Abstract :
The purpose of this paper is to provide readers an easy set of equations and design parameters to generate Schwarzschild dual-reflector systems. We consider the geometry of a Schwarzschild dual-reflector system, consisting of two rotationally symmetric reflectors, which form an aplanatic system that fulfills the Abbe sine condition. This dual-reflector system ensures freedom from spherical and primary coma aberrations when the feed horn is displaced from the axis of symmetry. This is a useful property for beam-scanning or multibeam applications
