Emission and Reflection from Anisotropic Random Rough Surfaces.
Abstract
A geometrical-optics theory of emission and scattering from anisotropic random rough surfaces is developed. A complete ray treatment is provided in the sense that multiple-scatter and bistatic shadowing effects are included in a consistent manner for a general two-dimensionally rough surface. It is also shown that, in the context of this theory, both upper and lower bounds exist to the effects of surface roughness on the emissivity. A numerical calculation of the emissivity for a perfect conductor provides a check on the theory against a known result, and the scattering theory is shown to conserve energy to a relatively high degree of approximation when double-scatter effects are included. Predictions of the emission theory for the thermal microwave emission from the sea surface are compared with the results of earlier theories. (Author)
