摘要
采用非均匀有理B样条(NURBS)对复杂目标进行建模,利用Cox-DeBoor算法将NURBS曲线曲面转化为更适合数值计算的有理Bézier曲线曲面,采用后向面判别法处理不同面元间的遮挡问题,并给出导弹雷达散射截面的计算结果。
NURBS are used for modeling complicated objects. NURBS surfaces are subdivided into a combination of rational Bézier patches which are more suitable for numerical calculation with Cox-De Boor algorithm. Shadows between culling and RCS of missile is presented. different patches are handled through back-face
