MRI Development of a Lightweight Towed Array Receiver (LTAR) for Wide-Area Ocean Monitoring and Imaging
The PI requests MRI funding to develop a Lightweight Towed Array Receiver (LTAR) system for rapid, wide area monitoring, and measurement of the ocean environment with acoustics. The LTAR will serve as a general purpose mobile ocean remote sensing tool to study marine life, oceanography, geologic and geophysical properties of the ocean environment, anthropogenic noise in the ocean and its effect on marine life. It will enable fundamental new scientific advances in each of these areas. The LTAR will be designed to receive signals from the sub-audible range (tens of Hertz) to above the audible (tens of kiloHertz). For passive sensing, it will be possible to sense signals over trans-oceanic scales, while for active sensing such as with OAWRS (Ocean Acoustic Waveguide Remote Sensing), it will be possible to instantaneously image areas in excess of 100 km diameter.
