Interference image spectroscopy for upper atmospheric wind field measurement

Based on the observation of natural airglow and auroral visible emission lines in the upper atmosphere as the explored source, we have surveyed the upper atmosphere wind field through interference imaging spectroscopy coupled with the Doppler effect of electrical and magnetic waves. The velocity and temperature of the upper atmospheric wind field are analyzed and studied. The survey theory and calculation formula of atmosphere wind field in all directions and multi-directions are presented when the relative velocity of the explored source to the detector and their linking line have an arbitrary angle. We also analyzed the effects of the measurement of the upper atmospheric wind field using computer simulation, and explained the reason why the auroral emission line is thought as Gaussian profile.
