Abstract :
In this paper the phenomenology of the near-field microwave imaging through walls is examined. A hybrid finite difference time domain (FDTD) numerical technique and physical optics (PO) approximation in conjunction with the phase conjugation method is used, for the computation of the transmitted field through different walls and image formation. Numerical results, delineating features of wideband and wide angle wave propagation and imaging through walls are presented
