Thierry Scotti: The Non-Unicity Problem in Non Linear Parametric Identification

Thu, 23 July, 2009, 17:15-18:15, Foyer

The subject of this contribution falls into the category of problems concerned with finding the location, shape, orientation and material characteristics of an object embedded in a well-characterized homogeneous, homogenized or heterogeneous unbounded medium by inversion of scattered waveform resulting from the propagation of probe radiation within the medium. Generally the ill posed nature of such problem is bypassed by adding to the cost function a penalty term involving a-priori information of the target. The present paper propose an alternative that does not appeal to any explicit regularization in order to incorporate the minimum amount of a-priori information in the process of parameter identification of a target.
