英文摘要：

The positioning technology of a time-harmonic horiziontal dipole in coastal is the theoretical basis of ship＇s localization based on the ship＇s shaft-rate electric field signal. An approach based on genetic algorithm is proposed to search the location of the dipole. Only an electric field sensor in seawater is needed to set up measure the modulus of electric field intensity in X/Y/Z directions at the corresponding positions. A model for position calculation combine the propagation formula of a time-harmonic horiziontal dipole in coastal with genetic optimal algorithm in an appropriate coordinate system is set up, then the position of the dipole can be determined accurately. The simulation results show the proposed dipole localization method is accurate and feasible.
