摘　　要：为将船载地磁测量中舰艇磁场的磁干扰有效补偿,提出了一种舰艇磁性参数的求解方法。通过使舰艇在摇晃状态下绕圈行驶,从而使磁测量值在三维空间上均匀分布,采用遗传粒子群优化(GAPSO)算法可求解出较准确的舰艇磁性参数,同时分析了舰艇姿态测量精度对求解的影响。将求解结果用于船载地磁测量,仿真结果显示船磁干扰被有效补偿,获得了较高精度的地磁场三分量,从而验证了该方法的正确性。A method is proposed to calculate the magnetic parameter of ship for effectively compensating the magnetic interference caused by ship magnetic field in shipboard geomagnetic measurement.Magnetic measuring data distributes symmetrically in three-dimensional space when ship sails rocking in circle.GAPSO algorithm is used to calculate ship magnetic parameters accurately,and the effect of ship attitude measurement accuracy on the calculation result is analyzed.The calculation result is used for shipboard geomagnetic measurement,and the simulation result indicates that magnetic interference is compensated efficiently,and three-component geomagnetic field with high precision can be got,thus the correctness of the method is validated.
