摘　　要：由于时差测量精度的提高,时差定位体制得到了广泛的应用。除量测误差外,站址误差也可能会对目标定位性能产生影响。提出了考虑站址误差的牛顿迭代方法,通过仿真实验分析了时差定位体制中TDOA量测误差及站址误差对定位性能的影响。Target location system based on TDOA measurement is widely used because of the high precision. Beside of the TDOA measurement error, the receiver positions error has serious effect on the location accuracy. In the paper, the Newton Taylor series method considering the receiver position error is proposed. Numerical simulation shows the good performance of this algorithm
