Abstract
A radar system and a method for a radar system are described. In accordance with one exemplary embodiment, the method includes generating a local oscillator signal in a first radar chip, generating a frequency-divided signal from the local oscillator signal by means of a frequency divider arranged in the first radar chip, transmitting the frequency-divided signal to a second radar chip, and transmitting the local oscillator signal to the second radar chip. The local oscillator signal received in the second radar chip is fed to an output channel of the second radar chip, which generates an output signal on the basis thereof. The method further includes generating—on the basis of the output signal of the output channel and the frequency-divided signal received by the second radar chip—a signal indicating a phase angle of the output signal relative to the received frequency-divided signal.
