Abstract
An antenna system comprises a main antenna for use of transmission and reception and a dedicated sub-antenna for use of reception. The antenna beam of the antenna system is scanned in the direction of a beam width to be compressed. Both received signals of the main antenna and the sub-antenna are fed to a signal processing circuit and a multiplying circuit, and converted to power signals and then multiplied each other. In this processing, only if the cosine value corresponding to the phase difference between the received power signals of the main antenna and the sub-antenna is positive, the multiplication between the received power signals is carried out and the result is further multiplied by the cosine value, and then the obtained signal is output as a final output signal.
