摘　　要：基于弗里斯(Friis)传输模型,给出了一种基于RSSI的RFID阅读器与无源标签通信时的理论测距模型,并通过实验数据对标签进行标定,得到每个标签最终的测距模型,并与常用的对数阴影模型进行对比,实验结果表明,本文的模型有相对较高的测距精度。Based on Friis transmission model,a theoretical ranging model for RFID reader communication with passive tags based on RSSI is proposed.The final ranging model of each label is obtained by calibrating the label with experimental data,and compared with the commonly used logarithmic shadow model.The experimental results show that the model in this paper has relatively high ranging accuracy.
