Development of Underwater Acoustic Target Feature Analysis and Recognition Technology

Underwater acoustic target recognition is an important supporting technology for the underwater information acquisition and countermeasure, and its core is the target feature extraction. Aiming at the underwater acoustic target radiated noise and the target echo signal, this paper discusses and summarizes the main sound sources and the target feature expression from the underwater acoustic target signals, the feature analysis and extraction methods of the underwater acoustic signal, and the commonly used underwater acoustic target classification methods as well as the recognition methods. The issues in the underwater acoustic target feature extraction and recognition technologies are analyzed, and the development directions in the future are proposed as well.
