Abstract
For investigating scattering characteristics of an object located above a rough random surface relating to radar applications, we proposed an unconditionally stable finite-difference time-domain (FDTD)-based solver with novel lattice arrangement approach to simulate the scattering from the object/rough surface composite model. The accuracy and performance of the proposed method are thoroughly assessed for 3-D object above a 2-D random rough surface benchmarked against conventional Yee’s FDTD-based method for various polarization, angles of incidence and truncated rough surface sizes. Simulation results demonstrate that valid scattering characteristics of the object and its underlying rough surface can be obtained by the proposed solver with a smaller problem space and shorter simulation time. By presenting this time-domain, full-wave, unconditionally stable, efficient solver for scattering from objects and rough terrain surfaces, this work aims to facilitate access, analysis and understanding of radar targets and environment’s scattering characteristics for the applications of detection, recognition, remote sensing, etc.
