ABSTRACT:
A target determination apparatus includes a reception unit, a judgment unit, and a determination unit. The reception unit receives a reflection wave from a target. The judgment unit judges as to whether or not a fluctuation state of reception intensity of the reflection wave with time corresponds to a distinction state occurring when the target is a predetermined type, on the basis of information concerning the reception intensity of the reflection wave. The determination unit determines type of the target on the basis of judgment result of the judgment unit.
