对合成孔径雷达压制干扰效果分析

Analysis of Barrage Jamming on Synthetic Aperture Radar

合成孔径雷达是一种高性能成像雷达,能全天候、实时地获取地面图像。干扰效果是衡量干扰设备能力的一个综合性的指标,干扰效果的定量评估与检测是雷达对抗中的重要课题。分析了SAR雷达压制干扰的成像原理,引用了保护距离的概念,建立压制干扰的数学模型,进行了参数的选择,并对SAR的干扰效果进行了计算机仿真,通过结果的输出,验证了通过保护距离进行压制干扰效果定量评估方法的正确性和可行性。

Synthetie Aperture Radar（SAR） is a type of high performance imaging radar. It can all - weather,all -day and timely get ground image of wide region,it has fine penetrability to vegetation and ground. Jamming effect is a comprehensive target which can evaluate the ability of jamming equipments. The evaluation and detection on jamming effect are important theories in radar antagonism. This article analyses the imagery theory of barrage jamming on SAR,introduces the concept of protective distance and builds an arithmetic model of barrage jamming. At last, this mode is simulated by computer when the parameter is settled. In compassion to the result,it can be established that this method of the quantitative evaluation on barrage jamming by protective distance is proper and effective.
