地震反射记录不仅包括原始反射波(一次反射)而且含有各种比例的随机噪声,规则的低速噪声,例如面波、多次反射能量、绕射波、折射反射波和各种其他型式的假反射。而且,由于表层能量传播特性的变化使原始反射品质恶化,也由于通常所说的静态和动态校正使到达时间蒙受误差。当信噪比比较高的时候,能准确地计算静态和动态校正值,平均多次复盖(或迭加)
Seismic reflection records include not only the original reflection (primary reflection) but also various proportions of random noise, regular low-speed noises such as surface waves, multiple reflection energies, diffracted waves, refracted reflections, and various other types of false reflections . Furthermore, the arrival time is subject to errors due to the so-called static and dynamic correction, due to the deterioration of the original reflection quality due to changes in the surface energy propagation characteristics. When the signal to noise ratio is relatively high, can accurately calculate the static and dynamic correction, the average multiple cover (or superposition)
