微脉冲激光雷达探测大气气溶胶定标反演新方法
Inversion of Micro-Pulse Lidar Signals with a New Calibration Method
激光雷达 微脉冲激光雷达 大气气溶胶 后向散射系数 标定值 lidar micro-pulse lidar aerosol backscatter coefficient calibration value
摘要
利用一种新的自适应定标反演方法在有效探测高度内确定标定值，反演微脉冲激光雷达(MPL)回波信号，并同另外一台激光雷达系统在相同时间、相同地点的探测结果进行了对比。对比结果显示利用该方法得到的结果能够同大气实际情况吻合地较好。应用该算法对连续12 h的观测(共25组)数据进行批处理，结果正确反映了当时的天气状况。这说明该算法应用于MPL信号处理时具有很好的稳定性。
Abstract
A new self-adaptive method to determine the calibration value in the effective distance of micro-pulse lidar (MPL) is proposed. A profile of aerosol backscatter coefficient, which is retrieved from MPL signal with the boundary value determined using the new method, is compared with the one retrieved from another lidar signal with the boundary value assumed around the troposphere. The comparison shows that the two profiles seem to be consistent with each other well. A group of lidar signal, observed continuously 12 hours, is retrieved with this method, which can accurately indicate the weather conditions. The result shows that the method has a good stability.
