- TITLE:
- Wrapped-Lattice Cylindrical Arrays and Their Phase Modes,
Basic Theory
- AUTHORS:
- J. O. Coleman and W. M. Dorsey
- 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.
