On the orthogonal nonuniform synthesis from a set of uniform linear arrays

Synthesis of uniform linear arrays by using the orthogonal method is presented. Composing functions similar to that of Woodward-Lawson technique are used. In Woodward-Lawson technique, sampling of the desired pattern is made. In this letter, instead of sampling, the orthogonal method is applied. The number of composing functions can be the same as or different than the elements of the arrays. Also, the progressive phase of each function can be derived in several ways. Numerical examples for the synthesis of different array patterns are presented, and the results show the usefulness of the method.
