Abstract: Systems, methods and circuitries are disclosed for compressing radar data. In one example, a radar sender unit includes adaptive compression circuitry configured to determine tuning data, wherein the tuning data is based on one or more operating conditions; compress radar data based on the tuning data; and transmit the compressed radar data to a radar control unit for further processing.

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: 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: An automotive radar arrangement includes a radar receiver configured to generate radar reception data from radio signals received by a plurality of radar receive antennas. A radar signal processor is configured to determine an estimate of an angular position of at least one object by processing the radar reception data. A communication interface is configured to receive information about a reference angular position of the at least one object. A determiner is configured to determine a compensation for the radar reception data based on the estimate of the angular position and the reference angular position of the at least one object. The radar signal processor is configured to correct the radar reception data and/or further radar reception data for the detection of a further object based on the compensation. An output interface is configured to provide information about the presence of the further object to a vehicle controller.
