摘　　要：针对Taylor级数展开算法进行了改进,用残差加权算法的定位结果作为Taylor算法的初始值进行迭代计算,并利用最小残差代替实际中不易获取的TDOA测量均方误差。仿真结果表明,该算法能有效地抑制非视距传播误差的影响,且性能稳定。The Taylor series expansion algorithm is improved in this paper by using located results of the residuals weighted algorithm as the initial values of the Taylor method,and utilizing the minimum residuals instead of the mean square error in the TDOA which is not easy to obtain in practice.The simulation results show that this algorithm can effectively suppress the influence of NLOS error in location estimate,and has good stable characteristics.
