Abstract
Disclosed is a means for synthesizing many different antenna patterns with different beamwidths and elliptical symmetries, being derived from a common data set corresponding to a planar cut or slice of an arbitrary antenna pattern which is stored in an addressable memory such as a programmable read only memory (PROM). A pattern surface or envelope is modeled by an algorithm which takes generated azimuth and elevation values simulating a desired scanning motion from which a memory address is produced according to a predetermined mathematical relationship including factors which determine the degree of ellipticity as well as the beamwidth relative to the stored planar cut of the arbitrary antenna pattern.
