Short summary
In this contribution, a radar system for measuring the height profile of bulk solids in silos, is presented. By utilizing six integrated radar chips, a compact 3D imaging radar system with an novel fractal antenna layout is realized. The performance of the system has been evaluated by test measurements on a sand heap, showing an improved measurement accuracy compared to conventional radar level systems.
