We present a technique for simultaneous detection, path tracking and accurate 3D underwater localization using wideband arrays of complex geometry based on acoustic reflections clustering.

Abstract

We present a technique for simultaneous detection, path tracking and accurate 3D underwater localization using wideband arrays of complex geometry based on acoustic reflections clustering. We have extended our previously proposed algorithm for 3D localization designed for arrays that do not meet typical constraints of one half-wavelength spacing between the closest array elements. Inspired by the scope of SYMBIOSIS, a hybrid opto-acoustic system for pelagic fish species monitoring, we added more functionalities that fit the needs of the project. The proposed algorithm can automatically discriminate moving targets from stationary environmental features and track them to estimate their possible time of arrival to the system. We test the algorithm in several autonomous deployments including shallow and deep water. The experimental results for marine fauna monitoring have shown a good performance in various environments.
