Frequency measurements performed during radioacoustic sounding of the troposphere using low-frequency sound and decameter radio waves are analyzed. An expression is derived for the power spectrum of the received signal, when a periodic sequence of electromagnetic pulses is scattered by from a single sound pulse, at the point of compensation of wind drift taking into account atmospheric turbulence. It is shown that to achieve a prescribed accuracy in measurements of the temperature of the atmosphere it is necessary to construct antennas with narrow directional patterns.
