Approximating Acoustic Uncertainty in Shallow Ocean Environments
In recent decades, sophisticated computational routines for underwater acoustics have been developed, and advances in computational power have put real time use of these routines in reach for sonar applications. However, the US Navy must often operate in unfamiliar waters where the basic environmental inputs to the computational routines may be uncertain or unknown. In this situation, the value...
متن کاملImplementation of an adaptive burst DQPSK receiver over shallow water acoustic channel
In an environment such as underwater channel where placing test equipments are difficult to handle, it is much practical to have hardware simulators to examine suitably designed transceivers (transmitter/receiver). The simulators of this kind will then allow researchers to observe their intentions and carry out repetitive tests to find suitable digital coding/decoding algorithms. In this p...
متن کاملAcoustic Techniques for Uncertainty Shallow Ocean Environments
The overall long-term goal for this project is to develop engineering tools that are useful to the Navy as it operates in uncertain and/or unknown ocean environments. During the last year, this project has changed its emphasis from predicting the impact of environmental uncertainty on acoustic propagation calculations to determining the utility of a time-reversal-based technique for source trac...
متن کاملInelastic scattering in ocean water
Over clear ocean waters, photons scattered within the water body contribute significantly to the upwelling flux. In addition to elastic scattering, inelastic Vibrational Raman Scattering (VRS) by liquid water is also playing a role and can have a strong impact on the spectral distribution of the outgoing radiance. Under clear-sky conditions, VRS has 5 an influence on trace gas retrievals from s...
متن کاملModeling and Simulation of Motion of an Underwater Robot Glider for Shallow-water Ocean Applications
This paper describes the modeling and simulation of an underwater robot glider used in the shallow-water environment. We followed the Equations of motion derived by [2] and simplified dynamic Equations of motion of an underwater glider according to our underwater glider. A simulation code is built and operated in the MATLAB Simulink environment so that we can make improvements to our testing gl...
