  • A new method of SAR jamming is proposed: the 2-D cosinusoidal phase modulation repeater jamming. This jamming method makes SAR echo extend both in range frequency domain and azimuth?Doppler domain via 2-D cosinusoidal phase modulation, and achieves the effect of multi-false targets. The research in principle shows: this jamming takes advantages of both efficient energy usage like 2-D coherent jamming and well suppression as non-coherent jamming. It can form tight flat shape false targets or grid shape false targets to protect distributed important targets, according to well configured jamming modulation parameters. Its validities are proved by the simulation and real data simulation.
