PROBLEM TO BE SOLVED: To provide a radar axial deviation determination device capable of stably determining the presence/absence of the axial deviation, not being affected by a difference among objects, without using a road surface reflection.SOLUTION: An object search part 114 searches for a one-time reflection component which is composed of a distance and an intensity obtained by receiving a reflection wave reflected on the object one time from distances to the object and intensities of reflection waves calculated when a reception part 13 receives the reflection wave of an electromagnetic wave emitted by a transmission part 12. A multiple reflection component search part 115 searches for a multiple refection component which is composed of a distance and an intensity obtained by receiving a reflection wave reflected on the object multiple times by using the distance of the one-time reflection component detected by the object search part 114 from the distances to the object and the intensities of the reflection waves calculated when the reception part 13 receives the reflection wave of the electromagnetic wave emitted by the transmission part 12. An axial deviation determination part 116 determines an axial deviation on the basis of an intensity ratio function between the one-time reflection component and the multiple reflection component.SELECTED DRAWING: Figure 1 |
