<p>The antenna array is intended for direction finding and has a receiving control processor for obtaining receiver signal samples from the respective space. The processor adjusts the signal weighting for maximising the signal-noise ratio of the combined output signal of the radiator array. For this purpose control loops are used for automatic weighting of the individual radiator signals. The N radiators are arranged in a specified structure and generate a set of N orthogonal beams of mutual continuity. The nth beam is weighted, in order to form a receiving diagram, related to the azimuth, or elevation angle, the unweighted individual diagram signal, and the number of radiators in the structure. The weighting factors, allocated to the radiators are given by a specified term, in order to provide the maximising of the signal-noise ratio.</p> |
