| dc.description.abstract | A passive acoustic analysis of data recorded during the SACLANTCEN | |
| dc.description.abstract | SWAC4 sea-trial in Kyparissiakos Gulf during May 1996 was performed | |
| dc.description.abstract | with the specific objectives of detecting, localizing, and classifying marine mammal sounds. Detection and localization (bearing only) was performed using a passive sonar system in a playback mode and by an automatic detection algorithm for specific runs or run segments. The results of the automatic | |
| dc.description.abstract | detection processing allow association over time and bearing, creating 'events' that may then be classified by experts. This memorandum describes the preprocessing of the SWAC4 sea-trial data and the algorithm used to perform the automatic detection processing. The results of the automatic detection processing are then displayed in time-beam number plots and used to perform rough localization of detected events through triangulation. | |
