<p><P>PROBLEM TO BE SOLVED: To provide a radar device for flying objects capable of tracking targets with a high degree of accuracy even when a tracking target is missed or a plurality of tracking targets is found. <P>SOLUTION: The radar device for flying objects includes a first signal processing section generating a plurality of beams to search tracking targets, a second signal processing section generating single beam to track the tracking targets, and a third signal processing section estimating directions of a plurality of the tracking targets from received signal. An antenna controller 60 changes alternatively signal processing among the first signal processing section 41, the second signal processing section 42, and the third signal processing section 43, and the third signal processing section 43 estimates the directions of a plurality of tracking targets from received signal by using the MUSIC technique. At the same time, the first signal processing section 41, the second signal processing section 42, and the third signal processing section 43 implement in parallel determining and tracking of tracking target 70. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
