二十多年来卫星信号传播在我国广播电视事业中的到了蓬勃发展和广泛应用,并在现代社会中发挥这重要作用。卫星广播具有点到面覆盖特点,提供了对我国国土全部覆盖的能力,为我国广播电视工业的发展开辟了一个新纪元。但在卫星传播信号传输过程中常会受到许多因素的干扰,有些干扰甚至很难进行解决。因此,本文主要从广播电视卫星信号传播的主要干扰因素入手进行分析,重点就抗干扰技术进行探讨。
Over the past 20 years, the satellite signal has been booming and widely used in China’s radio and television industry and has played an important role in modern society. Satellite broadcasting has the characteristics of point-to-area coverage and provides the full coverage of our country’s land capacity, which has opened up a new era for the development of China’s radio and television industry. However, many factors often interfere with the transmission of signals transmitted by satellites. Some interferences are even difficult to be solved. Therefore, this article mainly analyzes the main interference factors of radio and television satellite signal transmission, and focuses on the anti-interference technology.
