摘要

摘要: 从白天天空背景、恒星光谱特性、星敏感器的构造特点3方面分析白天大气层内小视场轻型星敏感器对恒星探测的可行性。在此基础上，采用光谱滤波、合理选择系统参数等方法，研制了小视场轻型星敏感器，并在高海拔地区进行了白天地面观星实验，理论分析和实验结果表明：小视场轻型星敏感器能够实现白天恒星的探测。在3 km海拔高度、大气能见度10 km、视场21.5、太阳规避角30以外、天空晴朗无云的环境下，可探测星等极限值达到3.8等。

Abstract: The feasibility of the stellar detection within the atmosphere in daytime by using light star sensor with small field was analyzed from the sky background, the spectral properties of star, and the structure characteristic of star sensor. Using the method of spectral filtering and reasonable choice of system parameters, a light star sensor was developed. Moreover, star detect experiment in daytime was carried out in high altitude area. With the observing altitude of 3 km, the atmosphere visibility of 10 km and the field of view of 21.5, the maximum detectable stellar magnitude limit was 3.8 when the avoiding angle of the sun was out of 30. The theory analysis and experiment result both indicate that light star sensor with small field can detect star in daytime.
