中文摘要：

面波压制是地震数据处理中的一个重要问题．常规的处理方法虽然能在一定程度上压制面波，但是在处理过程中只是单一的利用面波的一种特性，例如频率域滤波中利用面波与有效信号频率之间的差别，因此难以有效地压制面波．利用Ridgelet变换可将原始地震记录拓展到（α，τ，p）三维空间，从而可以同时利用地震记录的视速度、时间和尺度域特性差别，实现有效信号与面波的分离．文中通过理论合成记录及实际地震记录的算例，证实了基于Ridgelet变换的面波压制方法是有效且可行的．

英文摘要：

Ground-roll is a regular interferential wave existing widely in seismic data, and it is a difficult problem in seismic data processing to suppress ground-roll. The traditional methods can do these to some extent, but they only use the ground-roll single characteristic during processing. We gain a transform which is valid in seismic processing, namely, Ridgelet transform. It can transform seismic data in （ x, t ） domain to （ α, τ, p ）. So we can use the difference in velocity, time and scale characteristics of seismic data to process and separate different waves at the same time. Examples of processing the synthetic and real data illustrate its feasibility and effectiveness of the Ridgelet transform method in attenuating ground-roll.
