Abstract:

The development of new geoacoustic inversion methods, their use in the analysis of shallow water experimental data, and evaluation of geoacoustic model and parameter uncertainties including the mapping of these uncertainties through to system performance uncertainties. Analysis of geoacoustic inversion data collected from various experiments. Of specific technical interest are 1 development of methods to track the environmental parameters using sequential filtering, 2 use of ambient noise for estimation of seafloor structure parameters, and 3 the development of new inversion methods for use into the kHz frequency regime. In an ONR Graduate Traineeship Awards we address using Random Matrix Theory in ocean acoustics.
