对SAR干扰效果的评估是比较复杂和困难的，目前国内外的公开报道中未见到好的评估方法。从欧几里德距离空间的概念出发，提出了一种对SAR压制干扰效果的评估方法。文章就几种典型的噪声压制干扰模式对SAR的干扰进行了计算机仿真，并采用该方法与传统的评估方法对干扰效果进行了对比评估。结果表明，该评估方法具有客观、定量、一致性好的优点。

It's very complicated and difficult to evaluate the jamming effect on SAR, there is no good evaluating technique published up to now. Basing on the concept of Euclid distance space, this paper introduces an evaluation technique of barrage jamming effect on SAR. Several typical noise barrage jamming modes are employed in computer simulation of interference to SAR. Comparison between the new evaluation method and traditional one has been carried out, which shows that the former one enjoys such advantages as objective, quantitative and of high consistency. [
