利用太阳光谱辐射计进行了可见到近红外波段整层大气连续光谱透过率的测量研究．在对太阳辐射计可靠定标的条件下，通过测量太阳直射光谱，运用Langley方法推算到达大气层顶的太阳辐射，最终获得了该波段范围内的连续大气光谱透过率及特殊波长上的透过率的实际变化情况．通过分析晴天无云大气条件下不同时间、不同气溶胶含量、不同季节、不同气溶胶模式下的大气透过率特征，初步获得了其变化规律，为大气层外目标探测提供了一些基础．

Continuous spectra transmittance is measured and studied from visible to near infrared bandsusing sun photometer. The atmospheric transmittance is obtained with the solar spectra measured by the accurate calibration sun photometer by Langley method to calculate the irradiance arrive at the top of the atmosphere. From the analyses of different time,aerosol contents,seasons and models,the characters of the atmospheric transmittance are achieved in the sunny,cloud free atmospheric condition. The results can provide the base for target detection out of the atmosphere.
