A three-dimensional electromagnetic scattering model based on the multiresolution time-domain (MRTD) scheme is presented, in which we apply an anisotropic perfectly matched layer (APML) absorber for open boundary truncation to the MRTD scattering analysis. In this research, we develop an MRTD near-to-far-zone field transform to derive the scattered fields, and adopt the pure scattered field formulation in order to obtain effective incident and scattered fields. With applications of the MRTD scheme, we construct the surface equivalent currents in the near-zone region and further derive the radar cross section (RCS) in the far-zone region for different scattering targets including perfectly electric conducting and lossy dielectric targets.
