Method for measuring fill levels

Abstract

Method for fill level measurement with a radar fill level measuring device using the following steps: sending a transmission design with a plurality of frequency ramps, receiving a reception signal per frequency ramp of the transmission signal, saving the reception signals in a memory, performing a first spectral analysis of the reception signals or performing a second spectral analysis of the reception signals, carrying out a second spectral analysis of several output signals of the first spectral analysis at the location of at least one significant reflector in the reception signal or performing a first spectral analysis of several output signals of the second spectral analysis, determining the distances of significant reflectors from the results of the first spectral analysis, determining the fill level echo based on the previously determined information.
