摘要
ＧＲＥＣＯ（Ｇｒａｐｈｉｃａｌ Ｅｌｅｃｔｒｏｍａｇｎｅｔｉｃ Ｃｏｍｐｕｔｉｎｇ） 技术是目前分析高频区复杂目标雷达散射截面（ＲＣＳ） 最有效方法之一．对复杂目标而言，应用ＧＲＥＣＯ方法的一个重要工作就是对目标的几何造型进行准确地建模，才能获得令人满意的结果．文中结合ＣＲ样条建模理论，阐述了在Ｗｉｎｄｏｗｓ ＮＴ环境下利用ＶＣ＋＋ ４．０ 与ＯｐｅｎＧＬ为ＧＲＥＣＯ方法进行建模的机制．以标准体与复杂目标为实例，给出了与实验结果符合良好的ＲＣＳ曲线。
GERCO(Graphical Electromagnetic Computing) is recognized as one of the most valuable methods for computing the high frequency RCS (Radar Cross Section). To the complex radar targets, in order to obtain a satisfying result, the target geometry fitting is an important work in applying the GRECO method. This paper shows the principle method by using Catmull Rom spline function geometry fitting theory, Visual C++ language and OpenGL in Windows NT system. It gives the RCS curves of a standard body and a complex radar target, which are satisfying measured results. The results can have practical engineering worth.
