Abstract
A steerable antenna array ( ) includes a plurality of antenna elements ( ) which receive broad band signals and narrow band interfering signals which together form antenna signals. The antenna signals are combined with weighting signals by combining functions ( ) to form a combined signal, which is filtered by a filter function ( ) to filter the narrow band signals. The filtered signals are sent to a weight processor ( ) which also receives the antenna signals as an input. The processor ( ) generates the weighting signals so that interference from the narrow band signals is reduced.
