Possibilities of crosswind profiling based on incoherent imaging

摘要

Possibilities of the wind speed profiling along an observation path of a distant object from the analysis of a video sequence of images of the object are studied in this work by numerical simulation. The method is based on the analysis of two neighbor frames of a video sequence of incoherent images. It is more rapid than analogous methods, due to the absence of need in accumulation of the statistics of parameters analyzed. It is shown that the drift speed of several (no less than 3) turbulent layers, located at different distances between the object observed and the receiving optical system, can be determined for some turbulent conditions and object parameters. The method accuracy is estimated for wide ranges of atmospheric conditions and parameters of the object observed.
