Preferred term

KaRIn  

Definition

  • Ocean and surface water levels are measured over a 120-km (75-mi) wide swath with a ~20 km (~12 mi) gap along nadir using a Ka-band radar interferometer. KaRIn (Ka-band Radar Interferometer) has two antennas separated by a 10-meter boom. Radar pulses are transmitted by one antenna and received by both for interferometry, creating two parallel swaths of data. More information: https://swot.jpl.nasa.gov/mission/flight-systems/ (en)

KaRIn (Ka-band Radar Interferometer) has been developed by JPL on the legacy of the American Shuttle Radar Topography Mission (SRTM) and Wide Swath Ocean Altimeter (WSOA) instruments. It has two transmitting/receiving antennas operating simultaneously and located at either end of a 10 m boom. It is this exact configuration that enables the interferometric measurement needed for the prescribed accuracy, spatial resolution and wide swath of the SWOT mission.
