地球静止轨道凝视型相机热分析与热设计

空间光学遥感器在轨运行过程中要承受太阳辐射和空间冷热沉、黑热沉等恶劣温度环境的影响。为确保相机在轨正常运行并拥有较高的成像品质,需要对相机进行精确的热控设计。根据地球静止轨道太阳辐射外热流特点,详细分析了静止轨道凝视相机热设计的重点和难点,并针对热设计中可能遇到的问题提出相应解决方案。

Preliminary Research on the Thermal Design Methods of the Geosynchronous Orbit Stating Camera

The space optical remote sensor is influenced by the solar radiation,albedo,earth emitted infrared and other heat sources as flying in the heat dreariness astrospace.Therefore,the precise thermal design become the key point to ensure the camera working normally with high imaging qualities.The emphases and difficulties of the geosynchronous orbit staring camera thermal design are analyzed based on the orbital heating analysis of sun radiation.The solutions to possible problems in the thermal design is provided.
