Abstract

Radio frequency (RF) spectrum crowding has resulted in the need for interoperability between radar and communications systems. Passive radar has been investigated as a means to exploit the proliferation of RF systems to perform functions such as detection and tracking of moving targets. Passive multistatic radar may alleviate spectral fratricide by replacing some active monostatic radar systems. Part 1 of this study presents results from a passive multistatic radar experiment that exploits worldwide interoperability for microwave access (WiMAX) communications waveforms to detect moving targets. Signal processing strategies for high-duty cycle, low pulse repetition frequency (PRF) waveforms are discussed and validated on experimental data. Part 2 of this article attempts to address the outstanding research issue of combining data from multistatic radar systems to increase performance.
