Abstract

Modern communication systems provide myriad opportunities for passive radar applications. Research is introduced here on the passive use of worldwide inoperability for microwave access (WiMAX) orthogonal frequency division multiplexing (OFDM) waveforms for synthetic aperture radar (SAR) ground imaging. The anatomy of the waveform is presented followed by a brief bistatic ambiguity function analysis. The monostatic and bistatic models for OFDM range compression are derived and validated with experimental data. We conclude with SAR imaging results and a discussion on future research.
