摘要
分析了基于TOA无线电测距的车辆定位系统,主要研究了扩展Kalman滤波算法在其中的应用以及影响定位精度的因素。仿真结果表明,测距误差为20m,定位误差(圆概率误差)可达到15m左右。
This article analyzes the central lo cating system for vehicles based on w ireless distance measuring of TOA firstly,and mainly studies the application of extended Kalman filtering algorithm.The simulated results are shown that the error may be limited in 15m when th e measuring error is 20m.
