Geometrical optics shaping of large dual offset reflectors for contoured beam radiation

Abstract

It is shown that simple ray tracing techniques can be used to shape either the subreflector or the main reflector of a dual offset reflector system to realize prescribed phase distribution at the aperture. Main reflector shaping introduces negligible amplitude distortion when the reflector diameter, in terms of wavelengths, is large. Subreflector shaping… (More)
