Time-Domain Inversion with the IMSA-FBTS Approach

In this paper, the problem of localization, shaping, and reconstructing the dielectric permittivity of a dielectric target is addressed. The inversion technique processes the time-domain scattered field data to reconstruct with an increasing degree of accuracy the unknown scatterer by exploiting an iterative multiscaling procedure. Preliminary numerical results are presented to validate the time-domain multi-resolution multi-step approach.
