Research on SAR Jamming Technique Based on Man-made Map

Based on the scattering characteristics of targets, aimed at the different radar parameters, in this paper a method is presented to transfer the position of every point in the desired man-made maps into the corresponding point in the time-domain, and then store them into the DRFM in advance. When jamming is needed, the data in DRFM is convoluted with the received radar signals, and then the result signal is retransmitted. After radar processing a composite map including the real and the jamming information is gotten. Finally, analysis of the simulation result shows that if the radar parameters are estimated accurately, a man-made map can have a good deception jamming effect. If not it still can have a good covering jamming effect in a certain area
