Abstract
The possibility is considered of increasing the efficiency of a parametric antenna when exciting acoustic modes in a shallow marine waveguide. It is shown that the complete compression of acoustic signals propagating in the shelf sea can be achieved with a corresponding increase in their intensity if a special mode of frequency modulation is selected. Results are presented from an experimental study of this effect in the propagation of a broadband acoustic signal of a parametric antenna in the shelf sea.
