摘要

对基于TOA/TDOA的无线定位算法进行了研究和比较，并对基于TOA的精确测距技术进行了分析。针对现有定位算法多为二维形式的问题，将Chan算法归纳为三维形式，提出了一种基于TOA的三维定位方法。该方法利用两步加权最小二乘的初始化估计将非线性定位方程转化为线性形式，然后计算定位估计。该方法简便、准确。仿真结果表明了该方法的理论价值。

Chan Location Algorithm Application in 3-Dimension Space Location

Wireless location algorithm based on TOA/TDOA has been researched and compared, and precise ranging technology based on TOA has been analyzed in this paper. In view of the existing location algorithm is always in 2-dimension form, Chan algorithm has been concluded in 3-dimension form and a 3-dimension location method based on TOA is proposed. The method transforms the nonlinear location equation into linear form by using initialization estimation coming from two-step weighed least square, then calculates the location estimation. The method is simple and precise. The simulation about it is given to show its theoretic value.
