| Abstract: | A new passive localization estimate algorithm of Time Difference of Arrival(TDOA) to improve the accuracy of target localization was proposed,and the ambiguity and unsolvable problem were solved.First the traditional four stations three TDOA localization estimator and the five stations four TDOA localization estimator in the condition of one station is raised were analyzed,and then the simulation result was given.Finally the localization performance of the new estimator and the LS estimator when one station is raised and the traditional four station three TDOA localization estimator were compared. |
