resin chemistries with the goal of developing the "next-generation" high-temperature adhesive technology for AFR-PE-4 composite components. Maverick also plans to team with Akron Polymer Systems to formulate "reactive diluents," and to work with Adherent Technologies to develop "primer" technology which will "chemically couple" the substrate to the adhesive. This unique collaboration will be key towards the successful development of a high-temperature adhesive system.

Title:INNOVATIVE, THERMALLY STABLE, POLYIMIDE ADHESIVE TECHNOLOGY
Abstract:This Phase I SBIR program will develop a high temperature film adhesive with a service use temperature in excess of 316C that exhibits improved handling characteristics, higher toughness, and lower melt viscosity than the current commercially available state-of-the-art polyimide film adhesive, FM 680-1. Under the proposed research effort Performance Polymer Solutions Inc. will employ an innovative, novel approach to optimize the critical performance characteristics of an adhesive formulated resin system. In the Phase I effort, P2SI will incorporate an innovative inorganic reactive plasticizer to lower the melt viscosity, increase ductility and adhesion, and tailor the film to exhibit more epoxy-like handling characteristics, with volatile levels less than 5%. Ductility and performance will also be improved through incorporation of surface- functionalized fillers. In the Phase I Option, P2SI will utilize the Phase I technology to respond to engine manufacturer requests for a 600F cure temperature. These systems have enormous pay-off potential for both military and commercial applications.

Title:Threat Recognition and Early Warning Method
Abstract:The overall objective of this development effort will be to establish a "local" UAV surveillance platform and early warning system for a wide range of designated installations, bases and facilities. The system would provide around the clock ground surveillance and condition assessment, together with immediate real time response to any observed threat such as the launch of a mortar or missile. After the identification of a threat the system would provide threat recognition, and an automated warning with location and impact time information, provided in real time. This warning system linked directly to a facility would allow a few seconds of warning before impact. In addition, the same surveillance system would provide real-time information on the launch coordinates allowing an automated and rapid counterstrike to be made within seconds. The surveillance and warning system utilizes a range of sensors working to optimize the threat assessment, while maximizing the response time.

Title:Hyperspectral Classification for Muzzle Flash Recognition from the Silver Fox UAV
Abstract:One possible approach to discriminate between different projectiles and weapons is to analyze the muzzle flash spectra which is produced when they are fired. While the IR spectrum contains thermal information about the flame the UV portion of the spectrum contains information about the gas chemistry that is usually not affected by reflections - leading to a high signal to noise ratio. The proposed effort extends existing spectral analysis work in the visible and IR to observe the spectra in the UV. An extensive data base of different muzzle flashes and projectiles will be established from which key aspects of the spectra will be determined to enable future rapid assessment of the muzzle flash. Following the initial assessment of a wide range of spectra, a rapid computed tomography imaging spectrometer will be integrated onto the Silver Fox UAV for airborne reconnaissance and assessment of muzzle flashes. The outcome of the proposed effort will be a local airborne surveillance system that can provide rapid assessment of muzzle flashes, thereby discriminating between friend or foe.

Abstract:A program is proposed to perform mission-adaptable, covert surveillance in various contested environments to localize vehicles and weapons fire. Development of a covert, air-deployable (UAV & A/C) sensor system capable of operating in diverse environments and coherently overlapping multiple types of sensor data will significantly increase battlespace awareness, yielding early detection of threats and reduced casualties. To address the military's needs, a commandable multi-sensor cluster will be formed by deploying a gateway unit centrally located among a wireless network of various types of modular sensor nodes. Each cluster will be dispersed by a single airborne delivery vehicle. The cluster will utilize an array of microphones for all missions; other sensor technologies will be added to augment the detection, localization, and classification abilities of the acoustic array depending on the mission environment and suspected threats. A unique concept of modularity will be explored to achieve mission adaptability to a wide range of missions. An optical sensor module, for instance, can be interchanged to sense a completely different phenomenon, such as chemical/biological agents. The gateway logic will provide seamless integration of the sensor change into the overall system.

Abstract:The development effort for the Phase I program will entail a multi-step approach to developing a concept(s) for a low-cost fiber connector cleaning process and prove its feasibility.

