Guided Waves Mode Discrimination in Pipes NDT Based on the Matching Pursuit Method
Journal of Analytical Sciences Methods and Instrumentation, 2012 Ultrasonic guided wave have the multi-modes and dispersive characteristics, and its modes are easy to be converted at boundary or when running into defects in pipes, which makes the discrimination of different guided waves modes of the reflection signals in pipes NDT very hard. In this work, firstly, the experiments are carried out to test two kinds of
