本文提出了一种新的叠前相干干扰滤除方法。此方法是在时间—空间域内把整个地震记录作为一个整体进行处理。相干干扰的识别由计算机自动完成，不需对地震记录作开窗处理。被滤除部分主要集中在干扰波覆盖区域，其它部分则不受影响，不会引入假的同相轴，因此整体滤波产生的效应是局部的。合成数据以及实际数据处理的结果表明，该方法是很有效的，在尽可能抑制相干干扰的同时，有效信号在各个频段的能量都得到了很好的保持。
This paper presents a new pre-stack coherent interference filtering method. This method treats the entire seismogram as a whole in the time-space domain. The identification of coherent interference is done automatically by the computer without the need to open the window for seismic records. The filtered part is mainly concentrated in the area covered by the interference wave. The other parts are unaffected and do not introduce fake events. Therefore, the overall filtering effect is local. The results of synthetic data and actual data processing show that this method is very effective and can suppress the coherent interference as much as possible and the energy of the effective signal in each frequency band is well maintained.
