Abstract:

Aiming at the principle of the SAR-GMTI, a new passive SAR-GMTI barrage jamming approach based on the rotating angular reflector is proposed. The method makes use of micro-Doppler modulation induced by the rotating angular reflector form jamming strips along the azimuth. After the clutter is restrained, the jamming strip makes the motion target checking false so that it is impossible to accomplish the orientation and estimation of parameters. Theory analysis and simulation experiment validate the SAR-GMTI jamming method.
