TOA定位算法的坐标解析优化方法综述

Review of Coordinate Analysis Optimization Method Based on TOA Location Algorithm

TOA(Time Of Advent)算法被称为“到达时间算法”,是一种基于测量基站和标签之间通信信号的到达时间计算出二者之间的距离,从而进行定位的方法,但是由于存在基站与标签时钟不同步的问题,而有较大测量误差。本文基于TOA算法,对常见的二维坐标解析和三维坐标解析方法进行了综述,并总结了一些坐标解析的优化算法,以求提高TOA算法解析平面和空间坐标的精度。

TOA algorithm is known as“Time of Advent algorithm”.It s a kind of positioning method based on the flight duration of frame to calculate the distance between anchor and tag.Whereas owing to the non-synchronized clock set,there is a larger error in ranging via TOA algorithm.In the paper,the common coordinate analysis is introduced in 2D and 3D based on TOA and exposes some optimization methods to raise the accuracy of locating.
