摘　　要：多通道扫描成像辐射计是FY-4卫星的主要载荷之一,可实现对地的多光谱观测。辐射计在轨运行期间承受复杂的外热流环境,为保证高质量的成像品质,必须对其进行有效的热设计。根据地球静止轨道和辐射计构型特点,分析了热设计的特点,并对仪器进行详细的热设计和热分析,计算结果证明了热设计方案的合理性。The multi channel scanning imagery radiometer is one of the main payloads of FY-4 satellite, which can observe multi spectrum from earth. The radiometer will endure complicated heat flux environment in orbit, and effective thermal design for the instrument is required in order to ensure high quality scanning image. Based on characteristics of heat flux in geostationary earth orbit and the unique structure of radiometer, thermal design characteristic was analyzed, and detailed thermal control design was developed with numerical analysis. The numerical results verified the validity of thermal control design.
