摘　　要：激光雷达作为一种新型的大气观测工具,可以通过直接探测激光与大气相互作用的光辐射信号来定量地反演大气水平能见度,从而成为测量大气水平能见度的主要手段.正在研制的一台基于532nm波长的车载式米散射激光雷达,用于大气能见度的测量;简单介绍了正在研制的激光雷达的技术参数,给出了测量数据的处理方法;利用雷达的技术参数进行了模拟计算,显示了该激光雷达探测大气水平能见度的可靠性,计算误差显示在大气能见度为10km时该激光雷达的测量误差小于16%.As a new tool to detect atmosphere, lidar can derive the value of visibility by directly collecting the scattered laser from the atmosphere. It makes lidar become a main instrument for measuring visibility. A 532nm-wavelength Mie lidar is being developed to measure atmosphere visibility. Specification of the lidar and the measuring method and algorithm for measurement are introduced. The results show that Mie lidar has high reliability through simulating with lidar parameter. The error of calculating for visibility is less than 16%.
