DURIP Autonomous Modularized Acoustic Transceiver Systems (AMATS)
Abstract
Funds to procure and fabricate essential components for four autonomous acoustic transceiver systems are proposed to improve the fieldwork capability for ocean acoustic studies in complex environments sponsored by the Task Force Ocean (TFO) and Ocean Acoustics (OA) Programs in the Office of Naval Research (ONR). Each of these systems will consist of a central control unit that communicates with and controls both transmitting and receiving front ends. Both components are modularized to increase the flexibility for deployments. One can choose either the transmitter or the receiver, or deploy both of them simultaneously. The systems are autonomous and compact, so they can be put on a variety of autonomous platforms, including unmanned underwater vehicles (UUVs), unmanned surface vehicles (USVs), wave gliders, drifters, and light weight moorings. The system design is centered on the concept of modularization and synchronization. All systems will be equipped with Chip Scale Atomic Clocks (CSACs). Potential applications can be marine environmentsurveys (e.g., seafloor and sub-bottom profiling) as well as acoustic communication and navigation, as well as sound propagation study. Future ONR acoustics experiments include three-dimensional acoustics in submarine canyons, shelfbreaks and slopes, as well as in high latitude environments. With a network of these system, we can also pursue studies of the temporal and spatial variability dueto dynamic sea surface conditions, water-column fluctuations, and bathymetric and sub-bottom variability, and ultimately distinguish different environmental effects on undersea sound propagation and scattering.This abstract is publicly releasable.
