摘要
极化信息在通信、导航、雷达等领域的应用越来越广泛,研究电磁波极化状态是研究、利用极化信息的前提和基础。椭圆极化是电磁波最基本的极化形式,线极化和圆极化是其特殊形式。从最普适的椭圆极化形式入手,导出了两种退化的极化形式:线极化和圆极化;阐明了三种极化波的解、合关系;推导了极化椭圆的参数与电磁波参数的关系;证明了极化方向与电磁波在水平垂直极化基下两分量相对相位的关系以及静态空间极化。
The application of polarization information in the field of communication, navigation and radar systems has been becoming more and more widely, the research on polarized information and its utility is based on the study on polarized state of electromagnetic wave. By starting with the universal elliptical polarized form, two degeneration forms of which ： linear polarized form and circular polarized form, are deduced. The decomposition and composition relations of the three types of polarization wave are clearly expoundsed. The quantity relationship of parameters of polarized ellipse with that of electromagnetic wave is given. The relation between polarization direction and electromagnetic phase is proved out, as well as static space polarization.
