Abstract

The invention provides a corner reflector which comprises a triangular supporting pedestal, a corner reflector body, and a pitching adjustment mechanism. The triangular supporting pedestal comprises three supporting foundations, a first support, a second support, a third support and a rotating shaft, wherein either two of the three supporting foundations are fixed via angle iron, the first, second and third supports are respectively fixed on the corresponding supporting foundations, and extend upwards along the horizontal plane, and the two ends of the rotating shaft are respectively pivoted to the upper ends of the first and second supports. The corner reflector body is of a triangular cone structure, the bottom surface of the corner reflector body is fixed on a rotating shaft of the pedestal via a welding clamping block, the two side surfaces of the corner reflector body are arranged symmetrically, and multiple pitching adjustment support lugs in different heights are arranged at a connecting position, at the back of the corner reflector body, of the two side surfaces. One end of the pitching adjustment mechanism is hinged to the third support of the triangular supporting pedestal, and the other end of the pitching adjustment mechanism is hinged to one of the multiple pitching adjustment support lugs at the back of the corner reflector body. In the corner reflector, the pitching adjustment support lugs in different heights are used to realize flexible pitching adjustment of the corner reflector body.

Description

technical field [0001] The invention relates to the technical field of radar in the electronic industry, in particular to a corner reflector. Background technique [0002] Because the synthetic aperture radar (SAR) satellite has all-weather and all-time observation capabilities, and has a certain penetration ability to the surface, it plays an important role in disaster monitoring, environmental monitoring, resource exploration and military applications, and is favored by various countries. At present, it has become a hot spot in the development of space earth observation. [0003] In order to ensure that the synthetic aperture radar system has the function of quantitative observation, improve the accuracy of synthetic aperture radar in object classification, target recognition, etc., realize large-scale, all-weather, all-weather dynamic monitoring, and maximize the application benefits, it is necessary to Synthetic aperture radar is calibrated, so establishing a synthetic ...
