Annotation
Experimental data of low frequency pulse signals propagation in a region of Pacific Ocean are represented. Calculations of the signal space-temporal structure and intensities of bottom re-flections were performed in the geometric acoustical approach. For two models of the wave-guide satisfactory accordance between experimental and theoretical results were received. This allows to estimate the characteristics of the bound and the effective waveguide depth for the range of frequencies in 5-40 Hz. Keywords: pulse signal, space-temporal structure, intensity, deep ocean channel, geometric acoustics approach
