A low-frequency warning sonar countermeasure device

Abstract

The invention relates to a low-frequency warning sonar countermeasure device, which includes an acoustic subsystem, an autonomous energy subsystem, and an anchoring depth determination subsystem; wherein, the acoustic subsystem includes a duty circuit, a remote control receiver, a control computer, and a high-power linear power amplifier. and an ultra-low frequency high-power transmitting transducer; the autonomous energy subsystem includes a marine power energy collection device, an intelligent power management system and a rechargeable battery pack; the mooring depth-fixing subsystem includes an anchoring mechanism, a depth-fixing mechanism, a control compartment and docking interface. The low-frequency warning sonar countermeasure device has the characteristics of low operating frequency, long working hours, can be deployed in key battle sea areas, and can be used in peacetime and wartime, etc., and finally achieves the purpose of supporting our submarines to break through the blockade of the enemy island chain underwater acoustic defense system , Improve the concealment and combat effectiveness of our submarine operations.

Description

technical field The invention relates to the technical field of underwater acoustic countermeasures, in particular to a low-frequency warning sonar countermeasure device. Background technique In the military field, the detection, tracking and positioning of submarines can be realized through sonar. Due to the long detection distance of low-frequency sonar, it is responsible for the early warning task of long-distance underwater acoustic detection; A series of technologies and equipment have been developed to counter sonar, and underwater acoustic technology, equipment and equipment are used to deceive and interfere with the detection of enemy sonar, and reduce the probability of enemy sonar detecting itself, thereby improving its own survivability. This falls under the category of hydroacoustic countermeasures, and more specifically, sonar countermeasures. With the transformation of strategic missions, domestic submarines are responsible for the mission of going out to the...
