| Recent advances in underwater acoustics have focused on developing source-identification models that fuse ocean-environment knowledge with guided-learning strategies, an area that holds considerable promise for practical applications. This study proposes a shallow-water acoustic-source identification framework built on a deep-learning model enriched with embedded domain expertise. By integrating a spatial sound field representation with knowledge of physics, a model-optimization scheme and a dedicated recognition algorithm are designed. The resulting architecture, which employs a physics-informed neural network as its core, boosts classification accuracy and improves fault tolerance in source identification. We further analyze how model performance varies under different marine operating conditions and in the presence of uncertainties in acoustic-environment parameters. These investigations enhance the system 爷s capabilities for source tracking and classification, addressing the limited environmental adaptability of conventional models. Finally, the passive acoustic recognition algorithm through shallow-water experiments in realistic ocean settings is validated, thereby demonstrating high-precision, high- resolution source classification. |
