N2 - The modeling of through-wall sensing using ultra-wideband (UWB) signals is considered. The combined method of ray tracing and diffraction (CMRTD) is employed to analyze the interaction between the UWB signal and the target. The result is obtained in frequency domain, and then transformed into time domain by use of inverse Fourier transform dFD. Scattering from a two-dimensional (2D) perfectly conducting circular cylinder is calculated and the result is shown in agreement with that obtained from the eigenfunction expansion method. Furthermore, the attenuating effects of walls are considered based on the geometrical optics. Numerical results of scattering from a 2D perfectly conducing circular cylinder behind a homogeneous, single-layered wall are given in both graphical and tabular formats.
