介绍了平行轴与共轴激光雷达几何重叠因子的物理意义,并从几何推导和实验测量两方面给出求解几何重叠因子的方法。通过对AML-1激光雷达(共轴系统)的实验总结,列举了一些有关几何重叠因子的典型结果,并分析了激光雷达几何重叠因子对探测气溶胶消光系数的影响。最后得出,气溶胶消光系数对几何重叠因子的修正非常敏感,但在激光雷达系统稳定且操作规范的情况下,几何重叠因子随距离的分布曲线是相对稳定的,此时对气溶胶消光系数的影响也较小。
The physical meaning of geometric overlap factor between parallel axis and coaxial laser radar is introduced, and the method to solve geometric overlap factor is given from two aspects of geometric derivation and experimental measurement. Through the experimental summary of the AML-1 laser radar (coaxial system), some typical results about the geometric overlap factor are listed, and the influence of lidar geometric overlap factor on the detection of aerosol extinction coefficient is analyzed. Finally, it is concluded that the aerosol extinction coefficient is very sensitive to the geometric overlap factor correction. However, the geometric overlap factor with the distance distribution curve is relatively stable when the lidar system is stable and operating. At this time, the aerosol extinction coefficient The impact is also small.
