Abstract :
The non-uniform rational B-spline (NURBS) model is constructed based on the data points on the surface of a target, and the B-Spline basis functions are analyzed. The radar cross section (RCS) is calculated with the physical optics (PO) and LUDWIG integral method based on NURBS models, which verifies the validity of the modeling method mentioned in this paper.
