The Anti-Jamming Technology for SAR Cheat Jamming Using Complex Modulated LFM Signal

Li Jiang-yuan Wang Jian-guo

摘要

摘要: 数字储频欺骗干扰是目前对合成孔径雷达(SAR)的一种有效干扰方式。该文提出利用脉间调频斜率抖动的复杂调制LFM信号，实现对数字储频欺骗干扰的抑制。由于雷达信号调制形式干扰方未知，降低了干扰信号和当前雷达发射脉冲信号之间的相关性。该文给出了在距离、多普勒二维域上的抗数字储频欺骗干扰处理方法，达到对数字储频欺骗干扰的有效抑制。

Abstract: 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.
