| Summary: | The present invention discloses an antenna system comprising a multifocal reflector having at least two reflecting segments having different curvatures defining at least two different spaced apart focal points, such that the multifocal reflector is configured and operable to receive radiation incident on the segments at different incident angles within a certain angular range, and reflect the incident radiation onto the at least two focal points in a focal axis, thereby creating focused radiation formed by at least two differently focused portions of radiation; a phased array feed antenna unit located perpendicularly to the focal axis and comprising a plurality of antenna elements for receiving/transmitting at least two differently focused portions, and a feed network connected to the plurality of the antenna elements for selectively actuating the antenna elements for performing electronic scanning of the space area aimed at detecting target. |
