The analysis of intensity variations of reflected radiation above a nonhomogeneous underlying surface with the aid of spatial-frequency characteristics
Abstract
The variations in the intensity of reflected solar radiation related to horizontal variations of the albedo of an underlying surface are considered. In linear approximation, the variations are determined by means of nonstandardized amplitude-frequency A and phase-frequency phi characteristics of the atmosphere. A detailed description is given of the various steps involved in the derivation of the mathematical relations describing the considered intensity variations of the reflected radiation. Examples of a numerical analysis of intensity variations for a number of cases are presented with the aid of graphs.
