The basis of airborne millimeter wave imaging microwave radiometer antenna scan-
ning system, the selection of controlling motor and the balancing weight of antenna are in-
troduced. The scanning accuracy is improved by adopting structures of master-slave com-
puter and zero-detecting. The system is simplified and easy to be controlled by selecting a
small step angle and high precision step by step motor. It also overcomes the problem of
step displacement by adopting balancing weight measure of deviate spindle set and there-
fore increases the scanning precision.
