摘要
间歇采样转发干扰通过对敌方雷达信号进行截获、存储、调制和转发可以在匹配滤波后产生多个假目标峰,对相干体制雷达具有较大威胁。结合对典型间歇转发干扰机理的分析,雷达方分别在接收端和发射端设计了相应的抗干扰方法,实现了对此类干扰的有效抑制。相应地,干扰方也进一步提出了多种改进方法,以提升间歇转发干扰的干扰效果。然而,鲜有研究讨论现有干扰改进方法对抗雷达抗干扰方法的效果。为解决这一问题,首先对现有研究进行梳理,总结出典型的间歇转发干扰改进方法和雷达抗干扰方法。然后,通过实验详细分析了改进方法对雷达抗干扰方法的干扰效果。仿真结果表明,改进间歇转发干扰能够有效对抗雷达抗干扰方法,提高了转发干扰的干扰能力。
Interrupted sampling repeater jamming(ISRJ)poses a significant threat to coherent radar systems by intercepting,storing,modulating,and retransmitting enemy radar signals,thereby generating multiple false target peaks after matched filtering.Based on an analysis of the typical mechanisms of intermittent forwarding jamming,the radar side has developed corresponding anti-jamming techniques at both the receiving and transmitting ends,effectively suppressing this type of jamming.In response,the jamming side has proposed various improved strategies to enhance the effectiveness of intermittent forwarding jamming.However,few studies have explored how these improved jamming methods perform against radar anti-jamming techniques.To address this gap,the existing literature and summarizes representative improvements in intermittent forwarding jamming are reviewed firstly,along with typical radar anti-jamming methods.Subsequently,experiments are conducted to analyze the effectiveness of these improved jamming techniques in countering radar anti-jamming measures.Simulation results demonstrate that the enhanced ISRJ methods can effectively confront advanced radar anti-jamming strategies,thereby significantly improving the overall jamming performance.
