Concept for a fast tracking 60 GHz 3D-radar using frequency scanning antennas

This paper discusses the system concept for a compact three dimensional (3D) millimeter wave radar system for tracking fast moving objects with low radar cross section (RCS). The concept contains two orthogonally arranged two dimensional (2D) scanning radar frontends operating in a fast time-multiplexed mode. The 2D scanning is achieved by FMCW based operation of frequency steering meander-line antennas, which allow very fast generation of 2D scans of the monitored area. Both 2D scans are then combined into a three dimensional representation of the monitored area and therefore the tracking of fast moving objects in single target scenarios is possible.
