A major difficulty in tracking unidentified vessels at sea is due to the need to observe large areas for long periods of time for sparsely appearing targets. A possible solution is to use a network of energy efficient underwater gliders that use buoyancy engines and are equipped with sensor array, processing, and communication hardware. Gliders, however, have a limited size and payload which limits...
Combining measurements from different types of sensors has the potential to improve tracking performance. This is attributed to the diversity of information provided by the sensors on the state of the targets. Moreover, compressively acquiring measurements has the potential to enable the collection of measurements from high resolution sensors at low sampling rates. This can further improve tracking...
