| Popis: | Given the significance of home environment sensing, a simulation scheme for single static radar cross section measurement, employing the Finite Difference Time Domain (FDTD) method with the frequency range from 0.4 to 3 GHz is proposed, and the scheme is used to carry out the radar cross section of the human body and common objects indoor. The targets to be measured are 3D molding by Computer Aided Design (CAD) firstly and then using a Gaussian plane wave to illuminate the target in far-field conditions. The simulation results clearly show a substantial variation in scattering with azimuth, material, and frequency. The ultimate goal is to achieve radar cross section estimation and differentiation of objects in order to design an ultra-wide band (UWB) radar systems for indoor environment sensing and through-wall imaging. |
