Abstract:
This work presents a theoretical study of the passive detection of an acoustic target in a shipping
noise induced field. Optimal and sub-optimal detectors are derived for deterministic and random assumed
propagation channels. Their performance is analytically derived and compared. The various detectors are
then tested on a realistic shipping noise distribution obtained from AIS data recorded off the west coast
of Portugal during August 2014 for various target ranges, depths and frequency spectra. This study is a
preparatory work for the development of a set of acoustic surveillance buoys to be deployed during 2017
offshore the west coast of Portugal under project SUBECO. First test at sea is now scheduled for April 2017.
