Abstract
A steered adaptive antenna arrangement including an adaptive beamforming network 10 to which the output signals of an array of antenna elements are applied, the network having a feedback wherein the summed output of the network is correlated with each element signal, applied to a limiter and added to the steering component whereby the derived value is used to drive the associated weight coefficient, characterized in that the summed output of the beamformer network 10 is further applied to a desired signal estimator 11 the output of which is subtracted from the summed output to provide the feedback input 12 to be correlated with each element signal.
