| 摘 要： | 复杂的卫星上具有众多的发射和接收频率,有时会发生不同信道之间的串扰和干扰现象。此种干扰问题如果不解决,会严重阻碍卫星研制任务的进展和造成很大损失。文章从卫星系统设计的观点出发分析研究此种干扰现象的机理,并给出一个防止干扰发生的简易快速设计方法。

| Abstract: | On the complex spacecraft with many transmitting and recei-ving frequencies,sometimes the complicated phenomena of RF intermodu-lation interference in the transmitter group and disturbance to the onboardreceivers would occur.Those problems,which cause troubles and can not besolved easily,will hinder the development of the spacecraft.From thepoint of view of spacecraft system designing,this paper studies the mecha-nism of those phenomena,gives a simple,effective and very fast designmethod for prevention from those problems. |
