摘　　要：星载激光雷达是高精度测量全球温室气体和气溶胶垂直廓线的重要手段,大气环境监测卫星大气探测激光雷达(ACDL)在国际首次采用激光积分路径差分吸收技术测量全球CO_(2)柱浓度,采用532 nm高光谱探测技术测量气溶胶和云的廓线。星载激光雷达载荷研制期间,同步研制一套主要功能一致的机载大气探测激光雷达校飞样机,并开展机载飞行试验,获取了大量飞行试验及其对比数据,提供了机载平台真实的数据源,对于优化ACDL激光雷达系统参数和研究星载数据反演算法至关重要。最后在机载飞行平台下,验证了优于1×10^(-6)的CO_(2)柱浓度测量精度和优于15%的气溶胶测量精度。未来利用该机载样机可以进一步开展星地对比验证。Spaceborne lidar serves as a critical tool for high-precision measurement of the vertical profiles of global greenhouse gases and aerosols.The aerosol and carbon dioxide(CO_(2))detection lidar(ACDL)is the first system in the world to use the laser integral path differential absorption technology to measure the global CO_(2) column concentration and the high spectral resolution detection technology at 532 nm to measure the profiles of aerosols and clouds.During the development of the spaceborne lidar payload,a set of airborne atmospheric detection lidar prototypes with the same main functions are developed simultaneously,and the related airborne flight experiments are carried out.A large number of flight tests and comparative data are obtained,providing the real data source of the airborne platform,which is crucial for optimizing the parameters of the spaceborne ACDL lidar system and the inversion algorithm of the spaceborne lidar.Finally,under the airborne flight platform,the CO_(2) column concentration measurement accuracy of better than 1×10^(-6) and the aerosol profile measurement accuracy of better than 15%are verified.In the future,the airborne prototypes can be used to further verify the spaceborne lidar in orbit.
