基于MASS方法湍流强度廓线反演影响因素的分析

Analysis of Influencing Factor for Inversion of Turbulence Profile Based on MASS

讨论了通光孔径尺寸和湍流高度分层模型对权重函数的影响。在此基础上利用奇异值分解法,反演了不同通光孔径尺寸和湍流高度分层模型下的湍流强度廓线,并进一步分析了通光孔径尺寸和湍流高度分层模型对反演结果的影响。结果表明:采用较小孔径比、等比湍流高度分层模型的权重函数反演得到的湍流强度廓线更为合理。

Influences of aperture size and hierarchical model of turbulence on weighting functions are discussed. Based on these,using singular value decomposition,vertical turbulence profiles for different aperture sizes and hierarchical models of turbulence are inversed and influences of hierarchical models of turbulence and aperture sizes on inversion results are discussed.The results indicate that vertical turbulence profiles are more reasonable based on weighting functions of smaller aperture ratio and geometric hierarchical model of turbulence.
