Abstract:
This paper presents a generalized description of the techniques for quantitative estimation of the state parameters of natural formations states from data of spectral, angular, and polarization measurements with the spaceborne scanning radiometers. This approach differs from earlier formulations of the problem by the separation of spectral reflectivity of layers, in its functional description of the outgoing radiation fields, into two parts. The first one describes interaction of optical radiation with the target volume under study while the second one represents the noise due to direct reflection of incident solar radiation from the upper boundary of the layer. As a result, the use of the proposed techniques enables one to represent each pixel of the image processed, earlier classified using standard procedures of image recognition and scene analysis, in terms of the state parameters obtained from data of sampling ground based measurements, these state parameters being characteristic of a particular class from the image.
