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。
Aiming at the problem of small search airspace bitmap in near space hypersonic target tracking guidance radar, the influence of the bitmap arrangement pattern and the beam broadening effect on the bitmap arrangement is analyzed. The optimized bit pattern of tracking guidance radar is given And the beam broadening effect compensation method. Secondly, based on the construction of the mathematical model of static optimal bit arrangement, the genetic algorithm (GA) is used to solve the global optimization problem. Based on genetic algorithm (GA) Model determination method. Finally, the dynamic matching of the wave pattern is completed by using the speed guidance information of the early warning system, and the update time of the dynamic matching is given. The simulation results show that the proposed method can achieve continuous high probability coverage of the search airspace under the target hypersonic motion, and improve the intercepting performance of the radar and avoid the waste of radar search resources.
