The reflection characteristics of T(0,1) mode guided wave for an aluminum pipe with both circumferential and axial defects are discussed in this paper. Three-dimensional finite element models of cracked pipes are established in the software package ABAQUS/EXPLICIT for investigating the reflection characteristics from defects with different circumferential and axialextent. The T(0,1) mode is incident from one end of the pipe and the defect is located by using the pulse echo method. The corresponding experiments are done with MSGW to verify the simulation results. It has been found that the reflection coefficients have nearly linear relation with the section loss, and that the reflection signals is the joint result of interference between reflected signals from both front and back ends of the defect.

Traditional digital band-pass filter、adaptive filter、wavelet threshold de-noising has a certain effect on filtering the guided wave signal noise. However, it is still hard to detect the small defect. In this research, we proposed a method which combining complex Morlet wavelet time-frequency analysis and matching pursuit algorithm based on Gabor dictionary. Guided wave signal will be transformed by continuous wavelet first, then matching pursuit algorithm will be used to decompose and approach the signal, the signal will be reconstructed via superimposing on each scale signal at last. The experiment of magnetostrictive guided wave detection of defects in pipe demonstrated that the filter algorithm we proposed is effective in defect detection and raising the signal to noise ratio.
