摘要：
Atmospheric turbulence is an important parameter of laser propagation in the atmosphere. This paper reports the self-developed scanning DIM-LiDAR system. Through the research on spot image processing technology and range gated imaging technology involved in the detection of atmospheric turbulence by LiDAR, the limb scanning detection algorithm is proposed, which can effectively detect atmospheric turbulence. It can ensure that the accuracy of the sampling thickness of the light column reaches 0.75 m. The comparison experiment shows that the development trend of atmospheric turbulence detected by scanning DIM-LiDAR system and ultrasonic anemometer is consistent, and the correlation is better than 0.69. Compared with the atmospheric turbulence model of sounding data, their vertical distribution characteristics are the same in the development trend. This paper can provide the theoretical and experimental bases for subsequent related research.
