Abstract

We develop differential column image motion (DCIM) lidar for monitoring atmosphere refractive structure constant C_n² profile. It is important to use an appropriate regularization method for DCIM lidar since the ill-posedness of the integral equation between the C_n² profile and the measured r₀ profile. In this paper, three typical regularization methods are studied to retrieve the C_n² profiles from r₀ profiles.The experiments illustrate that the Tikhonov method and truncated SVD method perform good performance, while damped SVD shows poorer inversion accuracy.
