激光雷达信号随机误差的估算
Estimation of Random Errors for Backscatter Lidar Observations
摘要
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.
Abstract
Based on the analysis of random errors and characteristic of lidar data,a new method of estimating random errors is introduced,which is called noise scale factor method.Using background signals in far range in one measurement,the noise scale factor is obtained,and the uncertainty of lidar signals at any distances can be estimated.The experiment results show that this method is reliable and feasible.
