Abstract

To estimate system errors of direction of arrival (DOA) and time difference of arrival (TDOA) with two stations locating system, a system error estimation model is build through analyzing the locating principle. In succession sequential least squares estimation (SLSE) is studied. And then he estimation process is given. At last convergence and accuracy of SLSE are researched through Monte Carlo simulation. And target tracks which are before and after the bias registration are compared. Theoretical analyses and simulation shows that the SLSE can exactly and effectively estimate system errors of DOA and TDOA locating system.
