Two-dimensional near-field microwave holography

A new two-dimensional (2D) holographic microwave imaging technique is proposed to reconstruct the 2D image of a target. It is based on the Fourier analysis of the data recorded by two antennas scanning together two separate rectangular parallel apertures on both sides of a target. The complex back-scattered signals of the two antennas are first processed to localize the target in the range direction. Then, the 2D image of the target is …
