Abstract :
The inherent spherical aberration of a spherical reflector antenna is corrected by using an auxiliary Gregorian reflector feed system that rotates about the center of curvature of the reflector. Tests at both 
- and 
-band frequencies demonstrate feasibility of the design for wide-angle scanning.
