Abstract
The present disclosure relates to a radar device, including a transmitter circuit configured to generate an RF oscillator signal and to transmit an RF fault detection signal based on the RF oscillator signal, a receiver circuit configured to receive an RF reception signal based on the RF fault detection signal and to mix the RF reception signal with the RF oscillator signal in order to obtain a down-converted reception signal, and a fault detection circuit configured to detect a hardware fault of the radar device based on a phase of the down-converted reception signal.
