The present invention relates to a method for calibration of a radar system (14) of a vehicle (10) for monitoring an environment of the vehicle (10). During a movement of the vehicle (10) with the radar system (14) at least one radar signal (22) is transmitted into a monitoring area (18). With the radar system (14) at least one echo signal (26) of at least one radar signal (22) is received, which is reflected from at least one target (24). At least one phase-based target angle (ΦS) is determined from at least one phase difference of the at least one received echo signal (26), which is received with different antennas of the radar system (14), wherein the phase-based target angle (ΦS) characterizes the direction of the at least one detected target (24) with respect to a radar reference system (28S) of the radar system (14).

At least one angle correction value (ΔΦ) is determined from a difference of at least one phase-based target angle (ΦS) and at least one Doppler-based target angle (ΦH). The at least one angle correction value (ΔΦ) is stored with at least one of the corresponding target angles (ΦS) in a correction lookup table for the purpose of correcting phase-based target angles (ΦS) at least from subsequent measurements with the radar system (14) to corrected target angles (Φcorr).
