摘要
通过测量两个点之间的脉冲发送和接收的时间差,依据电磁波传播速度,可以估算出两个节点之间的距离从而实现定位功能。利用MATLAB技术对无线定位技术进行仿真。结果表明,基于TOA的UWB定位技术能提供精确的定位精度,是无线定位技术中极具潜力的技术之一。
By measuring the time difference between the pulse sending and receiving between two points,the distance between two nodes can be estimated according to the electromagnetic wave propagation speed so as to realize the positioning function.The TOA algorithm in this paper adopts the time-of-flight method and combines AML algorithm and Taylor algorithm.Through simulation experiments,we get the average measurement accuracy of about 0.056m.
