RADIO-HYDROACOUSTIC SYSTEM FOR TRANSMITTING INFORMATION WAVES FROM SEA MEDIUM INTO ATMOSPHERE AND BACK Russian patent published in 2016 - IPC G10K11/00 

FIELD: physics.

SUBSTANCE: invention relates to hydrophysics, geophysics and radio physics. Radio-hydroacoustic system for transmitting information waves from sea medium into atmosphere and back includes arranged in medium radiating and receiving acoustic transducers connected to radiating and receiving paths, respectively, formed between working zone of nonlinear interaction of waves. Fundamental difference consists in that proposed radio-hydroacoustic system further includes arranged in atmosphere an information-analytical centre (IAC). IAC comprises a unit of systemic analysis, input and output of which through receiving and transmitting radio units are connected to output and input of receiving and emitting channels of system, respectively. Working area is formed using two receiving transducers in form of horizontally spaced apart at receiving points and aligned at point of radiation pervious parametric antennae. Sea ship or submarine is arranged on line of radiation-reception pervious signals for reception or transmission of required information using their standard (laboratory) or overboard hydroacoustic stations. Data signals from output of radio unit of IAC are further transmitted over a radio communication channels to other participants using control system of marine environment.

EFFECT: technical result consists in development of radio-hydroacoustic forming system, as well as measurement and transfer in marine environment information waves of different physical nature of artificial and natural sources in a wide frequency range, as well as underwater communication signals and their transmission from a marine environment in atmosphere and back to radiating channel system.
