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. ...
Acoustic impact of upper ocean models
(NATO. SACLANTCEN, 1989/12)
The upper mixed-surface layer of the ocean, with its homogeneous vertical temperature profile, provides a somewhat special acoustic propagation environment where the sound speed will increase (due to pressure) down to the ...
PROSIM broadband normal-mode model: a user's guide
(NATO. SACLANTCEN, 2000/02)
PROSIM is a layered normal-mode model approach for adiabatic broadband range-dependent sound
Geo-acoustic inversion of the PROSIM'97 experimental data using simplex simulated annealing
(NATO. SACLANTCEN, 2000/01)
In the spring of 1997 SACLANTCEN performed an experiment near the Elba island in the Mediterranean Sea. The PROSIM'97 experiment was designed for the validation of a broadband acoustic propagation model. During the period ...
Wave theory modelling of convergence zone propagation in the ocean
