Problems solved by technology

[0003] At present, in the typical systems at home and abroad, the accuracy of ground-based lidar to obtain terrain information is relatively high, but the accuracy in deformation monitoring is relatively low; the airborne lidar technology mentioned in "Study on Large-scale Artificial Slope Stability Ground-Based InSAR Monitoring" is used for Deformation monitoring is quite difficult and the accuracy is poor; "Application of Synthetic Aperture Radar Differential Interferometry in Seismic Deformation Monitoring" introduces the Synthetic Aperture Radar Interferometry (InSAR) technology that uses two SAR images to obtain high-precision three-dimensional elevation information on the ground
[0004] The above domestic and foreign micro-variable sensing radars have problems such as fixed field of view, large space occupation, and difficulty in portability, which limit their further wide application and are difficult to meet the needs of mine slope displacement monitoring

Abstract

The invention discloses an azimuth scanning positioning mechanism and a radar system. The azimuth scanning positioning mechanism comprises a casing, a power module and a flange, wherein the power module is arranged inside the casing; a first opening is disposed at the top of the casing; the flange is disposed over the first opening and is connected with the power module through the first opening;and the power module rotates the flange so as to drive a radar fixed to the flange to rotate and scan. The radar system uses the azimuth scanning positioning mechanism. The flange connection manner increases the field angle of the radar and provides the radar with a larger field of view. In addition, the power module is housed in the casing so as to be compact in structure and easy to transport. The azimuth scanning positioning mechanism solves the defects that the azimuth scanning positioning mechanism of a conventional micro-change sensing early warning radar control system has a fixed fieldangle and a large size and is not easy to carry.

Description

technical field [0001] The invention relates to a slope radar system device, in particular to a compact azimuth scanning and positioning mechanism for a micro-variation sensing early warning radar. Background technique [0002] The micro-variation sensing radar system is mainly used in slope deformation monitoring technology. It has the technical advantages of non-contact, high-precision, large-area, all-weather, and 24-hour continuous monitoring.
