Abstract

The invention is suitable for the field of communication, and provides an underwater acoustic communication device and system, and the device comprises: a multi-source underwater acoustic signal output module which is used for transmitting a multi-source underwater acoustic signal to a water environment; and a first detection assembly which comprises a plurality of laser radar modules, a detectionlight beam of each laser radar module can be focused on one or more space detection points, wherein the first detection assembly detects underwater acoustic signals at the multiple space detection points based on the detection light beams and the Doppler effect generated by acoustic vibration. The multi-source underwater acoustic signal output module improves the transmitting efficiency of underwater acoustic signals. The first detection assembly can detect underwater acoustic signals around the equipment. The underwater acoustic signal receiving range is expanded, the detection aperture / range is multiplied under the condition that the equipment size is not greatly increased, the signal receiving capacity of the underwater acoustic communication device is enhanced, the underwater acousticsignal multi-source resolution, acoustic emission and laser receiving are integrated, receiving and transmitting do not influence each other, and implementation of full duplex underwater acoustic communication is also ensured.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an underwater acoustic communication device and system. Background technique [0002] Acoustic waves are widely used in underwater target acoustic detection, underwater acoustic communication, underwater acoustic positioning and navigation, seabed topography measurement, medical ultrasonic imaging, industrial non-destructive testing and other fields. [0003] Among them, Underwater Acoustic Communication (Underwater Acoustic Communication) is a technology for sending and receiving information underwater, and it is the most important and critical technology in the current maritime military. Its working principle is to first convert text, voice, image and other information into electrical signals through the electrical transmitter, and after the encoder digitizes the information, the transducer converts the electrical signals into underwater acoustic signals. The underwater a...
