Last, the paper discusses a passive positioning technology and its usage in UAVs detection and location of enemy radars.Then analyses pinpointing errors through simulations. 最后探讨了无源定位技术，并将该技术应用在无人机群对敌方辐射源雷达的定位中，建立了定位模型并仿真分析了定位误差。
Using time difference cues, a real time 3-D localization system is implemented, which is based on 6-channel TDOA estimation. 本研究利用时间差线索，实现了一个基于六通道时延估计算法的实时三维声源定位系统。
