摘要： A FMCW fill level sensor comprising an equaliser that equalizes the intermediate frequency signal digitalised by an analogue-digital converter. Equalising is carried out, for example, in the form of convoluting the digitalised intermediate frequency signal by an equalising function in the time domain. It is also possible to equalise the digitalised intermediate frequency signal by multiplying the signal by an equalising 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.

摘要： A fill level measuring device designed for the generation and emission of a transmission signal, wherein the transmission signal includes at least one frequency ramp. In order to determine the level of a filling material in a vessel, only frequencies within a fundamental frequency interval are used. In this case, the minimal frequency of the fundamental frequency interval is greater than the minimal frequency of the frequency ramp and/or the maximal frequency of the fundamental frequency interval is smaller than the maximal frequency of the frequency ramp. The approach provides a reduction of power peaks in the frequency spectrum of the mean power of fill level measuring devices, which peaks result from times in which the fill level measuring device emits a constant frequency before the beginning of or after a frequency ramp.

摘要： A level radar is switchable between pulsed and FMCW radar methods. For example, the radar device may include two separate front ends which can be activated selectively via a logic control system. Upon switching to the respective other measurement principle, the evaluation software is also adapted accordingly. In this way, it is possible to use advantageous properties of both measurement methods in a targeted manner.
