Abstract

A computational and experimental approach to clustering a compact active electronically scanned array has been considered for operation in a wide-angle electronic scanning sector. The proposed clustering has been treated not merely as a layout simplification but as an electrodynamically admissible replacement of individual channels by two-element radiating subsystems. An analytical synthesis procedure based on domino clusters and restrictions on local regularity of phase centers has been described. For a reference aperture with a diameter of about 10λ, a configuration of 97 two-element clusters has been obtained; after fitting into a circular aperture, it contains 86 controlled cluster channels. Full-wave modeling of the radiating element, horizontal and vertical clusters, and the complete array has been performed. The comparison of filled, clustered, and thinned arrays shows that the clustered array provides an intermediate gain level and an energy advantage over the thinned implementation in the main part of the scanning sector. Experimental measurements of prototypes confirm the preservation of sum and difference radiation patterns in the broadside mode.
