摘　　要：提出基于人体遮挡应用场景下的UWB信道,通过对TOA测距误差的测量与分析,研究人体遮挡对TOA测距误差的影响。通过搭建合适的测量平台,对测量结果进行处理,建立单侧人体引起的TOA测距误差模型。利用Matlab软件仿真验证人体遮挡应用场景下TOA测距误差的准确性并分析体表爬行波对TOA测距的影响。Based on UWB channel, in which human body occlusion application scenarios, the influence of human body on TOA range error by measurement and analysis of TOA ranging error was studied. The TOA ranging error model caused by single side of human body through building a suitable measuring platform and dealing with test result was es-tablished. Then Matlab software simulation was used to verify the accuracy of TOA ranging error in human occlusion ap-plication scenarios, and the influence of creeping surface wave on TOA ranging was analyzed.
