Abstract

Experimental data on long-range propagation of explosion-generated signals in a well-developed underwater sound channel are analyzed. In the experiments, the wind speed reached 10–11 m/s and the sea state was Beaufort 4–6. At distances of 80–120 km from the source and at two different reception depths, a prereverberation is observed, that is, the advancing of a part of the bistatic surface reverberation with respect to the direct signal. The conditions for the prereverberation to arise are discussed for different distances from the source. On the basis of data processing, the increase rate of the prereverberation signal, its level relative to the direct signal, and frequency dependence are estimated.
