摘要：

Using vector operation and mirror image method, the expression of the transfer matrix of the electric dipole in the semi-infinite space to the field point in seawater was derived, the transfer matrix characterizing the linear transformation relationship between the electric field intensity and the electric dipole moment was defined, and the invertibility of the transfer matrix was analyzed. Based on the above, a method for locating the source parameters of the electric dipole in the semi-infinite sea area by inversion of the transfer matrix was proposed, and a simulation example verified the feasibility of the positioning method. Results show that based on the proposed method, the electric field strength of two measuring points in the semi-infinite sea area can be used to accurately locate the single electric dipole source in seawater, and the electric field strength of four measuring points can simultaneously locate the two electric dipole sources in the seawater. This method has a small amount of calculation with high calculation speed, and can also be used to locate unknown interface after modification. © 2020, Editorial Board of Journal of Huazhong University of Science and Technology.
