Calculation of detection coverage area of a passive radar system with multi-irradiation sources

针对多源照射下外辐射源探测覆盖面积求解复杂、传统方法不够精确的问题,采用计算机辅助积分法求解计算多源照射下外辐射源雷达的覆盖面积.先以单个照射源为例计算其探测面积,并推广到三个照射源场景,计算了基线距离连续变化下的探测覆盖面积,并进行归一化处理.仿真分析表明,该探测覆盖面积计算方法是可行和实用的.该面积计算结果可用于指导多源照射条件下照射源和接收站位置的优化部署,从而提高系统探测效能.

Aiming at the problem that it is complicated to solve the detection coverage area of the passive radar system under multi-source irradiation and the traditional method used is not accurate enough,this paper uses computer-aided integral method to calculate the detection coverage area of the passive radar system based on multi-source irradiation.Firstly,the detection coverage area based on a single irradiation is calculated and then extended to the scenarios of three irradiation sources.The detection coverage area under the condition of continuously changing baseline distance is calculated,and normalized processing is also carried out.Simulation analysis shows that the proposed calculation method for detection coverage area is feasible and practical,and that the calculated area results can be used to guide the optimal deployment of irradiation source and receiving station locations under multi-source irradiation conditions,so as to improve the detection efficiency of the radar system.
