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...
In this paper, the method of moment (MoM) is used to investigate the characteristics of the GPS (Global Positioning System) signal scattering from the rough sea surface under low grazing incidence, and then on the basis of the results, the GPS signal could be received as the initial field by the improved Discrete Mixed Fourier Transform algorithm (DMFT) method to study the propagation characteristics...
To fast calculate the radar cross section (RCS) of an arbitrarily shaped three-dimensional (3D) perfect electric conductor (PEC) body over a frequency band, the method of moments (MOM) in conjunction with the general asymptotic waveform evaluation (GAWE) is applied in this paper. And the 3D body is modelled by the non-uniform rational B-spline (NURBS) surface through the compute aided geometric design...
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...
