摘要
该文提出了一种针对无源RFID标签的位置检测的方法。此方法将反向散射调制与地面标识相结合来估计标签的当前位置,不需要改变当前的RFID标准,利用现有的硬件条件就可以实现。文章首先介绍反向散射调制和地面标示估算标签位置的方法,并提出两种方法混合计算的优化算法流程,另外方法的改进措施也被提了出来。最后通过实验和仿真来说明这种方法的有效性和稳定性。
This paper brings up a novel method for localization of the passive RFID tag,it involves both the backscatter modulation and landmarc to estimate the current position of the tag and no need to change the RFID protocols that have existed,it can be achieved by the existing hardware.The tag position estimation process using backscatter and landmarc is introduced first,then we present the flowchart of the optimizing algorithm calculated by the mixed method,in addition,an improvement method also be proposed.In the end,the validity and stability of this method is evaluated through experiments and simulations.
