Abstract:

The performance of sonar equipment is closely linked to marine environment. Research on the influences of the marine environment on sonar equipment and actively promoting the development of environmental adaptive sonar equipment are of great significance for comprehensive utilization of underwater detection and communication means，as well as for enhancement of our capabilities in underwater information technology. This paper focuses on analyzing the influences of typical marine environment and processes on sonar performance， including irregular seabed boundaries，seawater properties，and multiscale ocean dynamical processes. Finally， suggestions on environmental adaptation are put forward.
