摘要
根据目前反导雷达使用宽带信号对目标进行一维成像,检测目标几何特征的特点,从弹道导弹(BM)弹头雷达一维像(HRRP)特征出发,参照宽带线性调频雷达成像原理,讨论了对BM弹头HRRP可采取的几种电子干扰措施,包括对BM弹头HRRP的模拟和遮盖,给出了模拟BM弹头HRRP时所需生成的各信号特征,分析了每种遮盖干扰信号的功率利用情况,最后分析了每种干扰措施的优缺点。
Accordi check the target geome ng to the current fact that imaging radar uses broadband signal to image target and try parameter and distinguish target. Based on BM warhead HRRP characteristics and the work principle of broadband linear frequency modulation（LFM） imaging radar, several methods to jam BM warhead HRRP, including blanket jamming and BM warhead HRRP simulating are analyzed, and all signal characteristics necessary for simulating BM warhead HRRP are presented. Moreover, power utilization efficiency of each jam signal is also analyzed. At last the advantage and disadvantage of each method are discussed.
