| 摘 要： | 假频同相轴的地震道内插可以在f-k域内进行，这时的道内插是对原道集的f-k谱展宽后实施的。本文从讨论具有固定时差的同相轴的谱特征出发，分析了原道集谱与内插道集谱之间的关系；然后根据这些关系，实现了道内插。

| Abstract: | The seismic trace interpolation of the aliased events may be implemented in f-k domain. But that is upon f-k spectral extension for the original gathers. Starting from the discussion on the spectral character of events with fixed moveout, the paper analyzed the relation of spectra between original gather and interpolated gather. Based on the relations, a new method is presented for interpolation in this paper. |
