COMMUNICATION SYSTEM OF SUPERLOW-FREQUENCY AND VERY LOW FREQUENCY RANGE WITH DEEP-SUNK AND REMOTE OBJECTS Russian patent published in 2009 - IPC H04B13/02 G01V3/12 

FIELD: information technologies.

SUBSTANCE: system contains "n" number of the generators of the sinusoidal current weighted on the extended horizontally oriented transmitting antennas with earthing devices on the ends. The master oscillator of transmitting system consists of the control system, protection and automatics, thyristor rectifier, the device of protection, the independent inverted rectifier of a voltage, the second device of protection, matching device, supply equipment and two input switches. The generator represents a frequency transformer with a direct current link. The master oscillator works in a frequency band of 0.1-100 Hz, its nominal power on an antenna loading makes 100 kW. The female part includes the towed cable antenna, the antenna amplifier and a radio receiver consisting of the analogue-digital block, providing reception of conferrings on major depth in SLF-VLF wave range.

EFFECT: increase of power and reliability of the system in the conditions of the induced noises.
