Abstract: A measuring system for determining a filling volume of a filling material in a container comprises a 3D camera and a radar-based fill-level measurement device. The 3D camera is used to initially record at least one 3D image of at least one partial region of the empty container interior. Based on the 3D images, a data set or a digital spatial model is created by which at least such partial region the geometry of the empty container interior is represented. To create the required, three-dimensional surface or level profile, the fill-level measurement device is based on a principle of digital beam shaping, such as the MIMO principle. Thus, based on the data set reflecting the geometry in the container interior and based on the fill-level profile, the filling volume in the container can be determined.

Based on the second received signal potentially another fill level value can be determined. In this way, the fill level measuring device can be adapted as regards frequency band to the particular application. The ascertained fill level can be checked for plausibility by comparing the fill level values ascertained in different frequency bands.

Abstract: Disclosed is a fill-level measuring device for determining the fill level in a container. The device comprises: a radar module for determining a distance to the surface of the filling material; a 3D camera for capturing at least one region of the surface of the filling material; and an evaluation circuit that is designed to measure a maximum distance and a minimum distance from the captured distance values and to determine the fill level on the basis of the distance, providing that the distance is smaller than the maximum distance value and greater than the minimum distance value. As a result of the redundancy or the verification provided by the 3D camera of the distance calculated by the radar module, the fill-level measuring device according to the invention is therefore more reliable with regard to the miscalculation of an incorrect fill level.

Abstract: The invention relates to a frequency converter circuit for a radar-based distance-measuring device. The core of the frequency converter circuit is a non-linear, high-frequency component, having a frequency connection point and a signal connection point, which serves as a signal input for a low-frequency input signal. On the reception side, the frequency converter circuit comprises at least one receiving antenna for receiving the high-frequency reception signal and a non-linear semiconductor component for downconverting the high-frequency reception signal.

Furthermore, the high-frequency reception signal is downconverted into a low-frequency evaluation signal, whereby the further determination of the distance can be performed on the basis of the low-frequency evaluation signal, which can be processed more easily.
