A mask matching tiling optimization method for clustered phased arrays

A novel tiling optimization approach based on a mask matching strategy for the design of tiled phased arrays is here presented. Optimal complex coefficients, generating a power pattern satisfying some design constraints, are clustered into tiles of domino shape. The best tiling configuration fitting the desired requirements is obtained through an exhaustive search approach evaluating each solution with a mask matching strategy. A simple numerical example is reported to validate the proposed methodology.
