Abstract
In a paper the acoustic method of measurement of speed and a direction of moving of turbulent air is discussed. It is proposed to increase resolution measuring device with shifting of frequency of heterodyne signal on 1%. For supervising of weak air turbulence it is suggested to measure phase difference of signal with respect to reference one.
