Abstract

The invention provides a detection method for deformation monitoring radar accuracy, including erecting a device end and a target end, manually setting the variation of the slant distance between the radar antenna and the corner reflector, and calculating the optical prism and angle of the target end according to the variation. Adjust the horizontal displacement adjustment of the reflector and the adjustment angle of the pitch angle of the corner reflector, and adjust the optical prism and corner reflector at the target end to the measuring point according to the horizontal displacement adjustment and adjustment angle, and the radar measures the displacement; then according to the measuring point Check the difference between the theoretical slant distance between the total station and the optical prism and the slant distance measured by the total station, and the difference between the theoretical pitch angle of the total station at the measuring point and the pitch angle measured by the total station, and the check is qualified Then, the displacement measured by the radar is compared with the artificially set change to obtain the radar accuracy information. The present invention provides a brand-new method for detecting radar precision, which is easy to operate; in addition, the present invention also provides a detecting device used in the above-mentioned deformation monitoring radar precision detecting method.

Description

technical field [0001] The invention relates to the technical field of relative displacement accuracy detection of electromagnetic wave radar equipment, in particular to a detection method and device for deformation monitoring radar accuracy. Background technique [0002] At present, the more commonly used means of geological displacement monitoring are GNSS, total station and other equipment. At present, a variety of electromagnetic wave ground-based radars have been developed at home and abroad for application in this field, mainly orbital and rotary. The measurement accuracy of radar is very important for geological displacement monitoring, and the measurement accuracy will directly affect the monitoring results. At present, there is no suitable detection method for the measurement accuracy of electromagnetic wave ground-based radar. [0003] To sum up, there is an urgent need for a method and device for detecting the accuracy of a deformation monitoring radar to solve t...
