Synthetic Aperture Radars offer the possibility of earth imaging notwithstanding night or weather
conditions. As the penetration of the electromagnetic waves in arid terrain could reach meters,
SAR instruments can reveal paleo rivers in a desert. Also, SAR’s can measure travel times and
thus distances, generating not only good digital elevation models, but also terrain models as the
vegetation canopy can be penetrated. Finally, if the radar targets are temporally stable, then
their millimetric motion can be measured allowing co-seismic motion studies, inflation - deflation
of gas storage reservoirs, dams motion due to water filling, etc.
Numerous public and private constellations of these sensors are nowadays available and their
use is more and more common.
