MFP Geoacoustic Inversion of Haro Strait Array Data

Abstract

The primary long term objective of this project is to provide a rapid, real-time, efficient, wide area assessment technique to estimate full 3-D (range, depth, and azimuth) geoacoustic shallow water parameters. These parameters include geometric values such as source location, array element location (arrays can be non-linear), and water depths as well as bottom properties such as sediment layer thicknesses, sound-speeds, densities, and attenuations). This wide area assessment would be made via multiple rapidly deployed receiver arrays and multiple broadband low frequency sources. The environmental parameters could then be used as inputs to signal processing methods for the detection, localization, and identification of targets or for monitoring of the region for effects such as global warming or for the tracking of marine mammals.
