Abstract
A radar device includes a transmission module that generates a transmission chirp signal, and reception modules that each receive a reflected wave and a direct wave of the transmission chirp signal, and perform mixing on a received signal, using a reception chirp signal. The radar device includes a signal processing unit that detects a target on the basis of a beat signal resulting from the mixing performed by the reception modules. The signal processing unit detects a level of the beat signal generated from the received direct wave. The signal processing unit determines a failure of the radar device by comparing the detected level with a threshold set on the basis of a beat signal level measurement under an environment that eliminates the reflected wave in advance. The transmitted chirp signal distributed from the transmission module is used as the reception chirp signal.
