Abstract: A radar fill level measurement sensor for measuring the level of material in a container, includes a transmit/receive circuit that transmits an electromagnetic pulse, and detects reflected electromagnetic pulses and provides an intermediate frequency signal indicative of the reflected electromagnetic pulses. A logarithm detector circuit receives the intermediate frequency signal and provides a logarithmic output signal indicative of the logarithm of the intermediate frequency signal. An evaluation unit receives and processes the logarithmic output signal, to determine the fill level of the material within the container, and provides a fill level measurement signal indicative thereof.
