摘　　要：分析了TDOA的数学模型,通过Chan氏算法来实现基于TDOA的手机定位,最终得到可视化的仿真结果。应用组合式的TDOA估计方法进行测距定位,该系统可以解决测距精度、测距量程、测距实时性之间存在的矛盾,使得在进行通信的同时完成高精度的定位任务。Mathematical model of Time-Difference of Arrival （TDOA） was analyzed. Positioning of mobile phone based on TDOA with Chan＇s method can be realized to get a visualized simulating result. Distance measuring and positioning were achieved by a combinational estimation method of TDOA. The system can solve the contradiction among measuring precision, range and real-timing, so that high-precision positioning can be achieved during calling
