Detection Classification and Localisation of Marine Mammals Using the Passive Acoustic Capabilities of an LFAS System
conference paper
World-wide a concern is emerging about the influence of man-made sound on marine life and more particularly marine mammals, who fully depend on sound in their natural behaviour. High power active sonars systems like Low Frequency Active Sonar (LFAS) are at stake. These systems, designed for long range detection of submarines, consist of a powerful source and a towed array receiver. Incidents with marine mammals could be avoided if these receivers, dedicated to detection of submarine echoes, were also equipped with Detection, Classification and Localisation (DCL) capabilities of marine mammals. In this paper the development of a (prototype) DCL system for the TNO-FEL LFAS array (named CAPTAS) is described. The DCL algorithms are applied to simulated and sea trial data. Results are promising for detection and encouraging for classification and localisation.
