Abstract
An object detection apparatus is mounted to a vehicle and detects an object by a reflected wave of a probe wave. The object detection apparatus calculates a relative velocity of the object to the vehicle, estimates an azimuth of the object relative to the vehicle, and corrects the estimated azimuth. The object detection apparatus generates a velocity-azimuth curve that indicates a relationship between the relative velocity of the object and the azimuth of the object that is calculated based on a theoretical mounting angle of the object detection apparatus, supplies a weight to an azimuth error that is an error between the velocity-azimuth curve and the estimated azimuth, based on the estimated azimuth, and calculates a correction value of the estimated azimuth by calculating, as an actual mounting angle deviation of the object detection apparatus, a weighted average value of the azimuth error to which the weight is supplied.
