摘要
卫星通信是地球上无线电设备之间利用人造卫星作为中继站进行的通信。地球静止轨道(Geostationary Earth Orbit,GEO)通信卫星由于其相对地球静止的特性,被广泛应用于通信、气象、导航等领域。通信地球站是卫星通信的重要环节,准确调整接收天线的方位角、俯仰角和极化角是地面接收站有效进行通信的关键条件之一。结合线极化角的定义,研究了一种适用于地球静止轨道卫星通信的线极化角矢量计算方法,可用于指导卫星通信地球站接收天线的极化角调整。
Satellite communication is one kind of communications with artificial satellites between Earth radio equipments. Due to stationary characteristic relative to the Earth, the Geostationary Earth Orbit （GEO） communication satellites are widely used in the fields of communication, meteorology, navigation, etc. Communication ground stations play an important part in satellite communications. Accurate adjustment of azimuth angle, elevation angle and polarization angle for the receiving antenna is one of the key conditions to effective communication. With the definition of linear polarization angle, authors of this paper have presented a vector calculation method of linear polarization angle which is suitable for GEO satellite communications. The method can be used to provide guidance for polarization adjustment of antennas at the satellite communication ground station.
