Novel underwater gate anti-frogman three-dimensional early warning identification system

Abstract

The invention discloses a novel underwater gate anti-frogman three-dimensional early warning identification system, including a plurality of image sonar sensors uniformly arranged on a left bank and a right bank of an underwater gate, and also includes a sonar networking early warning computer arranged on the bank, the sonar networking early warning computer includes an information transceiving module, a data processing module, a fusion comprehension module, an integrated display module, a control module and an early warning module. The system is based on an underwater detection technology of acoustic and visual senses, three-dimensional deployment is carried out in the vicinity of the underwater gate, and through batch processing of multisource signal fusion, motion estimation and fine identification and classification of multiple targets are realized, and an acousto-optic early warning is provided to a monitoring center. The novel underwater gate anti-frogman three-dimensional early warning identification system can perform target identification and tracking on a frogman and an underwater vehicle at a remote distance, and can perform integrated display and automatic early warning in a centralized monitoring room, thereby playing an important role in substantially improving an underwater security capability.

Description

technical field [0001] The invention relates to a novel anti-frogman three-dimensional early warning and recognition system for underwater gates, belonging to the technical field of underwater gate security. Background technique [0002] Underwater is a unique space compared to land. Electromagnetic waves operate in a very short distance underwater, and when the water is turbid, it is even darker. Therefore, underwater is often a black hole space for human beings. And this also provides fighter planes for special operations or asymmetric warfare. Important channel parts such as underwater gates are at risk of being penetrated by divers or underwater vehicles, which is likely to cause heavy losses. Therefore, a three-dimensional frogman early warning and identification system is arranged near the underwater gate, which can detect early, give early warning and deal with it in time when frogmen invade.

Problems solved by technology

[0003] Conventional image sonar mostly uses a mechanically rotating single beam for area imaging. This working principle is suitable for use in fixed platform or static target imaging, but it is powerless in the face of any moving working platform or moving target, because any movement is for the single beam. cause errors when the beam is finally imaged
