Influence of antenna pattern distortions on the quality of solar radio images obtained with the radiotelescope RT-2

The influence of antenna pattern distortions of the radiotelescope on the quality of radio images of the Sun is analysed in this report. The mathematical simulation of effects of distortion is conducted and the valid asymmetry of a level of the first side lobes of the antenna pattern is defined. The model of the antenna pattern for the radiotelescope RT-2 is selected. This model was used in the procedure of image reconstruction.
