CEOS Instrument: SAR Radar Altimeter

Agencies: ESA [Primary]
Missions: Sentinel-3 A
 Sentinel-3 B
 Sentinel-3 C
Type:Radar altimeter
Description:Marine and land services
Spatial Resolution: 300 m
Swath Width: Profiling
Wavebands: Dual freq radar altimeter, Ku-band, C-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.
