[2A28-33-02] Inverse scattering analysis for imaging of cavities using sparsity
Keywords:flaw imaging, sparse modeling, anti-plane elastic wave
In this study, we proposed an inverse analysis method based on sparse modeling for imaging defects inside materials and applied it to the problem of estimating the shape of cavities from 2D anti-plane scattered waves. Although it does not always achieve good estimation accuracy, the possibility of cavity shape estimation by the inverse analysis method based on sparse modeling was demonstrated.