In addition to this conceptual development effort, a systematic and objective test methodology will be established to quantitatively grade or determine the effectively of the cleaning process. This technique will be used to gather data during the cleaning experiments and will establish a common, unbiased means for evaluating cleaning effectively. All of the test data will be evaluated and estimates will be made as to the cleaning cost, apparatus size, and apparatus costs to bring the optimal cleaner to a productized state.

Abstract:Westover Scientific proposes to adapt our proven CleanBlast technology to a far simpler embodiment that would be ideal for field applicatons. The system would provide exceptional cleaning performance with little or no specialized training required. The cleaning process would be reduced to less than 3 seconds at a cost-per-clean of less than $0.20 (likely below $0.15). The device would be disposable, have a shelf life of over 18 months, and contain approximately 300 cleans per unit. Each device would include disposable tips for use with military connectors. We can provide these claims because the majority of the research has already been done to produce a like-product for the commercial market.

Title:Maintainer Head and Hearing Protection
Abstract:The U.S. Navy aircraft maintainer personnel need innovative, lightweight, head protection technologies that are compatible with recent advancements in single and double hearing protection devices. The current USN cranial system, worn by aircraft maintainers on the flight deck, was originally designed in the 1950's. During the past decades, jet aircraft engine noise levels have risen substantially. One result is that significant numbers of career Navy veterans have to apply for total hearing loss disability in their later years. The implication of exponential increases in yearly VA hearing loss claim amounts is that hearing protector attenuation values have not kept up with increases in jet engine sound levels. This Phase I program will initiate a formal process for design, development, and demonstration of new maintainer headgear that incorporates advancements in passive and active noise attenuation and communication technologies. Phase I goals will seek to develop advancements in numerous design metrics for the headgear that relate to: new anthropomorphic data for fit, user studies that define shape and comfort, easy integration of NVD and CBR equipment, improved maintainability and durability, product cost, and strict adherence to total daily exposure noise limits in noise fields up to 150 dB(A) SPL.

Title:Advanced Helmet for Maintainer Head and Hearing Protection
Abstract:Improved head and hearing protection is required for aircraft maintainers working on a carrier flight deck during launch and recovery operations. The current head protection is inadequate in many aspects including impact protection, hearing protection, cleaning, comfort, and compatibility with night vision goggles (NVGs) and with chemical biological and radiological (CBR) equipment. Creare proposes a new maintainer helmet that meets the needs of today's flight deck crew. The helmet will use advanced materials and innovative fabrication techniques in a design that is based on a recently completed program of intensive testing on the effectiveness of hearing protection components in extreme noise environments. To be effective, the design must resolve the many competing requirements for comfort, weight, and compatibility without reducing hearing protection performance. Creare has the expertise, understanding, test result database, and test techniques to meet this challenge. In Phase I, we plan to design and fabricate a prototype helmet and to measure its impact and hearing protection performance. We will identify approaches to improve comfort, cooling, maintainability and usability, and implement select features in the prototype. In Phase II, we will complete the helmet design, and we will build and test a production version of the helmet.

Title:Maintainer Head and Hearing Protection
Abstract:Head and hearing protection equipment used by Navy ground crew in the proximity of aircraft has remained fundamentally unchanged since the 1950s. New, inventive protective headgear technologies are sought to improve cranial impact protection, user comfort, and product maintenance as worn in areas of high-noise hazards and diverse weather and working conditions. Head injuries may occur due to hard surface and rotary blade impact. Proposed designs must be compatible with advanced hearing technology, NVD, and CBR equipment. Integrated electronics should be impervious to EMI, and no part of the assembly should become a FOD source. In Phase I of this project, DCCI will exploit the strengths of our recently improved headgear designs focusing on proposed ancillary items and their impact on such designs. New concepts will be developed integrating the supplementary items. Modern manufacturing processes and materials will broaden the scope of the new designs. During this period, weight, cost, logistic support, and environmental effects will be investigated. Advanced materials and resources will be sought, tested, and recommended. During Phase II, fully functioning prototypes will be developed, fabricated, laboratory tested, and placed into real-world environments to verify performance and to solicit end user feedback.

