Abstract

The invention relates to a wireless sonar system based on underwater acoustic communication. The system includes an underwater submersible buoy, a water-surface floating-body module and a display andcontrol module (9). The underwater submersible buoy is arranged at the bottom of water. The water-surface floating-body module is arranged on a surface of the water. The display and control module (9)is arranged on a ground shore station. The display and control module (9) sends an instruction to the underwater submersible buoy through the water-surface floating-body module, working status of underwater sonar (3) installed at the underwater submersible buoy is arbitrarily changed, underwater-sonar data are periodically sent to the display and control module (9), and display is carried out.

Description

technical field [0001] The invention belongs to the technical field of underwater acoustic communication and underwater sonar, and in particular relates to a wireless sonar system based on underwater acoustic communication and a method thereof. Background technique [0002] At present, sonar is an acoustic electronic device that uses the propagation characteristics of sound waves underwater to complete tasks such as underwater positioning, detection, and communication; for example, reconnaissance sonar, image sonar, anti-frogman sonar, etc. Due to the severe attenuation of conventional electromagnetic waves and optical communications underwater, it is impossible to achieve long-distance underwater information transmission. Therefore, underwater sonar data cannot use traditional communication methods, such as radio, optical communication, etc., to realize real-time communication and transmission of underwater sonar data or working status. [0003] At present, the working mod...
