摘要A novel method for through-wall imaging (TWI) illuminated by the transverse electric (TE)
waves is presented. Most microwave inverse scattering algorithms developed are for transverse
magnetic (TM) wave illumination in which vector problem can be simplified to a scalar one, which
less works have been reported on the more complicated TE case. In the TE case, the presence of
polarization charges makes the inverse problem more nonlinear. This paper uses the self-adaptive
dynamic differential evolution (SADDE) algorithm to recover the shapes of the two dimensional
conducting cylinders by TE plane wave illumination. Based on the boundary condition and the
measured scattered field, a set of nonlinear integral equation is derived and the imaging problem is
reformulated into optimization problem. The SADDE algorithm is employed to find out the global
extreme solution of the object function. Numerical results show that the shapes of the conductor are
well reconstructed. In addition, the effect of Gaussian noise on the reconstruction is investigated.
