Wrapped-Lattice Cylindrical Arrays and Their Phase Modes, Basic Theory

Abstract

Taylor's 1952 approach to steering a uniform circular array (UCA) used a discrete-Fourier-transform (DFT) of the element outputs to create signals now routinely termed phase modes. This work derives an analogous phase-mode representation and steering approach for a cylindrical array in which elements are nominally located on a 2D lattice, which need not be separable, wrapped around the cylinder. The DFT becomes a generalized DFT on a lattice with the DFT sum indexed on a family of coset representatives. This is preliminary work and does not yet include computational simulation or experimental results.
