Microwave Holographic Imaging Using the Antenna Phaseless Radiation Pattern

In this letter, we propose a three-dimensional microwave holographic imaging approach for the cases where the object is in the far zone of the antenna but the measurements are performed in the near zone of the scattering object. Typical applications include concealed weapon detection, through-the-wall imaging, etc. In the proposed approach, the phaseless radiation pattern of the antenna, acquired through measurements, is employed to improve the …
