Abstract

According to a first example implementation, the method comprises providing a local oscillator signal in a first radar chip based on a local oscillator signal generated in a further radar chip; supplying the local oscillator signal to a transmission channel of the first radar chip which, based on the local oscillator signal, generates an HF output signal; changing the temperature and/or supply voltage of the first radar chip; measuring phase values based on the local oscillator signal supplied to the transmission channel and of the corresponding HF output signal for different temperature values and/or for different supply voltage values of the first radar chip; and ascertaining calibration data based on the measured phase values for a phase calibration to compensate for changes in the phase of the HF output signal resulting from a change in the temperature and/or in the supply voltage.
