Paper Abstract

Recently, the upper atmosphere wind field has attracted increasingly attention of the researchers. The history, status and the future of temporal phase-stepping measurement methods used for upper atmosphere measurement(UAM) are introduced. The traditional four intensities method which is field-widened, achromatic, temperature compensation wind imaging is presented comparatively. This paper mainly expounds the principle and method for three arbitrary phase-stepping measurement methods. Analysis and calculation of the wind temperature and velocity are described emphatically. The more terse and precise measurement method has scientific significance and practical value for physical geography, atmospheric science, environment protection, national defense and national economic construction.
