The proposed two-speed system for driving a radar antenna contains a selsyn transmitter, a selsyn receiver connected to the selsyn transmitter, an amplifier, and a driving motor with a gear. The output of the selsyn receiver is connected to the input of the amplifier. The motor is connected to the output of the amplifier. The shaft of the selsyn transmitter and the shaft of the motor are coupled with the corresponding shafts of the gear. Additionally, for the purpose to increase the accuracy, the system contains the second selsyn transmitter, the second selsyn receiver, the second gear, and a unit for interfacing the system to a computer.
