Abstract

Situation when Point Spread Function (PSF) of the device is indefinite or it is roughly appreciated takes place almost always. In an optical wave range PSF (optics + atmosphere) is frequently indefinite, because of an indefinite conditions of scattering and turbulence of an atmosphere. The antenna pattern or PSF of radio telescopes cannot be measured. The near zone of the radio telescopes is so big that it does not allow to measure the antenna pattern or PSF by the ground based methods. The methods of evaluation of PSF on details of the images are considered in the repot. The received estimation of PSF is used for the solution of task (compensation of PSF distortions) super-resolution.
