摘　　要：压制式干扰效果评估一直是SAR对抗评估中的难点,大多数评估方法是从灰度值本身的变化来评估干扰的好坏,并没有从SAR图像具有的纹理特征角度分析干扰效果。针对此问题,提出了一种基于灰度共生矩阵的SAR图像评估方法,加入射频噪声干扰,利用灰度共生矩阵得到的纹理特征的不匹配度来评估压制式干扰效果。仿真实例表明了方法能够定量地描述压制式干扰的效果。Evaluation of the effect to suppress jamming on SAR has been assessed against the difficulties, most of the evaluation methods are based on the change of the gray value itself, and not based on the SAR image texture property. A based gray level co-occurrence matrix for SAR image evaluation method is studied, which adds radio frequency noise, and analyses non-match degree of texture property to evaluate the effect of suppress jamming. The simulation results show that the method quantitatively measures suppress jamming.
