In this paper we establish a layered soil model with full wave electromagnetic simulation software package FEKO to characterize subsurface objects, in particular landmines and improvised explosive devices (IED's). We perform a parametric study of the landmine Radar Cross Section (RCS) by varying the material properties (permittivity and conductivity) of the landmine, the depth of the landmine, as...
In this paper we investigate the Radar Cross Section (RCS) of subsurface objects under tapered electromagnetic wave illumination. A layered soil model is incorporated into full-wave simulation. The tapered wave is approximated by superposition of a set of plane waves whose magnitude and polarization are carefully chosen to form an incident beam with finite spatial width. The proposed strategy of modeling...
