Abstract
An array of elements suitable for adaptive processing in an extreme jammed environment comprised of a plurality of smaller sub-arrays of element clusters that have natural orthogonal spatial modes of excitation, wherein the improvement comprises sub-arrays with spatial orthogonality of feed modes, cross-sub-array combination to maximize pre-processing sub-array spacing and diversity of relative configuration, a high-input analog nuller used on the pre-processing sub-array therein, a high-input analog nuller is used to null a dominant jamming signal, possibly exceeding normal communication signal levels, so that the sub-array processed signals could then be fed to an antenna processor with simultaneous beam steering and null steering.
