摘　　要：船舶电场只能消减,不能消除。在浅海中测量得到某型货轮电场信号,并利用小波分析的方法对所测信号进行了降噪处理。结果证明,小波变换在处理白噪声方面有其特有的优势。The electric field is the intrinsic characteristic of a ship. The measurement for electric field of a ship is greatly disturbed by noise in shallow sea. Wavelet transform is used for noise reduction, and the result shows that most of the noise was reduced except some periodic industry signal which must be reduced by band--pass filter.
