【摘要】 小波分析具有多分辨分析的特点,在时频两域都具有表征信号局部特征的能力,是一种窗口大小固定不变,但其形状可以改变的时频局部化分析方法。本文从介绍小波分析的发展简史开始,简述小波分析的基本原理,分析和总结小波分析在地球物理勘探、信号和图像处理中的最新应用成果。讨论小波分析目前应用中存在的主要问题,并展望小波分析一些有前景的应用领域。更多还原

【Abstract】 Wavelets analysis has the characteristics of multi-resolution analysis and ability of expressing local features of signal in both time and frequency domains, it is a local analysis method, the window size of which is fixed and unchanged, the window shape of which can be changed, in both time and frequency domains. In this article, starting from the introduction of brief developing histoiy of wavelets analysis, the basic principle of wavelets analysis is briefly described, analyzing and summarizing the new application fruits of wavelets analysis are emphasized in geophysical exploration and signal and image processing. Further more, the main existing problems of wavelets analysis in applications are descussed,finally, outlook of prospect application fields are given to wavelets analysis.更多还原
