Abstract

A way of estimating the intensity of the structure characteristic of fluctuations of the refractive index \(C_{n}^{2}\) based on data from a two-channel turbulent aerosol lidar operating on the backscatter enhancement (BSE) effect is shown. It is proposed to use V.V. Vorob’ev’s approximation which, for the case of homogeneous turbulence, determines the dependence of \(C_{n}^{2}\) on the ratio of echo signals. This technique is based on experimental data which suggest that the BSE effect appears in a relatively small region of the space near the scattering volume. Results of sounding for a horizontal path are presented.

从激光雷达数据估算湍流强度

摘要

示出了一种方法，该方法基于来自具有反向散射增强（BSE）效应的两通道湍流气溶胶激光雷达的数据来估计折射率\（C_ {n} ^ {2} \）的涨落的结构特征的强度。建议使用VV Vorob'ev近似，对于均匀湍流，该近似确定\（C_ {n} ^ {2} \）对回波信号比率的依赖性。该技术基于实验数据，表明BSE效应出现在散射体积附近空间的相对较小区域。给出了水平路径探测的结果。
