サイルを破壊することができない。2. Description of the Related Art Searching for, detecting, tracking and evaluating a flying object such as a missile (determining whether it is in close proximity or has crashed),
Conventionally, ships and the like have been equipped with a proximity protection device (CIWS) equipped with a radar and a gun or a gun as a device for firing bullets if necessary. Such a proximity protection device can intercept missiles equipped with any type of missile seeker, such as radio waves and light, but consumes enormous amounts of bullets in a short time and cannot withstand long-term use. Also, the missile cannot be destroyed unless it is in close range.

赤外線欺瞞技術(フレア技術)があり、当該欺瞞技術は
遠距離のミサイルに対しても有効であることが知られて
いる。On the other hand, the seeker section of anti-ship missiles is mainly made of radio waves (microwaves), but as a seeker capable of passive and pinpoint attack, a missile having an infrared sensor has appeared. In order to deal with missiles equipped with such infrared sensors, as deception technology to burn gunpowder etc. and bite the missile into it,
There is an infrared fraud technique (flare technique), and it is known that the fraud technique is also effective for long-range missiles.

防御するようにしている。Therefore, conventionally, a missile equipped with an infrared sensor is deceived by using an infrared deception technique when the missile is at a long distance, and a missile flying toward a target without being deceived. I am trying to defend with a close-range defense device at a short distance.

り低減している。However, the conventional infrared deception technology is effective for a reticle type infrared point sensor, but in the case of a missile equipped with an infrared imaging device having a large number of infrared detection elements, the missile tracks the target with an infrared image. Therefore, the effectiveness of conventional infrared deception techniques is significantly reduced.

とは否めない。The infrared sensor uses a mid-infrared region (wavelength: 3 to 5 μm) for a high temperature target such as an aircraft jet engine, and a far infrared region for a room temperature target such as a ship ( Wavelength: 8-12 μm) is used, but in flare technology for burning explosives,
Far-infrared energy emitted from explosives is much smaller than that in the mid-infrared area, and many missiles targeting room temperature targets such as ships are not sufficiently powered by the infrared deception technology that burns conventional explosives. It cannot be denied that there is a feeling.

ができると予想できる結果を得ている。On the other hand, as an infrared deception technique, if the missile is irradiated with an infrared laser such as a CO 2 laser instead of burning explosive, even if the infrared laser has a low output,
The radiance in the direction of travel of the laser is much higher than the same radiance due to the combustion of explosives, so it can be expected to be effective in intercepting missiles. In fact, the inventor conducted an experiment of irradiating the infrared imaging device with the infrared laser at a short distance, and as a result, even a few hundred W-class CO 2 laser at a sufficient distance gives sufficient interference to the infrared imaging device in the far infrared region. You have expected results that you can expect.

しかつ価格も高価になるという問題が生じる。However, since the explosive emits infrared rays in all directions, it is not necessary to direct the infrared rays to the missile, but since the laser propagates in only one direction, the infrared imaging device uses the infrared laser. In order to obstruct the laser beam, a tracking device for continuing to direct the laser along with the movement of the missile is required, resulting in a problem that the device becomes bulky and expensive.

ものである。In view of the above-mentioned circumstances, the present invention uses an infrared laser in combination with a conventional proximity protection device having an automatic tracking function for a target without preparing a special tracking device for the laser, thereby deceiving a missile. The object is to provide a proximity protection device that can be used as a technique.

The infrared laser emitted from the laser oscillator interferes with the infrared imaging device mounted on the flying object and disables its function.

Is a rotary table that can be rotated 360 degrees, and 12 is a turret or turret that is rotatable in a vertical plane by a support member 13 that is erected and fixed on the rotary table. A gun or gun 3 is fixedly mounted on the gun mount or gun mount 12, and a radome 14 having a radar 2 and an infrared laser oscillator 4 are fixed. A drive control system for rotationally driving the rotary table 11 and the turret or turret 12 is provided in the pedestal 10. 5 is a flying object such as a missile equipped with the infrared imaging device 6, 7 is a radio wave emitted from the radar 2, 8 is a bullet emitted from the gun or the gun 3, and 9 is an infrared laser emitted from the infrared laser oscillator 4. is there. When the radar 2 confirms the flying object 5, the radar 2 always faces the flying object 5 and follows the flying object by a tracking mechanism including a turntable 11 and a gun seat or a turret 12. The radio wave radiated from the radar 2 and the emission direction of the infrared laser are substantially parallel.

Radio waves 7 are emitted from the radar 2 to search, detect, track, and evaluate the flying object 5. When the flying object 5 is confirmed and the radar 2 enters the automatic tracking state, the radar 2 always points in the direction of the flying object 5. In other words, the tracking mechanism having the turntable 11 and the turret or turret 12 operates so that the radar 2 points in the direction of the flying object 5. Further, when the radio wave 7 is radiated by the radar 2 that has entered the tracking state, an infrared laser 9 such as a CO 2 laser is emitted from the laser oscillator 4 toward the infrared imaging device 6 mounted on the flying object 5. In this case, the laser oscillator 4 is fixed to the turret or the turret 12 similarly to the radar 2 (sharing the tracking mechanism with the radar) so that the radio wave 7 and the infrared laser 9 are emitted substantially in parallel. Therefore, it is not necessary to provide a tracking mechanism on the laser oscillator 4 itself.

加え得ること、等は勿論である。In the embodiment of the present invention, the case where the low power CO 2 laser oscillator is used as the infrared laser oscillator has been described, but any infrared laser oscillator may be used as long as it can interfere with the infrared imaging device.
Of course, various changes can be made without departing from the scope of the invention.

減が図れるという利点も合わせ持つ。As described above, according to the proximity protection device of the present invention, with respect to a flying object such as a missile equipped with an infrared imaging device which cannot be obstructed by the conventional infrared deception technology for burning explosives, By using the infrared laser, its powerful radiance characteristics can be used to provide sufficient interference, and the running cost is lower than the infrared deception technology that burns explosive, and it can be used repeatedly, and explosive discharge Not only does it have the advantage of eliminating the need for a cylinder installation location, but the search, detection, tracking, and evaluation essential for laser jamming are made possible by sharing it with an existing gun or gun equipped proximity protection device. You don't need any special equipment. It also eliminates the need to shoot down flying objects such as missiles that are obstructed at long distances, and has the advantage of reducing the consumption of bullets.
