Featureless classification for active sonar systems

OCEANS'10 IEEE SYDNEY, 2010
Active sonar systems depend on classification algorithms to identify target echoes and suppress false alarms. Historically, classifiers use a set of empirically derived features that exhibit some statistical separation between background clutter and target echoes.

Active sonar clutter classification using higher order moments

Proceedings of Meetings on Acoustics, 2010
The statistics of normalized matched-filter echoes from an active sonar system operating in a myriad of oceanic environments has been studied extensively for three broad clutter classes including using low-order cumulants to classify subregions of the data [Gelb et al., Proceedings of the ISURC (2008) and references therein].

Object classification and acoustic imaging with active sonar

The Journal of the Acoustical Society of America, 1992
The theoretical underpinnings of underwater acoustic classification and imaging using high-frequency active sonar are studied. All essential components of practical classification systems are incorporated in a Bayesian theoretic framework. The optimum decision rules and array processing are presented and evaluated.

Active sonar classification using Bayesian decision theory

[1990] Proceedings. The Twenty-Second Southeastern Symposium on System Theory, 2002
Consideration is given to the performance analysis of optimal sonar classification. To perform active classification, a known waveform is transmitted into a medium and directed toward a region called the test volume. An array of N sensors is used to pick up the backscattered signal energy reflected from the M cells of the test volume, and the data are ...

Classification of Underwater Targets with Active Sonar

Proceedings. The First IEEE Regional Conference on Aerospace Control Systems,, 2005
This paper presents an ongoing effort in early classification of underwater targets with active sonar returns. Active sonar will play an important role in future antisubmarine warfare, especially against highly silenced targets. The emphasis of the paper is placed on various aspects and methodologies applicable to the classification problem.
