Azimuthal and polarization parameters of the sea-surface microwave emission measured from a pier

The paper presents the results of sea-surface microwave brightness measurements carried out from a pier in 1999 and 2000. The brightness dependence on surface wind speed was investigated over wide range of azimuth and elevation angles. It was noted that under unstable wind conditions microwave brightness contrasts correlate with wind speed. When the wind speed decreased, however, significant delay in brightness decreasing was observed. This may be treated as an evidence of cascade mechanism In the energy transfer from long waves to short gravity-capillary waves.
