UWB测距与室内定位精度研究
Research on Accuracy of UWB Ranging and Indoor Positioning
摘要
Abstract
In this paper,through the experiment,has tested the accuracy of UWB tech-nology ranging and indoor positioning,and analyzed the error source of UWB technology ranging and indoor positioning.The data showed that UWB indoor ranging accuracy is not only effected by the multi-path and blocking,but also effected by the anisotropic of antenna group delay.And,the multi-paths effect is not the main source of the error.The ranging er-ror that the antenna group delay causes has the strong regularity,to a certain extent can treat as the systematic error to weaken it;The error that the blocking causes is most seri-ous,but can reduced through build Anchors reasonably.In brief,the precision and stability of current low cost UWB product have been able to fit the needs of some users,and It has the possibility of promotion.关键词
