DInSAR (Differential InSAR)

Differential Interferometric Synthetic Aperture Radar (DInSAR) is a remote sensing technique used to measure ground movement with high precision. It works by capturing radar images of the Earth's surface at different times, then comparing the phase differences between these images to detect tiny changes in elevation or displacement. This allows scientists to monitor phenomena like land subsidence, volcanic activity, or earthquake-related shifts. Essentially, DInSAR provides detailed, timely information on how the ground is moving, which is valuable for hazard assessment, infrastructure monitoring, and environmental studies.
