摘　　要：介绍了测向测时差定位的基本原理，利用运动辐射源的ＴＯＡ和ＤＯＡ测量信息，采用批数据速推的扩展卡尔曼滤波算法对运动辐射源进行快速定位与跟踪，并通过典型航路的仿真对算法性能作了评估。This paper introduces the fundamental principle of locating by measuring direction and time differences. Based on the TOA and DOA measurement information of moving emitters, this paper adopts batch data extended Kalman filter algorithm to complete passive locating and tracking rapidly. The performance of the algorithm is evaluated with the help of computer simulation for typical target paths.
