【摘要】 当前高面质比空间碎片对在轨航天器及载人航天活动的威胁与日俱增,针对高面质比空间碎片轨道漂移造成编目识别困难,提出利用碎片表面材料的光谱特性识别高面质比空间碎片。该方法对空间碎片图像预处理,修正其大气消光和望远镜光学系统的影响,抽取碎片光谱曲线,将实测光谱曲线与样本材料进行比对,分析两者光谱曲线特性,识别高面质比空间碎片表面材料。低色散光谱观测数据表明:该方法对于铝、白漆单一表面材料为主的卫星和火箭箭体等高面质比空间碎片具有较高的准确性,其相关系数大于0.9。更多还原

【Abstract】 High area-to-mass ratio space debris currently poses an increasing hazard to active satellites in orbit and manned space activities. Due to the difficulties in recognition and cataloging of high area-to-mass space debris, a method based on spectroscopic observations is proposed. This method corrects atmospheric extinction and the impact of telescope optical system on the basis of image preprocessing, extracts space debris reflectance spectroscopy, then compares with the spectral curves of sample materials and recognizes surface materials of high area-to-mass ratio space debris. Results of spectroscopic observations show that it will be fairly accurate if high area-to-mass ratio space debris is composed of a single material, such as aluminum and white paint, and the correlation coefficients of aluminum and white paint are approximately 0.9.更多还原
