Resumo(s)
Acoustic focalization is a well known concept that aims at estimating source location
through the adjustment of multiple environmental parameters. This paper uses the same
concept for inverting water column sound speed in a blind fashion, where both source
location and source emitted waveform are not known at the receiver - that is Blind Ocean
Acoustic Tomography (BOAT). The results obtained with BOAT, using ship noise data
received on a vertical line array in a shallow water area off the coast of Portugal, show
that it is indeed possible to obtain reliable joint estimates of source location and water
column sound speed. During that process, it was shown that source range and depth,
and Bartlett power, where good indicators of the degree of focus of the model being
used.
