Résumé

The aim of this work is the detection of small inclusions (or defects) in the three-dimensional free space, using near field acoustic data in a quasi-backscattering configuration. The latter is such that for any source point in the antenna path we have an orthogonal line of receivers. Our inversion algorithm is based on a Music type method adapted to the asymptotic form of the scattered field for small inclusions and the data configuration. The efficiency of the procedure is tested against synthetic data.
