摘要
针对临近空间高超声速目标跟踪制导雷达的搜索空域划分问题,提出了基于修正球坐标系的搜索空域模型确定方法。在给出预警引导信息在修正球坐标系下的描述形式基础上,建立了静态搜索空域确定模型,并利用目标的速度引导信息,对搜索空域的动态匹配模型进行研究。仿真结果表明,该方法实现了目标高超声速运动条件下,跟踪制导雷达对临近空间高超声速目标的连续高概率覆盖,相应提高了雷达的搜索性能。
For the problem of the airspace searching division of tracking and guidance radar of near space hypersonic targets,a method for confirming the airspace searching model based on modified spherical coordinates is presented.Firstly,on the basis of the given descriptive form of early warning guidance information under modified spherical coordinates,the static confirmed airspace searching model is established.Then the dynamic matching model of the airspace searching is studied by using the speed guidance information.The simulation results show that the method makes the tracking and guidance radar capable of covering continuously with of the near space hypersonic targets in hypersonic movement high probability,and improves the searching performance of the radar accordingly.
