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.Based on the analysis of random errors and characteristic random errors is introduced, which is called noise scale factor m range in one measurement, the noise scale factor is obtained~ and distances can be estimated. The experiment results show that this of lidar data, ethod. Using the uncertai a new method of estimating background nty of lidar signals in far signals at any method is reliable and feasible
