CEOS Instrument: Scatterometer




Instrument:Scatterometer
Agencies: ROSHYDROMET [Primary]
 ROSKOSMOS
Mission: Meteor-M N3
Status:Approved
Type:Radar scatterometer
Description:Ocean surface wind measurements
Spatial Resolution: 25 km
Swath Width: 1800 km
Wavebands: Ku-band
Technology: Radar scatterometer
Description: Radar with very accurate calibration, to observe an earth’s spot from several directions (ahead, after, aside) and measure differential backscatter coefficients (s0) from sea capillary waves (thus observing surface wind). On land, the s0 are correlated with soil moisture. Two concepts exist: electronic scanning, side looking, exploiting C-band (~ 5 GHz); and conical scanning, exploiting Ku-band (~ 13 GHz). The resolution is typically 25-50 km, the swath 1100-1500 km. Applicable only in LEO.
