Abstract: Provided is an obstacle determination apparatus including: a first determiner determining a difference in a propagation distance or a propagation time between a first round-trip path of a detection wave and a second round-trip path of a detection wave; and a second determiner determining whether the object is an obstacle based on a determination result of the first determiner.
