Abstract

In this article, we carried out a preliminary study on the hydrodynamic effect (non-linear) produced by the breaking of a coastal wave on the scattering coefficient (in horizontal and vertical polarization) in the bi-static configuration (forward propagation). We calculated in X-band (10 GHz) σ_HH and σ_VV of a series of oceanic surfaces (different phases of construction of a breaking wave (θ_i = -20°) then we studied the different characteristics for each scattering coefficients. In this first study we considered that the maritime surface is the perfect conductor.
