激光雷达信号随机误差的估算

在分析随机误差来源和激光雷达数据特点的基础上,介绍一种新的随机误差计算方法--噪音比例因子方法.该方法用一次测量数据列中远处背景信号算出噪音比例因子,再由噪音比例因子求出任一距离上有用信号的随机误差.用实测的激光雷达信号进行检验,结果表明,这种方法是可靠且可行的.     

Retrieving aerosol backscattering coefficient for short range lidar using parameter selection at reference point

<正>A new method is proposed based on the analysis of lidar equation which selects aerosol backscatter ratio at a reference point for short range lidar in data processing.Simulation computation and experimental comparison results show that this method is reasonable and feasible.The method is applied to short range lidars,such as atmospheric monitoring lidar-2(AML-2) and micro-pulse lidar(MPL).
