Cognitive Sonar Intelligence Countermeasures Technology

The active battle sonar abroad adopts low frequency, high power, large aperture array and adaptive processing technology, which integrates active/passive, multiband and multi-function, and presents the development trend of fully adaptive intelligent cognition. Therefore, the research on how to develop effective countermeasures should be carried out. Firstly, the basic structure of cognitive sonar and its challenges to confrontation are introduced on this paper. Secondly, the artificial intelligence technology is applied to the field of countermeasure, and the architecture of cognitive sonar intelligent countermeasure system is proposed. Finally, the key technologies of cognitive sonar intelligent countermeasure are analyzed, which lays a foundation for the research of cognitive sonar intelligent countermeasure technology.
