LIGHT-WAVE INTERFERING DEVICE

PROBLEM TO BE SOLVED: To provide a light-wave interfering device capable of simultaneously dealing with a plurality of flying objects to further improve safety and defending performance. SOLUTION: This light-wave interfering device comprises a plurality of interfering portions 31, 32, and the information on flying objects acquired by a flying object alert portion 10 is given to any of interfering portions through a control portion 20. The control portion 20 recognizes coverage of each of interfering portions 31, 32, and the information on flying object is given to the interfering portion expanding the coverage, when the flying object arrives at any coverage. The interfering portion extracts the azimuth direction of the flying object when the information on flying object is given, and irradiates the azimuth direction with interference light to interfere with a course of the flying object. Further an evaluation function is introduced to evaluate "which flying object is dealt by which interfering portion" while applying the evaluation function as an index. As the flying object can be dealt by the optimum interfering portion at all times, the defending performance can be improved. COPYRIGHT: (C)2006,JPO&NCIPI
