The Improvement of Passive Location Algorithm Based on Time Sequence Estimation

The multi station time difference sequence of arrival method is a kind of passive location method for pulse radiation source. It takes the advantage of mass time difference information obtained in a very short time to locate the radiation source. This paper models the time difference sequence of arrival process and estimates the time difference according to the characteristic of the time difference sequence. The simulation results show that, the localization after time sequence estimation algorithm can achieve higher positioning accuracy.
