Multi-source Illumination Approach for Buried Objects Exploration

Many researchers showed the possibilities of a global qualitative reconstruction based on Diffraction Tomography to deliver images for buried objects. However, few investigations have dealt with the improvement of the spatial resolution of the reconstructed image with angular diversity techniques, adopted to enlarge the area of scattering object Fourier-domain data. In this paper, we present a parametric survey showing the influence of the main parameters considered in the imagery algorithm using multi-source illumination technique. Some numerical results are presented to illustrate the contribution of the scattered field from multiple sources in microwave imaging system.
