Underwater acoustic propagation modelling and prediction
Article Abstract:
Research into the frequency-dependent characteristics of sound propagation in a ocean environment can be enhanced through the use of numerical acoustic models. SACLANTCEN has played a leading role in the formulation of acoustic models such as C-SNAP, KRAKEN, PAREQ and SAFARI. Modelling and ocean experimental programs are highly interdependent. Substantiation of numerical codes is very important in model development since a correlation with experimental data will reveal whether the model incorporates all the physics needed to interpret the propagation techniques in a specific ocean environment.

Prediction of the underwater environment
Article Abstract:
Rapid environmental assessement (REA) techniques are being used to measure and collect data on the littoral zone which could be used to promote maritime military operations. One of the most important elements in REA is satellite remote sensing, a technology which provides spatial and temporal data on a global scale in regions which are strategically not available. Synthetic aperture radar is the tool preferred in military applications and sea surface surveillance because of its capacity for high spatial resolution and all-weather/day-night imaging.

Magnetic detection techniques in antisubmarine warfare
Article Abstract:
SACLANTCEN conducted in 1993 an experimental research program on the marine magnetic environment with the aim of evaluating passive magnetic methods to detect and conduct surveillance of submarines in littoral zones. An automonous, self-recording tri-axial prototype probe called the Ocean Bottom Magnetometer was developed to conduct magnetic field measurements in the ocean. The magnetic measurements can be conducted from surface ships and submarines.
