Earth Observation satellite.

Synthetic Aperture Radar (SAR) is a microwave imaging system. It has cloud-penetrating capabilities. It has day and night operational capabilities because it is an active system. Its ‘interferometric configuration’, Interferometric SAR or InSAR, allows accurate measurements of the radiation travel path. Measurements of travel path variations as a function of the satellite position and time of acquisition allow generation of Digital Elevation Models (DEM) and measurement o
