A simple linear transformation referred to as the equivalence theorem is used to reduce many problems of elliptical arrays, which may operate in a multipath correlated interference environment, to those of their circular equivalents. Then a preprocessing technique in conjunction with the conjugate gradient method (CGM) is used to find the optimal weights of the resultant circular array. The pattern obtained has its maximum in the direction of the desired signals. This method is extended to the case of many desired signals. Such an array is suitable to act as a smart array in multipath telecommunication channels.
