论文摘要
提出了一个超宽的带宽（UWB）远程驱动的定位系统，用于在空间站内跟踪浮动对象的潜在用途。它利用了无电池标签，这些标签通过UHF频段中的无线电源传递来供电，并在3-5 GHz UWB频段中嵌入了节能脉冲发生器。该系统已安装在ESA火星漫游者原型上，以证明其功能和性能。实验结果表明，在大于10米的距离处，厘米级定位精度的可行性，具有使用UHF RFID频带中2W-ERP电源来确定多个标签的位置的能力。
An ultra-wide bandwidth (UWB) remote-powered positioning system for potential use in tracking floating objects inside space stations is presented. It makes use of battery-less tags that are powered-up and addressed through wireless power transfer in the UHF band and embed an energy efficient pulse generator in the 3-5 GHz UWB band. The system has been mounted on the ESA Mars Rover prototype to demonstrate its functionality and performance. Experimental results show the feasibility of centimeter-level localization accuracy at distances larger than 10 meters, with the capability of determining the position of multiple tags using a 2W-ERP power source in the UHF RFID frequency band.
