METHOD OF TRANSMITTING INFORMATION WAVES FROM SEA MEDIUM INTO ATMOSPHERE AND BACK Russian patent published in 2016 - IPC G10K11/00 

FIELD: hydrophysics.

SUBSTANCE: invention relates to hydrophysics, geophysics and radio physics. It can be used in systems of environment lighting, complex monitoring fields of different physical nature of artificial and natural sources, using long-range technology of transmitting information waves in marine environment, as well as from sea medium into atmosphere and back. Summary: method of transmitting information waves of marine environment in atmosphere and vice versa consists in formation of working zone in medium, which is created due to radiation of signals of close audio frequency and signals of transmitted information introduction to it. Fundamental distinction of declared method from prototype consists in that one radiating and two receiving acoustic transducers are arranged on opposite boundaries of medium and formed between them continuous nonlinear working zone, consisting of two horizontally spaced apart in area of receiving parametric antennae. Using these antennae nonlinear converted scanning wave is received, then their phases difference signals are measured to transfer scale in high-frequency domain, narrow-band spectral analysis is carried out and transmitted via radio communication channel in information-analytical centre (IAC) located in atmosphere. In control signals are generated IAC and transmitted via radio channel back to radiating channel system. Information waves of different physical nature field are used natural and artificial sources of marine environment. Signal frequency illumination medium close audio frequency is set in range of tens-hundreds Hertz. Use of waves radiated by ships and underwater vehicles, in disclosed method, enable increased capacity of transmitted and received information.

EFFECT: technical result is generation and far transmission in marine environment information waves (underwater communication, information fields medium and objects), as well as from sea medium into atmosphere and back to radiating channel system for controlling its operation.
