Abstract
A method for estimating the intensity of the structural characteristic of the fluctuations of the refractive index Cn2 from the data of a two-channel turbulent aerosol lidar operating on the effect of backscattering enhancement (BSE) is shown. It is proposed to use the Vorob'ev approximation, which for the case of homogeneous turbulence determines the dependence of Cn2 on the ratio of echoes. The basis for this was experimental data, from which it follows that the BSE effect occurs in a relatively small area of space near the scattering volume. The results of sounding along a horizontal path are presented.
