Abstract

Polyomino-based arrays allow to efficiently exploit the available array area with a regular element lattice, yet exhibit a non-uniform distribution of their phase centers, leading to superior electronic scanning capabilities. Yet polyomino arrays are usually implemented via polyomino of equal order, leading to uniform amplitude distribution and poor side lobe levels. In this contribution, a tiling of polyominoes of different order is proposed to attain at the same time good scanning characteristics and side lobe level.
