A study of random pattern processing techniques has been conducted to explore the utility of angular dispersion-compression antenna techniques for achieving multidimensional resolution, and hiding of the transmitted signal. Three basic areas of study are reported on 1 creating of an angularly dispersed field pattern with good correlation properties and compatibility with hiding, 2 multidimensional resolution concepts, and 3 multidimensional optical processing. Results of coding theory are reviewed, and it is found that Legendre binary and Frank-Heimiller polyphase codes are suitable for dispersed pattern specification. Computer programs are described with implement an approximate least squares synthesis of ring arrays with dispersed patterns that conform to binary sequences. Results are given for a Legendre code of length 31.
