讨论了激光大气传输时的湍流与热晕综合效应问题。提出了根据湍流效应对热晕经验公式进行修正的处理方法,其物理基础是在湍流效应较明显的情况下,由相干距离决定的湍流Fresnel衍射参数远小于由发射口径决定的Fresnel衍射参数时,小尺度热晕的影响超过整束热晕占主导地位。将修正的经验公式与基于数值计算的定标公式相比较,结果令人满意。 Discusses the combined effects of turbulence and thermal halo in laser atmospheric transmission. The correction method based on the turbulence effect is proposed. The physical basis is that when the turbulent Fresnel diffraction parameter determined by the coherence distance is much smaller than the Fresnel diffraction parameter determined by the launch aperture under the condition of obvious turbulence effect, The impact of small-scale thermal halo over the entire bundle of thermal dominance. The modified empirical formula is compared with the calibration formula based on numerical calculation, and the result is satisfactory.
