Abstract

Non-Destructive Evaluation is concerned with developing techniques and methods for the quantitative characterization of materials or structures. The focus of this paper is on its application for flaw detection in steel materials. We compare two ultrasound imaging techniques, namely the Synthetic Aperture Focusing Method (SAFT) and Total Focusing Method (TFM) along with Phase-Correlation, a global motion estimation technique, regarding their performance on motion estimation of the probe. Simulation results show that for high level of noise, the TFM with the proposed motion estimation method worked more satisfactorily than SAFT technique did.
