<p>Apparatus for steering the beam from an antenna element array (1) includes two feedback loops (4,5) for analysing respectively a first signal representative of the total output of the array, which includes noise and unwanted information and a second signal representative of the wanted information. The two signals are used by a computer (6) to adjust each element step-wise until a desired ratio between the signals is maximised and hence the beam is steered to a desired position.</p> |
