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。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.
