| 摘 要： | 太空目标表面温度受地球下垫面辐射的影响，在对太空目标的计算中通常将下垫面作为均 匀的热辐射平衡体，而受地物类型及气象条件的影响，地球表面的反射率和热辐射值随地理位置和季 节变化，文中介绍了下垫面热流的计算方法，并根据所获得的地表温度数据以及地物类型信息，采用 不同的下垫面处理方式，初步分析了地球下垫面的不均匀性对太空目标表面温度的影响。

| Abstract: | The temperature of space object is influenced by the underlying surface of the earth. In the thermal analysis of the space object, the underlying surface of the earth is regarded as uniform thermal radiation surface. Affected by the landmark and meteorological conditions, the reflectivity and radiation flux intensity changes with the location and the season. The simulation method of the radiant heat flux of the earth was given. Based on the data of the telemetric temperature and different land cover types of the earth, using different simulation method of the radiant heat flux, the influence of the non-uniform underlying surface on the temperature of space object was analyzed. The influence to the light decoys was a little obvious. |
