摘要
Abstract
In the paper,an indoor positioning system based on UWB wireless sensor network is proposed.the time difference is obtained through the interaction between the anchor node and the label node information,which is transmitted to the host computer by the nRF24L01.The host computer calculate the position of the target object using the improved TDOA algorithm and calman filtering algorithm,and is displayed in the computer.The experiment results show that the system ultimately makes the indoor positioning is about up to 20 cm or so,the system has anti-multipath capability and high stability,it provides more reference for the wireless sensor network positioning.关键词
