Interferometric Synthetic Aperture Radar (INSAR) is a technology used to measure ground deformation with high precision over large areas. It uses the phase difference between two or more radar images acquired in the same area to detect subtle changes in surface elevation. INSAR is particularly useful for monitoring and studying geological phenomena such as earthquakes, volcanic activity, landslides and subsidence. By analyzing the interferometric phase, INSAR can create detailed maps of ground movement, providing valuable information for risk assessment, urban planning and environmental monitoring.
Interferometric synthetic aperture radar (INSAR) is widely used for a range of applications related to Earth observation and geophysical monitoring. It allows scientists and researchers to measure and monitor changes in the Earth’s surface with high spatial and temporal resolution. INSAR is employed to study terrain characteristics, map land cover and land use, monitor forest biomass, and assess environmental changes. Additionally, it plays a crucial role in urban planning, infrastructure monitoring (like bridges and dams), and disaster management by providing accurate and timely information on ground movements and deformations over large areas.
Synthetic aperture radar (SAR) satellites are used for a variety of purposes related to Earth observation, environmental monitoring, and national security. SAR satellites work by transmitting microwave pulses toward the Earth’s surface and recording reflections bounced off objects and terrain features. The main advantage of SAR satellites is their ability to image the Earth’s surface in all weather conditions and during day and night. SAR data is used for applications such as monitoring sea ice and ocean dynamics, mapping deforestation and land cover changes, tracking agricultural activities, detecting oil spills and support for disaster response efforts. SAR satellites provide valuable information for scientific research, resource management and decision-making processes on a global scale.
