Abstract: A method of determining a temporal position of a received signal within a sample series is disclosed. The method includes sampling a sensor at a sampling frequency to generate the sample series. A matched filter set of matched filters is applied to the sample series to generate a matched filter correlation set of matched filter correlations, wherein impulse responses of respective matched filters correspond to a template signal at the sampling frequency of the sensor shifted by a sub-interval shift. The matched filter correlations are evaluated to determine a received signal sub-interval shift. The temporal position of the received signal within the sample series is determined based on at least the received signal sub-interval shift.

Abstract: The present disclosure relates to a radar device including a first radar-IC for processing first receive signals from first antennas of an antenna array, wherein the first radar-IC is configured to determine a first range-Doppler map based on the first receive signals, and to determine a first subregion of the first range-Doppler map based on criteria of interest. The radar device also includes at least a second radar-IC for processing second receive signals from second antennas of the antenna array, wherein the second radar-IC is configured to determine a second range-Doppler map based on the second receive signals, and to determine a second subregion of the second range-Doppler map based on the criteria of interest. A data interface is configured to forward information indicative of the first and/or the second subregions to a common processor for further processing.

Abstract: A method for a radar device is described below. According to an example implementation, the method comprises transmitting an RF transmission signal that comprises a plurality of frequency-modulated chirps, and receiving an RF radar signal and generating a dataset containing in each case a particular number of digital values based on the received RF radar signal. A dataset may in this case be associated with a chirp or a sequence of successive chirps. The method furthermore comprises filtering the dataset by way of a neural network to which the dataset is fed in order to reduce an interfering signal contained therein. A convolutional neural network is used as the neural network.

Abstract: The description below relates to a method for a radar system that can be used to detect perturbations in the received radar signal. According to an example implementation, the method comprises providing a digital radar signal using a radar receiver, wherein the digital radar signal comprises a multiplicity of segments; calculating an envelope signal that represents the envelope of a segment of the digital radar signal; and ascertaining a time of the onset of an interference signal contained in the considered segment of the digital radar signal by using at least one statistical parameter of the envelope signal.

Abstract: A radar method is described herein. In accordance with one embodiment the method includes receiving a plurality of chirp echoes of transmitted radar signals, generating a digital signal based on the plurality of chirp echoes, and calculating a range map based on the digital signal. The range map includes a plurality of values, each value is represented by an amplitude value and a phase value, and each value is associated with one frequency bin of a set of frequency bins and one chirp echo of the plurality of chirp echoes. The method further includes identifying chirp echoes which are affected by interference and determining, for one or more selected frequency bins, corrected phase values based on phase values that are associated with chirp echoes not identified as affected by interference.

Abstract: A method for the use in a radar system comprises: receiving an RF radar signal; down-converting the received RF radar signal into a base band using a frequency-modulated local oscillator signal including a scanning chirp having a higher bandwidth than a regular chirp bandwidth; generating a digital base band signal based on the down-converted RF radar signal, the digital base band signal including a sequence of samples associated with the scanning chirp; identifying, in the sequence of samples, impaired samples, which are affected by interference; and selecting—based on the position of the impaired samples within the sequence of samples—a sub-band, which has the regular chirp bandwidth, for transmitting chirps of chirp frame used for measurement data acquisition.
