Abstract

The composite surface scattering model is applied to rough surfaces derived from measurements of a spilling-breaker wave. Comparison with moment method calculations show that the model can be used to accurately predict the scattering although the surface is multi-valued at many times due to an electromagnetically small bore feature. Moment method calculations of the scattering from an additional breaking wave profile history support the theory that “fast scatterers” result from quasi-specular reflection from very steep surface features
