ABSTRACT

In indoor positioning applications, UWB technology can achieve centimeter-level positioning accuracy, and has good resistance to multipath interference and weakness, as well as strong penetration. However, due to the complex and changeable indoor environment, UWB communication signals are easily blocked. Although UWB technology has penetration capability, it still produces errors. When there is strong interference, abnormal fluctuations of data will occur, and indoor positioning cannot be basically completed, or even serious accidents will occur. Therefore, the problem of ultra-wideband (UWB) precise location under signal interference becomes an urgent problem to be solved. An algorithm is established to find the correct distance between the "abnormal data" processed by the minimum sum of absolute distance differences and "normal data". Optimal target optimization A model based on shark optimization and UWB localization based on least square method are used to establish a comparison model, using shark optimization model can better calculate the exact location of Tag point.
