The results of experimental research of acoustical pulse propagation along to the coastal wedge are presented here. The research has been done with extended bottom receiving array at the Black sea shallow water range. We defined the direction of arrival sequences of acoustical pulses, excited in water by seismic airgun. The acoustical pulses registration is provided by extended receiving array installed next to the bottom cross the coastal wedge isobaths. Seismoacoustical source moved from the array by the boat along to one of the isobaths. It is shown the variation of the receiving signal intensity distribution along to the array aperture both and variation of arrival angles with the distance increasing to the source.
