A new three-channel monostatic Doppler sodar is described. The sodar is designed for remote measurements of the wind velocity profile and structure constant of temperature fluctuations, as well as for detecting temperature stratification of the boundary atmospheric layer. The Volna–3 sodar includes a minimum set of analog electronic blocks, which only provide for emission, reception, and pre-filtration of acoustic signals. Another its feature is digital conversion of a high-frequency acoustic signal into an equivalent low-frequency complex form. The information processing algorithms developed allow real-time measurements to be conducted without the use of specialized computer devices.
