Minimum redundancy linear arrays for a large number of antennas

Abstract

A linear array that achieves maximum resolution for a given number of antennas is advantageous in earth‐rotation aperture synthesis. This type of array is called a minimum redundancy linear array; it is obtained by reducing redundant spacings present in the array. Various methods are examined to find optimum arrays for a large number of antennas. From the systematic analysis of regular patterns in these arrays, a possibility of generalizing optimum arrays is suggested. Optimum configurations could also be used for distributing stations in an aperture synthesis array.
