shearlet域和tt域联合压制面波方法
Keywords: shearlet变换,time-time变换,面波压制,自适应,时—空变滤波器
Abstract:
？面波压制是陆上地震数据处理中的重要课题之一，现有的面波压制方法仅考虑信号与噪声在某一方面的差异进行分离，不可避免的会损害部分有效信号的能量。针对这一问题，本文提出了一种基于shearlet变换和tt（time-time）变换联合压制面波的方法。首先利用shearlet变换的高尺度基函数优异的局域性和方向表征能力分离反射信号与低频、高波数的面波；然后，利用tt变换对低频良好的分辨能力，在tt域进行滤波处理，压制大部分的低频、低波数的面波成分；最后，利用shearlet变换提取的较准确的有效信号设计tt域自适应时—空变滤波器，进一步压制残留的低频、低波数的面波成分，再反变换到时间域就得到了压制面波后的最终结果。模型和实际资料处理结果表明：与f-k滤波和单一的tt域滤波相比，本文所述方法在消除面波的同时，能够保持反射波的振幅和相位信息，是一种相对保幅的面波压制方法。
