Abstract
Abstract : Long-term goals of this research are: provide the underwater acoustic research community and the US Navy with a practical 3D propagation model that can be used over a broad frequency range in passive and active sonar performance prediction, acoustic communications channel modeling, and in understanding operational concepts impacted by 3D propagation effects. provide these predictive capabilities for both pressure and particle velocity sensors. The initial objective was to implement a 3D Gaussian beam model on multi-core, high-performance computing hardware in order to support mid and high frequency applications like reverberation modeling and acoustic channel simulation. As graphic processing unit or GPU hardware rapidly emerged as a compelling platform for such work, my objective became to adapt selected acoustic wave propagation models onto GPUs.
