Single pulse imaging

A novel radar receiver processing technique is presented which utilizes the Doppler phase shift resulting from high-speed targets to produce a range/Doppler image from the return signal of a single radar pulse. Denoted as Single Pulse Imaging (SPI), this technique utilizes the general framework of the Multistatic Adaptive Pulse Compression (MAPC) algorithm and applies it to monostatic radar in which Doppler-shifted realizations of the transmitted waveform are treated as different waveforms that have illuminated different range profiles thereby resulting in the superposition of different signals at the receiver. The joint separation and pulse compression of the set of received signals produces a range/Doppler image whereby, given sufficient disparity in radial velocity (and thus sufficient Doppler phase-shift diversity), individual scatterers within the same range cell can be discerned.
