A computer implemented method for calibrating a radar sensor comprises the following steps carried out by computer hardware components: acquiring a plurality of radar detection data sets; for each of the plurality of radar detection data sets, determining an angle of arrival of the radar detection data under the assumption that the respective radar detection data set is related to a stationary object; for each of the plurality of radar detection data sets, determining a respective set of candidate entries of a calibration matrix of the radar sensor based on the respective angles of arrival determined for the respective plurality of radar detection data sets; and determining a set of entries of the calibration matrix of the radar based on the plurality of sets of candidate entries.

Methods and systems for calibrating a radar sensor

An illustrative example embodiment of a detector device, which may be useful on an automated vehicle, includes an array of detectors arranged in one dimension. The array includes a plurality of first detectors and a plurality of second detectors. The first detectors respectively have one of the second detectors between the first detector and an adjacent one of the first detectors. The first detectors respectively are spaced from the one of the second detectors by a first distance. The one of the second detectors are respectively spaced from the adjacent one of the first detectors by a second distance that is larger than the first distance. The first detectors are spaced from each other by a third distance that is a sum of the first and second distance. The second detectors are also spaced from each other by the third distance.
