Underwater Acoustics
- UW00 - Underwater Acoustics, REGULAR (not structured)
Description: Contributed session on the topic. - UW01 - Impact of environmental variability on midfrequency sonar performance
Joint with: AO
Org. by Dajun Tang, Paul Hines & Peter Nielsen
Description: Environmental impact on mid-frequency (1-20 kHz) sonar performance in shallow water. - UW02 - Impact of internal waves on shallow water propagation
Joint with: AO
Org. by James Lynch & Thomas Folégot
Description: Shallow water internal waves are common and often quite strong. They greatly affect shallow water propagation in a fully 3-dimensional manner. Modern measurements show this quite clearly, also as a function of frequency. - UW03 - Geoacoustic sediment modeling
Org. by Nicholas Chotiros & Jean-Pierre Sessarego
Description: Measurements, modeling and inversion of geophysical and geoacoustic sediment interactions and related issues. - UW04 - Seabed and sea surface interaction measurements and modeling
Joint with: AO
Org. by Peter Dahl & Michael Ainslie
Description: This session will emphasize modeling and interpretation of measurements of underwater acoustic interaction with marine boundaries. A particular focus will be on short range studies for which details of the interaction are identified, although contributions pertaining to multiple interaction are encouraged. - UW05 - Sound propagation in 3-dimensional environments
Org. by David Calvo & Michael Taroudakis
Description: Talks are welcome on observation of three-dimensional propagation effects at sea, three-dimensional environmental characterization, and numerical methods for solving three-dimensional propagation problems. Topics may include but are not limited to: forward scattering by seamounts, propagation in the presence of eddies, azimuthal refraction, low- frequency sound propagation near islands, acoustic intensity fluctuation caused by three-dimensional internal waves, challenges of azimuthal resolution in models at long ranges, and efficient numerical algorithms for fully three-dimensional propagation. - UW06 - Acoustic vector fields and sensor processing
Joint with: SP
Org. by Kevin Smith & Jean-Pierre Hermand
Description: This special session will focus on advances in the understanding and modeling of the acoustic vector field, the means of measuring the acoustic vector field, and the processing schemes being developed to exploit the acoustic vector field in ocean environments. - UW07 - Broadband underwater communications
Joint with: SP
Org. by Hee Chun Song & Sergio Jesus
Description: New developments in underwater acoustic communications. - UW08 - Acoustic data fusion
Org. by Eric Maillard & Benoit Zerr
Description: New or developing methods for multisensor cooperation and data fusion. - UW09 - High frequency variability
Org. by Marcia Isakson & Thomas Folégot
Description: Impact of the environment on high frequency propagation. - UW10 - Sonar system and transducer calibration methodology
Org. by Kenneth Foote & Stephen Robinson
Description: New or developing methods, including novel applications of existing methods, for the calibration of active or passive sonar systems. - UW11 - Fifty years of progress in sonar acoustic research: The role of NURC/SACLANTCEN
Org. by Henrik Schmidt & Finn Jensen
Description: With NURC approaching its 50th anniversary it is appropriate to assess its contributions to sonar acoustic research on both sides of the Atlantic. - UW12 - Scattering from objects near boundaries
Org. by Eric Thorsos & Mario Zampolli
Description: Experimental results and/or modeling results at any frequency for scattering from localized objects near boundaries such as the seabed or the sea surface. - UW13 - Noise suppression, robust direction of arrival, and target strength estimation
Org. by Norman Owsley & Georges Bienvenu
Description: Noise ANS may distord the mainlobe, yielding large errors in both DOA and TS estimation. This may be a problem especially in fishery research but also in underwater positioning and seafloor mapping and characterization. This session invites paper about these problems both about signal processing methods and technological solutions. - UW14 - Determination of acoustic properties of materials for sonar applications
Org. by Kenneth Foote & Stephen Robinson
Description: This session covers test methods to determine the acoustic properties and performance of materials used in sonar applications, for example for baffles, windows and absorbers. - UW15 - Tank experiments
Org. by Raymond Soukup & Jean-Pierre Sessarego
Description: This session is divided into two main parts; the first one will focus on the modeling of target scatter and the second one on the benchmarking of environmental acoustics models. - UW16 – Low-frequency and high-frequency synthetic aperture sonar
Org. by Peter Gough & Roy Edgar Hansen
Description: High resolution imaging of the seafloor and of buried objects by synthetic aperture techniques. - UW17 - Numerical methods in underwater scattering
Org. by Andrew Seybert, Martin Ochmann & Bodo Nolte
Description: The Target Strength is the most common physical value in sonar techniques for describing the acoustical back- or forward scattering strength of an obstacle totally or partially submerged in water. Recent numerical methods are investigated for the lower, the middle and the high frequency range. - UW18 - Sensor coalition
Org. by Henrik Schmidt & Stéphane Jespers
Description: This session looks at sensing methods in underwater acoustics with an emphasis on the benefits of sensor combinations (including multistatic) and the tradeoffs imposed by networking in the maritime domain. Clustered together, various sensor fields will offer the opportunity to further exploit the advantages of different sensing physics. Papers illustrated with examples of performance modeling and/or field work validation are welcome. - UW19 - High frequency scattering
Org. by Anthony Lyons, Philippe Blondel & Nicholas Pace
Description: This session will present the latest experimental and theoretical research in high-frequency scattering underwater, on/in the seabed and on/in targets. - UW20 - Synthetic aperture sonar and radar convergences
Org. by James Candy, Hugh Griffiths & René Garello
Description: This session is related to the comparison between Synthetic Aperture Radar and Sonar techniques in order to achieve similar level of products: interferometry, 3D reconstruction, imaging... - UW21 - Automatic target recognition, sensors and algorithms
Org. by Gerald Dobeck, Marc Pinto & Yvan Petillot
Description: This sessions addresses the entire process of detection and classification of underwater targets including sensor design, deployment strategies, signal design, target scattering and automatic target recognition algorithms. Applications include diver detection, harbor surveillance, marine mammals detection as well as minelike targets. - UW22 - Nonlinear acoustic methods in searching for buried objects
Org. by Benjamin Dzikowicz & Eugeniusz Kozaczka
Description: The session will consist of papers devoted to theory application of methods of nonlinear acoustics and parametric sonars for sea bed structure investigation, especially for searching of buried objects like mines, pipes, archeological objects and so on. - UW23 - Auralization of sonar signals
Org. by Paul Hines & Paul White
Description: Human operators and marine mammals are able to outperform man-made systems in variety of sonar classification tasks, both passive and active. This session will discuss bio-inspired techniques in which sonar signals are represented using psychoacoustic or audiological models.
