Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater vehicle defense device mounted on a ship.

[0002]

2. Description of the Related Art A conventional underwater vehicle defense decoy is a self-propelled vehicle that deceives a noise-detecting underwater vehicle approaching its own ship to deceive it and guide it away from the ship. It was a thing.

[0003]

A conventional underwater vehicle defense decoy can guide a noise detection type underwater vehicle approaching its own ship to a distance from the own ship, but the underwater vehicle does not When it recognized that it was a decoy by passing through the decoy or changing the detection frequency mode, it would follow its own ship again.

In order to solve the above-mentioned problems, the present invention guides the underwater vehicle to the decoy while noting that the noise detection type underwater vehicle is not recognized as being decoy, in addition to the noise reduction of the own ship. The object is to provide an underwater vehicle defense device that allows a decoy to hit or pass in the vicinity and completely destroys the decoy.

[0005]

The underwater vehicle defense system of the present invention is a decoy controller for outputting a control signal, a noise controller for receiving a control signal from the controller and outputting a decoy and launcher control signal, A decoy launcher that inputs decoy and launcher control signals from the controller and outputs a decoy control signal, a decoy control signal from the decoy launcher, and an acoustic transducer for noise transmission, an underwater vehicle approach detection sensor, and a detonator And an underwater vehicle defense decoy provided with explosives, and a noise control signal output from the noise controller 2 that receives a detection signal from a sensor that detects the launch of an underwater vehicle, To the noise processor, which outputs a noise sound signal to the noise processor and receives the noise generated by the ship, and inputs the noise to the noise controller via the signal processor. It is characterized by comprising a noise receiver transmitter that emits sound waves enter the issue.

[0006]

In the above, when the control signal is sent to the noise controller by the decoy controller, the noise controller outputs the launcher control signal to the decoy launcher, and the decoy launcher launches the underwater vehicle defense decoy, and the underwater navigation. If a projectile explodes, it will fly to a position that is beyond the influence of its own ship and float.

After the above state, the noise receiving transmitter constantly receives the noise generated by the ship, and inputs it to the noise controller through the signal processor, and the noise controller continuously outputs the noise generated by the ship. Monitor.

In this state, when the sensor detects that the underwater vehicle is launched from another ship to the own ship, and the detection signal is sent to the noise controller, the noise controller sends the noise control signal. Input to the signal processor, the signal processor sends a noise acoustic signal to the underwater vehicle defense decoy, and the underwater vehicle detects the noise receiving transmitter in the opposite phase to the noise emitted by the ship. Sends a noise sound signal in the frequency band to be used.

The noise reception transmitter that receives the noise acoustic signal generates a sound wave in a frequency band detected by the underwater vehicle in a phase opposite to the noise emitted by the own ship, and cancels the noise of the own ship. Further, when the underwater vehicle defense decoy receives a noise acoustic signal, the underwater vehicle defense decoy emits noise similar to the noise generated by the own ship, and attracts the underwater vehicle near the decoy.

When the underwater vehicle approaches the underwater vehicle, the underwater vehicle approach detection sensor provided in the underwater vehicle defense decoy operates to explode explosives through the detonator to Destroy the mid-water vehicle.

By the above, the noise generated by the own ship is canceled to make it difficult for the underwater vehicle to detect the own ship.
A device that can guide and destroy an underwater vehicle to the underwater vehicle decoy is realized.
