Results of an experimental study of the spatial correlation of signals from underwater explosions are presented for vertically and horizontally (across the path) separated reception points. The measurements were carried out on two propagation paths about 200 and 110 km long in the Barents Sea for frequencies below 500 Hz. The vertical correlation radius is found to increase with the distance to the source, which is primarily caused by the decrease in the sector of arrival angles of energy carrying signals. The transverse correlation radius weakly depends on the path length for frequencies below 300 Hz, while for higher frequencies, it decreases beginning from a distance of about 40 km, which can be attributed to the effect of short-period internal waves. © 2004 MAIK “Nauka / Interperiodica”.
