An approximation iterative model based on the equivalence principle is described for predicting the bistatic normalized radar cross section of a rough homogeneous layer made up of two rough surfaces.
The purpose of this study is to describe a new hybrid method based on the reciprocity theorem, the physical optics (PO) and the Kirchhoff approximation (KA) for calculating the composite electromagnetic scattering from a target above a one-dimensional rough interface. The KA method is used to investigate characteristics of electromagnetic scattering from the rough interface (including the equivalent...
To investigate the electromagnetic (EM) scattering from a PEC target located above a two-layered rough surface, the method of moments (MOM) is introduced in this paper. The incident wave is considered in the vertical polarization. The discrepancies of the bistatic scattering from this composite model and two-layered rough surface only are shown firstly. The influences of the relative permittivity...
MPI-based parallel FDTD algorithm for the electromagnetic scattering from two-layered randomly rough surfaces is presented in the paper. And the uniaxial perfectly matched layer (UPML) medium is adopted for truncation of FDTD lattices, in which the finite-difference equations can be used for the total computation domain by properly choosing the uniaxial parameters. This makes the parallel FDTD algorithm...
