Abstract: A radar sensor for use within a vehicle includes self calibration functionality for performing angle calibrations for the sensor when the sensor is mounted within the vehicle. In at least one embodiment, the radar sensor collects information on stationary infrastructure around the vehicle for use in calibration operations. The infrastructure information may be used to generate a Doppler Monopulse Image (DMI) or other graph for the sensor. A clutter ridge within the DMI or other graph may then be analyzed to determine calibration data for the sensor.

Abstract: The present invention relates to a method for separating transmitted signals in radar systems and an associated radar system. In the method, the signals for transmission are shared among multiple subcarriers by means of OFDM, which subcarriers are assigned to the transmitting antennas according to a distribution scheme. In this distribution scheme, each subcarrier is assigned to one transmitting antennas only. The subcarriers assigned to a given transmitting antenna are spread over the entire signal bandwidth. In this way, very high dynamics may be achieved while retaining complete orthogonality of the signal paths.

Abstract: The present invention relates to a method and also a device for digitally processing OFDM signals which are emitted by a transmission apparatus with modulation symbols as information carriers, reflected at one or a plurality of objects at least to some extent and received by a receiving apparatus. The modulation symbols are extracted without prior channel equalisation from the OFDM signals received and the extracted modulation symbols are normalised by a complex division to the respectively transmitted modulation symbol. The radar analysis for determining the distance and/or determining the speed of the objects then takes place on the basis of the normalised modulation symbols. With the method and the device, on the one hand, both distance and speed of the objects can be determined independently of one another. On the other hand, the method works very reliably, as it is not influenced by the transmitted information.

Abstract: An apparatus for producing large stitched products has a multiple needle stitching unit, a storage device, and a processing station. The multiple needle stitching unit has a large number of stitching elements and a guide device which is arranged in the region of the stitching elements and movable in relation to the stitching elements in a direction substantially perpendicular to the conveying direction of the stitched product. Between the multiple needle stitching unit and the processing station is a device for compensating for an annular offset of the stitched product between an output of the guide device and an input of the processing station.
