METHOD OF COMMUNICATION OF UNDERWATER VEHICLE WITH AIRCRAFT Russian patent published in 2020 - IPC B06B3/00 G10K11/00 H04B11/00 

FIELD: underwater sound and audio communication.

SUBSTANCE: invention relates to underwater sound and audio communication and can be used in hydroacoustic systems for organization of one-way communication immersed in water environment of object with air object. Method of communication of underwater vehicle with aircraft is characterized by that radiating path is located on underwater vehicle and consists of control computer, a pulse generator, a power amplifier, a radiating hydroacoustic antenna, and the receiving path is located on the aircraft and consists of a receiving acoustic antenna, a preamplifier, a band-pass filter, an exciter, a power amplifier emitting radio antennae, wherein the depth of submersion of the underwater vehicle (or its hydroacoustic antenna) shall not exceed the wavelength of the acoustic signal emitted by the hydroacoustic antenna; frequency of acoustic signal should lie in low-frequency (less than 1 kHz) or infrasound range; hydroacoustic antenna must have either a spherical or cylindrical emitting surface; dimensions of underwater vehicle shall not exceed the wavelength of emitted acoustic signal.

EFFECT: broader functional capabilities of communication systems installed on underwater and aircraft, high technical reliability and security of transmitting and receiving information for unilateral communication of underwater vehicles with aircraft.
