In this contribution a novel radar positioning system is introduced. It makes use of a mathematical curve, called hypocycloid, for a slanting movement of the radar antenna. By means of a planetary gear, a ball, and a universal joint as well as a stepping motor, the two dimensional positioning is provided by a uniaxial drive shaft exclusively. The fundamental position calculation and different signal processing algorithms are presented. Measurements, that were carried out with an 80 GHz FMCW radar system are essential part of this contribution and will be discussed in detail.
