Abstract

The characteristics of the radio waves scattering over the acoustic wave packets created by sophisticated acoustic sounding signals in radio acoustic sounding systems of atmosphere are analyzed. In this case, there is an expansion of the scattering body along spatial frequencies, expanding the wave numbers range of effective interaction acoustic sounding and electromagnetic signals, and a decrease in the duration of the scattered radio signals is also observed. The physical reason signal length decrease is the signal length duration spatial domain decrease of acoustic and electromagnetic waves, due to the presence of modulation parameters in space. The form and parameters of the spatial spectrum, that is embedded in the scattering signal, in a great degree acts on the quality characteristics resulting estimates of signal parameters and atmospheric parameters. The presence of specific errors in the estimation of the Doppler frequency information parameters and radio signals time delay, scattered on the complex acoustic sounding signals is shown. The use of sound oscillations can significantly increase the efficiency of the radio acoustic sounding stations when measuring vertical temperature profiles of the atmosphere
