电磁波极化的应用

Applications of electromagnetic wave polarization

极化是电磁波的一个重要参量,是电动力学、电磁场与电磁波课程教学中的重点内容之一.系统介绍电磁波极化这一概念在通信、雷达和抗干扰等方面的应用,即利用电磁波极化实现无线电信号的最佳发射和接收,利用极化提高通信容量,探讨了电磁波极化在雷达目标识别、检测、成像以及抗干扰中的应用.

Polarization is not only an important parameter of the electromagnetic wave but also a key concept in the electrodynamics and the electromagnetic field and wave courses. In this paper, applications of this concept in communication, radar and anti-jamming are introduced. By utilizing the characteristic of polarization, the optimal radio signal transmission and reception are achieved and the communication capacity is improved as well. The applications of polarization in the radar target recognition, detection, imaging and anti-jamming are discussed.
