A Multiple-Beam Microwave Antenna Based on the Principle of the Mills Cross.
Abstract
A study has been carried out to determine the feasibility of various antenna configurations for a proposed satellite mission to profile the surface temperature of the ocean using a passive microwave radiometer. Specifically, a static, multiple-beam microwave antenna utilizing a phase-switched Mills cross as its basic element is proposed and analyzed in detail. Although the Mills cross configuration does not completely meet the specified requirements of this particular application, its analysis does provide a necessary frame of reference for assessing its usefulness in general, and for establishing its features and drawbacks relative to alternative antenna configurations. It also serves as an illustrative example of some of the design tradeoffs and problems that are encountered in trying to map the earth's surface from a space platform. (Author)
