The invention discloses a space-borne / ground-based InSAR dual-purpose artificial corner reflector, which is characterized in that it comprises a vertical trihedral corner reflector for space-borne InSAR measurement, a connecting rod, a monitoring pier, a universal coupling, and a foundation A vertical trihedral corner reflector for InSAR measurement, the vertical trihedral corner reflector for spaceborne InSAR measurement is arranged on the top of the monitoring podium, and the vertical trihedral corner reflector for ground-based InSAR measurement is arranged on the monitoring On the upper side of the podium, the vertical trihedral corner reflector for spaceborne InSAR measurement is fixedly connected to the top of the monitoring podium through the connecting rod, and the vertical trihedral corner reflector for ground-based InSAR measurement is passed through the top of the monitoring podium. The universal coupling is fixedly connected to the upper side of the monitoring podium. The present invention can acquire multi-directional deformation data at the position of the artificial angular reflector synchronously or approximately synchronously, give full play to the respective advantages of space-borne InSAR and ground-based InSAR technologies, and realize high-spatial-resolution space-borne InSAR and high-time-resolution ground-based Air-to-ground joint measurement of InSAR.
Description
technical field [0001] The invention relates to a spaceborne / ground-based InSAR dual-purpose artificial angle reflector, which belongs to the technical field of synthetic aperture radar interferometry. Background technique [0002] Synthetic aperture radar interferometry (Interferometric Synthetic Aperture Radar, InSAR) is a newly developed space earth observation technology, which is the product of the combination of traditional SAR remote sensing technology and radio astronomy interferometry technology. It uses radar to transmit microwaves to the target area, and then receives the echo reflected by the target to obtain the SAR complex image pair imaged in the same target area. If there is a coherent condition between the complex image pairs, the SAR complex image pair can be conjugated and multiplied to obtain the interferogram , according to the phase value of the interferogram, the distance difference of the microwave in the two imaging is obtained, so as to calculate th...
