摘　　要：合成孔径雷达(SAR)通过二维相关处理获得了距离-方位二维处理增益,有很强的抗干扰能力。介绍了两种对SAR的噪声干扰样式,就射频噪声干扰模式和调频噪声干扰模式对SAR实测数据成像进行了仿真。最后采用等效视数评估方法对仿真的干扰结果进行了对比分析,结果表明射频噪声压制干扰是一种较好的干扰模式。Synthetic aperture radar（SAR） can get range-azimuth 2D processing gain through 2D correlative processing,has better anti-jamming capability.This paper introduces two kinds of noise jamming modes on SAR,simulates the imaging of SAR data from actual measurement based on radio frequency（RF） noise jamming mode and frequency modulation（FM） noise jamming mode,compares and analyzes the jamming results of simulation by using the equivalent number of looks evaluation methods.The results indicate that the RF noise blanket jamming is a better jamming mode.
