Gravity drive for a rolling radar array
First Claim
Patent Images
1. An azimuth drive for a radar array, comprising:
- at least one circular track mounted to a wheel on which the radar array is mounted, the wheel having an axle;
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 relative to the axle, wherein relocation of the center of mass of the wheel causes the wheel to rotate about the axle.

15. 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, the wheel having an axle; 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 relative to the axle, wherein relocation of the center of mass of the wheel causes the wheel to rotate about the axle.

16. 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. - View Dependent Claims (17, 18, 19, 20, 21, 22)
