Advances in integrated technology of underwater acoustic communication, navigation, and positioning of submarines

The integrated technology of communication, navigation, and positioning is studied on the basis of underwater acoustic to improve the disadvantages in information interaction, bandwidth utilization, and resource limitation when the communication and positioning of the submarine are applied as independent loads. This paper analyzes the development trend of sonar integration by combining the research results of underwater acoustic integration and the application background of sonar based on the development of radar integration. The study is focused on two key points of submarine clusters, namely system structure and signal system. Finally, the application prospect of submarines in two aspects, including the multi-user cluster formation, the underwater measurement and control, and underwater tracking range construction, is conducted. Such exploration and analysis can provide new methods and ideas for the integrated development of sonar technology in the future. © 2023 Editorial Board of Journal of Harbin Engineering.
