| 摘 要： | 设计并完成了夜气辉背景下的天基碎片观测试验,获取了综合谱段的观测数据。基于观测数据进行夜气辉的辐射特性及其对天基碎片探测的影响分析。结果表明,夜气辉辐射随纬度和高度呈现一定的分布特点,这些特点均符合夜气辉的理论分布规律。在约90 km处辐射最强,亮度可达到单位积分时间每平方角秒近15星等,这对恒星及碎片提取概率影响较大,其中,13等星的提取概率仅为40.5%。

| Abstract: | The space-based debris observation experiment under the night airglow background is designed and completed, and the observation data in the comprehensive spectrum is obtained. The radiation characteristics of the night airglow and its effects on the space-based debris detection are analyzed based on the observation data. The results show that the distribution characteristics of the night airglow radiation with latitude and altitude are consistent with the theoretical distribution law of the night airglow. The radiation is the strongest at about 90 km, and the brightness can reach nearly 15 star magnitude per square arc second per unit integral time, which has a great impact on the probability of the star and debris extraction, among them, the probability of the 13 magnitude stars extraction is only 40.5%. |
