Multidimensional Deconvolution for Boundary Reflection Removal and Complete Scattering Characterization in Physical Acoustics Experiments

Abstract

In acoustic wave propagation experiments, waves re ected from the bound- aries of the experimental setup often contaminate recorded data. We propose using multidimensional deconvolution (MDD) to post-process laboratory data such that the boundary-related scattering component is completely removed from recorded data and only the Green's functions associated with a scattering object of interest are obtained. The obtained Green's functions between any pair of points on a closed recording surface completely characterize an unknown scattering object inside the recording surface.
