Analyses were made to determine the feasibility of three proposed methods of remote wind measurement using 1 scattering from natural atmospheric turbulence 2 electromagnetic scattering from acoustic waves and 3 infrared tracking of an artificially heated volume of air bubble. Use of natural turbulence as a sensor will require 1 additional data on distribution and characteristics of turbulence from ground level to one mile altitude, 2 correlation of turbulence motion and wind, and 3 radar state-of-the-art improvement to provide consistent detection and measurement. Remote wind measurements by microwave reflection from acoustic waves have been demonstrated, but additional experimental data are needed to determine maximum usable range and the effects of turbulence on the acoustic waves. Remote generation of a heated bubble of air does not appear feasible.
