摘要
开发了提取FY-3A紫外臭氧垂直探测仪遥感数据并进行处理的星上数据预处理软件。预处理包括引入仪器光谱响应度地面辐射定标数据,进行角度响应修正、非线性修正、换档比及漫反板衰减修正等。介绍了软件修正功能的原理,结合紫外臭氧垂直探测仪的在轨测量模式建立了相应数据修正算法和模型,并将修正算法和模型转化为功能丰富的星上数据预处理软件。使用该软件得到了在轨测试的太阳紫外光谱预处理数据,并以此为例给出了验证结果。分析比对表明,FY-3A星紫外臭氧垂直探测仪的全部软件功能均已得到实现,所测太阳紫外光谱与国外仪器数据比对其一致性达到±5%以内,验证了数据预处理软件的正确性。
A software for extracting and pre-processing in-orbit data from a FY-3A Solar Backscatter Ultraviolet Spectrometer（SBUS） is developed.The software is mainly based on ground spectral responsivity calibration factors and some correction functions including goniometric response,nonlinearity,interrange ratios and diffuser attenuation.The principle of modified function of the software is introduced and the corresponding modified algorithm and module are established by the combination of SBUS in-orbit measuring modes and the correction principle.The modified algorithm and module are converted into a in-orbit data pre-processing software with abundant functions.The software is used to process the in-orbit spectrum measured by the solar ultraviolet spectrometer,it is then taken as an example to prove obained results.Verified experiments show that all the software functions of satellite borne SBUS have been implemented,and the similarity between the data from the solar ultraviolet spectrum and the data from SBUV/2 is within ±5%,which validates that the pre-processing software is practical.
