| Abstract: | Visualization in prediction of RCS is based on the classic high-frequency techniques. Ituses 3-D graphics hardware acceleration to identify the surfaces of the target, which is visible fromthe radar vieWpoint, and to obtain the six-dimension geometric information at each point of these surfaces. The targets-modeling is based on NURBS surfaces. The high-frequency RCS is obtainedthrough Physical Optics (PO), Physical Theory of Diffraction(PTD)and Impedance Boundary Condition (IBC) techniques. Some computational results are presented. |
