INVESTIGATION OF A MULTIPLE BEAM SCANNING CIRCULAR ARRAY,
Abstract
One phase of a theoretical and experimental pro gram directed toward the development of a multi ple-beam or steerable cylindrical array is de scribed. The object was to develop a cylindrical array which could provide high resolution cover age over 360 degrees of azimuth angle. The basic intent of the program was to theoretically ana lyze, and experimentally verify, an RSi con ceived technique for reducing the problem of processing the antenna elements of cylindrical arrays to one analogous to the element processing of linear arrays. This equating of the array processes allows all of the techniques developed for linear arrays to be applied to cylindrical arrays. A partial listing of these processing techniques would include the synthesis of any desired far-field radiation patterns, the scanning of the synthesized patterns, or the multiple beaming of these synthesized patterns. Hence, the cylindrical array may be used to provide steerable or multiple beams over 360 degrees in a horizon plane by employing the same scanning and multiple-beam processing developed for linear arrays. The distinction, of course, is that linear arrays, at the extreme, are limited to less than 120 degrees of coverage. (Author)
