摘　　要：作为一种激光探测大气气溶胶特征的新技术 ,采用分子滤波技术的高光谱分辨率激光雷达在国际上得到了发展。给出了对这种YAG激光雷达系统的理论分析并建立了实验装置 ,其接收望远镜孔径为 30 0mm ,YAG激光脉冲能量为 15 0mJ。通过数值模拟与初步测量估计了激光雷达性能 ,测量了大气回向散射信号 ,测量结果表明实验结果与理论分析一致。A new technique for measuring atmospheric aerosol characteristics using YAG lidar with iodine cell filter has been developed. The theoretical analysis of the YAG lidar system was given and experimental YAG lidar system was built with 300 mm aperture receiving telescope and 150 mJ YAG laser pulse energy, assessment of the lidar system performance was given through numerical simulations and primary experiments. Backscattering signals from atmosphere were measured. The data measured show that theoretical analysis and experiment results are coincident.
