对有限深海浪磁场进行了理论推导，分析了其变化规律并验证了在舰艇动态磁性检测中进行消噪处理的必要性。根据单椭球加磁偶极子阵列混合模型模拟了舰艇磁化磁场，并针对海浪磁场与舰艇磁场频带相近难以有效滤除的特点，采用小波包变换对磁测量值进行分解。仿真结果表明：该方法便捷高效，可将海浪磁场有效滤除，提高磁场测量精度。

This paper has conducted a theoretical deduction of a limited-depth wave-generated magne-tic field ,made an analysis of its variation characteristics and given the verification of the necessity of noise elimination in a ship′s dynamic magnetic measurement .The ship′s magnetizating field is simula-ted with a hybrid model of single spheroid and magnetic dipole array .The wave-generated magnetic field is similar in frequency band to the ship′s magnetic field ,so it is hard to remove the interference . The wavelet packet transform is used to decompose the measured value .The simulation result indi-cates that this method is so convenient and effective as to remove the wave-generated magnetic field and enhance the measuring precision .