Abstract:Corrosion Health Monitoring Systems (HMS) and Prognostics are key to maintaining the performance and reliability of high value, critical structures. Joint Strike Fighter (JSF) Corrosion and Control Plan seeks to minimize life-cycle costs due to environmental degradation of nonmetallic materials and corrosion of metals by early detection, monitoring and prediction of corrosion using a HMS that meets critical size, weight, and power constraints, thereby requiring state-of-the-art in microsensor and electronic subsystem technologies.

During Phase I, the architectural strategy will be developed along with feasibility demonstration of a wireless corrosion sensor system. Data collection and software protocols issues for data downloading will additionally be addressed during this effort.

Title:Wireless Sensors with Advanced Detection and Prognostic Capabilities for Corrosion Health Management
Abstract:Thin film galvanic sensors provide feedback on corrisivity via current and charge accumulation. They do not provide direct feedback on material loss. By combining these sensors with guided wave corrosion sensors, galvanic activity can be directly related to material loss via guided wave data. As a result, corrosivity can be directly related to corrosion. Galvanic thin film sensors have there limitations. For instance, they detect local corrosion activity. While one area may be subject to significant corrosion activity, an adjacent area may experience significantly less activity. This type of false alarm my call for unnecessary maintenance action. As a result, the following question arises. How do maintenance personnel perform large area corrosion health monitoring using galvanic sensors with minimal false alarms. The answer is by combining thin film galvanic sensors with guided wave corrosion sensors. When considerable localized corrosivity occurs, the galvanic sensors trigger the guided wave sensor to take data on the entire structure. By using the galvanic sensors to trigger the guided wave sensor, the extent of corrosion in terms of both area and depth can be obtained.

Abstract:Detecting and monitoring galvanic activity/corrosivity and quantifying the resulting corrosion damage are key capabilities for corrosion health management. Advanced sensor constructs and sensor suites are needed that can work together to monitor local environment conditions and actual material condition, especially in complex structures and components that include multiple material types. JENTEK has developed a family of electroquasistatic and magnetoquasistatic sensors that utilize model based inversion algorithms to determine absolute values of multiple unknown material properties that correlate with many conditions of interest. These thin film sensors are extremely reliable and repeatable and their small size and light weight permit them to be permanently mounted in aerospace structures. In this proposed Phase I program, JENTEK will evaluate innovative applications of electric and magnetic field sensing approaches to provide in-situ monitoring of electrochemical/galvanic activity as well as condition assessment of structural and protective materials. Sensor constructs will be explored that embody winding and sensor geometries that lend themselves to physical modeling, permitting accurate response prediction and reliable monitoring of relevant conditions over time. In Phase II, we plan to implement an integrated suite of sensors for JSF component testing which may include rapid remaining useful life prediction and wireless communication capability.

Title:Enhanced Rotorcraft Aerodynamic Modules to Support Flight Testing
Abstract:Progress has been made in developing high fidelity rotorcraft simulation models in order to adequately predict rotorcraft performance, stability, and loads in support of design, operation, and flight testing. Limitations, however, exist in several essential aspects of modeling rotor aerodynamics including blade stall, rotor tip effects, rotor downwash, rotor/airframe interference, and rotor aeroelastic interaction. We propose to: (1) enhance blade dynamic stall modeling to improve the prediction of 3D stall delay and accuracy of blade drag and pitch moment; (2) enhance blade tip modeling to consider the 3D blade tip effect; (3) enhance high rate of descent modeling by including the effects of unsteady variation of the vortex ring state; (4) enhance rotor wake and aerodynamic interference modeling by allowing for the effects of high blade twist and inclusion of fuselage interference on the rotor; (5) enhance rotor aeroelastic modeling by developing a coupled airframe/rotor and coupled FLIGHTLAB/CFD solution for the aeroelastic blade loads calculation.

