Progress Report on Advanced Detection and Classification Algorithms for Acoustic-Color-Based Sonar Systems

Abstract

This report summarizes recent progress by Signal Innovations Group (SIG) in supporting the Naval Research Laboratory (NRL) on development of a new low-frequency sonar system. SIG has the tasks of developing the algorithms and transitioning them to NRL, for use in sea tests. The discussion below provides a summary of the following items: (i) a kernel-based matching pursuits classification algorithm, (ii) life-long learning, (iii) in situ learning, and (iv) a discussion of the features used within the algorithms. Items (i) and (iv) are fully transitioned to NRL, and have been employed during sea tests. Items (ii) and (iii) are currently under development by SIG, in cooperation with NRL.
