A radar device includes: an aperture surface, which includes element antennas and phase shifters; an antenna phase control unit configured to set phases to the phase shifters and calculate phase amounts based on a beam orientation direction and on a rotation angle of the aperture surface; a rotation mechanism configured to rotate the aperture surface; an antenna driving control unit configured to set a rotation angle to the rotation mechanism; a resolver configured to detect the rotation angle of the aperture surface; an exciter configured to generate transmission signals; a radar receiver configured to process reception signals; a signal processing unit configured to detect a target with the use of the radar receiver, set at least one of the rotation angle of the aperture surface or the beam orientation direction in the antenna driving control unit and the antenna phase control unit, and calculate the level of competing cluttering with the use of an antenna pattern, to thereby determine propriety of the rotation angle; and a pattern calculating unit configured to calculate the antenna pattern from the rotation angle of the aperture surface and from the beam orientation direction. |
