ANALYSIS OF ELECTROMAGNETIC CHARACTERISTICS OF 3-D MEDIA RADOME BY COMPLEX ASTIGMATIC WAVE THEORY
-
摘要: 复象散波理论是一种分析三维介质雷达罩电磁特性的有效方法。本文以椭球夹心状的雷达罩为例,将其数值结果以三维立体方向图的形式给出,并与实验结果比较,说明这种方法可有效地简化介质雷达罩的分析、计算及优化设计。

Abstract: The complex astigmatic wave theory is used to analyse the electromagnetic characteristics of 3-D radome. A number of calculations for the ellipsoidal sandwich radome are performed, and the stereoscopic graphics are constructed. Comparing with the experimental results, it is shown that this method can be used to simplify the optimization designs for some kinds of 3-D radomes. -
