Abstract

A slope displacement monitoring radar accuracy calibration device comprises a base; a corner reflector is arranged above the base; the corner reflector comprises a lower reflecting plate; the lower reflecting plate is fixedly mounted on a sliding pedestal; the sliding pedestal is mounted on two guide rails; the two guide rails are fixed on the base in the front and back horizontal direction; a lead screw for driving the sliding pedestal is arranged between the two guide rails; a lead screw nut is screwed on the lead screw; the lead screw nut is fixedly connected with the sliding pedestal; oneend of the lead screw is drivingly connected with a servo motor; the lead screw can drive the sliding pedestal to be displaced by 0.1 mm order of magnitude along the two guide rails; the periphery ofthe bottom of the base is provided with a plurality of height-adjustable supporting legs; and a level measuring instrument is arranged on the sliding pedestal or the base. The purpose of the inventionis to provide a slope displacement monitoring radar accuracy calibration device which can quickly and accurately perform calibration on a slope radar, and can verify whether the accuracy of the radarmonitoring data meets the requirements.

Description

technical field [0001] The invention relates to a slope displacement monitoring radar precision calibration device. Background technique [0002] In mines and geological disasters, the hazards of slope landslides are large and unpredictable, threatening people's lives and property safety at all times. With the continuous development of science and technology, there is currently a method of using SAR radar to monitor slopes. The current market There are many slope monitoring radars. However, there is no calibration equipment for the slope displacement monitoring radar itself at present, and it is impossible to accurately verify whether the monitoring data of the radar is accurate. Contents of the invention [0003] The purpose of the present invention is to provide a slope displacement monitoring radar precision calibration device that can simply and quickly perform precision calibration on the slope radar, and then can verify whether the accuracy of the radar monitoring d...
