<p><P>PROBLEM TO BE SOLVED: To avoid mutual interference between two systems in a radar apparatus in which two aerials are arranged at the one and the same aperture to use one system for a remote distance and the other system for a close distance and to suppress an increase in data rate of the overall radar apparatus. <P>SOLUTION: A transmitter A 1, an aerial A 2, a receiver A 3, a transmitter B 4, an aerial B 5, a receiver B 6 and a synchronism controller 7 equivalently operate as conventional devices. A beam controller A 8 halts a search bema over the covering area of a radar system for a close distance and controls the formation of a tracking beam. <P>COPYRIGHT: (C)2004,JPO</p> |
