泰勒级数展开算法是需要初始估计位置的递归算法，在每一次的递归中通过求解TDOA测量误差的局部最小二乘来改进估计的位置。 本程序基于MATLAB，对泰勒级数展开算法进行了仿真。初始位置的选取很重要，建议和其他简单的算法进行协同，对信号源位置进行定位。 希望对研究信号源定位的同志有所帮助。(Taylor series expansion algorithm is the need to estimate the location of the initial recursive algorithm, in every recursive TDOA measurement error by solving the partial least squares to improve the position estimate. The program is based on MATLAB, the Taylor series expansion algorithm for the simulation. The selection of the initial position is very important, the proposed algorithm and other simple coordination, to locate the signal source location. Want to locate the source of research help comrades.)
