The algorithm of the sidelobe level optimization for the dual shaped symmetric reflector antenna with the aperture diameter D20 lambda is presented. It is based on the method of the far-field pattern estimation by the aperture distribution. maximal aperture efficiency is the criterion of the aperture distribution optimization on the condition that the far-field pattern estimation answers to recommendations ITU-R. Optimization parameters are defined by the function of the aperture distribution that is described a analytical function with shadow area at the center aperture, uniform are and transition regions.
