| 摘 要： | 面波和多次波等噪音的产生是海上地震勘探的突出特点,如何高保真地对其进行压制一直是信号处理工作的难题。基于重构信号模型的去噪技术通过不同的方法,充分考虑不同入射角度和横波地震信息,重构信号模型,分离出剩余信号,然后针对剩余信号进行去噪处理,利用建立的信号模型和剩余有效信号结合,得到有效地震信号,达到突出有效信号衰减噪声的目的。 |
| 关 键 词： | 高保真 去噪 信号模型 信噪比 反演 |

| Abstract: | Surface and multiples wave are the prominent noise in marine seismic exploration.How to attenuated these noises has been a significant problem for seismic data processing.Model-based signal reconstruction noise attenuation method uses a different way to reconstruct the signal model which consider the near and far offset and shear wave signal to isolate the residual signal,and attenuate the noise for the remaining signal,then obtains the effective signals by combining the constructed model signal and the res... |
