ABSTRACT:
An azimuth drive for a radar array comprises an electromagnetic track mounted to a wheel on which the radar array is mounted; and a magnetized carriage assembly operatively coupled to the electromagnetic track and capable of moving along the track in a tangential direction in response to electromagnetic force from select portions of the track to thereby relocate the center of mass of the wheel on which the radar array is mounted, wherein a moment produced from relocation of the center of mass is used to rotate the wheel.
