摘　　要：提出了利用图形电磁计算方法进行赋形反射面天线的设计。利用NURBS对任意的赋形反射面天线进行建模,通过改变控制点改变模型局部的形状,易于对相位优化,在设计过程中实时的对测试结果进行监控,随时对反射面天线进行调整,以接近设计指标;自动完成对抛物面天线的精密剖分;在抛物面天线方程不知的条件下,易于通过光照获得表面法矢。The method of combining GRECO （Graphical Electromagnetic Computing） to design shaped-beam reflect antenna containing single feeding source is first proposed. Shaped-beam reflect antenna in random shape is able to be designed easily by using NURBS （ Non-uniform Rational Basic Spline）, and the shape of a little part is able to be changed by changing the controlling points, so the phase of the reflect antenna is easily to be controlled to reach the best result. The reflect antenna is able to be divided into fragmentary parts automatically. By setting the fitting light model and light sources, the normal of the surface of the antenna is able to be gained in the case of not knowing the expression of the reflect antenna.
