Aiming at the practical needs for information security and personnel management under special complex environ-ment,a staff tracking and positioning method based on semi-active RFID technology is proposed because the traditional GPS po-sitioning technology can not meet the high-precision real-time positioning. A 125 Khz low-frequency exciter with adjustable exci-tation radius of 1~10 m and excitation region edge control of decimeter level was designed. The experimental system constructed by low-frequency actuator,RFID reader and dual-frequency RFID tags was tested. The test result show that the experimental sys-tem based on semi-active RFID technology is stable and its tracking information is real-time and accurate.
