RECONSTRUCTION OF ONE-DEMENSIONAL MULTIPLE-LAYERED MEDIUM USING A TIME-DOMAIN S1GNAL-FLOWGRAPH TECHNIQUE
-
摘要: 本文首次提出重建多層媒質(zhì)的時域信號流圖法。通過多層媒質(zhì)的等效網(wǎng)絡(luò),引出時域信號流圖的概念,建立其使用法則。借此分析了多層媒質(zhì)的時域反射機理,并給出重建方法。

Abstract: 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. -
