摘要
相比于传统的干扰样式,间歇采样转发干扰能够巧妙利用脉压雷达的匹配滤波特性,对线性调频脉压雷达产生更有效的干扰。将移频干扰与间歇采样转发干扰相结合,从原理上分析间歇采样移频转发干扰方法,研究移频量对干扰效果的影响,最后给出随机移频转发干扰样式仿真结果,验证了间歇采样移频转发干扰方法的灵活性。
Compared with conventional interference mode, the interrupted-sampling and repeater jamming (ISRJ) is more effective for LFM radar, because of using matching filter characteristic smartly. Based on interrupted-sampling and repeater jamming methods, shift-frequency and ISRJ is combined together, and ISRJ based on shift-frequency is analyzed in elements, then the jamming effect of varied magnitude of shift-frequency is studied. Finally, this simulation results of random shift-frequency and repeater jamming is offered, which validates the flexibility of the proposed method.
