Abstract

The paper considers the design of minimum phase discrete linear arrays. The paper introduces recent advances for the design of minimum phase Finite Impulse Response filters, as applied to the design of minimum phase linear arrays. The minimum phase linear array is demonstrated to require the least number of elements of all linear arrays that are able to achieve a given magnitude pattern specification. Three example designs are presented and compared to results from the literature.
