海洋光学紫外遥感需要通过对紫外探测系统进行精确的辐射定标和系统性能指标测定来实现。本文采用积分球光谱辐射定标法，利用氙灯光源，标定自行研制的一套紫外辐射面阵探测系统。得到待测系统的输出响应与积分球输出光谱辐亮度呈极好的线性关系，线性相关性达99.99%。同时发现氙灯光源存在起伏涨落特性，本文首次提出了氙灯修正模型，建立了基于实测结果、待测系统和氙灯光源三者标准差关系的简易模型，可以修复由于氙灯输出有起伏带来测量失准48%的负面影响，得到待测系统的实际噪声和信噪比。通过文中的理论分析和模型的建立与验证，为氙灯积分球紫外辐射定标和信噪比等参数测定提供理论和数据支持。

In order to achieve ocean optics ultraviolet remote sensing, it is needed to make an accurate radiometric calibration and system performance measurement for the UV imaging detection system. The method of integrating sphere spectral radiometric calibration, with xenon lamp as the light source, is used to calibrate the ultraviolet imaging detection system, which is designed and developed by ourselves. It’s verified that the output response of the UV detection system to the output spectral radiance from integrating sphere is an excellent linear relationship under the same integration time by taking the average of multiple samples, whose linear correlation reaches 99.99%. We have found the xenon lamp with a property of fluctuation, whose output spectral radiometric has ups and downs. In this paper, we firstly propose a model for xenon lamp, which is based on the relationship of three kinds of standard deviations of experimental results, UV imaging system and xenon lamp. This model can be used to correct the 48% inaccuracy of negative effect by the fluctuation of xenon lamp, and finally fix and get the real noise and SNR of whole system. Through the theoretical analysis, the establishment and verification of fixed model, it could provide theoretical and data support for xenon lamp integrating sphere UV calibration and parameters measurement like SNR.
