摘　　要：To model the underwater electric potential(UEP) of ships,a multiple point-electrodes method is commonly used.However,it is difficult to determine the total number of point-electrodes,their respective positions and current values.In this paper,the particle swarm optimization(PSO) method is applied to solve the number,positions and current values of these point-electrodes according to the UEP distribution at a known depth below the keel of a ship.A scaled ship model experiment is carried out to determine the effectiveness of the method.The results show that for hulls in a latural corrosion or cathodic protection state,the UEP inversion accuracy can reach 85% at different depths below the keel.This method is suitable for software implementation and can help the simulation and prediction of UEP signatures.
