DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a missile jammer, and more particularly, to a missile jammer that interrupts a sensor such as an infrared tracking missile.

[0002]

2. Description of the Related Art FIG. 9 is a block diagram showing a configuration of a missile jammer (51) disclosed in Japanese Patent Application Laid-Open No. 61-190298. In the missile jamming device (51), the infrared radiator (52) and the modulator (53) are housed in their own defense target (54). Modulator (53)
Modulates the radiation intensity of the infrared light output from the infrared radiator (52).

The missile targeted by the missile jamming device (51) is a missile that tracks a target by an infrared tracking device using a non-image type infrared sensor. In the non-image type infrared sensor, the image of the infrared radiation emitted by the target of the missile is formed on a rotating reticle (a plate with a patterned transmission window), and the infrared light transmitted through the reticle is detected by infrared light. It is photoelectrically converted by the device and output.
The output of the infrared detector is modulated differently depending on the position of the image on the reticle, that is, the direction of the target. With this modulation pattern, the infrared tracking device recognizes and tracks the azimuth of the target.

[0004] The missile jammer (51) sends the infrared radiation emitted from the infrared radiator (52) to the infrared tracking device of the missile in a deceptive manner by the modulator (53) so as to be falsely transmitted to the infrared tracking device. It is intended to give target azimuth information and to avoid being hit by its own defense target.

[0005]

The above-mentioned conventional missile jammer (51) has no effect on an infrared tracking type missile using a two-dimensional infrared image sensor, but also has an effect on the basis of emitted infrared rays. This tells the missile where to defend itself, increasing the risk of shots. Accordingly, an object of the present invention is to provide a missile capable of combating a missile of a two-dimensional infrared image sensor tracking system, a missile of a non-image type infrared sensor tracking system, a missile of a laser tracking system, a missile of a laser guiding system, and the like. It is to provide a jamming device.

[0006]

A missile jamming device according to the present invention comprises: a missile position detecting means for detecting a position of an infrared tracking missile or the like of a partner, a laser beam light source means for irradiating a laser beam, and the infrared tracking missile or the like. And a laser beam directing means for directing the laser beam.

[0007]

In the missile jammer of the present invention, the position of an infrared tracking missile or the like of an opponent flying to his own defense target is detected, and a laser beam is emitted from an unmanned boat or the like separated from his own defense target. Irradiates sensors such as infrared tracking missiles. As a result, a sensor such as an infrared tracking missile is destroyed or obstructed, and the tracking device for the missile is disabled. When the laser beam becomes the target light of the sensor, it guides an infrared tracking missile or the like to an unmanned small boat or the like separated from its own defense target. Therefore, in any case, it is possible to prevent the own defense target from being hit by an infrared tracking missile or the like.
