Therefore, deformation monitoring during the construction process is particularly important. It can be combined with Corner reflectors and remote sensing deformation technology are used to monitor deformation during construction.
角反射器是由若干个相互垂直的金属板或其他导电材料平面构成的电波反射装置,当有一条光线入射时,经相互垂直的两块平面镜反射后,能够沿与入射光线平行的方向反射回去。空间上沿任意方向射向角反射器的光线均可经两次或最多三次反射后沿原来的入射方向的反方向射出。当雷达电磁波扫描到三角反射器后,电磁波会在金属角上产生折射放大,在雷达的屏幕上出现强烈的回波目标,角反射器常被用来测距、道路指引等。The corner reflector is a radio wave reflection device composed of several mutually perpendicular metal plates or other conductive material planes. When a light is incident, it can be reflected back in a direction parallel to the incident light after being reflected by two plane mirrors perpendicular to each other. . The light rays incident on the corner reflector in any direction in space can be reflected twice or at most three times, and then emitted along the direction opposite to the original incident direction. When the radar electromagnetic wave scans the triangular reflector, the electromagnetic wave will be refracted and amplified on the metal corner, and a strong echo target will appear on the radar screen. The corner reflector is often used for distance measurement and road guidance.

Remote sensing deformation monitoring technology includes satellite remote sensing deformation monitoring technology, ground-based radar remote sensing deformation monitoring technology and UAV remote sensing deformation monitoring technology. The remote sensing deformation monitoring technology has different incident directions and incident angles of remote sensing signals, and most of the existing corner reflectors are unidirectional vertical trihedral structures, and it is difficult to adjust the vertical angle, so it is impossible to simultaneously receive different incident angles and different incident directions independently. remote sensing signal.
