ELECTRODE SENSOR OF ELECTRIC FIELD STRENGTH IN THE SEA Russian patent published in 2023 - IPC G01V3/02 G01R29/12 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is intended for receiving and measuring electromagnetic fields of extremely and extra low frequencies of natural and artificial origin in the marine environment. Essence: the electrode sensor of the electric field strength in the sea contains the first and second electrodes mounted on a towed dielectric platform at a distance from each other, and the first and second electric motors. Each electrode is made in the form of several flat sections installed with the possibility of rotation on a metal axis perpendicular to the plane of the sections, while the axis of the first and second electrodes is mechanically connected, respectively, to the shaft of the first and second electric motors. The electrode sections are made in the form of a pair or several pairs of identical circular sectors located diametrically opposite in parallel planes. In addition, the electrode sections are arranged so that they form a circle in the plan. The area closer than 0.3 of the radius of the electrode adjacent to the axis of rotation, and the sectoral regions of the electrodes with an angle of 0.1 of the angle of the sector of the electrode adjacent to its leading edge with respect to the direction of rotation of the sections are covered with a dielectric layer.

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