| Abstract: | Guided by multi-sensor information fusion theory and combined with modern information processing technology, data-driven modeling, and scientific computing technology, in this paper, we study key techniques including determining the super-low-frequency acoustic propagation characteristics of a complex acoustic field and recognizing underwater target depths using data-driven modeling. We also describe the schemes and paths of these technologies. Our results reveal that earlier research on ultralow/low frequency acoustic source targets can overcome the problems in traditional acoustic field modeling, and are helpful in detecting shallow-sea ultralow acoustic source targets and improving the underwater acoustic monitoring method. This work has important theoretical significance for improving the measurement accuracy and precision of Sonar detection equipment, and has practical value for China''s coastal defense in shallow sea areas. |
