SCAT  

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.
