摘要：
The measurement system consists of receiver, transmitter and reflector. The wireless microwave is transmitted and received by the transceiver. It is important to monitor the micro-displacement of large outdoor objects in long distance in order to prevent natural disaster, such as the hill landslide and bridge distortion. The micro-displacement can be calculated out from the phase variation of the reflected microwave. This system is composed of two main parts, which are reflector and transceiver. The operation principle and implementation method of this system are introduced. The analog or digital scheme is used to realize the equipment.
