卫星广播电视接收极化方式的正确使用

Right Use of Polarization in Satellite TV Reception

介绍极化的基本概念.极化分为线极化波和圆极化波两种,其中线极化波又分为水平和垂直两种极化波,圆极化波又分为左、右旋圆极化波.阐述了圆极化馈源对各种极化波的接收和线极化馈源对卫星发射线极化波的接收两种方法、技巧.

This paper introduces the basic concept of polarization.Polarization is divided into line polarization wave and round polarization wave.Line polarization wave includes level and vertical polarization wave.Round polarization wave includes levorotatory and dextrorotatory round polarization wave.It expounds the skill and two methods of the feed's reception of various polarization waves and the line polarization feed's reception of satellite sending line polarization wave.
