Antenna for 'circular periscope' radio telescopes
Abstract
The paper examines the possibility of simplifying a variable-profile antenna by excluding the main reflector of radial displacement and azimuthal rotation from the reflecting elements. One inclination axis is preserved, and a secondary reflector is used with a focal line in the form of an evolvent from the horizontal section of the caustic surface of the main reflector, on which the primary feed, a linear array, is located.
