摘　　要：海洋环境水下电磁场可以分为天然电磁场和人为因素电磁场,因而时域波形中既有随机成分也存在周期成分。论文通过分析浅海近岸多点测试的海洋环境水下电磁场数据,研究了不同条件下环境电磁场的相关特性。分析结果表明,由于海水运动的规律性导致环境电磁场在低频段的相关性很强,可以通过自适应抵消技术抑制海洋环境水下电磁场。Ocean environment electromagnetic field underwater is made up of natural electromagnetic field and human element electro- magnetic field. So random element and period element are both consist in its time domain waveforrrL Correlated property of environment elec- tromagnetic field on different condition is researched via analyzing data of ocean environment electromagnetic field underwater at neritic multi- point test in this paper. Because of sea water velocity motion, it bring almighty relativity at low-frequency stage o[ environment electromag- netic field from analysis. Ocean environment electromagnetic field underwater can be constrained by adaptive bucking technique.
