Abstract :
We propose a MUSIC-type algorithm for the non-iterative imaging of one or more perfectly conducting cracks in a homogeneous space R2. It is based on a factorization of the measured Multi-Static Response (MSR) matrix. Operating at a fixed nonzero frequency, it yields the shape of the cracks from scattered far-fields. Various numerical experiments exhibit how the proposed technique behaves.
