摘要
本文首次提出重建多层媒质的时域信号流图法。通过多层媒质的等效网络,引出时域信号流图的概念,建立其使用法则。借此分析了多层媒质的时域反射机理,并给出重建方法。
A new method to reconstruct multiple-layered medium is first proposedby using a time-domain signal-flow graph (TDSFG) technique. With the equivalent network of the medium, a concept of TDSFG is given, and its rules are derived. Furthermore, the reflection principles in time domain are analysed, and a reconstruction method is establshed.
