The invention discloses an automatic satellite-finding corner reflector, which comprises a corner reflector. The corner reflector is mounted on a three-dimensional pan-tilt. The three-dimensional pan-tilt is used for adjusting the direction of the corner reflector. The corner reflector is provided with an electronic compass for sensing the pointing direction of the corner reflector. The electroniccompass and the three-dimensional pan-tilt are connected with a control module. The control module is connected with a space-based internet-of-thing receiving module and a GPS / Beidou positioning module. The space-based internet-of-thing receiving module receives a satellite-finding instruction forwarded by a space-based internet of things, and sends the instruction to the control module; and thecontrol module calculates adjustment direction and angle of the corner reflector according to the received satellite-finding instruction and the current pointing direction of the corner reflector, andcontrols the three-dimensional pan-tilt to rotate to adjust the direction of the corner reflector so as to enable the corner reflector to face to a satellite. The automatic satellite-finding corner reflector can work in remote areas without coverage of a ground communication network, and provides manual control points for calibration, correction, positioning and registering of various space-bornesynthetic aperture radars in remote areas.
Description
technical field [0001] The invention relates to a corner reflector, in particular to a corner reflector which can be used for automatic star finding in areas without communication network coverage. Background technique [0002] Synthetic aperture radar is a new remote sensing technology that has developed rapidly in recent years. The correction, positioning and registration of synthetic aperture radar images require the cooperation of ground scalers. Corner reflectors are simple and efficient artificial scalers that have been widely used in synthetic aperture radars. The pointing of traditional corner reflectors is fixed. Since there are many spaceborne synthetic aperture radars currently in orbit, and more spaceborne synthetic aperture radars may be launched in the future, a corner reflector that can be applied to a variety of satellites is needed , that is to say, the corner reflector is required to be able to automatically find stars according to the instructions, and ad...
