摘要
文章从傅立叶变换不能满足信号处理的要求入手引出小波变换,通过对实际地震资料小波变换去噪前后的效果比较,说明了小波变换是一种分离信号的好方法,能够提高地震资料的分辨率。
Due to the fact that Fourier transform can not meet the requirements of signal De-noising,Wavelet transform is adopted.By the contrast of the actual seismic data before and after Wavelet transform,it shows that Wavelet transform is a good way to separate the signal and can improve the resolution of seismic data.
