| Abstract: | This paper deals with the mechanical scanning and momentum compensation device of multi-frequency microwave radiometer antenna carried in astrovehicles. In order to keep flight attitude accuracy of astrovehicles, the dynamic interference resulting from swinging motion of antenna must be eliminated Compensating mass is attached to this system to achieve this goal. The paper sets up the objective function for the minimization of the remaining momentum of the system after compensation, then adopts complex method to optimize design parameters of the device. Tests gave satisfactory results. |
