针对传统水下目标磁定位时因未考虑海平面波动造成磁场信号测量不准确进而引起磁定位误差较大的问题，通过在原有测磁深度上叠加海平面在该处的铅直位移，将叠加后的深度引入仿真模型的系数矩阵中，再利用仿真模型计算测量深度中包含海面波动的测量点处的磁场，以该磁场作为磁定位的数据源。采用三维Longuet-Higgins 模型描述10个组成波形成的波面运动，分析组成波中最大振幅取0.5 m和1 m两种情况。仿真结果表明，其对应的波面铅直位移在某些点处将大于2 m和4 m。船模试验证实，在不考虑舰船在海面波动下产生的纵倾横摇对磁场测量的影响的条件下，当组成波的最大振幅小于0.5 m，波面的最大铅直位移小于2 m时，海平面波动对磁定位结果的影响不大。
In order to solve the problem of inaccurate measurement of magnetic field signal caused by the failure to consider sea level fluctuations in the magnetic positioning of traditional underwater targets, the lead direct displacement of sea level at the original magnetic measurement depth was superimposed, and the superimposed depth was introduced into the coefficient matrix of the simulation model, and then the simulation model was used to calculate the magnetic field at the measurement point containing sea surface fluctuation in the measurement depth, and the magnetic field was used as the data source for magnetic positioning. The three-dimensional Longuet-Higgins model was used to describe the wave surface motion of 10 component waves, and the maximum amplitude of the component waves was 0.5 m and 1 m. The simulation results show that the corresponding straight displacement of the lead on the wave surface will be greater than 2 meters and 4 meters at some points. The ship model test confirms that the sea level fluctuation has little effect on the magnetic positioning results when the maximum amplitude of the component wave is less than 0.5 m and the maximum lead straight displacement of the wave surface is less than 2 m, without considering the influence of the pitch roll of the ship under sea surface fluctuation on the magnetic field measurement.
