Abstract :
On the Gaussian white noise environment, based on the TDOA multi-base stations, it is presented in this paper by adding the quantities of base stations, which improving TDOA location precision method. Secondly, multi-base stations distributed situation are discussed in order to analyze the impacts to precision. At last, for the mobile targets in multibase stations, the simulation based on multi-base stations location method is carried with Friedlander algorithm, and the impact of positioning algorithm is analyzed using cumulative distribution function (CDF) as a positioning accuracy of the evaluation of different indicators for multi-base stations and different geometric distribution of base stations, simulation results show that the positioning precision of the regular polygon is lower than the arbitrary polygon.
