| 摘 要： | 综合考虑卫星的背景特性、材料特性、结构特性和轨道特性,研究了在轨运行卫星存在的自旋稳定、三轴稳定和"翻滚"三种运动状态对卫星光学特性的影响。基于光辐射理论,结合探测器的性能参数,建立了自旋稳定、三轴稳定和"翻滚"三种运动类型卫星的多谱段光学特性计算的数学模型,并进行了实验验证。以海洋一号卫星和实践二号卫星为例,进行了运动状态对卫星多谱段光学特性影响的仿真分析。仿真结果表明,不同运动状态的卫星多谱段辐射特性存在较大的差异。分析结果可为卫星的探测和辨识提供一定的参考价值。 |

| Abstract: | The background characteristics, materials characteristics, structure characteristics and orbit characteristics of the satellite are comprehensively considered to study the influence of motion status of satellite on its multispectral optical characteristics. The motion status of the satellite can be classified into spin-stabilized, three-axis stabilized and “tumbling” status. Based on optical radiation theory, the calculation model of multispectral characteristics of satellites is built for three kinds of motion status combined with the performance parameters of the detector. Taking HY-1 satellite and SJ-2 satellite as examples, the simulation on influence of motion status on multispectral optical characteristics of satellites is made. The results show that satellites with different motion status exhibit remarkable different multispectral characteristics, which provides a certain reference for detection and identification of satellites. |
