28GHz-43GHz Nadir/Near-Nadir (~70-90 degrees wrt horizontal) Low Probability of Intercept Radio Frequency Direction Finding/GeoLocation Capability Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-118 Topic Title: 28GHz-43GHz Nadir/Near-Nadir (~70-90 degrees wrt horizontal) Low Probability of Intercept Radio Frequency Direction Finding/GeoLocation Capability Proposal No.: N102-118-0991 Firm: Syntonics LLC 9160 Red Branch Road Columbia, Maryland 21045-2002 Contact: Steven Gemeny Phone: (410) 884-0500 Web Site: www.SyntonicsCorp.com Abstract: Syntonics will demonstrate the feasibility of a direction finding / geolocation capability based on the Team's pixel-addressable reconfigurable conformal antenna (PARCA) Software-Defined AntennaT technology. With prior DoD SBIR funding from the Missile Defense Agency, the Navy, and the Air Force, the Team of Syntonics LLC and the ElectroScience Laboratory of The Ohio State University (ESL/OSU) have already made significant progress towards realizing the PARCA concept of Software Defined Antennas. PARCA is a conformal phased array technology that operates under software control to be pointing-agile, frequency-agile, polarization-agile, low profile, and affordable in production. Benefits: PARCA is a software defined antenna technology that replaces numerous, narrow band, unique function antennas with a single, reconfigurable, multifunction aperture. PARCA antennas can use variable, software defined gains and beamwidths (search/track mode switching) as the LPI target location become better resolved. PARCA antenna arrays employ beam steering through feed network time delay allowing PARCA antennas to locate RF sources with a single antenna installation using closed loop steering.PARCA apertures are comprised of an array of small square tiles stacked to provide extreme flexibility in creating conformal apertures of varied shape. PARCA can satisfy a wide variety of SIGINT/ISR deployment applications. SIGINT/ISR applications will benefit by having higher gain, frequency-agile antennas with better beam direction control housed in a single multifunction aperture. Return
