| 摘 要： | 基于接收信号强度指示(RSSI)测距的定位方法容易实现、开销少，适合在射频识别(RFID)系统中使用。由此提出一种RSSI在UHF频段下RFID读写器中的实现方式。使用合适的测量方法，通过对无线电传播路径损耗模型及大量实测数据的分析，证明得到的标签RSSI可以用于对无源标签的实时距离定位。

| Abstract: | Location methods based on Received Signal Strength Indicator(RSSI) are adapt to RFID systems because they are easy to realize and have low overhead. This paper presents implementation method and applications of RSSI in RFID reader of UHF band. By using appropriate measurement means and analyzing the radio propagation fading model and a large number of measured data, it proves that the RSSI of tags can work on real-time location for passive tags. |
