InSAR (Interferometric Synthetic Aperture Radar)

Interferometric Synthetic Aperture Radar (InSAR) is a remote sensing technology that uses radar signals from satellites to measure ground movement and changes in the Earth's surface. By capturing multiple images of the same area at different times and comparing them, InSAR detects subtle shifts—such as those caused by earthquakes, landslides, or subsidence. The technique creates detailed maps that show how much and in what direction the ground has moved, providing valuable information for natural disaster monitoring, infrastructure health assessment, and environmental studies. This approach enhances our understanding of geological processes and helps in effective planning and response efforts.
