| Abstract: | A new exact,explicit,uniterative,and computationally effcient solution of nonlinear equation set for estimation of emitter position based on the time differences of arrival (TDOA) measured by multi stations is proposed in this paper.The accuracy analysis of the location method is also presented.Finally performance evaluation results of emitter location by using TDOA information are illustrated by some graphs of Geometrical Dilution of Precision (GDOP) under various conditions in the specific surveillance region. |
