Abstract
The fluctuations of intensity of broadband pulses in the mid-frequency range (2 - 4.5 kHz) propagating in shallow water in the presence of intense internal waves moving approximately along the acoustic track are considered. These pulses were received by two separate single hydrophone units (SHRUs) placed at different distances from the source (∼4 km and ∼12 km) and in different directions. It is shown that the frequency spectra of the fluctuations for these SHRUs have different predominating frequencies corresponding with the directions of the acoustic track. Comparison of experimental results with theoretical estimates demonstrate good consistency.
