Abstract
The article develops the technique for predicting the quality of cosmic optoelectronic images of the visible range of waves. This technique takes into account the indicators that flow to the final quality of the image, which greatly increases the informativeness of the original images. During the development of the methodology, the following main factors influencing the quality of cosmic optoelectronic images were designed: the magnitude of the solar radiation flux; dispersion and absorption of light in the atmosphere; reflection from objects on the Earth's surface; the technical characteristics of the optoelectronic system itself. To implement the methodology, a program has been developed, the main basic elements of which are mathematical models of the elements of the system of optoelectronic space imagery.
