| 摘 要： | 设计了发射波长为532nm测量大气水汽的拉曼激光雷达系统. 结合系统误差理论分析，验证系统夜间测量水汽的高效性和白天测量水汽的可行性. 通过对比不同发射波长的拉曼激光雷达系统的回波信号与信噪比，得出最优系统参数能够实现白天0~4km、夜间0~9km的探测，该系统探测性能优于266nm或355nm的测量系统，特别是夜间探测大气水汽更为高效. 为实现单波长测量大气参数（温度、气溶胶和水汽）提供了一个可行性设计.

| Abstract: | A Raman lidar system with emission wavelength of 532nm was designed to measurement of atmospheric water vapor. Combined with error theory analysis, the feasibility during the daytime and the accuracy during the night for the Raman lidar system on water vapor measurement with 532nm were verified. Besides, SNRs with different parameters were calculated. The results show that with proper parameters design, the detect ranges could be 0~4km during the daytime and 0~9km at night respectively. And its performance is much better than that of system with 266nm or 355nm, which brought a feasible design for atmosphere parameter measurements, such as temperature, aerosol and water vapor. |
