研究了欺骗性干扰条件下的逆合成孔径雷达(ISAR)干扰效果评估方法。依据宽带成像信号模型进行欺骗干扰信号仿真,对干扰前/ 后的数据分别进行ISAR成像处理,计算图像的量化指标并结合主观评估,对ISAR干扰效果进行评估。仿真实验表明:相关系数对欺骗干扰效果评估较为有效,其他指标如熵、均值、标准差、等效视数等可以当作辅助信息作为评判参考。

The jamming effect evaluation of inverse synthetic aperture radar (ISAR) under deception jamming is studied. The ISAR imaging is performed before and after the jamming by simulating the jamming signal and using the target broadband data actually measured by the target characteristic measurement radar. The quantitative index of the image is calculated and combined with the subjective assessment method to evaluate the ISAR jamming effect. The result shows that the correlation coefficient is more effective in assessing the effect of deception, other indicators such as entropy, mean, standard deviation and equivalent visual field can be used as auxiliary information as a reference.
