High-Frequency RCS of Perfectly Conducting or Coated Complex Objects in Real Time
Juan Manuel Rius, Merce Vall-llossera, Angel Cardama · 1991
This paper present a new and original approach to compute high-freqency radar cross section (RCS) of complex radar targets in real time using a 3-D graphic workstation. The aircraft is modelled with I-DEAS solid modeling software using a parametric surface approach. High-frequency RCS is obtained through Physical Optics (PO), Method of Equivalent Currents (MEC), Physical Theory of Diffraction (PTD) and Impedance Boundary Condition (IBC). Multiple scattering between target surfaces is also considered.
