Abstract

This paper simply introduced the 3-D TDOA (time difference of arrival) position location principle of moving emitter and the position location algorithm which based on the one time measurement of TDOA. Further more this paper presented a batch processing algorithm which uses a batch of continuous TDOA measurements to compute the target position. Considering three different sites deployments, we fundamentally show the correlation between location precision and radar arrangement The simulation results show that the location precision of batch processing is much better than that of the proposed algorithm
