一、引言在文献[1]中,对天线罩的电气设计作了理论分析,给出了单层和夹层介质平板的透过系数和反射系数的解析表示式,成为天线罩设计者的重要参考书。但随着航空和航天雷达技术的发展,对天线罩电气性能要求愈来愈高,于是出现了多夹层(层数N≥5)结构线天罩。应用“多次反射概念”所获得的透过系数和反射系数的公式相当繁,相应的计算程序也很复杂。为解决这一问题,运用传输线理论,把多层介质平板等效为一个级联的四端网络,通过这个等
I. INTRODUCTION In the literature [1], the electrical design of the radome is theoretically analyzed, and the analytical expressions of the transmission coefficient and the reflection coefficient of the single-layer and interlayer dielectric slabs are given, which becomes an important reference for radome designers book. However, with the development of aeronautical and astronautical radar technology, the requirements on the electrical performance of the radome are getting higher and higher, so that a multi-sandwich (number of layers N≥5) line masks has emerged. The formula for the transmission coefficient and the reflection coefficient obtained by applying the “multiple reflection concept” is quite complicated, and the corresponding calculation procedure is also complicated. To solve this problem, the use of transmission line theory, the multilayer dielectric equivalent to a four-terminal network cascade through this
