The invention discloses an underwater acoustic communication detection signal generation method, device and equipment and a storage medium, and the method comprises the steps: obtaining an initial OFDM communication signal and a leader sequence compared with the prior art in which underwater detection and underwater communication are independently designed and used as independent equipment and different signals are respectively used for underwater communication and underwater detection; and generating a single-frequency signal corresponding to the initial OFDM communication signal, adding a leader sequence and the single-frequency signal to the initial OFDM communication signal to generate a communication and detection integrated signal, and detecting an underwater object within the coverage of a communication node while performing underwater communication between communication nodes through the communication and detection integrated signal. Therefore, the effect of underwater acousticcommunication detection integration is achieved.
Description
technical field [0001] The present invention relates to the technical field of underwater acoustic communication, in particular to a method, device, equipment and storage medium for generating an underwater acoustic communication detection signal. 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 devel...
