COMMUNICATION SYSTEM OF ULTRA-LOW FREQUENCY AND ULTRA-RARE-FREQUENCY BANDS WITH DEEP-LOADED AND REMOTE OBJECTS -7 Russian patent published in 2019 - IPC G01S15/88 

FIELD: antenna equipment.

SUBSTANCE: invention objective is to control beam pattern or address data transmission to underwater objects based on construction of spatially distributed several narrow beam patterns which make a wide beam pattern of the transmitting antenna; controlling the beam pattern of a transmitting antenna or transmitting data to underwater objects with selection of oceanic zones and continuous change of said zones to prevent counteraction to deliberate interference. Set goal is achieved by using five current branches in coastal transmitting antenna with possibility of simultaneous operation at five frequencies in "Communication system of ultra-low frequency and ultra-low frequency range with deep-loaded and remote objects", wherein use, both jointly and heterogeneously, of five current branches, or operating frame antennas, for "n" low-power ELF-VLF generators in their spatial distribution, "n" grounding switches, "n" amplifiers, "n" control system units for one long several tens of kilometers of transmitting antenna with current in it, allowing to provide a given magnetic moment to provide communication with deep and remote objects and not to affect electromagnetic compatibility with radioelectronic equipment, transmission line and protection by cable lines of control and communication system of transmitting system of VLF-ELF antenna, as well as creation of environmental safety conditions for a person and the environment, and creation of spatial separation of information transmission channels due to both narrow beam patterns of the VLF-ELV of the transmitting antenna, and illumination of large ocean spaces when underwater objects are exposed to them.

EFFECT: disclosed is a communication system of ultra-low frequency and ultra-rare-frequency bands with deep-loaded and remote objects -7.
