A modified phase-shift migration algorithm applied to through wall imaging

This paper proposes a novel phase-shift migration (PSM) based algorithm in the Through-the-wall (TWI) imaging. Unlike the current methods, our technique uses the Green´s function to compensate the multiple reflections between the wall and the free space. This compensation can be carried out as the preprocessing for the traditional PSM. Simulation results using synthetic-generated data show that the proposed method can well enhance the imaging results in the TWI imaging.
