A radar system includes a local oscillator for generating a local oscillator signal, transmission channels, and a reception channel. The transmission channels are designed to generate and output RF radar signals based on the local oscillator signal The transmission channels have phase shifters for setting the phase of the RF radar signals. The reception channel is designed to receive an RF signal and to convert it into a baseband signal by using the local oscillator signal supplied thereto. A method includes operating the local oscillator in a CW mode, setting a specific combination of phase shifts for the phase shifters of the transmission channels, altering the phase of the local oscillator signal supplied to the reception channel or of the phase shifts of the phase shifters by a phase offset, and ascertaining that phase offset for which the baseband signal at least approximately assumes a maximum.
