Underwater acoustic communication detection method, device and apparatus and storage medium

Abstract

The invention discloses an underwater acoustic communication detection method, device and apparatus and a storage medium. Compared with the prior art in which underwater detection and underwater communication are independently designed and used as independent equipment, the underwater acoustic communication detection method has the advantages that underwater detection and underwater communicationare combined, a to-be-transmitted signal is generated in a mode of adding a leader sequence and a single-frequency signal, underwater communication with a communication node is carried out through theto-be-transmitted signal, a target echo and a target communication signal are extracted from the received to-be-processed signal, Doppler estimation and delay estimation are carried out on the targetecho for multiple times to obtain a detection result, and communication demodulation is carried out based on parameter information in Doppler estimation and time delay estimation processes to assistin obtaining a target communication result, so that detection of an underwater object in a communication node coverage range is completed while inter-node communication is realized, underwater detection and underwater communication are carried out simultaneously through one piece of equipment, the size of a platform is reduced, the system energy is saved, and the concealment is enhanced.

Description

technical field [0001] The present invention relates to the technical field of underwater acoustic communication, in particular to an underwater acoustic communication detection method, device, equipment and storage medium. Background technique [0002] Underwater target detection is mainly through acoustic means, which can adopt active and passive working modes, use target reflection echo or target radiation noise, and use acoustic element array and time correlation operation to obtain space and time gain, so as to improve underwater target detection The purpose of the action distance. Underwater communication technology uses sound waves as the carrier to realize the transmission of information in the ocean. With the development of science and technology, whether in civilian fields such as underwater exploration and operations or in military fields such as underwater operations, underwater equipment is moving towards informationization, system development in the direction ...
