Ambient Sound Modeling in Complex Ocean Environments

Using state-of-the-art acoustics propagation simulations and complex oceanographic models, the Underwater Acoustics and Signal Processing branch at NRL seeks to better understand how local environmental processes are imprinted on ambient sound data. Temporal and spatial variability of the acoustic propagation environment result in significant variability to the received acoustic signal time series. This effort will create a more comprehensive understanding of the changes in received acoustic time series due to the presence and lo...
