摘　　要：空间碎片主动清除需要充分掌握碎片的旋转运动特性,而对碎片进行光度变化分析是提取目标旋转特性的有效手段。文章基于统计获得的双向反射分布模型,建立了典型空间碎片光度变化分析模型,模拟分析了不同旋转态下碎片的光度信息变化。基于光变曲线分析,确定了光度变化峰谷差值与旋转轴向相位角在不同旋转轴指向变化条件下的变化规律,并通过光变分析近场模拟试验进行了验证。另外,在光度差值分析基础上,提出了缩小搜寻旋转轴指向取值区间的方案,为简化遍历式旋转轴向提取流程提供了支持。Active debris removal technology requires full grasp of the debris rotational motion characteristics,and light curve analysis of debris is an effective way to extract the rotation characteristics of the target.Based on the typical Bidirectional Reflectance Distribution Function(BRDF),a model was established in the paper for analyzing the light curve of typical space debris,and the photometric information of debris was simulated in different rotation states.The variation rule of the light curve peak-to-valley difference with the continuous change of the rotation axis phase angle was determined based on light curves analysis under different rotation axes conditions,and then verified by optical variation analysis experiments.Based on analysis under different conditions,the scheme is determined to effectively reduce the value range of the rotation axis directions,which is helpful for simplifying the traversal rotation axial extraction process.
