【摘要】 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。更多还原

【Abstract】 A new method for prestack coherent noise elimination is put forward here. Inthe method, whole seismic record is taken as an unit in time-space domain; coherent noise is identified by computer, without windowing of seismic record; filteredpart mainly lies in the area where there exist noises, and other parts are not influenced at all; no false event appears and filtering effect is only in partial area. Processing results of synthetic and real seismic data say that the method is very effective because it suppresses coherent noise as much as possible, without damage of effective signals in all frequency bands.更多还原
