摘要: 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.Abstract: For geosynchronous (GEO) orbit space object's detection and recognition is mainly dependent on analysis, identification and judgment of reflected sunlight photometric curve. Based on analysis of visible light reflection characteristics calculation model of space target surface diffuse reflection properties, a study on different shape reflector light reflection characteristics was carried out. Moreover, a different shape reflector method was proposed to control space target light reflection characteristics. Taking an example of a GEO satellite, simulate and analyze the effects of cone, sphere and cylinder as reflection control body on satellite reflection characteristics by using Monte Carlo non-sequential light tracing method. The results show that the method can change the satellite original visible light reflection curve, reduce the probability of being detected and recognized, and improve the invisibility of space object.
