Reconstruction of Cross-Wind Profile from Turbulent Intensity Fluctuations of Diffusely Scattered Optical Wave

摘要

The problem of measuring the mean (averaged over path) wind velocity based on the spatio-temporal statistics of fluctuations of intensity of optical wave or light scattered off a viewed object surface or natural scene in a turbulent atmosphere was investigated in. The results of wind profiling by SCIDAR technique are presented, in particular, in. In this paper we consider the problem of wind profiling from the turbulent intensity fluctuations of reflected wave. We present the basic equations for reconstruction of wind velocity and direction profiles from the spatiotemporal spectrum of intensity fluctuations of optical wave scattered by a diffuse target in a turbulent atmosphere. We analyze the intensity of scattered wave being recorded in the focal plane of the receiving telescope. The results of end-to-end computer experiments on reconstruction of wind profiles we present as well.
