A Hybrid Lebesgue-Space Inverse-Scattering Technique for Microwave Imaging of Objects Hidden Behind a Wall

A hybrid method for through-the-wall imaging, based on an iterative technique performing a regularization in the framework of variable-exponent Lebesgue spaces, is presented in this paper. The exponent function is computed using a preliminary image obtained through the singular value decomposition method. The effectiveness of the approach has been tested by means of experimental data acquired in a laboratory environment.
