A Study of the Uncertainty in Estimate Seabed Properties as a Result of Geoacoustic Inversion Algorithms
Abstract
In the littoral environment, geoacoustic properties of the seafloor can have a significant influence on acoustic propagation. Much effort has been devoted to the estimation of seafloor properties. Geoacoustic inversion techniques can provide accurate estimates of the environmental properties for most littoral environments. The disadvantage is that these methods often require many assumptions to be made in order to make the problem tractable. These assumptions include the description of the environmental model, water column properties, experimental geometry, range-dependence, etc. Another thing that is taken for granted is that the algorithm used will provide the correct answer. Geoacoustic inversion is a very difficult, multi-dimensional, non-linear optimization problem and the algorithms used often have limitations.
