Abstract : This report describes the progress in the analysis, development, and evaluation of a subreflector array technique. This array is used with a parabolic reflector and feed horn to reduce antenna noise temperature while providing increased antenna efficiency. The areas discussed in this report include: subreflector array diffraction-pattern performance and design calculations, array zoning, surface inter-action effects and demonstration model design.
