Equivalent linear array approach to array pattern synthesis

An effective method for array radiation pattern synthesis that allows formulation of the synthesis of a desired pattern as an optimization problem is presented. The solution proposed involves matrix operations based on the equivalent computation. The advantage of this approach is that it does not involve any numerical optimization routines-only ordinary matrix operations are required. Illustrations are presented to highlight the various aspects of the method. The proposed algorithm can be used to design arrays of uniformly spaced elements with nonisotropic and unequal radiation patterns
