Abstract

A radar fill level measurement device for determining a fill level of a medium is provided, including a transmitter configured to transmit a transmission signal towards the medium; a receiver configured to receive a reception signal reflected by the medium; and a controller configured to determine the fill level of the medium based on the reception signal and based on at least one evaluation parameter, the radar fill level measurement device being configured to vary a transmitting power of the transmission signal, the controller being further configured to determine a current transmitting power of the transmission signal, and the controller being further configured to vary, based on the determined current transmitting power, a value of the at least one evaluation parameter and/or at least one measurement signal that correlates with the reception signal, such that the fill level is determined taking into account the transmitting power.
