摘　　要：研究了针对跟踪雷达的分布式协同干扰策略。针对分布式干扰系统中存在的各干扰机之间协同性不够、干扰资源浪费问题,提出了基于延迟自相关和双门限检测的分布式干扰协同策略。该方法通过实时分析接收信号信噪比,从而判断出跟踪雷达天线的方向,选择跟踪雷达主瓣方向内的干扰机实施干扰。仿真结果表明该方法实现了分布式干扰系统内部的智能化协同,以牺牲微小的干扰效果为代价,换取了对干扰资源利用率的大幅提升,有利于延长分布式干扰系统的作战时间、提高分布式干扰系统的战场生存能力。The distributed cooperative jamming strategy for tracking radar is studied.Aiming at the problems of insufficient coordination among jammers and waste of jamming resources in the distributed jamming system,a distributed jamming cooperation strategy based on delay autocorrelation and double thresholds detection is proposed.By analyzing the signal-to-noise ratio of the received signal in real time,the direction of the tracking radar antenna is determined,and the jammer in the direction of main lobe of tracking radar is selected and jammed.The simulation results show that this method realizes the intelligent coordination within the distributed jamming system,and greatly improves the utilization of jamming resources at the expense of small jamming effect,which is conducive to prolong the combat time of the distributed jamming system and improve the battlefield survivability of the distributed jamming system.
