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.
