摘要
A monostatic 2-D asynchronous positioning system using ultra-wideband (UWB) angle of arrival (AOA) is proposed. Meter-level position of the target can be determined by using the azimuth angle and pitch angle information obtained from a single antenna array packed in one base station, without the need of time coherence between the tag and the base station. Time difference of arrival (TDOA) between three antenna elements is precisely obtained in pico-second resolution and used to derive the AOA of the tag. The system fulfills the requirements of meter-level accuracy with low cost, while providing centimeter-level accuracy in multistatic TDOA system setup. The system was tested in real indoor scenario and achieved 5 degrees' pitch resolution and 10 degrees' azimuth resolution, which means meter-level position accuracy in room-scale applications.
