地震资料上存在的噪音总可分为两种:一种是由炮点本身所产生;另一种则是由于风、交通等外部因素所引起。后者具有随机性。然而,从某种意义上讲,不管来自目标区还是来自其它区域波反射的震源噪音都是起着决定性作用的。 炮点产生噪音的主要原因是由于地区的近地表不均匀性的存在。这种不均匀性导致了波
The noise existing in seismic data can be divided into two types: one is produced by the shot itself; the other is due to external factors such as wind and traffic. The latter is random. However, in a sense, the source noise reflected by the waves from the target area or from other areas plays a decisive role. The main reason for the noise produced by the shot is due to the near-surface inhomogeneities in the area. This inhomogeneity leads to waves
