摘要
随着逆合成孔径雷达(ISAR)在军事领域得到越来越广泛的应用,对其实施有效的干扰及效果评估方法已成为研究热点.文中基于图像准则,提出运用图像均值、方差、等效视数和图像动态范围等图像评估度量指标,在不同干扰样式和不同干扰工作方式条件下,对ISAR压制干扰进行了定量的干扰效果评估,给出了供工程参考的有效干扰JSR门限值.仿真结果验证了评估的正确性、可行性和有效性.
With the increasing application of ISAR in military field, it is necessary to work out efficient countermeasures and methods for evaluating the jamming effectiveness. The paper presents and evaluates the jamming effectiveness against ISAR quantitatively by adopting indexes of image evaluating such as mean value, image variance, ENL and image dynamic range based on image principle. The evaluation carries out under different noise modulated jamming and various working modes. The JSR threshold of successful jamming is presented for reference in engineering. Simulation results verified the correctness, feasibility and validity.
