Effect of a Perturbed Wavefront on the Power Pattern of an Array.

Abstract

A horizontal, geometrically spaced array, is under consideration for implantment in the Bermuda area. The problem is to obtain the pattern of the array for a perturbed wavefront. The first solution to this problem was obtained by Stocklin. Stocklin considered a random phase at each receiver, that was Gaussian distributed and independent for receiver to receiver. This model was later extended by Berman and Berman who considered correlated phases. Experimental values of phase (time delay) spreads and correlation of phases was obtained by Worley. The purpose of this memorandum is to apply some of the experimental values to the theoretical equation and to find the effects on a possible sub-array configuration of the proposed array. (Author)
