Abstract

Optimal algorithms of imaging extensive sources of intrinsic radioheat non-coherent radiation, and their electrophysical parameters and statistical characteristics (such as brightness and absolute temperatures, permittivity, means- square height and correlation radius of surface microirregularities, oil skin thickness etc.) estimation are studied in the case of constant surface parameters as well as in the case when values of parameters depend on surface coordinates. The peculiarity of these algorithms is that they are synthesized for a common case of wide- or superwide-band radiation detecting when the condition of spatial-temporal narrowbandness (quasi-monochromatic approximation) is broken. The algorithms are produced in the frame of maximum likelihood and maximum a posteriori probability density methods. indeterminacy functions of measuring systems are studied. Used mathematical apparatus is based on proposed transforms, that generalize the Fourier's, Laplace's and Fresnel's ones, as well as on proved theorems that extend the Van Zittert-Zernike theorem to the case of wide-band and superwide-band fields analysis.
