摘　　要：室内定位有多种方案,如蓝牙到达角度(Angle of Arrival,AOA)、Wi-Fi、接收信号强度指示(Received Signal Strength Indication,RSSI)及超宽带(Ultra Wide Band,UWB)等。在多目标定位、低成本、低功耗场景下,超高频无源射频识别(Radio Frequency Identification,RFID)具有显著优势。为实现室内多物品快速定位,将超高频无源RFID技术与相控阵技术相融合,建立一套室内定位系统。There are various indoor positioning solutions,such as Bluetooth Angle of Arrival(AOA),Wi Fi,Received Signal Strength Indication(RSSI),and Ultra Wide Band(UWB).In multi-target positioning,low-cost,and low-power scenarios,ultra-high frequency passive Radio Frequency Identification(RFID)has significant advantages.To achieve rapid indoor multi item positioning,a set of indoor positioning system is established by integrating ultra-high frequency passive RFID technology with phased array technology.
