A theory of measuring turbulence information using Mie scattering lidar is introduced. The feasibility of measuring turbulence with existing AML-2 Mie scattering lidar is analyzed and some experiments are performed in the horizontal direction on March 15, 2009. The echo signal curve and results of data analysis show that, the effective range of measuring turbulence with AML-2 Mie scattering lidar is about 300～820 m. The value of normalized variance of the irradiance fluctuations, called scintillation index, is between 0.001 and 0.1. It increases with the increment of propagation distance, and the phenomenon of scintillation saturation is not obvious. The value of atmospheric refractive index structure constant is about 1.0×10-15m-2/3, and basically maintains homogenous in the horizontal direction. On the whole, the tendencies of scintillation index and refractive index structure constant with propagation distance are almost similar to the theoretical results.
