A study of the uncertainty in estimate seabed properties as a result of goeacoustic inversion algorithms
(NATO. SACLANTCEN, 2003/10)
This paper investigates the inherent uncertainty in estimated seabed properties derived from matched-field geoacoustic inversion algorithms. This algorithm-induced uncertainty must be considered when interpreting inversion ...
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),
GLider Acoustics Sensing of Sediments (GLASS): experiments and data analysis
(CMRE, 2013/12)
Seabed characteristics (geoacoustic properties and scattering strength) are critical parameters for sonar performance predictions. However, this bottom information is considered very difficult and expensive to achieve in ...
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
Broadband signal simulation in shallow water
(NATO. SACLANTCEN, 2002/12)
Today's minimum requirements for ocean acoustic models are to be able to simulate broadband signal transmissions in 2D varying environments with an acceptable computational effort. Standard
Application of real data to sonar detection by neural networks
(NATO. SACLANTCEN, 1992/11)
This memorandum describes the results of applying an artificial neural network for the detection of target echoes. The present study is a continuation of work conducted in 1989 in which a three-layer artificial neural ...
Broadband geo-acoustic inversion from sparse data using genetic algorithms: results from the 1997 Geo-Acoustic Inversion Workshop
(NATO. SACLANTCEN, 1998/03)
Matched field acoustic inversion techniques were investigated
The characterization of a range-dependent environment using towed horizontal array data from the MAPEX 2000 experiment
(NATO. SACLANTCEN, 2002/11)
The characterization of ocean environments using geoacoustic inversion techniques has received a
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 ...
