利用低空激光大气传输模型，对1.06 μm激光在大气中传输时散射辐照度的分布进行了数值计算，通过与相同条件下的激光器回波信号能量进行比较，发现计算结果在理论分析上存在较大差异，其原因是未考虑激光器的单脉冲特性。通过对在单脉冲工作方式下的激光散射能量公式进行改进，提高了散射探测的计算精度。

Based on low-altitude laser atmospheric transmission models, distributions of scattering irradiance of 1.06 μm laser in atmospheric transmission are calculated. By comparing with echo signal energy of lasers at the same conditions, calculation results are found to be different from the results of theoretical analysis. The reason is that single pulse characteristics of lasers are not considered. By improving the formulas of laser scattering energy at single pulse operation mode, the calculation accuracy of scattering detection is enhanced.
