Pattern synthesis and performance of conical arrays

Abstract

This paper extends a beam pattern synthesis algorithm based on the maximization of directivity subject to constraints on sidelobes, to a conformal array geometry. The expressions required for implementation of the algorithm are derived for an arbitrary set of elements and then evaluated for the specific case of an array of radiating slot elements on the surface of a right circular cone. The cone array geometry, chosen for its similarity to an aircraft or missile nosecone, is considered for several important performance parameters including scan volume, sidelobe control, and cross-polarization.
