Description
Summary:This paper presents the design and preliminary implementation of a computer module for the automatic detection and identification of broadband transient signals emitted by marine mammals generically referred to as clicks. This module will make part of a more wide system designed for detecting and identifying the whole range of signals emitted by marine mammals. The computer module has been extensively tested with simulated signals incorporating the basic structure of sperm whale clicks and with real signals covering a broad spectrum of situations encountered at sea as this corresponding to the presence of high level interfering noise and cluttering of signals.
