| 447 | METHOD FOR FMCW-BASED DISTANCE MEASUREMENT IN WAVEGUIDES | US16360150 | 2019-03-21 | US20190293757A1 | 2019-09-26 | Alexey Malinovskiy; Harald Faber |
| The present disclosure relates to a method for FMCW-based measurement of a distance of an object located in a waveguide, as well as a corresponding distance measurement device that, in particular, may be used for fill-level measurement in surge pipes or bypass pipes of containers. The method is based upon the fact that the transmission signal that is typical in FMCW is not ramp-like, and thus is emitted with constant frequency modulation. Rather, according to the present disclosure, a curvature of the frequency ramp is set to be at least approximately proportional to the frequency dependency of the propagation velocity of the transmission signal in the waveguide. The distortion effect is thus compensated for in that the propagation velocity of the transmission signal in waveguides is not constant, but, rather, decreases with falling transmission frequency. | ||||||

| A method for measuring fill level of a fill substance. Transmission signals are sent and their fractions reflected on reflectors in the container and received as received signals. Based on the received, echo functions are derived and wanted echos of predetermined wanted echo types respectively contained in the echo functions and identifiable based on predetermined echo recognition methods are ascertained. Each wanted echo is a local maximum and is attributable to a reflection on a reflector associated with its wanted echo type. Echo quality of each wanted echo is determined. The echo quality is higher, the more peak shaped the echo function is in the region of the respective wanted echo, and the fill level is determined taking into consideration echo qualities of the wanted echos. | ||||||

| A nuclear level sensing gauge for a vessel 10 comprises a vertical source well 12 and one more level sensing detectors 22 mounted to vertically spaced nozzles, where the sources 30 in the source well 12 are distributed sources which emit a radiation pattern illuminating a length of greater than one inch of the respective level sensing nozzle, so that thermal expansion or contraction of the vessel 10 does not significantly alter radiation illuminating each detector 22.
