基于小波变换的地震信号分时分频相关去噪

Seismic data de-noising based on wavelet transform

摘要: 介绍了Donoho的小波域阈值去噪处理方法,提出了对小波变换尺度上小波系数进行分时分频相关处理去噪后,再重构小波系数的方法,以去除大部分随机噪声。然后,再对重构后地震剖面进行小波域阈值去噪处理。结果表明,使用上述新方法可以有效改善地震剖面处理效果,提高信噪比。

Abstract: In this paper a method with wavelet transform based on Donoho's threshold filter is described.Then Based on this methods,a new method of removing random noises was suggested.The results show that the method can improve signal-to-noise ratio.
