Abstract
An axial misalignment estimation apparatus calculates a first estimated speed ratio that is an estimated speed ratio calculated using an orientation angle that is corrected based on an axial misalignment angle estimated in measurement cycles up to a previous measurement cycle, and calculates at least one second estimated speed ratio that is the first estimated speed ratio presuming aliasing is present at the orientation angle. The axial misalignment estimation apparatus determines, for each stationary reflection point, whether aliasing is present at the orientation angle of the stationary reflection point based on the first estimated speed ratio and the at least one second estimated speed ratio, and corrects the orientation angle of the stationary reflection point in which aliasing is determined to be present, and estimates the axial misalignment angle based on the corrected orientation angle for the stationary reflection point of which the orientation angle is corrected.
