过境卫星对广电专用卫星的干扰及应对措施

Interference and Response of Transit Satellite on Broadcast Television Special-purpose Satellite

作为广播电视信号三大传输手段之一的卫星传输技术,在当前仍然扮演着重要角色。卫星传输系统是一个开放系统,易受到外界信号的干扰。过境卫星干扰由于其具有隐蔽性、特殊性,给广播电视卫星传输带来许多不利影响。结合工作实际,通过介绍近年来发生的干扰实例,对过境卫星干扰的机理进行分析,提出减小干扰的有效措施,为同行提供一定的借鉴作用。

As one of the three broadcast television signal transmission method of satellite transmission technology, still plays an im- portant role in the current. Satellite transmission system is an open system, susceptible to interference from outside signals. Transit satellite interference because of its hidden nature, particularity, has brought many negative effects to the radio and television satel- lite transmission. In this paper, combined with the actual work, through the example of interference occurred in recent years, the mechanism of the transit satellite are analyzed, some effective measures are proposed to reduce the iuterferenee, and provide the reference for colleague.
