To solve the problem of passive locating of external emitter，a batched processing algorithm is proposed for the parallel execution of multi-target locating and trajectory processing based on Direction of Arrival (DOA) and Time Difference of Arrival (TDOA). First，initial locating states of the external emitter are evaluated according to the geometry theory. Then，the trajectories are initialized according to the valid locating value. After that，the Advanced Multiple Hypotheses Tracking (AMHT) algorithm is designed for the data association between measurement trace points and trajectories of targets.The Extended Kalman filter is deduced along with the measurements from DOA and TDOA (DT-EKF)，which is used for maintaining the trajectory.Simulation results show that the proposed algorithm can perform simultaneously locating and trajectory processing for multiple targets，and acquire higher locating performance than that of the traditional methods.
