Scattering by composite rough surfaces

Abstract

The paper investigates scattering by surfaces generated by a superposition of several random processes (such as swell plus sea plus ripple). Explicit expressions for the dependence of the mean scattered power on the scattering geometry and wavelength in terms of the scale roughness and the rms slope of the individual components are derived for bistatic scattering. The special case of backscattering is analyzed more closely, and the importance of the small structure of the surface is demonstrated.
