Abstract

Intensity variations of high-frequency sound pulses due to the motion of internal solitons in shallow water are investigated in terms of the ray approximation. It is shown that ray distortions cause intensity fluctuations of about 3-5 dB. It is found that rays with turning points near the upper boundary of the thermocline play the dominant role in the formation of these fluctuations. Formulas for estimating the fluctuation frequencies predominantly observed in the spectrum of intensity variations are presented.
