通过在紫外(UV)大气成分探测仪中设置偏振测量通道，并采用基于Stokes向量方法对空间大气紫外光谱辐亮度探测输入值进行了偏振度修正。采用解析函数法建立了修正误差较大波段处的偏振度数学模型，将240~380 nm工作波段范围的偏振度修正误差最大值由6.6%减小至1.6%。最大限度降低了由于大气散射偏振对探测大气入射光强的影响，提高了紫外大气测量精度，为航天遥感仪器大气紫外测量提供了理论和实验基础。

By setting polarization measurements channel in ultraviolet (UV) atmospheric constituents probe, the detection input value of UV atmospheric spectral radiance polarization is corrected based on the Stokes vector approach. The method of analytical functions is used to establish a mathematical model for the degree of polarization when correction error is largest, and the polarization degree maximum error correction is decreased from 6.6% to 1.6% in the working wavelength from 240 nm to 380 nm. The maximum influence on the atmosphere measurements is strongly reduced due to atmospheric scattering of incident light polarization detection, and the accuracy of UV atmospheric measurements is improved, which provides theoretical and experimental basis for aerospace remote sensing instruments to measure UV atmospheric.
