Abstract

Wide usage of new approaches in radiovision for the sake of radio astronomical investigation is expected as they can fix image independently of the atmosphere state. New ranges of radiation registration promise to show new processes and phenomena in astronomy. Existing Sun radiovision system doesn't give possibility to resolve the details of the processes on the Sun fine structure. Near zone of the radiotelescope is so big that it doesn't allow to measure Sun radiovision system Point Spread Function (PSF) by the ground based methods. By the other words, it's impossible to estimate minimal point object (PSF) that could be seen on the Sun by ground based methods. The task of radiovision system PSF estimation was solved valuing the Sun's edge in the assumption of PSF circular symmetry. In the paper the possibilities of developed dialog complex of complicated Sun's radio observing system modeling with subsequent antenna pattern distortions compensation by linear and nonlinear methods.
