在一个地震记录道上,如果有可明显区分的两组相邻反射波对,就可以形式地将其上覆层视为一个系统的输入,将下伏层视为输出。在频率域中,该系统的传输函数就是两个反射波的频谱比。该系统的传输函数中消除了激发机制、仪器等记录系统以及上覆介质的影响,仅仅保存有与这两层氽质特性有关的信息。 On a seismic track, if there are two distinct pairs of adjacent reflected waves that are clearly distinguishable, the overburden can be formally considered as a system input and the underburden as output. In the frequency domain, the transfer function of the system is the spectral ratio of the two reflected waves. The system’s transfer function eliminates the effects of excitation mechanisms, instrumentation and other recording systems and overlying media, and preserves only information relevant to these two levels of quality characteristics.
