摘要
讨论了小波变换的基本性质,用快速小波算法实现了信号的尺度分解,研究了信号尺度与频率的对应关系,以此为基础,对地震信号在滤波、压噪等方面进行了有益的尝试,结果表明本方法是有效、可行的.
The properties of wavelet transform are discussed. The fast wavelet transform is used to decompose the signal scale by scale. And the relationship between the scale and the frequency is studied. The calculated results prove that the method is effieient in improving the S/N ratio of seismic profile.
