Solar-blind ultraviolet Raman lidar can realize the daytime detection of atmospheric water vapor, as the transmitting wavelength of 266.0 nm and its excited vibrational Raman spectra of N₂, O₂ and H₂O are within the solar-blind region. However, the spectra of the O₃, NO₂, SO₂ absorptions and fluorescence are within the solar-blind region as well, and Raman channel of H₂O still has a small amount of residual solar background noise, which will influence the detection accuracy and detection capability of the solar-blind ultraviolet Raman lidar. Moreover, although a high efficiency polychromator is required to extract the vibrational Raman spectra of N₂, O₂ and H₂O, the suppression of aerosol Mie scattering and molecular Rayleigh scattering, and optical cross-talks are still required to discuss carefully in detail. Simulation results show that the retrieval accuracy of water vapor mixing ratio using the solar-blind Raman lidar are mainly influenced by the O₃ absorption and the optical cross-talk of aerosol Mie scattering and molecular Rayleigh scattering. The rejection ratio with more than 5 orders of magnitude to elastic scattering signal is required in the design of polychromator to avoid the optical cross-talk between each extracted spectrum. The influences of NO₂, SO₂ absorptions, solar background noise and fluorescence on the retrieval of water vapor mixing ratio can be neglected. The theoretical analysis of the solar-blind ultraviolet Raman lidar on the retrieval of water vapor mixing ratio can further enhance the performance of the system detection accuracy and detection capability.

日盲紫外拉曼激光雷达可以实现白天对大气水汽的探测，因为其透射波长为266.0 nm，其激发振动拉曼光谱N ₂，O ₂和H ₂ O处于日盲区域内。但是，O ₃，NO ₂，SO _2的吸收和荧光光谱也位于太阳盲区之内，H ₂ O的拉曼通道仍然具有少量的残留太阳本底噪声，这将影响检测。太阳盲紫外拉曼激光雷达的精度和检测能力。此外，尽管需要高效的多色仪来提取N的振动拉曼光谱仍然需要仔细地讨论图₂，O ₂和H ₂ O，抑制气溶胶米氏散射和分子瑞利散射以及光学串扰。仿真结果表明，太阳盲拉曼激光雷达对水汽混合比的反演精度主要受O ₃吸收以及气溶胶米氏散射和分子瑞利散射的光学串扰的影响。在多色仪的设计中，对弹性散射信号的抑制比必须大于5个数量级，以避免每个提取光谱之间的光学串扰。NO ₂，SO _2的影响吸收率，太阳本底噪声和荧光对水蒸气混合比的恢复率可以忽略不计。对太阳盲紫外拉曼激光雷达对水汽混合比的反演进行理论分析，可以进一步提高系统的检测精度和检测能力。
