Abstract
For Time Difference Of Arrival TDOA location based on multiground stations scene two direct solution methods are proposed to solve the target position in TDOA location Therein the solving methods are realized in the rectangular and polar coordinates On the condition of rectangular coordinates first of all it solves the radial range between the target and reference station then calculates the location of the target In the case of polar coordinates the azimuth between the target and reference station is solved first then the radial range between the target and reference station is figured out finally the location of the target is obtained Simultaneously the simulation and comparison analysis are given in detail and show that the polar solving method has the better fuzzy performance than that of rectangular coordinateSupported by the National Natural Science Foundation of China No 60825104 61072107 the National Postdoctor Fundation No 20090451251 the Shaanxi Industry Surmount Foundation 2009K0831 and the Fundamental Research Funds for the Central Universities JY10000902025 of China
