Abstract

In an effort to image and geolocate moving targets using transmitters of opportunity (Passive radar), three situations - Monostatic LFM, bistatic LFM and bistatic OFDM are considered. Here OFDM waveform plays the role of an ideal LFM waveform that has superior resolution. In the case of moving targets, the shift in their imaged locations by virtue of their motion are accounted for in terms of target radial velocity. This allows us to correctly geolocate the moving targets both in the monostatic and bistatic cases knowing the target signature location along with its radial velocity. The results are verified using realistic multiple moving targets in moderate clutter to account for various moving target scenarios.
