Abstract

A method of measurement is proposed, based on the measurement of the motion of an acoustic pack under the influence of wind. The described meter refers to the field of applied meteorology and can be used in several sectors of the economy: in aviation for remote measurement of wind speed over runway, in the locations of metallurgical and chemical enterprises for forecasting wind emission zones of harmful emissions, as well as in justifying the location of windmills in wind power systems. The results of research and development of the acoustic sounding system for measuring the parameters of the wind situation in the boundary atmospheric layer are presented. The structural diagram of the system of the atmosphere acoustic sounding is given. The analysis of the wind situation in the boundary atmospheric layer is carried out. The signal-to-noise ratios for different heights are calculated. The location of the acoustic package for changing the length of the radius vector is calculated. The wear rate of the acoustic package at different heights and the dependence of the measurement error on the signal-to-noise ratio were analyzed. Errors are calculated for wind speed components in different planes, as well as correlated error values for different signal / noise ratios. The calculated data completely satisfy the requirements set in the research and development of this system of acoustic sounding of the atmosphere and measurement of wind speed in the boundary layer of the atmosphere by the method of acoustic location.
