High degree of freedom array |
摘要 |
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. |

1. A super-array of elements suitable for a multilevel adaptive processing architecture for the nulling of multiple interferers of differing levels, wherein the interferers span a high dynamic range and have received signal strengths exceeding normal communication levels of the receiver comprising
providing a super array comprised of a plurality of sub-arrays, wherein the plurality of sub-arrays are spaced electrically close (≦Lamda spacing) to facilitate coherent processing in the super-array. |
