Abstract: An FMCW-radar based distance measuring device is characterized in that, in addition to analogue high-pass and low-pass filtering, the evaluation signal typical for FMCW additionally undergoes subsequent digital filtering. In this case, the analogue/digital conversion takes place by oversampling. As a result, according to the invention, all those frequencies in the evaluation signal that are above or below the frequency corresponding to the distance of the object are effectively suppressed. At the same time, the analogue filters can be constructed with a very low level of complexity. The space requirement and the costs of the analogue components is reduced thereby. In addition, the dependence on temperature of the distance measuring device is reduced thereby. The potentially high distance resolution is also maintained.

Abstract: In an FMCW-based fill-level measurement device, the fill-level value can be compensated with regard to component tolerances. A diagnosis unit of the fill-level measurement device compares the clock rate of the signal-generating PLL with the sampling rate of the analog/digital converter and determines a first compensation factor. With the aid of the first compensation factor, the determined fill-level value can be compensated with regard to these sampling or clock rates without any external high-precision reference source having to be used for this purpose.

Abstract: An FMCW-based fill-level meter comprises a signal generating unit for generating the ramp-shaped signal; an antenna for transmitting the signals towards the contents and for receiving the corresponding received signal; a signal processing unit which generates a frequency spectrum of the analysis signal per measurement cycle according to the FMCW principle; and a control/analysis unit to determine the distance using the frequency spectrum. The fill-level meter is characterized in that a frequency band and a measurement range can be specified, and on the basis thereon the fill-level meter can autonomously set or change the threshold frequencies and/or the ramp gradient. This is advantageous is that the use location of the fill-level meter is not limited to specific regions, such as China, the USA, or Europe, after being manufactured.

Abstract: The invention relates to an FMCW radar-based distance meter by means of which the distance to an object can be reliably determined. The distance meter comprises at least: a signal generation unit for generating corresponding high-frequency signals; an HF antenna for transmitting and receiving the radar signals; and an evaluation unit typical for FMCW. The evaluation unit includes an additional averaging stage that averages the intermediate-frequency signal in the signal direction over time before the frequency spectrum is created. This significantly improves the signal-to-noise ratio of the intermediate-frequency signal. Overall, the correct maximum in the frequency spectrum, said maximum representing the distance, can thus be determined in a significantly more reliable manner.

Abstract: Disclosed is a method for detecting an event-based state, such as foam formation or a working stirring mechanism in a container during a radar-based measurement of a fill level of a filler located in a container. The method includes: generating an analysis curve and detecting a specified characteristic value of the analysis curve within at least one specified sub-region of the measurement region. The characteristic value can be the amplitude of a local maximum or the area under the analysis curve for example. A change or a dispersion of the characteristic value is ascertained over proceeding measurement cycles. The fill level measuring device detects the event-based state if the change or the dispersion exceeds a corresponding threshold. Thus, the occurrence of different events in the container can be imparted to a system controller automatically and without additional measurement instruments.

Abstract: Disclosed is a method for a radar-based fill level measurement according to the pulse transit time method. Also disclosed a fill level measuring device for carrying out said method. On the basis of an evaluation signal, the relation between the clock rate and the sampling rate, and a predefined target relation, an evaluation curve is generated. The fill level is thereby determined on the basis of said evaluation curve. The evaluation curve is generated by means of temporal expansion or compression of the evaluation signal, wherein the compression or the expansion is carried out as a function of a ratio between the measured relation and the target relation. Any deviation of the sampling rate from the setpoint value of the sampling rate, for example due to faulty control, is compensated. Thus, the potentially attainable accuracy of the fill level measurement is increased due to the invention.

Abstract: A method for checking the functional ability of an FMCW-based fill-level measuring device, which serves for measuring the fill level of a fill substance located in a container, as well as to a fill-level measuring device suitable for performing this method. For checking the functional ability, a microwave signal is produced, whose frequency change differs from the frequency change of the measurement signal used during regular measurement operation. By comparing the frequency of the difference signal resulting from the microwave signal with a predetermined reference frequency, it is ascertained, whether the fill-level measuring device is functionally able. Thus, the fill-level measuring device detects, independently, whether it is functionally able, or whether an error is present, caused principally by device-internal disturbance signals. This offers, especially, a clear advantage as regards meeting safety standards for the field device.
