This paper introduces the monitoring principle and basic performance indexes of movement and surveying radar, compares it's monitoring results with accelerometer and total station. The movement and surveying radar is also used in of Baocheng railway. The test and application results indiciate the monitoring of Qingjiang 2# bridge and 7# bridge is reasonable and accurate in monitoring of vibration frequency, vibration velocity and vibration deformation for bridge healt monitoring.
