Using Random Fields to Study Acoustic Structures
Abstract
We propose to use random noise fields to study the structural acoustic and subsequent scattering properties of complex objects. The motivation of this research is results from earlier work that came from our last ONR core programs supported by Code 31 and Code 32. The preliminary research also involved NRL~s Dr. Earl Williams who spent a sabbatical at SIO to get involved with our noise correlation processing and has now subsequently obtained an NRL 6.1 program applying this work to determining the acoustic scattering properties of UXO~s (Unexploded Ordinance) that are buried in sediments. The program proposed here will also allow us to continue this collaboration. This difficult theoretical problem is complicated by external loading of the embedded object thereby requiring the combination of data and theoretical derived matrices with different degree of freedom to be stably inverted to predict scattered fields. This research will involve the mathematical physics of scattering, state-of-the-art numerical methods and data analysis.
