Millimeter wave radar device for sensing obstacles on railway

A millimeter wave radar device for sensing an obstacle on a railway is applied to a railway and an obstacle, and comprises a user interface and a millimeter wave radar. The user interface is configured to control the millimeter wave radar; the millimeter wave radar is configured to send a radar wave to a preset range on the railway; the millimeter wave radar is configured to receive a reflected radar wave reflected from the preset range on the railway based on the radar wave; the user interface is configured to determine whether the obstacle is within the preset range on the railway based on the reflected radar wave; if the user interface determines that the obstacle is within the preset range on the railway, the user interface is configured to provide a warning. 一种感测铁路上障碍物的毫米波雷达装置，应用于一铁路及一障碍物，该感测铁路上障碍物的毫米波雷达装置包含一使用者界面及一毫米波雷达。该使用者界面被配置为控制该毫米波雷达；该毫米波雷达被配置为发送一雷达波至该铁路上的一预设范围；该毫米波雷达被配置为接收基于该雷达波的从该铁路上的该预设范围所反射的一反射雷达波；该使用者界面被配置为基于该反射雷达波判断该障碍物是否在该铁路上的该预设范围内；如果该使用者界面判断该障碍物在该铁路上的该预设范围内，则该使用者界面被配置为提供一警告。
