ABSTRACT:
An off-line processor arrangement for a broadband accelerated convergence adaptive antenna array wherein signals from a plurality of antenna elements are applied to respective identical tapped delay lines (T) the outputs of which are fed through individual signal weighting means to a beamforming network (BFN), the arrangement including one or more lattice filter means (LF) to which the auxiliary antenna element signals are applied together with the output response of the beamforming network to compute sets of weight correction vectors (* W) with which to update weight coefficients and means for storing said updated coefficients, said stored coefficients being applied to the individual signal weighting means to weight the outputs of the tapped delay lines.
