As statistical independence exists between marine mammals sound and watercraft emitted noise and
among different organism signals, the study introduces blind source separation into marine mammal signals
processing. Blind source separation with single hydrophone is a special underdetermined blind separation
problem and blind source separation based on matrix calculating is no longer suitable. The problem can be
solved by expanding channels and further study finds that second iteration of blind separation can improve the
performance. Algorithm simulation and experimental data analysis show that not only marine mammals signal
but also different organism signals can be separated by this method with single hydrophone. It is proved that
the correlation coefficient of the separated signal is obviously improved, which lays the foundation for the
feature extraction and recognition of marine mammals signal.
Key words: Blind source separation , marine mammals signal processing, maximum signal noise ratio criterion, second iteration, , ,
