f—k域与f—x域联合实现道内插

传统的道内插技术是采用扫描同相轴的倾角，然后沿着干倾角方向加权求和来实现。据采样定理实现的ｆ－ｋ道内插技术及ｆ－ｘ域道内插技术各有利弊。本文在此基础上，联合利用ｆ－ｋ域与ｆ－ｘ域实现道内插，可以达到兴利除弊的目的。

Joint trace interpolation in f-k and f-x domains

The usual trace interpolation is achieved by using dip angles of scanned events and making weighted summation along the dip angle directions. The f-k and f-x do-main trace interpolation techniques based on sampling theorem have their advan-tages and disadvantages respectively. Joint trace interpolation in f-k and f-x do-mains can retain their advantages but remove their disadvantages. Theoretical and real data processing results show that the method can be used to fast produce accu-rate and satisfactory results'
