摘　　要：为使无人机在飞行时尽量保持电磁静默,采用纯方位无源定位技术建立无人机定位模型,并针对具体的情形给出无人机位置的调整方案。首先,设计定位误差比较模型,针对由两架无人机作为信号发射机和由3架无人机作为信号发射机的情况进行了模型构建与仿真对比;其次,在建立了信号发射机与信号接收机之间的几何关系的基础上,利用粒子群算法构建了圆形编队智能优化模型,实现了仅用两架无人机进行定位的效率的提升;最后,将所构建的模型进行改进与推广,建立了针对锥形编队的樽海鞘群跟踪定位模型和聚合式定位模型。To keep electromagnetic silence as far as possible during the flight of UAV,this paper adopts azimuth-only passive positioning technology to establish the UAV positioning model and gives the UAV’s position adjustment scheme according to specific situations.First,a positioning error comparison model is designed,and model construction and simulation comparison are carried out for the case of two UAVs as signal transmitters and three UAVs as signal transmitters respectively.Then,based on establishing the geometric relationship between the signal transmitter and the signal receiver,the intelligent optimization model of circular formation is constructed using particle swarm algorithm,and the efficiency of positioning with only two UAVs is improved.Finally,the constructed model is improved and extended,and the conical group tracking and positioning model and the aggregation positioning model for Salpa group are established.
