text: Purpose:	Sea-surface vector wind.
Short description:	Rotating Fan-beam Scatterometer (RFSCAT). Ku-band (13.256 GHz), dual polarisation (HH and VV).
Scanning Technique:	Combining the fan-pencil concept (such as, e.g., ASCAT) and the rotating concept (such as, e.g., WindSat). Rotating speed: 5.7 rpm; swath 1000 km. Duty cycle 15-35 %.
Resolution:	High quality data: 50 km. Basic sampling: 10 km.
Coverage / Cycle:	Global in one week.
Data Rate:	220 kbps

update Definition (Remote Sensing Laboratory / Center for Space Science and Applied Research / Chinese Academy of Sciences), Beijing, China. SCAT will be the first RFSCAT (Rotating Fan-beam Scatterometer) pointing at medium incidence angles (26° to 46°) with a dual antenna system; it is flown on a spacecraft for global ocean vector wind observations.

SCAT is a Ku-band RFSCAT with HH and VV polarizations. The expected ocean wind vector retrieval performance is as follows (with 50 km OSVW resolution):

• Wind speed accuracy: 2 m/s or 10% (larger) within the 4~24 m/s wind speed range

• Wind direction accuracy: ±20º within the 360º wind direction range

• Ground geolocation accuracy OSVW resolution cells: < 5 km.);
