PC-based propagation and sonar prediction models
(NATO. SACLANTCEN, 1995/12)
Six acoustic models available for use on PC's are tested on a series of typical propagation situations from the North Atlantic and the Mediterranean. The model set includes both early US Navy models (ASTRAL, FACT, RAYMODE) ...
RAPID RESPONSE, september 1996: modelling of broadband transmission loss along selected tracks in the Strait of Sicily
(NATO. SACLANTCEN, 1997/07)
A large set of experimental acoustic broadband data in the 50-3200 Hz band is analyzed with the objective of deriving average geoacoustic models for three sites in the Strait of Sicily. The experimental data were obtained ...
Performance assessment of the LYBIN - 2.0 propagation-loss model
(NATO. SACLANTCEN, 2001/07)
A new acoustic model LYBIN has been proposed for inclusion in the AESS model set. In order to determine this model's prediction accuracy and computational efficiency, SACLANTCEN was tasked to test LYBIN on exactly the same ...
Performance assessment of propagation models in AESS-6.0
(NATO. SACLANTCEN, 1999/08)
A set of AESS propagation-loss predictions has been generated for typical operational scenarios in both deep and shallow water, for two sonar frequencies (500 and 3500 Hz) and for several source-receiver combinations. ...
Mode and PE predictions of propagation in range-dependent environments: SWAM'99 workshop results
(NATO. SACLANTCEN, 2000/05)
Three numerical acoustic models, a coupled normal-mode model (C-SNAP),
Geoacoustic models for selected shallow water areas
(NATO. SACLANTCEN, 1996/07)
