Low-cost chaotic radar design *a a b b G. Martin Hall , E. Jeff Holder , Seth D. Cohen , Daniel J. Gauthier aPropagation Research Associates, Inc., Suite 100, 1275 Kennestone Cir. Marietta GA, USA 32958; bDepartment of Physics, Duke University, Durham, North Carolina, USA 27708 ABSTRACT An approach for creating a low-cost Chaos Pulsed-Doppler Radar is presented. The objective of this effort is to develop a practical realization of a Chaotic Radar with performance advantages over other approaches. Many groups[1], [2], [3] have proposed that Chaotic Waveforms are an effective radar signal generator due to: the relatively low cost of producing complex wideband waveforms and the difficulty in detecting and spoofing inherently complex modulations. PRA and Duke University report on the development of a radar design that uses a novel high-speed chaotic waveform generator. Preliminary experimental results are presented that characterize the performance of a chaotic waveform generator. In addition, the radar architecture will be proposed, realistic radar design criterion will be set forth, and simulations of a complete radar will be used to compare the chaotic radar to more traditional radar approaches.
