摘　　要：由于障碍物会对电磁波的传播形成遮挡效应,为了避免遮挡盲区对无源雷达系统探测性能造成影响,以接收信噪比最大为优化目标,将接收站部署区域限制和障碍物遮挡作为约束,建立遮挡条件下单站卫星外辐射源无源雷达接收站部署的数学模型,并用粒子群优化算法给出接收站最佳部署位置的求解方法。仿真分析表明:上述基于接收信噪比最大化的布站方法解决了遮挡条件下的单站卫星外辐射源无源雷达布站问题。Due to the blocking effect caused by obstacles on the propagation of electromagnetic waves,in order to avoid the impact of coverage blind spots on the detection performance of passive radar systems,with the optimization goal of maximizing the receiving signal⁃to⁃noise ratio,the deployment area of receiving stations and obstacle occlusion are taken as constraints.A mathematical model for the deployment of single⁃site passive radar stations for satellite external radiation sources under obstructed conditions is established.The particle swarm optimization(PSO)algorithm is employed to determine the solving method of the optimal deployment positions of receiving stations.Simulation analysis demonstrates that the above⁃mentioned method,based on maximizing the receiving signal⁃to⁃noise ratio,effectively resolves the deployment problem of single⁃site passive radar for satellite external radiation sources under occlusion conditions.
