Abstract :
In this paper, Ludwig´s algorithm is improved to compute the target´s radar cross section (RCS). The target is modeled with non uniform rational Bezier surface (NURBS), so the integral needed to be calculated is different to that based on triangle facets. The author modified Ludwig´s algorithm to evaluate the integral, the result in this paper shows that the new formula is valid.
