摘要
为了实现海洋环境电场信号中船舶轴频电场信号的有效提取,利用Hilbert-Huang变换,通过对轴频电场信号进行经验模态分解和Hilbert拟数据与实验室船模实测数据处理结果均证明了该方法的有效性。
In order to realize effective extraction of ship shaft rate electric field signal in marine environmental electic field,this paper uses Hilbert-Huang transform to obtain a certain number of intrinsic mode function,achieves the time-frequency analysis of shaft rate electric field signal and noise separation by empirical mode composition method and Hilbert transform.The effectiveness of the method is verified by the processing results of simulated data and laboratory ship model measured data.
