Abstract

In order to cancel the noise in TDR signal and retain the faint reflectometry signal made by deformation of rock and soil, it is proposed to use method integrated filtering and noise canceling based on wavelet transform with characteristic of TDR signal.One engineering case showed that useful signal implicated can be visualized highlightly by using this method. The method is more clearly and more useful than other method which only using some kinds of detail signals acquired by simple wavelet transform.
- deformation monitoring,
- time domain reflectometry,
- wavelet transform,
- filtering and noise canceling
