In the report the results of theoretical and experimental researches of the nonlinear phenomena in acoustics are discussed. It is shown, that using of these phenomena allows to create sonar devices and integrated systems for underwater and buried objects search, underwater surveillance, mineral and biological resources exploration, ocean environment monitoring. Characteristics of parametrical devices are discussed and results of their applications for solving various problems of hydroacoustics are considered. Ways of sonar means perfection and principles of their construction using methods of nonlinear acoustics are discussed.
