Versatile Radar Applications
Earth Observation using spaceborne radar imagery
was strongly focussed on purposes in
the past. The TerraSAR-X Mission marks an
important step towards an increased use of
radar satellite data and derived geo-information
in a variety of commercial applications. These
bene t strongly from the unique TerraSAR-X
capabilities.
