| Summary: | Non-destructive ultrasound inspection of metallic structures is a perpetual high-interest area
of research because of its well-known benefits in industrial applications, especially from an
economic point of view, where detection and localisation of defects in their most initial stages
can help maintain high production capabilities for any enterprise. This paper is aimed at
providing further validation regarding a new technique for detecting and localising defects
in metals, the Matched Filter-based Dual Symmetric Path Inspection (MF-DSPI). This validation
consists in demonstrating the consistency of the useful ultrasound echoes, within the
framework of the MF-DSPI. A description of the MF-DSPI method and the related work of
the authors with it are presented in this paper, along with an experimental setup
used to obtain the data with which the useful echo consistency was studied. The four
proposed methods are: signal envelope analysis, L2-norm criterion, correlation coefficient
criterion and sliding bounding rectangle analysis. The aim of this paper is to verify the
useful echo consistency (with the help of these four approaches), as the MF-DSPI method
strongly relies on this feature. The results and their implications are discussed in the
latter portion of this study. |
