• Abstract:
  Passive underwater acoustic sensing technologies applied to mobile autonomous maritime systems allow for minimum environmental impact, covertness, long endurance, wide area coverage, near real-time, continuous (‘24/7’) monitoring, and the availability of several capabilities, ranging from detection to the classification of acoustic noise sources. Gliders – both as unmanned underwater and unmanned (sea) surface platforms – are particularly appropriate for this kind of application, as their features include persistence, discreteness, portability, scalability and remote control. In the context of the European Union’s Seventh Framework (FP7) project PERSEUS, NATO STO CMRE developed a cutting-edge low-power passive acoustic system to be hosted on persistent platforms such as underwater gliders and wave gliders. The system is able to detect, track and classify surface vessels by using a compact volumetric array of hydrophones and processing acoustic data in real time, directly on board the gliders, through the application of advanced algorithms. During the project at-sea demonstrations (2014-2015) results were communicated to the PERSEUS command and control (C2) station for data fusion and visualization. In post-analysis the signal processing chain has been recently extended to the capability of tracking multiple vessels at the same time, by means of a Bayesian propagation approach.
