Аннотация:Results are presented from an experimental study of the propagation of acoustic pulses on the shallow marine shelf of the Black Sea and a coastal wedge. Signals associated with bathymetric refraction are analyzed. Short-period signal fluctuations on a Black Sea coastal wedge along stationary acoustic tracks with a mean bottom slope of ~25° are studied. The spectra and characteristic periods of fluctuations in the amplitude, azimuthal angles, angles of slide, and arrival times of pulsed signals are determined. The main reasons for fluctuations in the characteristics of signals unde
