Abstract:The applicability of matched-field processing (MFP) [Baggeroer et al., IEEE J. Ocean. Eng. 18, 401–424 (1993)] techniques to localize sources of vibration in structures and to perform nondestructive testing is explored. MFP is a generalized procedure of array processing used in ocean acoustics to either localize sources or perform inversions. MFP involves correlations between the solutions (or ‘‘replicas’’) of the wave equation for a given acoustic model of the ocean and the data measured at an array of sensor… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
