波浪研究中的多分辨方法

Multiresolution Analysis in Wave Study

简要介绍了应用子波变换方法进行波浪研究的方法。结合Ｍｏｒｌｅｔ连续子波和Ｄａｕｂｅｃｈｉｅｓ离散子波变换，给出了波浪的依时频谱和多尺度分解，通过应用认为子波变换对波浪的非平稳过程。

This paper gives a brief introduction of the approaches in the wave study with wavelet transform techniques. With the theories of the Morlet continuous and Daubechies discrete wavelet transforms, time-frequency spectrum and multi-scaling decomposition are applied into the wave study. Wavelet transform is of great importance to the wave study in nonstationary process, localization and nonlinearity.
