摘　　要：位置信息是构建智慧城市和物理信息融合系统的基本要素,利用射频识别(RFID)技术对带有射频标签的物体或人员进行位置感知被视做是提供室内"最后一米"精准位置信息的关键。为推进RFID位置感知技术研究,主要从参数提取和位置估计方法两方面对RFID标签位置感知关键技术的发展现状进行了总结;探讨了诸如远距离通信、标签技术等与位置感知相关的各类技术及其应用场景;最后指出了RFID位置感知技术的未来发展方向。Location information is one of the basic elements for smart city and cyber-physical system. Using RFID-based locate awareness technology to locate the tagged object or human is regarded as a significant solution to provide the accuracy location information of the indoor"last one meter". This paper gave a survey of RFID-based tag location awareness technology.This paper mainly separated RFID-based tag locationaware technology into two parts as feature extraction and localization estimation,and summed up and concluded currently relative researches. In addition,it explained the relative RFID technologies that would introduce possible impact for positioning accuracy and anti-jamming capability such as long range communication and new tag design,as well as a detailed study of application scenarios. At the end,it concluded and figured out the future trends and challenges for RFID-based location awareness technology.
