利用低空激光大气传输模型,对1.06μm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.
利用低空激光大氣傳輸模型,對1.06μm激光在大氣中傳輸時散射輻照度的分佈進行瞭數值計算,通過與相同條件下的激光器迴波信號能量進行比較,髮現計算結果在理論分析上存在較大差異,其原因是未攷慮激光器的單脈遲特性.通過對在單脈遲工作方式下的激光散射能量公式進行改進,提高瞭散射探測的計算精度.

Based on low-altitude laser atmospheric transmission models, distributions of scattering irradi?ance of 1.06μm 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 scatter?ing energy at single pulse operation mode, the calculation accuracy of scattering detection is enhanced.
