A Partitioned Deceptive Jamming Method against TOPSAR

A deceptive jamming method against terrain observation by progressive scans synthetic aperture radar (TOPSAR) that considers the effect of the changing relative position between a jammer and a TOPSAR platform is presented. The method can generate flexible false targets with varying Doppler centroids. The jamming problem is decomposed into simpler sub-problems of the same type, according to the relative position between the jammer and the satellite. The partial deceptive jamming modulation function can be pre-generated before the radar parameter reconnaissance. The partitioned scheme produces multiple deceptive jamming batches in parallel on the TOPSAR image to protect large regions of interest (ROIs).
