Zusammenfassung:Disclosed is a method for detecting a faulty state of an FMCW-based fill level measuring device. For this, a correlation coefficient is ascertained by correlation, especially cross correlation, of the measurement signal with a reference signal. The faulty state is accordingly detected when the correlation coefficient subceeds a predefined minimum value. In this way, the functioning of the fill level measuring device can be monitored with a degree of safety allowing the fill level measuring device to be applied also in process plants and measuring environments, which require extremely reliable measuring apparatuses, and measurement data.
