Underwater Acoustic Signal Processing Workshop
Listings Underwater Acoustic Communications: Working at the Intersection of Physics, Signal Processing, and Communications Theory James C. Preisig Woods Hole Oceanographic Institution WHIO, MS #11 Woods Hole, MA 02543 [email protected] The underwater environment is widely regarded as one of the most difficult communication channels. Underwater acoustic communications systems are challenged by t...
متن کاملModel-Based Processing for Underwater Acoustic Arrays.
This short monograph is in the form of a Springer Brief on ModelBased Processing for Underwater Acoustic Arrays. The fundamentals of array signal processing (Chap. 2), statistical signal processing, and modelbased processing (Chap. 3) are included, with a clear emphasis on modelbased Bayesian processing. The author describes the material in a lucid manner, which can be comprehended by a wide ra...
متن کاملAdvanced Signal Processing Techniques for Underwater Acoustic Communication Networks
In this thesis, we develop and investigate novel signal processing techniques for underwater acoustic communication networks. Underwater acoustic channels differ from radio communication channels in the lower speed of signal propagation, richer and often sparse multipath arrivals, and more severe Doppler effect. Therefore, many signal processing techniques developed for radio communications may...
متن کاملAutomatic Sea Floor Characterization based on Underwater Acoustic Image Processing
Automatic sea floor characterization is mainly based on the signal or image processing of the data acquired using an active acoustic system called sediment sonar. Each processing method suits a specific type of sonar, such as the monobeam, the multibeam, or the side-scan sonar. Most types of sonar offer a two dimensional view of the sea floor surface. Therefore, a high resolution image results ...
متن کاملEvaluation of underwater acoustic propagation model (Ray theory) in a river using Fluvial Acoustic Tomography System
Underwater acoustics is widely used in many applications, such as oceanography, marine biology, hydrography, fishery, etc. Different models are introduced to simulate the underwater acoustic propagation in the oceans and the seas. In this study, the Ray Theory model is used to simulate the acoustic wave propagation in a shallow-freshwater river (Gono River) located in western part of Japan. The...
