Abstract
A radar apparatus includes a radar transmitter that transmits a radar signal in a predetermined transmission cycle and a radar receiver that receives a reflection wave signal being a reflection of the radar signal on a target. The radar transmitter includes a phase rotation controller that randomly varies a pattern of a phase rotation every period corresponding to a plurality of transmission cycles, the pattern being to be applied to the radar signal within a period, and a transmission phase rotator that assigns a first phase rotation to the radar signal in accordance with the pattern. The radar receiver includes a reception phase rotator that assigns a second phase rotation in a direction opposite to a direction of the first phase rotation to the reflection wave signal in accordance with the pattern.
