摘　　要：介绍了一台双波长双视场米散射激光雷达,采用双接收通道分别用于高低层532 nm及1064 nm的同时探测,每个通道有各自独立的视场,可以兼顾低层大视场角低探测盲区和高层小视场角高探测高度的要求.该雷达系统能够自动连续探测532 nm及1064 nm大气气溶胶消光系数的垂直廓线和连续分布,并通过分析能够获得大气气溶胶的各种光学参数。对比验证实验表明,双波长双视场米散射激光雷达数据可靠,性能稳定。A two-wavelength lidar system with two receivers was developed to measure the aerosol extinction coefficient profiles at 532 nm and 1064 nm in the troposphere. Each received channel with different field of view, can satisfy the needs of low dead zone in short-range and high detected height in long-range. Some typical aerosol profiles and optical parameters are shown and discussed. The reliability and stability of the lidar are approved.
