Abstract
The correlation method of measuring the frequency shifts of the sound field maxima caused by the nonstationary oceanic medium is considered. The method is based on tracing the frequency shift of the maximum that is observed in the cross-correlation function of signal spectra received at different instants of time. The relation between the correlation method and the method based on measuring the frequency shifts of the maxima observed in the interference pattern of the source is analyzed. The sensitivity of the correlation method is estimated.
