本文给出了以四喇叭为馈源,用等效抛物面原理设计隐蔽锥扫天线(以下简称CCSA)的计算机程序。用它能快速、精确地算出天线的方向图。因而便于设计、修改天线的几何参数。我们用此程序计算了某雷达天线的方向图,并与实测方向图比较,有良好的一致性。 In this paper, a computer program of concealed cone scanning antenna (hereinafter referred to as CCSA) is given by using four speakers as the feeding source and equivalent paraboloid principle. Use it to quickly and accurately calculate the antenna pattern. So easy to design, modify the antenna geometry. We use this program to calculate a radar antenna pattern, and compared with the measured pattern, there is a good consistency.
