CEOS Instrument: Ka-band Radar INterferometer (KaRIN)

Instrument:Ka-band Radar INterferometer (KaRIN)
Agencies: NASA [Primary]
Mission: SWOT
Type:Radar altimeter
Description:Swath mapping radar altimeter that provides measurements for surface water
Spatial Resolution: Vertical resolution is 2cm
Swath Width: Vertical resolution is 2cm
Wavebands: N/A
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.
