Abstract

In this paper, we represent numerical results which, validate our former work on the hydrodynamic effect (nonlinear) produced by breaking waves in EM bistatic scattering coefficients. We calculated the scattering coefficient σ_HH of breaking waves in bi-static configurations as a function of time. Then, in this paper we represent the first experimental measurements, which have been carried out in X-band in our anechoic chamber (E³I²-EA3876- laboratory of Ensta bretagne); of the breaking waves profiles. In this work, we consider the sea surface as a perfect conductor rough surface.
