标准摘要
[中文适用范围]： 本文件定义了基于反射调制技术的RFID标签定位方法，具体适用于符合ISO/IEC 18000-4、ISO/IEC 18000-61、ISO/IEC 18000-62、ISO/IEC 18000-63和ISO/IEC 18000-64标准的RFID标签。 系统包括询问器（也称为读写器）和标签（也称为应答器）。通过向标签发送调制射频信号，询问器接收来自标签的信息。标签通过调节其天线反射系数来响应，从而将信息信号回传给询问器。 本文件描述了用于定位的信号、从接收到的信号中提取定位信息的方法以及对标签和询问器的要求。 [外文原描述]： This document defines how to use the RFID air interface standards of the ISO/IEC 18000 series that are based on backscatter technology for localization of RFID tags, specifically tags which are ISO/IEC 18000‑4, ISO/IEC 18000‑61, ISO/IEC 18000-62, ISO/IEC 18000-63 and ISO/IEC 18000-64 compliant. This document specifies the physical and logical requirements for localization. The system comprises interrogators, also known as readers, and tags, also known as labels. An interrogator receives information from a tag by transmitting a modulated RF signal to the tag and the tag responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the interrogator. The modulated RF signal for data exchange is based on the relevant part of the ISO/IEC 18000 series and, in addition, there is a superimposed modulated RF signal with the same or different carrier frequency intended for localization. This document describes the signals required for localization, the method to derive localization information from the signals received by the interrogator and the requirements onto tags and interrogators.
