Problems solved by technology

[0004] In practical applications, in order to facilitate the identification of targets and enhance their scattering intensity, corner reflectors are often arranged in the target area. These corner reflectors are simple in structure and difficult to orientate. The corner reflector is fixed and cannot be quantitatively displaced and rotated, which is not conducive to the quantitative research of ground-based InSAR technology

Abstract

The invention relates to the field of radar measurement and provides a corner reflector for calibrating echo signals of a foundation radar. The corner reflector comprises a metal plate assembly for enhancing the backward scattering capacity of radar waves, an adjustment device for adjusting the spatial position of the metal plate assembly and a base provided with the adjustment device. The adjustment device comprises a baseplate rotatably arranged on the base, the metal plate assembly is rotatably arranged on the baseplate, and the rotation axis of the metal plate assembly is perpendicular tothat of the baseplate. According to the corner reflector, since the baseplate and the metal plate assembly can rotate and the rotation axis of the metal plate assembly is perpendicular to that of thebaseplate, the angle of the metal plate assembly can be adjusted, and the backward scattering capacity and sensibility of the radar waves of the corner reflector are improved.

Description

technical field [0001] The invention relates to the field of radar measurement, in particular to a corner reflector used for calibration of ground-based radar echo signals. Background technique [0002] At present, the types of deformation monitoring technology are mainly divided into three categories: one is the traditional observation technology based on level, theodolite, total station and GPS; the other is space earth observation technology represented by GPS and spaceborne radar interferometry. ; The third is based on ground-based laser radar (TLS) and ground-based radar interferometry (GB-SAR)-based ground monitoring technology. In the early days, the first type of technology was usually used to observe the selected point at different time coordinates and calculate its deformation. This type of method has high precision, but it can only observe the deformation and displacement of a certain number of points, and it is difficult to fully obtain the entire research area....
