Energy efficiency and fail-safety of modern wind turbines (WT) are largely determined by their ability to the temporal "tuning" under the spatial variability of the wind field.

The paper examines the possibility of implementing the combined radar-acoustic antenna (CRAA), which is placed on the horizontal-axis wind turbine for the horizontal radio-acoustic wind sounding system (HRASS). The main antenna feature is the use of the developed antenna parametric working mode at acoustic waves, which ensures the high directivity of the acoustic probing radiation at the limited antenna aperture. The basic version of the CRAA design, intended for installation on the horizontal-axis wind turbine includes an ring multi-element acoustic radiator, in the interior of which the pulse-Doppler radar antenna unit is installed.

The radio-acoustic hardware operates in accordance with the special quasicontinuous mode when using radio pulses of large spatial extent, together with short acoustic pulses.
