LOW NOISE ANTENNA TECHNIQUES

Abstract

The report describes the progress made in analysis, development and evaluation of a subreflector array illumination control technique. The subreflector array technique is used in conjunction with a parabolic reflector and feed horn to reduce antenna noise temperature while providing increased antenna efficiency. This report includes the results of a model test program which indicates a model efficiency of 68 percent and a noise temperature of 27 degrees kelvin over a 5 percent S-band frequency range. Discussion also includes a focal fed lens array design and application to conical scanning and monopulse systems.
