Abstract :
SICS, through the concept of equivalent scattered field, formally integrates sensor coupling and interaction effects. In this paper, both forward and inverse scattering problems were validated with experimental data. It is slow possible to experimentally reconstruct complex permittivity profiles using classical NLRA when the presence of sensors is non-negligible, allowing significant reductions in model noise. EV6 versatility is furthermore established by its extensive modeling capability: both open-space modulated scattering system and water-filled microwave scanner were successfully simulated Directions for future work include modeling other existing experimental systems and developing higher dimension algorithms.
