Uniqueness problems in extracting environmental parameters from high-frequency shallow-water reverberation measurements
Inversion techniques that extract environmental parameters from measured reverberation often lead to mathematical problems that are not well-posed. Two examples illustrate this possibility. The first hows how a model can produce accurate fonvard predictions though based on erroneous physical assumptions. The second example involves measured torpedo data, and offers some guidance to resolving ambiguities that are due to abrupt changes in the bottom sediment.
