Doppler Sounding Acoustic Radar

Abstract

Sounding of the wind speed of the boundary layer atmosphere is very important for studies on problems of atmospheric eddies, atmospheric diffusion and contamination. The tangential shift of wind speed at low altitudes has a direct effect on safe flight of aircraft. Since the 1970's, Doppler sounding acoustic radar has been rapidly developed and extensively applied. On the foundation of acoustic radar sounding of temperature, the authors attained preliminary results in developing the Doppler sounding acoustic radar; the sounding altitude of vertical wind speed may attain 500 to 600 meters. Besides, dual point Doppler sounding acoustic radar has also been used to conduct measurements of horizontal wind speed and wind direction. Chinese translations.
