Spherical array space detection positioning device and method based on underwater active electric field

The invention discloses a spherical array space detection positioning device and method based on an underwater active electric field. The spherical array space detection positioning device comprises a spherical array bracket, an electric field emission electrode and electric field receiving electrodes, the electric field emission electrode is arranged at the center of sphere of the spherical array bracket, and the plurality of electric field receiving electrodes are uniformly arranged on the outer surface of the spherical array bracket. According to the spherical array space detection positioning device based on the underwater active electric field, the electric field receiving electrodes are uniformly arranged on the spherical surface, the electric field emission electrode is arranged at the center of the sphere, and the distances from all the receiving electrodes to the emission electrode are completely the same, so that the influence of a main excitation signal on each receiving electrode is inhibited to t
