Abstract
An azimuth drive for a radar array comprises at least one circular track mounted to a wheel on which the radar array is mounted. A motor is coupled to the at least one circular track and capable of moving along the track in the tangential direction, to relocate the center of mass of the wheel on which the radar array is mounted.
Claims31
An azimuth drive for a radar array, comprising:
- at least one circular track mounted to a wheel on which the radar array is mounted;
- a motor that is coupled to the at least one circular track and capable of moving along the track in the tangential direction, thereby to relocate the center of mass of the wheel on which the radar array is mounted.
An azimuth drive for a radar array, comprising:
- at least one circular track mounted to a wheel of an array assembly that includes the radar array;
- and
- a motor that is coupled to the at least one circular track and capable of moving along the track in the tangential direction, thereby to relocate the center of mass of the wheel of the array assembly.
A radar system, comprising:
- a radar array mounted on a wheel;
- at least one circular track mounted to the wheel;
- a motor that is coupled to the at least one circular track and capable of moving along the track in the tangential direction, thereby to relocate the center of mass of the wheel on which the radar array is mounted, causing the wheel to roll along a path on a platform under operation of gravity and revolve about the platform.
A method for driving a radar array in the azimuth direction, comprising:
- (a) moving a weight to relocate a center of mass of a wheel on which a radar array is mounted;
- (b) allowing the wheel to roll under operation of gravity;
- and
- (c) guiding the wheel to revolve around a platform, thereby to adjust the azimuth position of the radar array.
