　　分析了Hufnagel-Valley大气湍流模型参数反演的必要性，根据实时测量的大气相干长度和等晕角，反演该模型中的两个可调参数，并提出了改进的反演计算公式。数值仿真结果表明，改进公式弥补了原有公式在近地面湍流较弱时，不能有效反演高空风速参数的不足；适合于反演不同的湍流条件，提高了湍流强度廓线的反演精度：以两种典型的风速模型为例，改进公式反演的参数，相对误差均在0.5%以内；同时改进公式也减弱了相干长度和等晕角测量误差对反演的影响。

The necessity to inverse the parameters of Hufnagel-Valley atmospheric turbulence model was analyzed. The two adjusted parameters were inversed according to real-time measurement of atmospheric coherence length and isoplanatic angle. Furthermore, an improved inversion equation was proposed. By numerical simulation, the results show that the improved equation covers the shortage which the original equation can't inverse the high wind parameter effectively when turbulence near the ground is weak. It is suitable for inversion of different turbulence conditions, and improves the accuracy of turbulence profile:taking two typical wind model as examples, the relative error of parameters inversed by improved equation are within 0.5%; the improved equation also weakens the influence due to measurement errors of coherence length and isoplanatic angle.
