Potentialities of technical means of observation that realize and receive images for distinguishing objects from their spectral characte-ristics of reflection (radiation) are considered.
On the basis of optimal image processing algorithms in a wide range of wavelengths, provided that the functions of the spatial-frequency distribution of objects are separable, analytical relations are obtained for the square of the object detection parameter by their spectral composition.
The analysis of the separate influence of spatial and spectral coefficients of image correlation on the possibility of image differentiation in terms of space and spectrum carried out. An analysis of the spatial effect of the spatial and spectral coefficients of image correlation on the possibility of image differentiation in terms of space and spectrum is analyzed. It is shown that different objects are possible only with respect to the spectral composition and part of the difference spatial-frequency spectrum, which are transmitted by the transfer function of technical observation means. The energy equivalence of the spectral contrasts is the spectral contrasts is determined, which determine the potential capabilities of modern observational means for distinguishing objects by their spectral composition.
The practical significance of results obtained is that the proposed approach opens the way for the development of remote observation methods based on video-spectral survey and the validations of the parameters of video spectrometers taking into account the spatial-frequency characteristics of the objects under study.
