| Tau-p变换的频率域算法及Tau-p域的偏移处理 |

| 摘 要： | 针对时间—空间域倾斜迭加算法的一些缺点,本支根据倾斜迭加运算与富里叶变换的关系,提出在频率一波数域实现τ—p变换。在频率一波数域进行τ—p变换,还可与视速度滤波相结合,以便更有效地消除干扰波,提高处理质量。根据τ—p变换频率一波数域算法原理,提出了在τ—p域直接实现偏移处理,同时指出,为了避免假同相轴的干扰,必须进行插值处理。

| Abstract: | There are some shortpoints of slant stacking when calculated in time-space domain. According to the relationship between tau-p transform and Fourier transform. We provide a new method to calculate slant stacking in F-K domain. In this domain, to combine tau-p process with velocity filtering process gets easier, and high qualities can be alhieved.Based on the basic formulas of tau-p transform in F-K domain, We can do migration process directly in p-w domain to get our final imaging seismic section. Interpolation is used to eliminate the aliasing events in F-K space. Some of the results were examined in practical calculating. |
