A New Three-Dimensional Warning and Recognition System for Anti-frogman in Underwater Gates

Abstract

The invention discloses a new anti-frogman three-dimensional early warning recognition system for underwater gates, which includes several image sonar sensors evenly arranged on the left bank and right bank of the underwater gate, and a sonar network early warning computer arranged on the bank. The sonar network early warning computer includes an information sending and receiving module, a data processing module, a fusion understanding module, an integrated display module, a control module and an early warning module. Based on the underwater detection technology of acoustic vision, the system is deployed three-dimensionally near the underwater gate. Through multi-source signal fusion batch processing, it realizes multi-target motion estimation, fine identification and classification, and provides sound and light early warning to the monitoring center. The invention can carry out target identification and tracking on frogmen and underwater vehicles at a long distance, and carry out integrated display and automatic early warning in a centralized monitoring room, which plays an important role in greatly improving underwater security capabilities.

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
