摘要
ＧＲＥＣＯ技术是目前分析高频区复杂目标雷达散射截面（ＲＣＳ）最有效的方法之一。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，这样才能获得令人满意的结果。本文结合ＣＲ样条建模理论，利用（Ｇ１，Ｋ＝１）几何样条及其张量积曲面，阐述了在ＷｉｎｄｏｗｓＮＴ环境下利用ＶＣ４０与ＯｐｅｎＧＬ为ＧＲＥＣＯ方法进行建模的机制。
Graphical electromagnetic computing (GRECO) is recognized as one of the most valuable methods of computing the high frequency RCS. To the complex radar tragets, in order to obtain a satisfied result, the target geometry fitting is an important task in applying the GRECO method. This paper shows the principle method using the Catmull Rom spline fitting theory, Visual C language and OpenGL in Windows NT.
