Abstract: According to at least one embodiment, a MIMO radar arrangement includes a radar receiver configured to generate radar reception data from radio receive signals received by a plurality of radar receive antennas. The arrangement further includes one or more signal processors configured to: generate frequency domain data for a range-Doppler bin based on the radar reception data and determine one or more peaks from the generated frequency domain data. The radar arrangement further includes a trained machine learning module configured to generate, using frequency domain data corresponding to each of the of the one or more determined peaks as input, one or more output values indicating a number of detected objects within each range-Doppler bin.

Abstract: Systems, methods, and circuitries are provided for calibrating a radar system to compensate for a channel offset. In one example, a method is disclosed for processing radar signals with a radar device. The method includes including receiving respective radar signals from respective virtual receive channels, wherein each virtual receive channel corresponds to a combination of a transmit antenna element and a receive antenna element of an antenna element array. Respective received radar data is generated from the respective radar signals and the radar date is processed to identify one or more stationary objects. Based on the radar data, an estimated radar device motion relative to the one or more stationary objects is determined. A difference between the estimated radar device motion and an expected motion of the radar device is determined and a correction vector is determined based on the difference. The correction vector to is applied to subsequent radar data.

Abstract: According to various embodiments, a radar system is described comprising a radar receiver configured to receive radio signals, wherein each radio signal is associated with a channel of a plurality of channels, a peak detector configured to perform peak detection using the received radio signals, wherein each detected peak corresponds to a detected object and a direction of arrival estimator configured to, for a detected peak, generate a vector having, for each of the channels, an entry specifying a Doppler Fourier transform result for the channel, supply the vector to a machine learning model trained to output, for each of one or more additional channels, an entry specifying a predicted Doppler Fourier transform result corresponding to the additional channel and perform direction-of-arrival estimation using an output from the machine learning model which the machine learning model outputs in response to being supplied with the vector.

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.
