A simulation computer model of the optoelectronic path of the active-pulse visualization system is developed, which allows to analyze the influence of the atmospheric channel on the efficiency of the system as a whole. Most attention is paid to the effect of backscattering noise on the output image, as the most significant factor that reduces the contrast between the object and the background. The model provides an estimated-information support of the process of CT scan imaging optical-electronic systems. The basic mathematical relations underlying the model are given.
A software module, enabling approximate calculation of spectral atmospheric transmission coefficients within the wavelength range from near-ultraviolet to near-infrared emission, was developed. The present module provides computational and informational support for computer modeling process of optoelectronic systems (first of all, for geodetic purposes) when amount of source data on atmospheric conditions anticipated in modeling is limited. Principal mathematics taken as a basis of the model are specified.
