A qualitative two-step inversion approach for the reconstruction of sub-surface defects

Résumé

In this work, the problem of the localization and shaping of buried objects or voids is addressed considering an innovative two steps strategy in order to enhance the reconstruction accuracy. In particular, at the first step the approach is aimed at firstly estimating the region-of-interest where the defect is supposed to be located. Then at the second step, the qualitative imaging of the object is improved through a level-set based shaping procedure. In order to assess the effectiveness of the proposed approach, selected numerical results concerned with different scenarios and noisy data are presented and discussed.
