Each of the positional parameters of a corresponding one of the reflection points in the first direction represents a position of the corresponding one of the reflection points in the first direction. A measuring unit performs a two-dimensional trilateration localization for each of the groups based on at least one reflection point included in a corresponding one of the groups to thereby calculate a location of the at least one reflection point included in each of the groups in a second plane. The second plane is defined by the second direction and a group center direction of the corresponding one of the groups.
