摘要
船舶电场只能减少,不能消除。文章介绍了船舶电场信号的提取方法,并分别通过小波和时频分析方法对所得信号进行降噪。利用数据融合技术对信号进行综合处理。
The electric field is the intrinsic characteristic of a ship. The measurement for electric field of a ship is great ly disturbed by noise in shallow sea. Wavelet transform and time-frequency analysis are used for noise reduction. And after that, all the signals are processed by the mothod of data fusion.
