%X The Digital Radio Frequency Memory Cheat Jamming (DRFMCJ) is an effective jamming method to SAR. This paper puts forword a method to generate the complex modulation LFM signal using the slope wobble in different Pulse Repetition Interval (PRI). Because the modulated form of the LFM signal in different PRI is not known to the jammer, which destroies the correlation of the jamming signal and the SAR transmitted signal in the current PRI. In this paper, the two dimension processing method to anti-jam on the range and doople fields is presented, which achieve the valid result to eliminate the digital radio frequency memory cheat jamming.
