Transient wave imaging of anomalies: A numerical study Souhir Gdoura and Lili Guadarrama Bustos

In this paper, we first numerically test the validity of the asymptotic formulas for computing the scattered acoustic pressure by a small three-dimensional anomaly in the near and far fields. We then propose three methods for detecting the anomaly from far-field measurements. We implement time reversal, back-propagation, Kirchhoff and MUSIC imaging techniques.
