| 摘 要： | 通过对多次后向散射激光雷达接收信号的各级散射的分析，在高次散射接收信号与单次散射接收信号之间建立了一个简单的比例关系，即它们的比值与总衰减系数成比例；用蒙特卡罗方法对激光雷达接收信号进行了模拟．结果显示，１，２，３次散射起主要作用，随着总衰减系数的增大，高次散射对激光雷达接收信号的作用也越来越强． |
| 关 键 词： | 激光雷达；接收信号；多次后向散射；单次散射；总衰减系数；蒙特卡罗方法 |

| Abstract: | A simple proportional relationship is established between the higher scattering and the single scattering by analyzing each level scattering of the multiple backscattering lidar received signals. The ratio is proportional to the attenuation coefficient; Monte Carlo method is used to simulate lidar received signals. The simulation results show that the first, second and third scattering exert major influence, and the influence of higher scattering on the lidar received signals is strengthened with the increase of overall attenuation coefficient. |
| Keywords: | lidar received signals multiple backscattering single scattering attenuation coefficient Monte Carlo method |
