Abstract

In order to solve the non uniform environment of the target area influencing the variance of DF error, the weighted maximum likelihood estimation (WMLE) algorithm was proposed. In this algorithm, the effect of the target distance was introduced into MLE. we construct the weighted vector to make up for the effect when the target distance increase the variance of the DF error become worse. Theoretical analysis showed that the algorithm of WMLE could further improve the accuracy of the multi-station DF crossing localization.
