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 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...
