THROUGH-WALL IMAGING: APPLICATION OF SUBSPACE-BASED OPTIMIZATION METHOD

Abstract:
A model for two-dimensional layered medium is proposed for through-wall imaging problem. It is integrated with the subspace-based optimization method for reconstructing the relative permittivity profile in a fast and robust manner. Numerical results have shown that the concealed targets within walls can be reconstructed well using the proposed model even though full aperture of targets is not available due to the presence of walls. The model has also been employed for studying the effect of the presence of walls on imaging.
