Full Field 3-D Geoacoustic Inversion
Abstract
The full field 3-D geoacoustic inversion method is eventually intended for real-time estimation of range, depth, and azimuthally varying shallow water environmental properties by non-invasive, acoustic, remote sensing means via simple broadband sources such as SUS. The estimated environmental properties would then be available as input parameters to fleet acoustic propagation models used for the detection of targets, e.g., subs or mines. The objective of this approach is to estimate those geoacoustic environmental parameters to which acoustic fields are sensitive. Such environmental parameters include: number of sediment layers, sediment thicknesses, attenuations, densities, and sound-speed profiles. The intention is to replace present requirements for extensive environmental sampling (which can be extremely time-consuming and expensive) with intense computational processing of array data (with limitations determined primarily by the nature of the array configuration and the computer system available for data processing).
