Abstract

To solve the problem that how to product multi-high-vivid false moving targets for SAR-GMTI, a new jamming method was proposed. The method begins with motion modulation and cosinusoidal phase-modulation on intercepted SAR signals, intermittently sample, and then transmit them. The jamming signal after SAR imaging provides the jamming effect of reticular multi false moving targets. After GMTI processing, the amplitudes of false targets have enhanced and weakened areas under the influence of suppression and cancellation for multi-channel GMTI. Simulation results verify the analyses and its jamming effectiveness for SAR-GMTI.

Key words： SAR-GMTI; motion modulated; cosinusoidal phase-modulated; intermittent sampling; deceptive jamming
