Abstract

EM scattering from ocean surface are described using a generalized curvature expansion of the fields at an elevated non-perfect conducting surface. The new theory describes in general the scattering of EM waves from an undulated ocean surface, and reconstructs perfectly the case of Bragg scattering (Wright, 1966), and the case of perfect conducting surface (Elfouhaily et al., 1999). The formalism is applied to the case of backscattering, and expression from normalized radar cross section for different polarization combinations is given.
