The end goal for this research is the delivery of a software application capable of detecting and characterizing non-cooperative hidden nodes (NHN) which can be installed and operated on military and commercial communications equipment. The research effort will define and study the threat, define and evaluate detection and characterization algorithms, and estimate their performance through a para ...

Our system uses the Cognitive Radio itself as a sensor to form a Cognitive Network that performs non-cooperative hidden node detection and characterization. PHY layer information is collected in order to perform Specific Emitter Identification (SEI), Geolocation, and Network Topology Discovery, making it possible to detect a hidden node and hidden node candidates. Data-link layer (DLL) informati ...

During the Phase I Program, Aurora Flight Sciences and the University of South Carolina will demonstrate the feasibility of co-curing an integrated antenna assembly within carbon composite structures. As part of this program, a candidate platform will be selected from one of Aurora"s current UASs which will serve as the baseline for the program and provide a commercialization path for conformal a ...

Combined with the demands for UASs is the increasing demand for additional electronic systems, payload carrying capacity, and antennas that are required for each electronic/communication system on the platforms. Broadband conformal antennas offer unique solutions to the strict size weight and power requirements for sensors deployed on UAS. Multi-functional conformal antennas can also address the ...

Up to 40% of all U.S. and coalition deaths in both Iraq and Afghanistan have been due to improvised explosive devices (IEDs). In addition, the Department of Homeland Security reports that more than 600 IED incidents occur worldwide each month outside of these regions, including within the U.S. While IED detection technologies continue to improve, insurgents and others who place IEDs are highly ada ...

Detection, localization, and tracking in over the horizon radar (OTHR) systems is a challenging problem due to the existence of multiple ray mode propagation paths between the transmitter, target, and receiver. Traditional OTHR multi-target tracking techniques use three isolated processes: slant azimuth/range/Doppler estimation (detection), followed by association of detections to targets and mod ...

Propagation Research Associates, Inc., (PRA) proposes to develop a real-time error correction processor using multimode tracking for over the horizon radar. In particular, PRA will leverage its extensive experience in propagation effects and tracking algorithms coupled with target selectivity algorithms to develop a dynamic real-time mode linking process for over the horizon radar using aircraft b ...

ABSTRACT: The Global Navigation Satellite System (GNSS) includes modernized global positioning system, the European Galileo, Russian Glonass, and the Chinese Beidou systems. Many next-generation receivers will include additional GNSS satellite signals to improve accuracy and satellite availability. The GNSS frequencies span from 1164 MHz to 1300 MHz and also 1559 MHz to 1611 MHz. The Right Hand C ...

ABSTRACT: Modern turbine engines are advancing with remarkable progress in the development of increasing power, decreasing fuel consumption, and enhanced controls allowing for prognostic estimation of health. Even so, there are areas of these engines which can be dramatically improved given suitable enabling technology. One such area is in the adaptive adjustment of blade clearances, which can ...

ABSTRACT: Turbine engine performance, efficiency, and reliability can be greatly improved if additional and evolving instrumentation can be added for input to the FADEC and PHM systems. As this additional instrumentation becomes a larger percentage of the engine"s total life cycle cost; the need to reduce maintenance and installation overhead for new instrumentation becomes increasingly importan ...
