Title:
UNDERWATER ACOUSTIC COMMUNICATION AND DETECTION METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/110408
Kind Code:
A1
Abstract:
Disclosed are an underwater acoustic communication and detection method, apparatus and device, and a storage medium. In the present application, underwater detection and underwater communication are combined with one another. The method comprises: generating a signal to be transmitted by means of adding a preamble sequence and a single-frequency signal; performing underwater communication with a communication node by means of the signal to be transmitted; extracting a target echo and a target communication signal from the received signal to be processed; repeatedly performing Doppler estimation and delay estimation on the target echo so as to obtain a detection result; and performing communication demodulation on the basis of parameter information during a Doppler estimation and delay estimation process so as to assist with obtaining a target communication result.
