<p>PROBLEM TO BE SOLVED: To obtain an infrared detection device that is compact and inexpensive, does not affect the flight characteristics and performance of an aircraft greatly without allowing view to be screened by the aircraft itself, and less deteriorates an infrared window in an infrared detection system with an infrared image supply capacity and target search and warning capacities. SOLUTION: A two-dimensional infrared detection element 1 and an infrared sensor 4 with an infrared window being installed on the outer surface of the body or the like are provided, in multiples, on the surface of the body or the like so that a required angle range that is wider than the view of the infrared sensor 4 can be observed, a required range with an instructed azimuth is converted to a video signal from infrared image signals being outputted from each infrared sensor 4 for outputting, and at the same time a target is extracted for judging the degree of threat.</p> |
