Linear sampling method for imaging an extended crack using limited-range far-field data

Abstract

We apply linear sampling method for reconstructing an arbitrarily shaped perfectly conducting crack in limited-view problem. This is based on the physical decomposition of the multi-static response matrix (MSR) in transverse magnetic (TM) polarization. Various numerical results are exhibited to show the strengths and weaknesses of the applied method.Index Terms-Linear sampling method, perfectly conducting crack, limited-view inverse scattering problem, numerical simulations.
