Clutter cancellation in passive radar using batch-based CLEAN technique

Abstract Passive radar (PR) systems need to detect the presence of a target response, which is many orders magnitude weaker than clutter (direct signal and multipath). Indeed, cancellation key stage within PR processing scheme. One most effective techniques in this field using CLEAN approach. In paper, batch-based technique based on GMP FFT has been proposed, can speed up computational have better gain. Furthermore, segmenting operation be applied obtained over long time. It helpful enhance temporal or spatial efficiency overcome effect time-varying clutter. Experiment results with simulated real passive data verify effectiveness proposed algorithm.
