摘　　要：根据测得的电场值确定源的强度和位置很重要。利用组合电偶极子源对舰船轴频电场进行建模,不仅考虑了电偶极子的水平分量,还考虑了垂直分量,利用不同分量电偶极子产生的水下电场的叠加来模拟舰船实际的水下电场。之后研究了基于模拟退火理论同时反演源极距和位置的方法,通过对不加噪声和加噪声模型的试算,验证了该方法的有效性。It is important to calculate the intensity and location of the sources based on the measured electric field.A com⁃bined electric dipole source is used to model the electric field of a ship.The horizontal and vertical components of the electric dipole are considered,and the superposition of the underwater electric field generated by the electric dipoles of different components is used to simulate the actual underwater electric field of the ship.Simultaneous inversion of the pole pitch and position of the dipole is based on simulated annealing theory.The effectiveness of the method is verified by the trail calculate of the no-noise and noise mod⁃els.
