| titleOfInvention | Multi-element antenna system and array signal processing method |
| abstract | A multi-element antenna feed method and system which has superior side lobe characteristics over precious electronically scanned beam approaches is provided. A multi-element antenna feed system generally comprises a multi-element antenna, an antenna array processor, a receiver, a signal processor for automatic tracking of targets, and an antenna steering control mechanism. The multi-element antenna may comprise alternate configurations and the antenna array processor is coupled to the multi-element antenna. The antenna array processor particularly comprises a diode switching array for combining at least one output of the elements of the multi-element antenna with at least one other output of the multi-element antenna switchably selected via the diode switching array. The method allows control of the antenna system side lobes in both the scanned offset beam plane and the orthogonal plane by an amplitude weighted combination of the selected element beams. This results in an improved capability to reduce crosstalk between two orthogonal tracking channels, offset beam control versus frequency, and a wide frequency bandwidth. |
