Abstract Details

2008, Master of Science, Ohio State University, Electrical Engineering.
Radar imaging techniques for building exteriors have been extensively studied over the past several years. However, through-wall imaging presents us with several challenges. Among them are (1) wall penetrating signal attenuation and distortion and (2) demand of adequate modeling techniques. This thesis begins by reviewing near zone imaging algorithms based on scattering centers, and proceeds with the adaptation of new heuristic edge and corner diffraction coefficients for dielectric wedges using transmission and reflection characteristics of multilayered slab to ensure shadow boundary continuity. The high frequency building characterizing technique is then validated against experimental radar measurement. By using the Ohio State University NEC-BSC code upgraded with the new diffraction coefficients, it is demonstrated that polarization and bistatic SAR can be used in detecting or avoiding certain building features and hidden objects. To improve interior wall and object imaging, the CLEAN algorithm is employed to remove exterior wall contributions using pre-computed scattering signatures.
