This paper presents a measurement method using Synthetic Aperture Radar (SAR) for the surveillance of bulk materials moving on a conveyor belt. As this concept has to be suitable for realtime monitoring in industrial facilities, the signal processing is able to calculate more than ten SAR images per second. This is achieved using the efficient backprojection algorithm and appropriate shifting of the image area. The velocity of the belt is determined in advance by high precision corner reflector measurements. Additionally, this paper displays results from measurements performed by the presented measurement systems using a Frequency Modulated Continuous Wave (FMCW) radar sensor at 144 GHz to prove the suitability for the desired purpose. © 2019 IEEE.