Title:Advanced Rotorcraft Aerodynamic Modules for Flight Testing Support, Simulation and Analysis
Abstract:Accurate performance prediction is crucial to the simulation, analysis and flight testing support of rotorcraft. In this regard, current analysis tools inadequately model key phenomena like blade dynamic stall, rotor tip loads, and rotor downwash because of their failure to predict the true unsteady three-dimensional nature of the aerodynamic environment near the rotor. Continuum Dynamics, Inc. (CDI) has recently developed breakthrough technologies in real-time lifting panel and free-vortex wake modeling that will allow us to address these issues with unprecedented fidelity at low CPU cost. A new fast lifting surface blade aerodynamics module is proposed building on CDI's state-of-the-art vortex lattice and fast panel solution technology that will, for the first time, allow accurate modeling of three-dimensional rotor tip effects for arbitrarily-shaped rotors in general maneuvering flight. Coupling this new technology with CDI's extensively validated, full-span free-vortex wake model, will provide unparalleled predictions of unsteady loading and details of the rotor flow field for general flight conditions including high rate of descent. Finally, a new efficient, accurate blade dynamic stall model is proposed utilizing an enhanced combination of fast panel/vortex algorithms, rounding out the ability of the solution techniques to model all the crucial aerodynamic phenomena identified in the solicitation.

Abstract:Prognostics and Health Management (PHM) for the Joint Strike Fighter (JSF) is envisioned as a comprehensive system for detecting and isolating failures, recommending condition-based maintenance (CBM), and estimating the remaining useful life (RUL) of critical components. Barron Associates, Inc.

In Phase I, BAI will evaluate the performance of these algorithms operating in a realistic JSF simulation provided by LM Aero.

Title:Failure Precursors and Anomaly Detection in Complex Electrical Systems Using Symbolic Dynamics
Abstract:Failures in a plant's electrical components are a major source of performance degradation and plant unavailability. In order to detect and monitor failure precursors and anomalies early in electrical systems, we propose to develop signal processing capabilities that can detect and map patterns in already existing, available signals to an anomaly measure. Toward this end Professor Asok Ray at Penn State University has pioneered an elaborate mathematical theory of "language measure" based on real analysis, finite state automaton, symbolic dynamics and information theory. Application of this theory for anomaly detection results in a robust statistical pattern recognition technique. This technique is superior to conventional pattern recognition techniques such as neural networks and principal component analysis for anomaly detection because it exploits a common physical fact underling most anomalies which conventional techniques do not. This superiority has recently been demonstrated on electrical circuits, lasers and in mechanical components. The objectives of the research proposed by Intelligent Automation Incorporated (IAI) and its subcontractor are: (i) to develop real-time anomaly sensing and monitoring systems for early detection of faults in avionic electrical systems; and (ii) to experimentally validate the proposed concept on an active nonlinear electrical circuit.

Title:Integrated Prognostics for Missile Electronics
Abstract:Ridgetop will work with Raytheon to apply Electronic Prognostics to critical electronic systems in advanced missile systems. The focus will be on latent defects that escape conventional functional test suites. This investigation involves identification of critical components from failure rate analysis, extracting and measuring precursors to failure, and collecting and processing the results into a single composite Electronic Prognostics Indicator. For this SBIR, Ridgetop will create a test board design that can be used for accelerated aging and analysis of induced failures. Additional prognostics will be added to Ridgetop's Prognostic library such as FPGA packaging faults (solder failures) and also connector problems found in missile systems. The test board will be overstressed and cycled in a controlled manner to reveal defects at Raytheon's facilities in Tucson. The resulting signatures will be analyzed and processed to yield the composite latent defect metric.

Abstract:The program will develop the necessary monitoring techniques and modeling tools needed to assess the state-of-charge and health of nickel cadmium batteries. The developed system will be designed and implemented into an advanced prognostic and health maintenance system that will actively determine when service of critical components will be needed. The developed models will be based on physical processes that occur during operation of the battery. Existing models of nickel cadmium battery performance will be augmented to include the fade mechanisms of interest. Monitoring techniques will be integrated with the developed models to provide improved health and state of charge predictions.

Title:State of Health Indication Improvement of the Nickel-Cadmium Battery
Abstract:We propose in conjunction with Dr. M.A. Alim of Alabama A&M University to measure through small signal ac voltage injection and frequency response analysis the internal complex impedance of the target battery over various charge/discharge rates, temperature, and number of cycles. Correlation will be observed between the impedance variations and state of charge and state of health of the target battery. A simplified algorithm will be developed that will provide a high level of confidence and accuracy with minimal impact on battery operation and load. Hardware modifications will be proposed to provide small signal ac injection and response measurements for the target battery.

