Abstract :
The small-grazing-angle backscattering from breaking water waves is examined using a hybrid MM/GTD numerical technique. The calculated scattering shows that Brewster angle damping strongly limits the multipath scattering from breaking plumes at vertical polarization, yielding HH/VV scattering ratios of up to 15 dB. Comparison with experimentally measured scattering from a small breaking wave demonstrates the validity of the numerical approach
