Description

technical field [0001] The invention relates to the field of surface deformation monitoring, and more specifically, to a long-sequence automatic interferometric measurement system and method. Background technique [0002] The traditional technical means of surface deformation monitoring include leveling, GPS measurement, 3D laser scanning, and measuring robots. These traditional technical means have high measurement accuracy and sustainable monitoring, but the monitoring process is time-consuming and laborious and can only obtain deformation observation results at several independent points. The DInSAR (differential interferometry) and PSInSAR (permanent scatterer synthetic aperture radar interferometry) technologies are efficient and economical monitoring methods with high spatial resolution of images, and are capable of large-area high-density deformation monitoring. It has good application prospect and practical value in monitoring. [0003] DInSAR uses two interferomet...
