摘　　要：由于逆合成孔径雷达(ISAR)是一种新体制雷达,一些用于评估常规体制雷达干扰效果的方法和手段对于ISAR来说并不适用。综合考虑雷达干扰的原理和图像处理的理论,从ISAR目标识别的角度出发,提出了一种新的对ISAR压制干扰效果的评估方法,即采用干扰前后ISAR目标识别特征中矩的变化来定量评估干扰效果,仿真结果表明了评估方法的正确性和有效性。Some methods used to evaluate the jamming effect of common radar are unsuitable to ISAR because of its new work system. Considering the principle of radar jamming and the theory of image disposal, a new evaluation method of barrage jamming effect on ISAR is proposed from the view of target recognition. The jamming effect through calculating the difference of two picture＇ s moment characters is evaluated. The simulation proves the correctness and effectiveness of the method.
