摘要
近几年,室内无线定位技术发展迅速,在众多无线定位技术中,超宽带(Ultra-Wide Band)有着抗多径干扰能力强,定位精度高等优点,受到学术和产业界的极大关注。然而在一些复杂的工业环境,如变电站,电厂等环境下,超宽带依然会受非视距的影响,甚至某些情况下定位偏差能达到数十米。该文提出一种简单有效的超宽带非视距鉴别方法,该方法无需获取完整信道冲击响应信息,并且计算简单,适用于TDOA定位。实验结果表明该方法能够有效识别非视距影响较大的原始数据。
In recent years,indoor wireless positioning technology has developed rapidly,and among many wireless positioning technologies,Ultra-Wide Band(UWB)has the advantages of strong resistance to multipath interference and high positioning accuracy,which has received great attention from the academic and industrial communities.However,in some complex industrial environments,such as substations,power plants,etc.,ultra-wideband is still affected by non-visual range,and the positioning deviation can even reach tens of meters in some cases.In this paper,we propose a simple and effective UWB non-line-of-sight identification method,which does not require the acquisition of complete channel impulse response information and is computationally simple for TDOA localization.The experimental results show that the method can effectively identify the raw data with large non-line-of-sight effects.
