摘　　要：依据辐射传输与测量和标定原理,推导出激光雷达散射截面测量数学模型与不确定度表达式,对影响测量不确定度因素进行了较全面的分析,并提出修正与提高方法。In this paper, we focus on measurement uncertainty of laser radar cross section. Firstly, based on the princi- ple of radiation measurement and calibration, mathematic model and uncertainty expression of laser radar cross section are derived. Then the factors that affect the uncertainty of measurement are analyzed. Finally, the correction method is proposed.
