目前对于地球同步轨道(GEO)空间目标的探测和识别主要依靠反射太阳光的光度变化进行分析识别并判断.基于空间目标表面漫反射性质的可见光反射特性计算模型分析,研究了不同形状反射体可见光反射特性,并提出一种采用不同形状反射体控制改变空间目标可见光反射特性的方法.以GEO卫星为例,采用基于蒙特卡罗的非序列光线追迹方法,仿真分析椎体、球体和圆柱体作为反射控制体对卫星光变特性的影响.结果表明该方法可改变卫星原有可见光反射光变曲线,降低卫星被探测识别概率,提高空间目标隐蔽性.
At present, the detection and recognition of GEO space targets mainly rely on the analysis and identification of the photometric changes of reflected sunlight.According to the calculation model of visible light reflection properties of diffuse reflection of spatial target surface, And proposes a method of controlling the visible light reflection of space objects by using different shape reflectors.With GEO satellite as an example, a non-sequential ray tracing method based on Monte Carlo is used to simulate the vertebral body, sphere and cylinder As a reflection control body on the optical characteristics of the satellite.The results show that this method can change the original curve of the visible light reflection of the satellite to reduce the probability of satellite detection and detection to improve the concealment of the spatial target.
