SYSTEM FOR MEASURING DISPLACEMENT OF THE SLOPE USING A UWB RADAR AND METHOD THEREOF

摘要

The present invention relates to a system for measuring absolute displacement of a slope using a UWB radar. The system of the present invention comprises: multiple target units which are installed in an arbitrary target point of the corresponding slope to be monitored and reflect a radio wave of an incident UWB frequency band; a reference station which is installed at a point spaced from the slope to be monitored with a certain distance therebetween, transmits the radio wave of the UWB frequency band, and receives the radio wave of the UWB frequency band reflected from the target units; and a displacement measurement information processing device to detect displacement including the distance, the direction and the height for the target units based on the comparison and analysis results between radio wave data of the UWB frequency band received by the reference station and reference data of the set UWB frequency band. The system and the method of the present invention can precisely measure the displacement of the slope while determining an absolute location (coordinate) of the arbitrary target of the slope by using the UWB radar, thereby effectively detecting a collapse symptom of the slope in advance.
