CEOS Instrument: NASA Scatterometer




Instrument:NSCAT
Agency: NASA
Mission: ADEOS
Status:No longer operational
Type:Radar scatterometer
Description:Lost power on-orbit in 1997.
Spatial Resolution: N/A
Swath Width: N/A
Wavebands: N/A
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.
