Abstract
The possibility of compensation of the noise component of the electrode sensor caused by pulsations of the liquid velocity relative to the electromagnetic field sensor electrodes and the possibility of increasing the sensitivity of the receiving device several times is shown. The scheme of the device for reception and measurement of low-frequency electric field in the sea, in which the specified compensation is realized, is offered.
