F-K域等道距道内插

Iso-spaced trace interpolation in F-K domain

F－K域道内插是沿用F－X域道内插原理，在F－K域计算道内插算子，并在F－K域实现道内插。该方法具有速度快、精度高、内插出的地震道波形自然、背景好、断点清楚、不怕空间假频等优点。文中给出的实际资料计算结果表明，该方法具有理想的内插效果。

With the use of trace interpolation principle in F-X domain,we obtain trace in-terpolation operator then achieve trace interpolation in F-K domain. The method, not influenced by spacial alias,fast offers the accurate interpolation result which has natural waveforms,satisfactory background and clear fault points. Real data results show that this method brings desirable interpolation effect.
