介质共形顶相控阵天线利用变厚度介质透镜改变相控阵波束扫描方向,理论上来说可到达半空域或更大,是一种适用于弹载、机载雷达系统的天线。本文较详细地讨论了介质罩对电磁波的发散系数的计算,给出了分析非平面变厚度分层介质对电磁波反射、折射的两种有效方法,并进行了比较。
Medium conformal top phased array antenna using variable thickness dielectric lens to change the phased array beam scanning direction, in theory, can reach the semi-airspace or greater, is a suitable antenna for airborne, airborne radar systems. In this paper, the calculation of the divergence coefficient of the electromagnetic wave by the dielectric cover is discussed in detail. Two effective methods of analyzing the reflection and the refraction of the electromagnetic wave by the non-planar and variable thickness layered medium are given and compared.
