Assignee: VEGA GRIESHABER
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A method for fill level measurement with a radar fill level measuring device using the following steps:
1. sending a transmission signal with a plurality of frequency ramps,
2. receiving a reception signal per frequency ramp of the transmission signals,
3. saving the reception signals in a memory,
4. performing a first spectral analysis of the reception signals,
5. determining distance of significant reflectors from the first spectral analysis of at least one reception signal,
6. performing a second spectral analysis of a plurality of output signals of the first spectral analysis at least at the position of one significant reflector in the reception signal,
7. determining speed values of significant reflectors from the results of th second spectral analysis, and
8. determinating a fill level echo.
