METHOD FOR SHAPING DIRECTIONAL DIAGRAM OF DIGITAL ARRAY BEAMS

摘要

The utility model relates to radiolocation. A method for shaping a directional diagram of digital array beams consists in receiving of an external signal by all reception channels of array. In each reception channel the received analog signal is transformed to digital code and it is separated square components of received signal. To increase beam shaping rate square components of each reception channel are multiplied to weight ratios that are necessary only for shaping of a directional diagram of odd beams being overlapped with levels of greater than a half power. Then, complex products of each reception channel being related to corresponding odd beams are summed up and so it is got directional diagrams of odd beams. The rest of directional diagrams of even beams is shaped by complex summing up of output signals of odd adjacent beams.
