Radar fill level measurement device and method for operating a radar fill level measurement device

A radar fill level measurement device for determining a fill level of a medium, the radar fill level measurement device comprising:

• 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,
• wherein the radar fill level measurement device is configured to vary a transmitting power of the transmission signal,
• wherein the controller is further configured to determine a current transmitting power of the transmission signal,
• wherein the controller is further configured to vary, based on the determined current transmitting power, a value of the at least one evaluation parameter, such that the fill level is determined taking into account the transmitting power,
• wherein the at least one evaluation parameter includes a threshold value for an amplitude of at least one measurement signal that correlates with the reception signal, and
• wherein the controller is further configured to vary the threshold value based on the determined current transmitting power.
