On the imaging of two-dimensional thin inclusions by a MUSIC-type algorithm from boundary measurements
Résumé
A MUSIC-type imaging technique is proposed for the reconstruction of thin, curve-like penetrable inclusions in a homogeneous space. It is based on an appropriate asymptotic formula of the scattering amplitude, here assuming planar excitations. Operating at a fixed non-zero frequency, it yields the shape of the inclusion from scattered far-fields in addition to estimates of the length of the supporting curve. Numerical experiments exhibit how the proposed technique behaves.