Title:Embedded Wiring Diagnostic Technology for Aircraft
Abstract:Innovative Dynamics Inc. proposes to develop a Wire Health Management System (WHMS) that provides prognostic and diagnostic tools for detecting, identifying, and locating wire faults. The expected result for the Navy is substantially reduced maintenance costs and down time of aging aircraft. The proposed WHMS incorporates multiple sensors into "smart" clamps to monitor wire chafing and arcing events that account for more than 50% of wire fault incidents. The sensors can also be used to detect loose connections, temperature increases indicative of fire or other wire anomalies, fluid contamination, and connector cross-mating to cover 80 - 90% of all wire incidents. Smart components also provide the capability to mitigate unwanted wiring vibration through active noise cancellation techniques, and thus extending life of key wiring components. All can be configured to be non-intrusive fault indicators such that nothing needs to be disconnected or dismantled to conduct the inspection. The system operates continuously in-flight so that mystifying intermittent conditions can be spotted as they happen. The system can also be used for ground inspections as well. IDI proposes to develop a comprehensive implementation plan on new and legacy aircraft covering installation through end use.

Title:Embedded Wiring Diagnostic Technology for Aircraft
Abstract:The objective of this proposal is to develop and integrate an Embedded Smart Connector (SC) with wire diagnostic technology that can be temporarily or permanently installed into the aircraft wiring system to report the health of the vehicle wiring. This smart connector can be used to detect and locate in-flight anomalies. It can also be used to collect early in-flight data to illuminate the deterioration of wiring and provide information towards the goal of prognosis of wiring faults. The sensor technology that will be used is spread spectrum time domain reflectometry (SSTDR), which has been demonstrated for accurate fault location (to within a few inches) on live wires carrying DC, AC power or digital data signals. SSTDR technology has proven to be highly accurate despite noise caused by the external environment including the switching of motors, lights, etc. and related noise associated with realistic loads.

Title:Distributed Monitoring of Electrical Wiring
Abstract:Electrical wiring interconnect system (EWIS) damage due to mechanical, thermal, electrical, and chemical mechanisms can result in loss of critical systems, smoke and fire, and lead to catastrophic equipment failure. Aircraft wiring is the subject of intensive research efforts to predict and prevent the failure of electrical systems in existing and future military and commercial aircraft. To address this critical need, Luna Innovations proposes to use distributed optical fiber sensors to monitor and locate wiring damage or conditions that may lead to EWIS damage. The sensing technique is capable of temporal and spatial measurement of wiring system condition. The system is sensitive to processes that degrade the EWIS in different zones of the aircraft structure and damage events associated with maintenance activities or other sources. Both transient conditions and permanent changes in state are detected. Damage modes and conditions can be sensed without imparting damage to the optical fiber sensing element. Additionally, the EWIS condition can be compared to any previous condition. This allows aircraft operators to locate areas of significant change in the health of the EWIS that require inspection. This cumulative data is also valuable for developing zonal analysis of aging processes for use in prognostic EWIS modeling.

Title:Erosion Resistant Coatings for Shaft-Driven Compressor (SDC) Impellers
Abstract:The purpose of this proposal is to demonstrate the effectiveness of erosion resistant coatings for extending the life of shaft-driven compressor (SDC) impellers on the V-22 Osprey. Shaft-driven compressors are used on many aircraft to provide service to on-board inert/oxygen gas separators and environmental control systems, as well as other functions. The impellers in SDCs typically operated at from 87,000 to 100,000 revolutions per minute, at temperatures ranging from 125 F to 600 F. Aircraft that operate in sandy or dusty landing zones, or during dust and sand storms, have experienced rapid erosion of the SDC impeller leading to loss of critical functions and potentially catastrophic system failures. The goal of the project is to extend the impeller life by at least a factor of ten.

