Radar system with a rotating antenna system

A radar antenna system comprises a wheel, cone or frustum having an axis. The wheel, cone or frustum has a circumferential portion adapted to engage at least one path disposed on a platform for revolving the radar array about the platform. A radar array is mounted on the wheel, cone or frustum, with the axis normal to a face of the radar array. The wheel, cone or frustum rotates about the platform as the radar array revolves around the platform during operation.
