ERS-1/2 Synthetic Aperture Radar Wave Fast Delivers ProductEntry ID: ERS.SWM.UWA
Abstract: The AMI combines two separate functions: the SAR
and the Wind Scatterometer. The SAR can operate in two
modes: Image Mode and Wave Mode.
This product is generated with data from the SAR
operating in Wave Mode and is produced as monthly datasets.
Wave Mode operation of the SAR provides 5 km x 6 km images
at intervals of 200 km along ... track. This product provides
the SAR wave power spectra in polar coordinates.
Because the data rate
is relatively low, onboard data storage is possible, and
there is a global sampling of wave spectra.
The product is received at Nominated Centres within 3
hours of acquisition via the ESA Fast Delivery System.
Imagette area: 5 x 6 km
Spectrum size: 12 angular sectors each of 15 degree
representing range 0 to 180 degree; power given in 8 bits
for each spatial wavelength in range 65.8 m to 658.0 m
Imagette volume: 964 bytes
Product volume per month/cycle: ~ 65 Mbytes
