摘　　要：小波变换进来发展迅速,已经被广泛应用于解决地质问题,它能够较准确的描述信号在时间和频率方面的分布特点,同时还可以分析信号在频域和时域中的特征,并且能够采用多种分辨率来对信号进行分析,实现了信号的有损和无损传输。本文简要介绍了小波变换用于地震勘探的发展历史,介绍了小波变换的基本思想、主要概念并对它在地震信号处理中的应用做了总结归纳。Wavelet transform has developed rapidly in recent years and has been widely used to resolve geological problems.It can be used to describe the distribution of the signal in time and frequency accurately,and analyze the characteristics of signals inthe frequency and time domain. Multiple resolutions are applied to analyze the signal to realize the lossy and lossless transmission ofsignal. This article describes the history of wavelet transform for seismic exploration as well as the basic idea and concept of wavelettransform,its application in seismic signal processing is summarized as well.
