Provided is a radar apparatus, which is mounted in a movable body, for detecting an obstacle in the vicinity of the movable body. The radar apparatus comprises a transmitting section (201), a receiving section (202), a velocity acquisition section (204), a reference signal acquisition section (205), and a signal processing section (203). The transmitting section (201) transmits a radar beam into which a transmission signal is modulated by a predetermined frequency. The receiving section (202) receives a reception signal into which the radar beam, which is transmitted from the transmitting section (201) and then is reflected by the obstacle, is demodulated by the predetermined frequency. The velocity acquisition section (204) obtains a velocity of the movable body. The reference signal acquisition section (205) obtains the reception signal as a reference signal in the case where the velocity obtained by the velocity acquisition section (204) is equal to or greater than a predetermined value. The signal processing section (203) detects the obstacle by using the reception signal and the reference signal.
