从二维相关系数的角度出发，提出了一种对ISAR压制干扰效果的评估方法。该方法能清楚地反映受干扰目标从临界干扰到严重干扰整个干扰过程中目标ISAR图像失真程度；并将干扰效果评估量化在0～1之间，具有归一化的优点。就射频噪声干扰模式和调相噪声干扰模式对ISAR进行了干扰仿真，仿真结果证明了该评估方法的有效性。Based on the concept of correlation coefficient, this paper introduces an evaluation method of barrage jamming effect on ISAR. This method can reflect clearly distortion degree of the jammed target during the whole jamming process. Also, it make the evaluation of jamming effect quantify from zero to one. it has the merit of unitary. Furthermore, Two typical noise barrage jamming modes are employed in computer simulation of interference with ISAR. The result shows the method proposed is effective.
