摘　　要：随着数据业务和多媒体业务的快速增加,人们对定位与导航的需求日益增大。但是受定位时间、定位精度以及复杂环境等条件的限制,比较完善的定位技术目前还无法很好地利用,针对这些问题,在分析了现有几种典型的定位技术的特点和不足后,设计并实现了一套有源RFID定位系统。该系统以RFID技术为核心,利用读写器对标签进行定位。分析表明,该系统具有定位精度高,抗干扰能力强,定位范围大等特点,适用于多标签情况。With the data services and multimedia services rapidly increasing, the demand for positioning and navigation are also increasing. But a perfect positioning technology is still not used, because of the positioning time, positioning accuracy and the complex environment conditions. To address these issues, the features and issues pertinent to several current typical positioning technology were analyzed. Finally, an active RFID location system was proposed, which is based on RFID technology. Analysis shows that this system has hige positioning accuracy, strong anti-jamming capability, wide positioning range and fits for the scenario when the tags number is large.
