摘要
针对电缆隧道狭窄长的空间特点,基于UWB定位技术,改进TDOA测距方案,提出基于双向双边TDOA测距的Chan算法与麻雀搜索算法融合的协同定位算法,降低多径环境信号干扰影响,优化初值,提高定位精度和计算效率。
This article focuses on the spatial characteristics of narrow and long cable tunnels,improves the TDOA ranging scheme based on UWB positioning technology,and proposes a collaborative positioning algorithm that combines the Chan algorithm based on bidirectional bilateral TDOA ranging with the sparrow search algorithm to reduce the interference of multipath environmental signals,optimize initial values,and improve positioning accuracy and computational efficiency.
