摘要
相空间属性提取方法是一种基于小波变换的属性提取方法。由于该方法建立起了小波变换和Hilbert变换之间的联系,因此它既具有Hilbert变换的特性,又具有小波变换多尺度的特性。与基于Hilbert变换的常规瞬时属性提取方法相比,相空间属性提取方法具有抗噪能力强、变分辨率和精度高等优点。将此方法应用于海上实际资料的处理,并通过与常规软件的对比,表明该方法是实用、高效、可信的。
The method for detection of phase space attributes is method of attributes detection based on wavelet transform.Since the method built up link between the wavelet transform and Hilbert transform,it has character of both Hilbert transform and multi-scale of wavelet transform.Comparing with conventional method for detection of instantaneous attributes,the method for detection of phase space attributes has advantage of strong anti-noise ability,variable resolution and high precision,showing that the method is ...
