| 摘 要： | 对空间目标白天探测的关键技术，包括大气透过率分析、天空背景辐射分布、探测能力计算等进行了研究。在此基础上选取K波段光谱在1.23 m口径地基光电望远镜上进行白天观测实验，对关键技术进行验证。实验数据表明，经过优化设计此系统在30俯仰角时白天极限探测10.38等星，较未优化前白天探测能力提高24.9%，为中高轨卫星的全天时观测提供重要依据。

| Abstract: | The key technology of space target detection was studied during daytime, including analysis of atmospheric transmittance, sky background radiation measurement, detection ability calculation. Infrared K band spectrum was applied to the 1.23 m large aperture telescope to verify the key theoreties. Experiment shows that after optimization the limit detection of infrared optoelectronic system is 10.38 magnitude at 30 pitching angle and the detection ability increases 24.9% than before optimization. This research has a positive significance for mid-high orbit satellite detection throughout the day. |
