Fast RCS Computation over a Frequency Band based on General Asymptotic Waveform Evaluation: Geometric Modelling by NURBS surface
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 (CAGD). Numerical simulations of a square plate and a sphere are shown. Good agreements between the GAWE and the exact solutions obtained by MOM are illustrated. And the GAWE is more effective in computing the RCS over a frequency band. It is necessary to note that the MOM in conjunction with the GAWE technique can be also applied to predict the mono-static RCS of an arbitrarily shaped 3D PEC body.
