摘要
在地震资料处理过程中,在对地震资料进行高保真静校正及动校正处理时,需要对地震数据进行插值处理,如何选用使地震信号保真的插值方法显得十分重要。文中采用sinc函数插值算法对地震数据进行插值,分析了sinc函数在地震数据插值方面的优势,并介绍了sinc函数插值的实现方法。通过对实际模型数据例子的试验分析表明,用sinc插值方法能减少由于插值所引起的信号损伤,保护原始地震信号信息。
In a process of seismic data processing, it needs interpolation processing of seismic data when hi-fi static corrections and NMO processing are carried out, so how to select interpolation method adapted for hi-fi seismic signal is important. The paper uses Sinc function interpolation algorithm for interpolation of seismic data. The paper analyzes the superiority of Sinc function in seismic data interpolation and introduces the implementing method of Sinc function interpolation. It is shown by test and analysis of real model cases that using Sinc interpolation method can reduce the signal damage caused by interpolation and protect original seismic signal information.
