摘　　要：针对临近空间高超声速目标跟踪制导雷达的小搜索空域波位编排问题,首先,分析了波位编排样式和波束展宽效应对波位编排的影响,给出了跟踪制导雷达较为优化的波位编排样式以及波束展宽效应补偿方法;其次,在构建静态最优波位编排数学模型的基础上,利用遗传算法具有解决全局最优问题的优势,提出了基于遗传算法(GA)的静态最优波位编排模型确定方法;最后,利用预警系统的速度引导信息完成波位编排的动态匹配,给出了动态匹配的更新时间。仿真结果表明,本文方法实现了目标高超声速运动条件下,跟踪制导雷达对搜索空域的连续高概率覆盖,相应提高了雷达的截获性能,且避免了雷达搜索资源的浪费。For the problem of beam position arrangement in a small search region/or tracmng ano gulcnng radar of near space hypersonic targets, a new method for confirming the optimal model is proposed. Firstly,based on the analysis of different beam position arrangements＇ influence on the energy requirements and search performance of tracking and guiding radar, the optimal beam position arrangement patterns are given in this paper. According to the analysis of the beam width extension influence on beam position arrangement,the compensation method for beam width extension is also given. Then, based on the static optimal beam position arrangement model, a method for confirming the static optimal model with genetic algorithin （GA） is presented. At last, the dynamic matching of the beam position arrangement is studied by using the speed guidance information,and the update time of the dynamic matching is also given. Simulation results show that the proposed method makes the tracking and guiding radar capable of covering continuously with high probability for the targets in hypersonic movement, improves the detection performance of the tracking and guiding radar, and avoids the waste of search resources.
