CEOS Instrument: SAR Interferometer Radar Altimeter

Agency: ESA
Missions: CryoSat
Type:Radar altimeter
Description:Marine ice and terrestrial ice sheet thickness measurement
Spatial Resolution: Range resolution 45 cm, along-track resolution 250 m
Swath Width: Footprint 15 km
Wavebands: Microwave: 13.575 GHz (Ku-Band)
Technology: Radar altimeter
Description: Nadir-viewing radar for very accurate ranging measurement between satellite and surface. The spread of echoes provides information on significant wave height, the intensity on the wind speed, the multi-temporal analysis the ocean dynamic topography and the geoid. The instantaneous field of view is ~ 25 km and moves along track. The radar altimeter operates in Ku-band (~ 13 GHz) with the support of C-band (~ 5 GHz) for correction from ionospheric rotation; and is associated to a nadir-pointing MW radiometer for water vapour correction. Applicable only in LEO.
