<p>PURPOSE: To improve a target shooting performance by extending the beam width of a proximity (VT) fuse antenna when a target has a high speed, and quickening the timing of initiation. CONSTITUTION: In the guided flying body M, a relative speed signal is transmitted from an output control part 28 to a relative speed judging part 29 after a target 1 is detected, and when it becomes a prescribed relative speed or more, a high level signal is transmitted from the relative speed judging part 29 to a beam width control signal generating part 30. The beam width control signal generating part 30 outputs a beam width variable signal to a VT fuse antenna beam width control part 31, and the VT fuse antenna beam width control part 31 extends the beam width of a VT fuse antenna. Since the detection point is thus transferred to quickly detect the target 1, the explosion timing of a warhead is quickened to improve the target shooting performance of the guided flying body M.</p> |
