Abstract:

Considering the motion error of the enemy SAR, this paper proposes a novel realtime approach of deception-jamming. Via quick algorithm, this method pretreats the deception picture first, and then does the convolution operation with the received signal and transmits the signal. In this way, the distance between SAR platform and jamming equipment can be simulated effectively, and the echos contain the motion information. After motion compensation and SAR imaging operation, a more lifelike image can be obtained. This method proposes a quick algorithm of deceptive scene signal generation based on two-step processing, which ensures realtime generation of the signal. Simulation and experimental data have proved the validity of the approach.

Key words: SAR Imaging, deception-jamming, motion compensation, quick algorithm
