Small grazing angle radar scattering from a breaking water wave:Demonstration of Brewster angle damping

摘要

The small-grazing-angle backscattering from breaking water wavesis examined using a hybrid MM/GTD numerical technique. The calculatedscattering shows that Brewster angle damping strongly limits themultipath scattering from breaking plumes at vertical polarization,yielding HH/VV scattering ratios of up to 15 dB. Comparison withexperimentally measured scattering from a small breaking wavedemonstrates the validity of the numerical approach
