This paper introduced the scanning mode of microwave imager, analyzed the scanning motion of the microwave imager and its influence on the attitude stability of the satellite, and proposed the static balance of the antenna in scanning motion stability control, the precision of antenna deployment, the dynamic balance of rotating body and The overall dynamic balance of state control methods. The scanning equilibrium state of the microwave imager and the on-orbit verification result are given. The results show that the dynamic balance control of microwave imager is effective and the desired control of attitude stability is achieved.
