Radar systems not only allow the measurement of speeds and distances, but can also be used for the contactless measurement of various parameters of the target. These include, for example, the layer thickness of workpieces and foils, but also the continuous monitoring of vibrations of machines in operation. This allows deviations from normal operation to be detected at an early stage to avoid outages and damages.
An open access article by Fabian Michler, Benedict Scheiner et. al. in the new IEEE Journal of Microwaves explains the basics of cutting-edge radar-based measurement technology and features some exciting applications.
