More Information
Summary:The invention discloses a multi-antenna RFID (Radio Frequency Identification) tag positioning method and system based on RSSI (Received Signal Strength Indicator), and the method comprises the steps: obtaining space coordinates of RFID tags through a mass of RSSI data provided by a constructed virtual antenna array and a real antenna array by adopting a centroid positioning method or according to the RSSI statistical distribution of the antenna array, fully utilizing the multi-antenna resources of the antenna array, and improving the positioning accuracy of the RFID tags. And the positioning precision of the RFID tag is further improved. The method is based on radio frequency signal propagation, and can be applied to various scenes related to radio frequency signal identification/positioning. 本发明公开一种基于RSSI的多天线RFID标签定位方法与系统，通过构建的虚拟天线阵列和真实天线阵列提供的大量RSSI数据，采用质心定位法或根据天线阵列的RSSI统计分布获取RFID标签的空间坐标，充分利用了天线阵列的多天线资源，进一步提高了RFID标签的定位精度。而且本发明基于射频信号传播，可应用于射频信号识别/定位相关的诸多场景中。
