ELECTRODE SENSOR OF ELECTRICAL FIELD INTENSITY IN MARINE ENVIRONMENTS Russian patent published in 2021 - IPC G01V3/08 G01R29/12 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is intended for receiving and measuring electromagnetic fields of ultra-low and extremely low frequencies (ULF and ELF) of natural and artificial origin in the marine environment. Details: the sea electric field sensor contains two electrodes installed on a towed dielectric platform at a distance from each other, the first and second electric motors. Each electrode is made in the form of one or several sections located in one plane in the form of a centrally symmetric flat figure mounted on a metal axis passing through its geometric centre perpendicular to the plane of the sections to allow rotation. The axis of the first and second electrodes is mechanically connected to the shaft of the first and second electric motors, respectively. The electrode can be made in the form of two identical square sections, located diametrically opposite to the axis of rotation and connected by a crossbar. The electrode can also be designed as a ring or disk.

EFFECT: increased sensitivity by reducing the noise of the sensor movement.
