| 摘 要： | 针对Chart定位算法在非视距（NLOS）环境下定位性能较差的缺点，提出一种基于多基站TOA区域质心修正的Chart定位算法，该算法利用Chan算法初始定位，再通过TOA区域质心校正，以提高定位精度。仿真结果表明，该算法有效减小了NLOS误差对定位估计的影响，在NLOS误差较大的环境下仍具有良好的定位精度，性能优于Chart算法和Chan-Taylor协调定位算法。

| Abstract: | Due to Chan location algorithm＇s poor performance in Non-Line-Of-Sigh （NLOS） environment, the Chan location algorithm based on the TOA centroid position was proposed. The initial position was calculated with Chan＇s algorithm, then this algorithm through TOA centroid position correction, so as to improve the positioning accuracy. The simulation results expatiate that the location algorithm is effective to reduce the impact of NLOS error of position estimation and the location accuracy is significantly improved in worse NLOS environment, and the performance of this algorithm is better than Chan＇s algorithm and Chan-Taylor＇s algorithm as well. |
