摘要

射频识别技术(RFID)在许多应用领域得到了广泛的应用。然而，由于多路径等因素的干扰，目前的室内定位系统精度不高。为了提高室内定位系统的精度，本文提出了一种基于差分的全息定位方法。在初始全息图的基础上计算差分全息图来定位目标。已经进行了几个实验来评估定位性能。实验结果表明，naïve全息图方法和基于差分的全息图方法在精度上都优于基于增强到达相位差(PDOA)的方法，并且基于差分的全息图方法比naïve全息图方法精度更高。

Differential Based Hologram RFID Indoor Localization Method

Radio Frequency Identification (RFID) has been widely used in many application domains. However, current indoor positioning systems are lack of accuracy due to the interference of multi-path and other factors. In this paper, a differential based hologram localization method has been proposed to improve the indoor positioning system accuracy. A differential hologram is calculated to locate target based on the naive hologram which is generated at first. Several experiments have been conducted to evaluate localization performance. Based on the experimental results, both the naïve hologram method and the differential based hologram method are better than enhanced Phase Differential of Arrival (PDOA) based method in terms of accuracy, and the results also reveal that the differential based hologram method is more accurate than the naïve hologram method.
