The Performance Evaluation of Three Jamming Methods of SAR

摘要

摘要: 该文针对非相参噪声压制式干扰、欺骗干扰和一种新的类杂波干扰，分别从功率、参数精度要求、干扰效果和可实现性角度出发对3种干扰方式进行了深入分析，得出了对SAR匹配干扰的总体思路。理论分析和仿真表明基于多维调制的类杂波干扰作为一种部分匹配干扰，可以获得SAR处理增益，具有类似SAR背景杂波的统计特征，对参数精度要求不高，是目前可实现的一种对SAR干扰方式。

Abstract: In this paper, the general noise jamming, cheat jamming and a novel similar clutter jamming method are discussed. From the viewpoint of the jamming power, the precision of leading parameters and the jamming effect, the matched jamming is proposed after the theory analysis. Both the theory analysis and simulation, bring the same conclusion that the similar clutter jamming method based on the multidimensional digital modulation, matches the SARs receiver and possesses the similar statistical characteristic with the SAR background clutter. It can partly overcome SARs high processing gain and requires moderate precision of leading parameters. Therefore, it is the realizable jamming method presently.
