Operation of a multi-frequency parametric sidescan sonar in an ice waveguide

Hydroacoustic systems for mineral exploration, solving engineering problems and monitoring the ecological state of the world’s oceans are currently being intensively developed. However, the practical use of hydroacoustic systems for solving the problems under consideration, operating in the traditio...
