Abstract
Some peculiarities of measurement of atmosphere temperature profiles with help of Doppler method of radio-acoustic remote sensing in short-wave range are investigated. For this purpose the expression of power spectrum of received signal is investigated at the point where the wind drag is compensated. We suppose that the periodical series of electromagnetic pulses is scattered on the single acoustic pulse and take into account the mutual influence of turbulence and wind in atmosphere. We find that turbulence and wind lead to widening of the frequency spectrum of the received signal. Naturally this circumstance decreases the exactness of this method. It is also shown that for the determination of local atmospheric temperature in this range of wave it is necessary to use the particular sound frequency for each altitude. Moreover, we find that this method depends heavily on the magnitude and direction of the wind. Calculations show that for obtaining an exact temperature profile it is necessary to use the short-wave narrow-angle antennas.
