Deep-sea sound source localization method, computer device, and storage medium

Abstract

A deep-sea sound source localization method, a computer device and a storage medium. The method includes: deploying at least two underwater gliders in a designated sea area, so as to respectively record a broadband signal which is emitted by a broadband sound source (1); obtaining a waveform envelope of the signal, and then calculating a waveform envelope of a simulated signal (2); performing cross-correlation analysis on the two waveform envelopes (3); and determining an estimated value of a distance from the sound source, and finally obtaining an estimated position of the sound source by means of a geometrical relationship (3). By means of the method, deployment of a large-depth vertical receiving array is not required. The system has low complexity, and is easy to deploy and operate, which can be applied to a relatively large area. In addition, simple data analysis and calculation are performed without the need for manual parameter adjustment, and target localization can be achieved only by knowing an approximate azimuth of movement of a target. Underwater gliders have good maneuverability and can be deployed according to task requirements, thereby achieving target localization and tracking in a relatively large area.
