| 摘 要： | 现代雷达广泛使用脉冲压缩、MTD处理等相干处理方法,具有较大的信号处理得益,抗干扰能力明显提高。DRFM可对雷达信号进行长时间的相干存储,是干扰现代相干体制雷达的重要手段。传统的DRFM干扰采用信号存储然后多次转发的干扰方法,获得的假目标数量少且干扰机能量利用率低。文中在前人算法基础上,提出一种密集假目标干扰实现方法。该方法可以灵活控制假目标之间的间隔和产生的假目标个数,并且通过设置不同的假目标距离间隔既可实现密集假目标欺骗干扰效果,也可实现压制干扰效果。理论分析和干扰仿真证明,该方法具有良好的实用价值。

| Abstract: | Coherent techniques such as pulse compression and MTD are widely used in modern radar for better anti-interference ability obviously.DRFM,which can store the coherent radar signal for a long time,is an important method for modern coherent radar jamming.Based on the DRFM interference,an efficient method for achieving intensive false target jamming is proposed in this paper.The number of false targets and the interval between false targets can be flexibly controlled by this method.Theoretical analysis and interference simulation demonstrate its good performance and potential practical value. |
