摘要： 针对无源射频识别（RFID）定位问题，建立了重叠的读写器天线布局规划以及年轮式概率模型，提出了重叠年轮式定位算法，并通过Kp值修正以及双标签边缘修正实现精确定位.验证表明，与邻近算法相比，重叠年轮式无源RFID定位算法使定位误差降低了33.929%，同时定位误差概率累积分布曲线的收敛速度也显著提高.

Abstract: To solve the radio frequency identification(RFID) positioning problem, reader antennas’ layout and a growth ring probability model were established. Then, a growth ring positioning algorithm which uses Kp modification and double-tags-edge-revising was proposed to realize accurate positioning. The experimental results show that, compared to the proximity algorithm, the overlapped growth ring passive RFID positioning algorithm decreases the positioning error by 33.929% and the cumulative probability function of positioning error reaches high probability values faster.
