An information acquisition unit (S110) repeatedly acquires observation point information including an observation orientation from a radar device. An axis offset acquisition unit (S120) acquires an axis offset amount of an actual mounting direction indicating an actual orientation of a radar device with respect to a reference mounting direction of the radar device. An aliasing calculation unit (S190) calculates an aliasing orientation relating to the observation orientation included in the observation point information. The instantaneous determination unit (S210-S220) determines, as an actual orientation, one of the observed orientation and the aliasing orientation closer to a mounting reference direction estimated from the amount of axial displacement and the actual mounting direction.
信息获取部(S110)从雷达装置反复获取包含观测方位的观测点信息。轴偏移获取部(S120)获取表示雷达装置的实际的朝向的搭载实际方向相对于雷达装置的搭载基准方向的轴偏移量。混叠计算部(S190)计算关于观测点信息所包含的观测方位的混叠方位。瞬时判定部(S210~S220)将观测方位和混叠方位中的、更接近根据轴偏移量和搭载实际方向推断的搭载基准方向的一方判定为实际的方位。
