  • Satellites observing and measuring the Earth’s surface with electromagnetic waves are subject to atmospheric path delays. Atmospheric effects on radar signal propagation modify the signal velocity and direction and can be considered by simple modelling. In order to increase the geolocation accuracy of spaceborne SAR applications we developed a software tool that accounts for atmospheric path delays. Well-calibrated spaceborne ENVISAT-ASAR data are used to investigate improvements to knowledge… CONTINUE READING
