音響反射モデルに基づいた地下通信管路継手部の形状パラメータ推定
We propose a joint shape parameter estimation algorithm for an acoustic inspection of an under ground telecommunication conduit. A simple joint shape model with parameters of length and diameter is assumed because the most of the defects in the telecommunication conduit occur at joint. An acoustic reflection dynamics of the joint and appropriate inspection waveform are analyzed from assumed joint model. A joint parameter estimation algorithm is provided based on this joint dynamics. An acoustic
