seismic reflection signal

Before analyzing seismic wave anomaly and velocity profiles. the polarity of reflected signal should be adjusted to be same as the physical significance of reflection coefficient.

在震波异常与速度剖面分析之前。应将反射信号之极性调整到与地层中反射系数之物理意义相一致。

In geophysics, reflection refers to the seismic energy or signal that returns from an interface of contrasting acoustic impedance, known as a reflector, according to Snell's law.

在地球物理中，反射指的是地震能量或信号在反射面（具有不同声阻抗的地层分界面）处按照斯奈尔定律发生的回转。

Using TFCC and correlation algorithms for processing of same practical vibroseis seismic data showed that the former could better suppress noises and detect weak reflection signal distinctively.

用TFCC算法和相关算法来处理相同的实际可控震源地震数据，显示前者能更好地压制噪声，并能清晰地检测到微弱回波信号。
