摘要 对三维定位算法进行了研究,提出了一种基于到达时间的三维定位算法。其主要思想是用一新变量代替定位估计中的二次项,把非线性估计转化为两次WLS(加权最小二乘)线性估计。该算法结构简单,计算量较小。仿真结果证明了该算法的有效性。 A 3-dimension location algorithm has been researched and a new algorithm based on TOA (time of arrival) is proposed. By using a new variable to replace the square term, the nonlinear estimation can be transformed into a two-step WLS (weighted least square) linear estimation. This method is simple and can save the computation time. A simulation about it is given to show its effectiveness.
