## haracteristics of RATAN-600 radiotelescope in the operational mode with a tertiary mirror at the wavelength 8 mm

Transactions of IAA RAS, issue 24, 62–69 (2012)

Keywords: an antenna with a variable surface profile, geometrical and optics model, diffraction model, antenna system, feed array receiver

### Abstract

We have developed geometrical optics and diffraction models of the RATAN-600 antenna system "South sector + Flat reflector" with a tertiary mirror. We present the results of study of its characteristics. Introducing the auxiliary mirror allows expanding image field size of the antenna system, thus using feed array receiver. Spline-profile smooth-walled horns for 8 mm wavelength were designed and manufactured in order to use them in the modified antenna system.
