METHOD OF TWO-WAY LONG RADIO COMMUNICATION WITH THE UNDERWATER OBJECT Russian patent published in 2018 - IPC H04B13/02 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to the long-range radio communication and can be used in the establishment of two-way communication and navigation without surfacing of the submerged into the aquatic environment object, for example, submarine, with underwater, surface, ground, air objects and space crafts, including when the water surface is covered with ice. In the method of two-way long-distance radio communication with the underwater object of submarine, surface, ground, air objects and space crafts, including when the water and ground surfaces are covered with ice, for the information radio signals reception and transmission using the radio waves with extremely low power density of 10 mcW/cm² and below at the aqueous environment radio transparency resonance frequencies in EHF and SHF bands. At that, using the EHF and SHF bands tunable and resonant fixed carriers generators and high-sensitivity radio receivers on the fixed SHF or EHF resonant frequency, transmitting and receiving matched contact and remote directional low-noise antennas and antenna systems, data encoding, decoding and processing means located in the radio signals reception and transmission points on the water environment carrier resonance frequencies: EHF: 50.3; 51.8 GHz and the doubling harmonics: 100.6; 103.6; 150.9; 155.4 GHz.

EFFECT: technical result consists in the underwater object with underwater, surface, ground, air and space objects two-way long-distance radio communication method improvement, decrease in the emitted radio waves power, increase in the radio communication information content and secrecy.
