The scattering fields of 2-D sea fractal surface with finite conductivity illuminated by ellipse polarization wave. Part two. Scattering matrix and numerical results

The scattering fields of 2D sea fractal surface with finite conductivity illuminated by ellipse polarization wave in Cartesian coordinate system have been evaluated in part one. We derive here the relation expression between scattering fields and d illumination fields with 3×3 matrix in local coordinate system. The radar cross section (RCS) on different polarization is obtained and numerically simulated. It shows that the results of our scattering model are in agreement with those of other literatures for some special case. We get some conclusions: (1) valued of radar cross sections of cross polarization (VH and HV) are less than those of co-polarization (VV and HH) but cannot be neglected; (2) when the incidence angle θ₁, and the scattering angle θ₂ are determined, the angle of the scattering plane out of the illuminating plane θ₃ varies from 0° to 180°, different relations among θ₁, θ₂ and θ₃ in different relationships between σ_vs,vt⁰, σ_hδ,h_i⁰ and σ_vδ,h_i⁰, σ_hδ,v_i⁰ are derived, we can use these inequalities to predict the critical angle θ₃ where the relation between RCS of VV and HH,VH and HV polarization will exchange, respectively; (3) the effects of depolarization can be neglected though we derived the expressions for them.
