摘　　要：为满足国家对大气参数测量的需求,成功研制了新型车载式大气探测激光雷达系统。该激光雷达主要是通过接收激光与大气中气溶胶粒子和水汽以及氮气分子间的米和拉曼散射信号,结合相应的激光雷达方程,反演出大气水平能见度、垂直气溶胶消光系数和水汽混合比。最终的实际测量结果与对比实验显示,该激光雷达可以对对流层的大气气溶胶进行昼夜连续观测,对夜晚8km高度范围内以及凌晨和傍晚时分边界层内的水汽进行测量。相应大气水平能见度的测量误差小于20%,而垂直大气气溶胶和水汽的测量误差最大不超过30%。For national need to measure the atmosphere parameters, the new mobile Raman-Mie scattering lidar system has been developed. Through collecting the Raman and Mie backscattering laser, this lidar can measure the horizontal visibility, vertical aerosol extinction and water vapor mixing ratio. The results of comparative experiment show that this lidar system can take measurements of tropospheric aerosol in day and night continuously, water vapor over 8 km height at dusk and before dawn in boundary layer. The corresponding error of measurements for horizontal visibility is less than 20%, and it is not greater than 30% for vertical aerosol and water vapor.
