摘要
Based on the high amplitude, low frequency and low speed characteristics of ground-roll, and according to the distribution characteristic of ground-roll and reflection wave in wavelet domain and ridgelet domain, a ground-roll attenuation method joint one-dimensional continuous wavelet transform and ridgelet transform is proposed. The results show that the method is effective in attenuating ground-roll,and can preserve low frequency component of the reflection wave, which provides better foundation for continuous data processing and analysis.
