Non-redundant antenna configurations on a 2-d interferometer aperture completely covering central domains in the frequency space

Abstract

A regular method for building a non-redundant multi-element 2-D array configuration is suggested. The method is based on using sequences of a special type – planar difference sets. Here, it is applied for constructing a mathematical model of a radio interfe- rometer that ensures the complete coverage of the central domain in the frequency space. The non-redundant configurations satisfying this condition, with the numbers of elements up to 38, are presented.
