Annual Report for Ocean Acoustics

چکیده
One of the long-term goals of this project is to analyze and propose energy-efficient communication techniques for underwater acoustic sensor networks. These techniques aim at consuming as less energy as possible as well as guaranteeing a minimum quality of service. In order to do so, we assume and validate some statistics of the underwater acoustic channels and derive stochastic optimal transmission policies.

متن کاملAcoustical Oceanography and Shallow Water Acoustics
In this paper, we review some recent new results in shallow, coastal waters from both ocean acoustics (the study of how sound propagates and scatters in the ocean) and acoustical oceanography (the study of ocean processes using acoustics as a tool).
متن کاملSequential Bayesian Filtering in Ocean Acoustics
Sequential filtering provides an optimal framework for estimating and updating the unknown parameters of a system as data become available. Despite significant progress in the general theory and implementation, sequential Bayesian filters have been sparsely applied to ocean acoustics. The foundations of sequential Bayesian filtering with emphasis on practical issues are first presented covering...
متن کامل-Final Report of the Project: Sub-mesoscale Ocean State Estimation in Shelf/Slope Regions Using Variational Data Assimilation to Integrate Ocean Observing System Data: Application to SW06
The long term goal is to develop a robust ocean prediction system for the North East US coast that efficiently exploits all the available observational platforms combined with the Regional Modeling System (ROMS). The system is now operating in real-time and forecasts of the state of the ocean six days in the future are posted daily at www.myroms.org/espresso. The project summarized here support...
متن کاملOn the near field measurement for the inverse scattering problem for ocean acoustics
Recently a near field measurement approach has been proposed to deal with inverse ocean acoustics. It uses the near field of the scattered wave instead of the far field pattern. In this paper we justify how this near field of the scattered wave can be determined by the given Green’s function on some surface surrounding the object to detect. This justifies the usual measurements in ocean acousti...
