Calculation of the RATAN-600 radiotelescope patterns with account for aberrations.
Abstract
The paper presents results of radiation-pattern calculations for the RATAN-600 radio telescope in the presence of aberrations associated with the feed's position outside the focus of the main reflector. Equations for calculating the radiation patterns are derived, and results of computer-aided calculations are given. The results obtained relate to the main operating mode of the radio telescope, when only some reflector elements are used simultaneously.
