Technical Field

Background
Synthetic Aperture Radar (SAR), as an active electromagnetic wave sensor, has the capability of observing the earth all day long and all weather, and is one of the important means for acquiring geospatial information by the aerospace remote sensing technology. The triangular reflector (CR) installed on the ground enhances the strength of the backward scattering signal by reflecting the electromagnetic wave pulses emitted by the SAR satellite multiple times, so that it appears as a target with a higher signal-to-noise ratio in the SAR intensity image and can be easily identified. Due to the extremely strong reflection echo characteristic, the corner reflector is widely applied to radar radiation correction and earth surface deformation monitoring.
In order to achieve an optimal reflection effect for the electromagnetic wave pulse, the corner reflectors need to be correspondingly and accurately oriented for different SAR satellite sensors when actually installing the corner reflectors. During specific installation, the orientation of the corner reflector is required to be perpendicular to the SAR satellite course, and the center pointing line of the corner reflector is aligned with the radar incidence direction. To ensure this, the three struts of the mounting bracket require two front posts to be shorter and equal in length, and the other rear post to be longer, so that the center point of the corner reflector is aligned with the incident direction of the radar pulse by adjusting the height difference between the rear post and the two front posts. In order to prevent the electromagnetic waves from being reflected because of the accumulated water generated in the field, a small hole is drilled at the bottom of the corner reflector for draining water. In order to reduce the resistance to wind, perforated aluminum plates are usually used to form the reflecting surfaces. When choosing the installation site, it is generally ensured that no strong reflectors interfere within 30 meters around the corner reflector. In addition, the corner reflector is required to be fixed at a stable position, the corner reflector is generally fixed on a cement pier, the bottom of the cement pier is required to be in contact with bedrock, and if the bedrock is deep, the depth of the cement pier buried underground is at least guaranteed to reach 1 meter.
