Optical simulation is used to investigate the radiation pattern of the Ratan-600 telescope in the presence of aberrations associated with displacement of the feed from the focus. The aberration is simulated using specially prepared filters, realized in the form of synthetic holograms. A formula is given for calculating these filters along with an expression for the radiation pattern of the telescope in the presence of aberrations.
