  • A computation approach of scattering by buried objects is presented by using Finite-Difference Time-Domain (FDTD) method, the Uniaxial Perfectly Matched Layer (UPML), and reciprocity principle. The numerical performance of this approach is in detail investigated by numerical experiments. The Radar Cross Section (RCS) of various buried objects with different electrical size, shape, dielectric constant, are computed and analyzed, from which useful conclusions are obtained.
