TLDR
In this article, the scattering and reflecting properties of surfaces which are perfectly conducting but which have random irregularities are investigated in a statistical manner, where the surface is assumed to be not too precipitous.Abstract:
The scattering and reflecting properties of surfaces which are perfectly conducting but which have random irregularities are investigated in a statistical manner. The surface is assumed to be not too precipitous. With a statistical model for the surface, the scattering of light by a disturbed water surface is considered, and the method is used to calculate the amount of sea clutter observed in centrimetric radar. A comparison with some observations is made.read more

A reflectance model for computer graphics
TL;DR: In this paper, the spectral energy distribution of the reflected light from an object made of a specific real material is obtained and a procedure for accurately reproducing the color associated with the spectrum is discussed.

Surface reflection: physical and geometrical perspectives
TL;DR: In this paper, the effect of surface roughness on the three primary components of a reflectance model is analyzed in detail, and the conditions that determine the validity of the model are clearly stated.

Experimental study of scattering from characterized random surfaces
TL;DR: In this article, an experimental investigation of light scattering from random rough surfaces is described, whose height fluctuations approximately follow Gaussian statistics, are fabricated in photoresist with a metal overcoating, and the effects of multiple scattering are shown to be consistent with the major features of the observations.
Proceedings ArticleDOI
A reflectance model for computer graphics
TL;DR: A new reflectance model for rendering computer synthesized images that describes the directional distribution of the reflected light and a color shift that occurs as the reflectance changes with incidence angle is presented.

Propagation of Short Radio Waves
TL;DR: The Lorentz reciprocity theorem to scattering is applied to scattering in a horizontally stratified atmosphere and results in coherent and incoherent scattering from assemblies of scatterers.
