Partial control for wide-band interference suppression using eigen approach

This paper presents a simple and efficient array pattern synthesis technique for multiple wideband interference suppression using only the edge elements of linear arrays. By minimizing the mean-square value of the pattern in the directions of interference, the eigenvector that corresponds to the minimum eigenvalue is computed to obtain the required current excitation of the edge elements, the number of computations is greatly reduced since partial amplitude control of the edge elements is used.
