ABSTRACT:
This radar device includes: a transmitter to transmit a transmitting signal whose frequency is periodically increased/decreased at a predetermined rate of change; a mixer to generate a beat signal by multiplying a received signal being transmitted by the transmitter and reflected back from an object to be detected and the transmitting signal; a frequency detector to detect a frequency of the beat signal; and a controller to control the rate of change of the frequency of the transmitting signal so that the frequency of the beat signal detected by the frequency detector becomes equal to or larger than a cut-off frequency of a flicker noise caused by the mixer.
