Abstract
An object detection apparatus includes a first acquisition unit that acquires, as a first direct wave group, reflected versions of first probing waves transmitted from and received at a first position, and acquires, as a first indirect wave group reflected versions of the first probing waves received at a second position, a second acquisition unit that acquires, as a second indirect wave group, reflected versions of second probing waves transmitted from the second position and received at the first position, and acquires, as a second direct wave group, reflected versions of the second probing wave received at the second position, and a determination unit that determines whether the object is a real object or a ghost in accordance with the receptions times of the first and second direct wave groups and the first and second indirect wave groups.
