N2 - This study investigates the modeling of through-wall sensing using ultra-wideband (UWB) signals. The combined method of ray tracing and diffraction (CMRTD) is employed to model and study 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. Numerical results of scattering from a two-dimensional (2D) perfectly conducting circular cylinder are obtained and compared with those from the eigenfunction expansion method. Good agreements between the results are achieved. In addition, the attenuating effects of walls are considered and numerical result of scattering from a 2D perfectly conducting circular cylinder behind a homogeneous, single-layered dry wall is presented. The model can be easily extended to handle the dielectric target and the multiple-layered walls.
