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: 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.

Abstract: According to various embodiments, a radar system is described including a direction of arrival pre-processor configured to, for a detected peak, obtain a Doppler Fourier transform result vector, generate a spatial covariance matrix for the Doppler Fourier transform result vector, and generate an additional spatial covariance matrix by inputting the spatial covariance matrix to a machine learning model trained to predict, from an input spatial covariance matrix, an output spatial covariance matrix such that the output spatial covariance matrix corresponds to a different chirp center frequency than the input covariance spatial covariance matrix and including a direction of arrival estimator configured to perform direction-of-arrival estimation using the additional spatial covariance matrix.

Abstract: According to one embodiment, a radar receiving system is provided comprising a first receiving circuit, a second receiving circuit, a spectral analyzer, an object detector, and a phase compensation circuit. The spectral analyzer is configured to generate, from a first plurality of reception signals, a first set of Fourier transformation output values and, from a second plurality of reception signals, a second set of Fourier transformation output values. The object detector is configured to determine a range/Doppler bin of a plurality of range/Doppler bins as an estimate of a range and speed of an object. The phase compensation circuit is configured to determine a phase offset between the Fourier transformation output values of the first set and second set of Fourier transformation output values and to compensate the phases of at least a part of the second set of Fourier transformation output values by the determined phase offset.

Abstract: It is suggested to process radar signals including: (i) receiving reception signals via at least one antenna of a first receiving circuit; (ii) determining an interim result by processing the reception signals via a frequency transformation; (iii) determining an error compensation vector based on the interim result and an expected characteristic; and (iv) applying the error compensation vector on other reception signals that have been processed via the frequency transformation.
