Abstract :
The results of polarimetric microwave measurements of thermal emission from a water surface with artificial periodic structure are presented. The structure in a water tank was produced by a set of parallel threads raised a little over a surface. The measurements of the three Stokes parameters of the emission were carried out with the Ka-band polarimeter. The experimental setup allowed measurements over a wide range of elevation (from near-nadir to 70 degrees) and azimuth (over 300 degrees) angles. The experimental data show the existence of the resonant peak in the Stokes parameters predicted by the model. This result is evidence of the important roˆle the short gravity-capillary waves play in the sea-surface polarized microwave emission
