Ground-based differential interferometry synthetic aperture radar (GB-DInSAR) is a promising deformation measurement technology developed in the last 20 years. The GBDInSAR system is capable of sensing millimeter-scale deformations in the range of tens of meters to several kilometers from the target area in a continuous, all-weather environment. This article introduces in detail the basic principles of GB-DInSAR imaging, conventional signal models, deformationinversion algorithms, system working mode, existing typical systems, and application examples of high-precision deformation measurement in different scenarios. Moreover, this article systematically summarizes the latest research progress of GB-DInSAR technology and its future direction of development.
