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.
