ABSTRACT:
A beam of a main antenna is scanned at a constant speed in the direction of compression of the beam width over the range of from (c-a) degree to (c+a) degree with an arbitrary angle c set as a reference angle, and a beam of a sub antenna is scanned by using a phase shifter at a constant speed in the direction of compression of the beam width over the range of from (c-b) degree to (c+b) degree where b represents an angle corresponding to the first zero point of a pattern of the sub antenna and larger than the 1/2 scan angle a of the main antenna. Received signals of both the antennas obtained by the beam scans are subjected to an in-phase multiplication process in a multiplying circuit for beam compression of the received pattern of the main antenna.
