On the feasibility of using FLIR (forward looking infrared) data for crosswind measurements

We report here the results of a study of the feasibility of measuring crosswinds by observing fluctuations in the image formed by a lens observing an arbitrary scene. The study is especially concerned with observations in the 10 pm wavelength region used by the FLIR thermal sight system, and how this passive system might be used to obtain crosswind information. This report is submitted to fulfill the requirements of Project Order ASL798003 issued by the U. S. Army Electronics Command, Atmospheric Sciences Laboratory, White Sands, New Mexico.
