摘　　要：对合成孔径雷达的干扰,是电子对抗中的重要课题。文中分析了对SAR的弹射式干扰的工作原理,从理论上对干扰信号作了距离向和方位向的分析,得到弹射式干扰的理论结果。并用Matlab模拟干扰信号,加入回波信号上一起进行成像仿真,通过对仿真结果的分析,验证了理论分析的正确性,得到了弹射式干扰的一系列性能。The jamming to SAR（ Synthetic Aperture Radar） is an important and difficult issue to electronic war- fare. This paper analyzes the works of jamming to SAR by rebound mode. Range compress and Cross-range compress is discussed in detail, and effect of jamming is got by the analysis. A method of raw data creation and data Compression is used to simulate the jamming effectiveness. By Matlab simulation, the analysis results verify that the method affect the SAR image and can cover up the protected area.
