N2 - We consider electromagnetic imaging of targets hidden behind dielectric walls using sparse regularization. We assume that the targets can be suitably represented by a set of unknown filament currents as in the equivalent-source method. We combine the surface-equivalence theorem and the ray tracing to obtain a linear measurement model. We investigate the efficiency of the proposed method in reconstructing both dielectric and metallic targets.