Title:Cathodic Arc Synthesis of Sand-Erosion Resistant, Boride Coatings for Titanium Alloy Compressor Impeller Blades
Abstract:In environments where the atmosphere can contain a high concentration of sand, the erosion of jet engine turbine blades becomes a dominant mechanism for reduced aircraft engine lifetime. NAVAIR is seeking a coating solution that will dramatically decrease this sand erosion wear mechanism, especially for titanium alloy impeller blades in the compressor side of its aircraft engines. HY-Tech is offering to apply its surface treatment technology, which is uniquely able to apply a super-high hardness (3 times that of sand), yet low modulus (i.e. elastic, providing good impact resistance), boron-rich thin film coating, with excellent adhesion to titanium alloys (as well as steels). The adhesion is achieved without the need for a bond coating, by using the energetic ions of boron involved in this process to form a reacted diffusion layer. Boron forms strongly bonded compounds with titanium; the compounds themselves are also hard and erosion resistant. The Phase I project will seek to demonstrate this solution by means of sand erosion testing of boron-coated flat-samples at a qualified facility and to determine the relationship of sand erosion performance to the depth and quality of the reacted layer.

Title:Terahertz Imaging System for Automatic NDE and Detection of Foreign Objects in Composite Components
Abstract:This proposal describes an approach for the use of terahertz band radiation, or T-rays, for nondestructive evaluation (NDE) and detection of foreign objects in manually constructed composites. Contaminates introduced during the fabrication phase of composite airframe parts contribute to high rejection rates. A method of identifying foreign objects embedded in a lay-up before curing of the part, and allowing their removal, would reduce the financial penalties associated with manufacturing composites. T-rays have many advantages over traditional NDE techniques, including being non-ionizing radiation and the ability to "see-through" many opaque materials. Due to the unique approach to constructing terahertz images, new processing techniques are applied in order to identify and extract information from the images relevant to detecting foreign objects. A multi-resolution decomposition is coupled with Bayesian classifier to learn the characteristics of foreign objects embedded within various composite types and allow automatic detection.

Title:Detection of foreign materials in uncured hand layup composites
Abstract:Fiber-reinforced polymer prepreg materials are supplied in the form of tape, tow and fabric. During the cutting and lay-up processes, some of the backing material (release film) remains on the prepreg. Composite parts manufactured using such prepreg materials can fail since the backing material prevents a good bond between individual plies. Menon and Associates proposes to demonstrate a RF-based profiler system to detect the backing material. The principle is based on exciting specific nuclei inside composite materials. These nuclei are found within the contaminants and are very different from those found in the fiber and matrix. The profiling process allows individual layers within a structure to be inspected rapidly while the various plies are being laid down in the mold. Contaminants such as aluminum, paper, plastic, Teflon, oil and moisture can be detected and identified. In addition to profiling, the system will allow detailed analysis of heat damage at any depth. In Phase I we propose to demonstrate feasibility of the profiling system. We will prove that contaminants can be detected inside uncured composites laid on a steel mold. In Phase II we will build and demonstrate a prototype hand held system for detecting contaminants in uncured composites.

Title:Advanced Multi-Band Electronic Surveillance Measure (ESM) Antenna
Abstract:The objective of the Phase 1 and 2 SBIR Program, Topic N04-263, "Advanced Multi-Band Electronic Surveillance Measure (ESM) Antenna," is to develop a multi-band, lightweight ESM antenna, includes communications intelligence (COMINT), electronic intelligence (ELINT) and communications systems and data links, and is capable of being installed on multiple, unmanned air vehicle (UAV) platforms. The antenna may be installed at multiple locations on the air vehicle, such that they can be coherently processed to create an interferometer to measure angle of arrival of emitters. Revolutionary antenna technologies are sought that will be lightweight, provide a wide area RF coverage, and be capable of interfacing with existing and planned UAV ECM/Electronic Intelligence (ELINT) systems. The real challenge is to preserve the gain and coverage characteristics of multiple antennas in a single integrated package. It has been suggested that the full frequency coverage desired is 100 MHz to 18 GHz with an objective of 20 MHz to 40 GHz. Further it would be desirable to be able to transmit over the 20 MHz to 2 GHz frequency range. The system should have a higher gain as the angle of reception approaches the horizon, a 1/R space loss function. The antenna shall be circularly polarized, thus being able to operate with vertically and horizontally polarized signals also. A single connector shall be used for the full frequency coverage. The VSWR shall not exceed 2:1 over the required frequency band. The primary requirements driven by use on UAV's are: form factor, (shape, size, depth), weight, aerodynamic drag, cost, structural capabilities, and RF performance.

