Abstract :
A new three-dimensional holographic microwave imaging technique is proposed to reconstruct targets in the near-field range. It is based on the Fourier analysis of the wideband transmission and reflection signals recorded by two antennas scanning together along two rectangular parallel apertures on both sides of the inspected region. The complex scattering parameters of the two antennas are collected at several frequencies and then processed to obtain a representation of the three-dimensional target in terms of two-dimensional slice images at all desired range locations. No assumptions are made about the incident field and Green´s function, which are derived either by simulation or by measurement.
