PURPOSE:To increase the feeding source without spoiling the function of the monopulse measuring angle, by dividing the feeding unit for exciting plural arrayed antenna elements, into plural parts, and providing plural feeding means for supplying a microwave to each feeding unit. CONSTITUTION:A signal which has been input from the sending signal input terminal is distributed to two parts by the in-phase 2 distributor 14, is amplified by the amplifying units 9a, 9b, and signals which have been distributed to two by the hybrid circuits 7a, 7b through the circulators 8a, 8b are fed to the upper right array 2-the lower left array 5, and are radiated from the antenna element 6. A receiving signal from the antenna element 6 is added by the feeding unit 1, it is compounded to a sum signal and a difference signal by the hybrid circuits 7a, 7b, and it is output from the sum signal output terminal 11 and the elevation angle difference signal output terminal 12. Also, a difference signal of the upper part and a difference signal of the lower part are added by the hybrid circuit 7c, and they are output from the bearing difference signal output terminal 13. |
