Illustratively, the first lobe 111 may be a main lobe of the radiation pattern of the radar antenna 110 and the second lobe 112 may be a side lobe of the radiation pattern of the radar antenna 110. Since the first lobe 111 of the radiation pattern of the radar antenna 110 faces the first face area, and the second lobe 112 faces the reflecting device 120, it is possible to achieve higher gain coverage of the first face area, obtain richer data information of the first face area, and meanwhile, ensure effective data information acquisition of the second face area.
