Abstract :
A hybrid approach is proposed to reconstruct a three dimensional penetrable object using near-field data. Electric dipoles as the sources of incident field and measuring the scattered field in near-field region are considered. The aperture which dipoles are located on is shaped like a finite cylinder. The numerical result clearly shows that this inversion algorithm provides a robust procedure which resists against the effect of random noise.
