摘　　要：合成孔径雷达(SAR)是一种高分辨率成像雷达,在工作机理上不同于传统雷达,对其实施干扰及效果评估具有其特殊性。通过对受干扰前后合成孔径雷达成像的灰度方程的分析,提出了一种基于受干扰前后雷达图像相关测度的干扰效果评估方法。The syntheic aperture radar is a kind of imaging radar with high resolution,the theory is different form the traditional radar.The evaluation method of the jamming effect of syntheic aperture radar(SAR) are especial.After analysis the jammed SAR gray equation and the original SAR gray equation,a evaluation method of the jamming effect with the pertinency of the jammed image and the original image is bring out.

关 键 词：合成孔径雷达 灰度方程 相关测度 干扰效果评估
