In this way intermediate-frequency values that are identical to those of an ideal sensor can be derived.

摘要： Described is a method for automatically initiating an update of a parasitic echo storage device in a fill level meter operating according to a runtime method. In this method individual echoes of echo curves of different ages are allocated, according to their typical echo characteristics, to global echo groups so that subsequently, after examining the behaviour over time of the echoes of the respective global echo curves, it can be judged whether the echoes of the respective global echo curves are useful echoes or parasitic echoes. Starting from this classification, the parasitic echo storage device is then updated with the oldest echoes of the corresponding global echo groups. Apart from the method for updating a parasitic echo storage device described is also an evaluation device for implementing the method as well as to a computer program and a computer program product for carrying out the method.

摘要： The shape or amplitude of reference pulses in a filling level radar typically depend on the component quality of the circulator used, of a transmitting/receiving coupler, or else of the circuit temperature. In case of large echoes at close range, the quality of the measurement may deteriorate. A radar module for extracting a reference signal for a filling level radar comprises a tap extracting the reference signal and a delay line delaying the transmit signal. Delaying the transmit signal on its way to the antenna takes place after the extraction of the leakage pulse.

摘要： For safety reasons the potential of an electrical supply line of a radar sensor should be separate from the potential of the filling level container. An arrangement for potential separation for a filling level radar is provided, which arrangement comprises a separation element for insulating the waveguide from the antenna. The separation element, corresponding to the cross section of the waveguide, is ring shaped. In this way rotatability between the sensor housing and the antenna subassembly is provided without influencing the signal line between the antenna and the waveguide.
