We’re proud to announce that a new course is available.
The aim of the course is to describe and explain the principles of Underwater Acoustics in order to allow preliminary Sonar design.
- Sonar Equation & Signal Detection.
- Sonar concepts and units. The passive and active sonar equations. Signal detection, probability of detection and probability of false alarm. ROC curves and detection threshold.
- Propagation of Sound in the Sea.
- Oceanographic basis of propagation, convergence zones, surface ducts, sound channels, surface and bottom losses.
- Target Strength and Reverberation.
- Scattering phenomena and submarine (target) strength. Bottom, surface, and volume reverberation mechanisms. Methods for modeling reverberations.
- Ambient and Self Noise.
- Ambient and self-noise levels have a big impact on sonar performance in terms of range. This section also includes the impact due to the presence of artificial noise generators (countermeasures).
- Arrays and Beamforming.
- Directivity and array gain; sidelobe control, array patterns and beamforming for passive bottom, hull mounted, and sonobuoy sensors.
- Elements of ASW Analysis.
- Utility and objectives of ASW analysis, basic formulation of passive and active sonar performance predictions, sonar platforms.
A final section of Exercises mainly aimed to compute detection (and counter-detection) distances in the ASW scenarios (active sonar, passive sonar, torpedo sonar, etc.) will complete the course.
- The course duration is two weeks (5 working days each week).
- The maximum number of participants is in the order of 10 with specific technical knowledge in the field (dB, filters, frequency spectrum, etc.).
- The course documentation will be provided in English language.
