Experimental demonstration of the focused acoustic field in the ocean
Akal, Tuncay; Ferla, Melchiorre C.; Kuperman, William A.; Hodgkiss, W. S.; Song, H. C.; Jackson, Darrell R. (NATO. SACLANTCEN, 1998/10)An experiment conducted in the Mediterranean Sea in April1996 demonstrated that a time reversal mirror (or phase conjugate array) can be implemented to spatially and temporally refocus an incident acoustic field back to ... -
Temporal and spatial variabilities in shallow water acoustics: measurements and predictions
Ali, Hassan B.; Ferla, Melchiorre C.; Akal, Tuncay (NATO. SACLANTCEN, 1985/03)An acoustic signal propagating in the sea is generally degraded not only by interactions with the bottom and surface boundaries, but also by volume inhomogeneities caused by non-uniformities in temperature, density, and ...
