1. An automotive radar system, comprising:
a radar receiver configured to generate radar reception data from radio signals received by a plurality of radar receive antennas;
a radar signal processor configured to determine an estimate of an angular position of at least one object by processing the radar reception data;
a communication interface configured to receive information about a reference angular position of the at least one object;
a determiner configured to determine a compensation value for the radar reception data based on the estimate of the angular position of the at least one object and the reference angular position of the at least one object, wherein the radar signal processor is configured to correct the radar reception data and/or further radar reception data for detection of a further object based on the compensation value; and
an output interface configured to provide information about a presence of the further object to a vehicle controller,
wherein the compensation value comprises a plurality of compensation values, and wherein the determiner is configured to sequentially compute the plurality of compensation values to first compensate errors on an individual component level and to subsequently compensate errors on a multi-component level.
