| 摘 要： | 对基于TOA/TDOA无线定位算法进行了研究和比较,分析了基于TOA的精确测距技术.针对现有的定位算法通常是二维形式的问题,在Chinl定位算法基础上推导了Chan算法的三维形式,提出了一种基于TOA的三维空间定位算法.算法的主要思想足两次使用加权最小二乘法(WLS)得到初始解,利用初始解将非线性定位方程组线性化,最终得到位置估计.仿真结果表明该算法结构简单,精度较高,有较强的理论参考价值.

| Abstract: | 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 that the existing location algorithm is always in 2-dimensional form,Chan algorithm has been concluded in 3-dimensional form and a 3-dimensional 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 calcula... |
