The inverse problem of reconstructing the starlike boundary Λ of an infinitely conducting, cylindrically shaped obstacle from its far field scattering data is investigated. The equivalent source method (ESM) is applied by defining an auxiliary curve Γ inside the unknown boundary Λ on which electric and magnetic current densities are sought to represent the measured fields. Compared to the case of a sole polarization the exploitation of scattering data of both TE and TM-polarization yields significant improvements on the reconstructed boundary Λ
