Abstract

Abstract The radiation pattern of a conformal, quasi-uniform distribution of elements, each containing a radiating aperture, mixer and possible other active and passive components, is controlled by controlling the phase-amplitude characteristics of signals applied to the elemental mixers. The phase-amplitude characteristics of the control signals are derived from a scaled array wherein individual elements are arranged in accordance with those of the operational conformal array. The scaled system is illuminated by an electromagnetic or acoustic beam having the desired radiation pattern and the characteristics of the elemental signal within the elements of the scaled array control the radiation pattern of the conformal array in the desired manner.
