Parallel NURBS PO method based on the Ludwig algorithm and its application to the RCS computation
This paper applied parallel computation technique on the radar cross section (RCS) prediction. Nonuniform rational B-spline (NURBS) surfaces modeling technique is applied in target description. Modified Ludwig algorithm is adopted to calculate the integral of the induced current on the rational Bezier surface. The parallel computation technique is applied to accelerate the computational speed. Numerical example is also given to verify the efficiency of this method.
