摘　　要：利用基于空间外差光谱技术的中高层大气OH自由基甚高光谱探测仪,配合太阳跟踪器,对晴空太阳直射光谱进行测量,获得了308nm波段高分辨率的太阳直射光谱。对干涉数据进行去暗电流、去基线、相位校正和傅里叶变换等处理,得到最终的干涉光谱图。利用辐射传输模型模拟理论上到达地面的光谱,将实测结果与理论模拟结果进行比对发现,光谱匹配一致,这为在轨探测高分辨率太阳光谱与目标散射信号提供了实验数据。We use an ultra-spectral resolution spectrometer for mesospheric OH radicals to obtain a high resolution direct solar spectrum in the wavelength of 308 nm based on spatial heterodyne spectroscopy techniques and the sun direction equipment.By removing the dark current and baseline,phase correction and Fourier transform,we get spectra from interferogram data.The results are in good agreement with radiative transfer model simulation.These results provide experimental data for orbital high resolution solar spectra and scattering signal detection.
