Changes in sea Surface Roughness are usually associated with a change in the sea Surface wind field.
With various Radar frequencies, resolutions, and modes of polariz.
A number of features on the sea Surface associated with changes in Roughness can be Observed by synthetic aperture Radar (SAR) because of the change in Bragg backscatter of the Radar signal by damping of the resonant ocean capillary waves.
This interaction has been exploited to measure sea Surface wind speed by scatterometry.
