The invention discloses a dynamic target positioning system and method with RFID information and laser information integrated. A particle filter is used to integrate RFID signals and laser signals, thereby realizing accurate positioning on a dynamic target. The information acquired by the laser sensor is subjected to clustering processing, and the information after laser clustering at adjacent time is processed as a target speed. The RFID label signal intensity and the label phase information are acquired at the same time, the acquired signal intensity information is integrated to a particle filter updating stage, and the phase information at the adjacent time is processed as a target speed. Finally, the speed estimated by the laser information after clustering is matched with the speed estimated by the RFID phase, the best matched speed is selected and integrated in the article filter updating stage, and thus, a moving target can be positioned more accurately. 本发明公开了种融合RFID信息和激光信息的动态目标定位系统及方法，利用粒子滤波器将RFID信号与
