The controlled evolution of level sets provides a successful framework to solve time-harmonic inverse scattering problems for objects whose contrast with the environment is known but whose shape is unknown. New solution tools extend this framework to the retrieval of objects whose both shape and contrast are unknown

Novel developments of the so-called controlled evolution of level sets [ Ramananjaona et al., 2001b ], which is devoted to shape identification of homogeneous scattering obstacles buried in a known space from time-harmonic wave field data, are considered herein. The emphasis is twofold: regularization of the geometry of the sought...
