Embodiment Construction

[0018] When our side discovers the enemy fleet on the high seas, let our submarine Q attack an enemy target H, and our submarine Q sneaks to the one that is far away from the enemy target H and is not easy to be found and thinks it is the most advantageous Sonar-guided torpedo D launch and its monitoring point, after roughly calculating the advance of launch, sonar-guided torpedo D can be launched towards the enemy target H, followed by sonar-guided monitoring Device P.

[0019] The sonar system of the sonar guidance monitor P can select the sound wave frequency of about 4000 Hz (the best frequency for long-distance transmission) to work. It can be suspended below the water surface by a floating ball, or it can be sunk to the bottom of the water (the task of monitoring the torpedo hitting the target may have been completed during the time period of its sinking process), and the sonar wave X launched by its sound wave launcher 1 is aimed at the attacked enemy target H, so that ...

Abstract

The invention is a kind of sonar guidance torpedo system and the application method, the sonar guidance system is made up of: torpedo and the orientation sonar receiving device on the torpedo, and the independent sonar guidance monitor made up of sonar transmitting device and the sonar receiving device; the key point of the using method is: it transmits sound wave to the target through sonar guidance monitor, and receives the reflected wave of sound wave by the target and locks the advancing direction of the torpedo, until the torpedo hits the target.

Description

technical field [0001] The invention relates to a guidance technology and a guidance method for underwater torpedoes. Background technique: [0002] At present, the guidance technology based on wireless (mainly electromagnetic wave) technology has been quite maturely applied to missiles traveling in the air, and has achieved the purpose of very precise guidance. However, such very precise guidance missiles are not suitable for underwater Targets, especially underwater swimming targets, are powerless. ——The wavy interface between the two mediums of air and water, which can never be in a stable state, will seriously interfere with the guidance accuracy of missiles, which establishes the status of torpedoes as underwater weapons in naval warfare. [0003] According to existing concepts, the effective range of sonar technology in the water is limited in the military, and the travel speed of torpedoes in water is much slower than that of missiles in the air. If the sonar-guided...
