Abstract
In some implementations, a radar device comprises: a clock input configured to receive a clock signal, a local oscillator configured to generate a first RF local oscillator signal based on the clock signal, and also an RF input configured to receive a second RF local oscillator signal. The radar device further comprises a phase shifter configured to shift the phase of the first RF local oscillator signal or of the second RF local oscillator signal by a settable phase value. A monitor circuit is configured to combine the first RF local oscillator signal and the second RF local oscillator signal and to generate a sequence of signal values based on the combined signal. A computing unit is configured to determine the relative phase of the second RF local oscillator signal in relation to the first RF local oscillator signal based on the sequence of signal values.
