摘要
该文针对在地震数据采集器中,使用最小相位滤波器而带来的波形畸变,提出了波形反演的概念,讨论了用逆滤波器直接反演可能出现的问题,并给出了一种反演滤波器的设计方法,经实验模拟证明,该方法是可行的。
This paper raises the concept of waveform reconstruction to solve the problem of waveform distortion caused by a minimal phase filter integrated in a seismic data digitizer. The problems brought by direct waveform reconstruction using inverse filter are also discussed. Then the design method of a kind of reconstructive filter is presented. The method is proved to be effective according to the simulation.