Title:Advanced Multi-Band Electronic Surveillance Measure (ESM) Antenna
Abstract:The Spectra-GTRI team proposes an innovative approach to optimizing weight on UAVs by integrating the antenna systems directly into the UAV wing or fuselage mechanical structure. By carving slot antennas of various sizes out of the wing structure, an array of bandwidths can be accommodated. Employing pairs or sets of antennas across the wingspan enables the use of direction finding to determine RF emission source bearing. The dual use of a structural feature as a sensor offers an innovative approach to minimizing weight on ESM platforms. Employing GTRI's advances in fragmented aperture and MetaMaterials research, a wing, tail, or fuselage of a UAV can be utilized as a radiating antenna without loss of structural integrity.

Title:Tools for Software Architecture Visualization
Abstract:The problem of supporting large mixed-language software systems is of great importance to the Navy and beyond. Often the only reliable source of information about their architecture is the source code itself. Having a reliable way to automatically create visualizations of the architecture is key to understanding the system, and for planning changes. We propose the development of a set of tools for automatically extracting UML design diagrams directly from the source code. The techniques will mostly be based on a static view of how objects in the code interrelate, and will allow the extraction of the class diagram, the object diagram, the interaction diagram, and the state diagram. We also propose cluster and concept analysis techniques for helping users understand the structure of less well-structured programs. These tools will be based on our existing static analysis technology, which is already highly developed for C and C++, and for which a version for Ada 95 is currently under development. We additionally propose an option to study using techniques to extract dynamic visualizations. The tool will produce output in the form of XML objects in a standard format that can imported into existing UML design tools.

Title:Automated Software Architecture Analysis and Visualization Advanced of Large, Mixed-Language Systems
Abstract:Large, complex software systems are difficult to maintain, modify, and enhance. Information regarding the overall system architecture and individual component design is often sparse, and usually informal. In order to effectively address legacy system maintenance and evolution, we must provide facilities to recognize and represent the information abstractions which exist throughout a software system, at every design layer. Our objective is to investigate the feasibility of leveraging a combination of: a) language-neutral models, b) source code analysis techniques, and c) user interaction with graphical representations, to extract and maintain higher-level software knowledge. Our fundamental innovation is this combination of analysis results -- to propose and highlight potential abstractions, and cooperative user interaction -- to accept, elaborate, or modify them, all supported by an underlying suite of extensible source code analysis and exploration tools.

Title:Miniature GPS Antenna System
Abstract:Current anti Jam GPS antennas are approximately 14" in diameter making them too large for several platforms of interest such as unmanned aerial vehicles, missiles and fighter aircrafts. A modified version of this antenna array is significantly smaller in size (seven inch diameter) but incorporates only 4 antenna elements, thus, limiting its nulling capabilities under severe jamming conditions. To alleviate these limitations, Applied EM is proposing a miniature GPS antenna that would allow for anti-jamming capability (with 5 to 7 elements) to acquire accurate PVT (Position, Velocity and Time) in a hostile RFI (Radio Frequency Interference) environment. This will improve GPS reliability for situation awareness in battlefield scenarios and will further make GPS a viable solution for precision approach and landing. A second focus of our proposal is to enhance the antenna electronics using -time adaptive processing (STAP) or space-frequency adaptive processing (SFAP) with optimum performance.

Title:Miniature GPS Antenna System
Abstract:MetaMaterials with new advancements such as fragmented aperture antenna arrays may offer additional significant advantages in the drive to provide reduced size, high efficiency controlled radiation pattern antennas (CRPAs). The Spectra Research-Georgia Tech Research Institute (GTRI) team proposes to apply fragmented aperture and MetaMaterials technology to develop a lightweight small antenna solution capable of receiving both the L1 and L2 GPS bands necessary for military applications. DARPA-sponsored GTRI programs in MetaMaterials have lead to the development of materials directly applicable to reducing patch antenna size while other DARPA-sponsored initiatives fragmented aperture technology has resulted in a GTRI toolset readily equipped to allow these antennas to receive both GPS bands. This combination can be manufactured using planar circuit board fabrication and solves the anti-jam problem without the need for esoteric textured LTCC materials. Furthermore, these antennas are made with very flexible dielectrics presenting the potential for future application to conformal surfaces.
