Abstract
A technique has been developed and a calculation has been made of the irradiance of the entrance pupil of a ground-based optoelectronic system (OES) from a cylindrical space object illuminated by the Sun at night. The results of calculating the minimum irradiance and corresponding stellar magnitude at the input pupil of the OES are presented with a signal-to-noise ratio at the output of the photodetector matrix with a current equal to 7 in the wavelength range of 0.45 ÷ 0.85 mm. The dependence of the signal-to-noise ratio on the distance to the space object for its three different sizes is constructed. The program ROSN-1 was developed and its control panel was presented for calculating the characteristics of ÷ 0.85 mm was presented, and the possibilities of this program were explained.
