摘要/Abstract

摘要：

一台532 nm单波长的偏振米散射激光雷达用于测量大气后向散射回波信号和线性退偏振比?。为了准确获得大气气溶胶和云的退偏振特性，两个偏振通道的标定因子k必须精确确定。采用三种不同的实验方法来确定偏振激光雷达的标定因子，详细叙述了测定方法、过程、结果及误差分析。最后，将标定后的激光雷达探测结果与CALIPSO数据进行比较，进一步验证了方法的可行性。

关键词: 标定因子, 退偏振比, 偏振米激光雷达, CALIPSO

Abstract:

A ground-based polarization-Mie lidar has been developed to measure backscattering signals from the atmosphere and linear depolarization ratios ? at 532 nm. To retrieve depolarization properties of clouds and aerosols, the calibration factor k of two polarization channels at 532 nm must be calculated. Three different experimental methods are presented to determine the calibration factor k in this polarization-Mie lidar. Some measured examples are presented and discussed. Experimental and validated results indicate these methods are feasible.

Key words: calibration factor, depolarization ratio, polarization-Mie lidar, CALIPSO
