摘要
介绍了卫星通信的特点及干扰的主要类型.上行信号受干扰的原因是转发器接收端没有区分合法与非法信号的能力.可通过抗干扰自动功率控制系统、频谱仪、上行功率判断干扰是否存在.对几种典型干扰进行了重点介绍.
This paper introduces the interferences in satellite communication. The uplink interference is due to the failure of transponder receivers to distinguish the legal and illegal signals. Anti-jamming automatic power control, spectrum analysis, uplink power are discussed.
