Abstract:

Turbulence density profile can be obtained by turbulence density profile lidar system through measuring a set of atmospheric coherence length. However, direct inversion from measured atmospheric coherence length data can result in a high noise gain. A new approach, which combines slope and Richardson method, has been developed and its numerical simulation were performed. By recovering two representative Hufnagel-Valley(H-V) Cn2 profiles, the average relative error between initial profile and recovery profile are 7.8%and 10.6% respectively. Numerical results demonstrate that this method has a good precision.
