Abstract:
A new approach is presented to compute the high frequency radar cross section(RCS)of complex radar targets in real time, using a Personal Computer with a 3 D graphics hardware accelerator. This method implements a new technique called “Graphical Electromagnetic Computing(GRECO)”.The target is modeled with G 2 Catmull Rom(C R) geometric spline and the image of the target is rendered and displayed on the screen in real time using Phone illumination model and the 3 D graphics accelerator, and then the high frequency RCS can be computed through Physical Optics(PO),Method of Equivalent Currents(MEC),Physical Theory of Diffraction(PTD),and Impedance Boundary Condition(IBC) techniques.
Key words: GRECO, complex radar targets, electromagnetic scattering
