Systran Federal Corp. (SFC) and our research partner propose to develop an airborne parasitic bistatic radar system for the purpose of target detection with a passive radar receiver. Passive bistatic radar systems have existed for some time, but for this project, we propose to locate the system s post-processing on a high-end PC. In Phase I we will demonstrate the feasibility of a complete PC-based passive bistatic surveillance system. This implementation will be built upon a very large baseline of technology already funded by the Government and by a related IR&D demonstration project using linear FM waveforms, as well as continuous waveforms (CW), to generate reconnaissance bistatic parasitic intelligence products. In Phase II we will develop a PC-based sensor test-bed suitable for use on a manned aircraft. In Phase III we will fabricate a complete and robust wide-band PC-based passive bistatic surveillance system suitable for use on both military manned and unmanned aircraft. The overall goal of this effort is to design a systematic approach to transition the current post-flight processing bistatic SAR/SMTI baseline into a disruptive technology for use by our armed forces.BENEFITS: The benefits of this new technology are many. Of significant note is the ability to couple the benefits of parasitic, bistatic radar with the benefits of a small, inexpensive, COTS processing platform. Bistatic radar receivers are passive and thus undetectable. Also, the techniques used to reduce monostatic radar cross section often do not apply to bistatic systems. Therefore, this type of system is useful in both stealth and counter-stealth applications. Placing it on a PC-based, COTS platform will reduce cost and size and make it even more attractive as a radar solution.
