Abstract
Experimental data are presented on time and frequency dependences of the reverberation level for bistatic transmission and reception at low acoustic frequencies. The data are obtained from the studies carried out in a coastal shallow-water region and in the central region of the Barents Sea with explosion-generated and pulsed cw signals. By using the simplest computational model, approximate estimates are obtained for the effective coefficient of spatial attenuation and the effective scattering coefficient in the frequency band 40–400 Hz.
