Abstract

A FMCW fill level sensor comprising an equalizer that equalizes the intermediate frequency signal digitalized by an analog-digital converter. Equalizing is carried out, for example, in the form of convoluting the digitalized intermediate frequency signal by an equalizing function in the time domain. It is also possible to equalize the digitalized intermediate frequency signal by multiplying the signal by an equalizing function in the form of a transfer function G(ωk) to form the discrete frequency in the frequency domain. A digital filter can also be used. This can increase the accuracy with which the fill level is determined.
