Abstract
The frequency dispersion of the sound propagation speed in a marine waveguide makes it possible to compress an acoustic signal with an increase in its intensity. The paper presents the results of experimental research of this effect during the propagation of a broadband acoustic signal from a parametric array in shallow water. The parametric array provided single-mode excitation for the marine waveguide. The possibility of compressing a broadband signal during its propagation in shallow water with special selection of the frequency modulation mode is discussed. Waveguide dispersion leads to an increase in the efficiency of parametric radiation in shallow water.
