<p>PROBLEM TO BE SOLVED: To correct an error in the total antenna gain for necessary transmission and reception which is generated when an array antenna which generates a narrow total beam by the combination of two array antennas arranged closely to each other scans in the azimuth and elevation directions. SOLUTION: To correct the total antenna gain of the two array antennas 1 and 2 to a necessary value on the basis of the data of the antenna gain corresponding to the radiation beam shapes and scanning azimuths of the two array antennas 1 and 2, a beam scanning time antenna gain data recording circuit 10 where the gain data of the antenna elements are recorded is provided. To correct the antenna gain at the time of the beam scanning of one or both of the antennas 1 and 2 on the basis of beam shape and scanning azimuth information of the antennas and the data in the beam scanning time antenna gain data recording circuit 10, a beam scanning time array antenna gain corrected value calculating circuit 11 is provided.</p> |
