Bayesian track-to-graph association for maritime traffic monitoring
Grasso, Raffaele; Millefiori, Leonardo; Braca, Paolo (CMRE, 2019/05)We present a hypothesis test to associate ship track measurements to an edge of a given graph that statistically models common traffic routes in a given area of interest. The association algorithm is based on the hypothesis ... -
Distributed underwater glider network with consensus Kalman filter for environmental field estimation
Grasso, Raffaele; Braca, Paolo; Fortunati, Stefano; Gini, Fulvio; Greco, Maria S. (CMRE, 2019/06)A distributed coordinated dynamic sensor network for optimal environmental field estimation is proposed and tested on simulated and real data. The architecture is used to distribute the estimation of 3D timevarying fields ... -
Dynamic underwater glider for environmental field estimation
Grasso, Raffaele; Braca, Paolo; Fortunati, Stefano; Gini, Fulvio; Greco, Maria S. (CMRE, 2019/06)A coordinated dynamic sensor network of autonomous underwater gliders to estimate three-dimensional time-varying environmental fields is proposed and tested. Integration with a network of surface relay nodes and asynchronous ... -
Dynamic underwater sensor network for sparse field estimation
Grasso, Raffaele; Braca, Paolo; Fortunati, Stefano; Gini, Fulvio; Greco, Maria S. (CMRE, 2019/06)A coordinated dynamic network of autonomous underwater gliders to estimate 3D environmental sparse fields is proposed and tested. Field spatial sparsity is exploited in the estimation algorithm. Moreover field measurements ... -
Environmental field estimation by consensus based dynamic sensor networks and underwater gliders
Grasso, Raffaele; Braca, Paolo; Fortunati, Stefano; Gini, Fulvio; Greco, Maria S. (CMRE, 2019/06)A coordinated dynamic sensor network of autonomous underwater gliders to estimate 3D time-varying environmental fields is proposed and tested. Each sensor performs local Kalman filter sequential field estimation. A network ... -
Geo-spatial tactical decision aid systems: fuzzy logic for supporting decision making
Grasso, Raffaele; Giannecchini, Simone (NURC, 2006/08)Tactical decision aid systems support -
The impact of sea state on HF surface-wave radar ship detection and tracking performances
Maresca, Salvatore; Braca, Paolo; Grasso, Raffaele; Horstmann, Jochen (CMRE, 2019/06)Nowadays, we face an ever increasing interest in new technologies and solutions for the maritime surveillance (MS) domain. In such a context, oceanographic high-frequency surface-wave (HFSW) radars have started to get ... -
Maritime surveillance using multiple high-frequency surface-wave radars
Maresca, Salvatore; Braca, Paolo; Horstmann, Jochen; Grasso, Raffaele (CMRE, 2014/05)In the last decades, great interest has been directed toward low-power high-frequency (HF) surface-wave radars as long-range early warning tools in maritime-situational-awareness applications. These sensors, developed for ... -
Maritime surveillance with multiple over-the-horizon HFSW radars: an overview of recent experimentation
Braca, Paolo; Maresca, Salvatore; Grasso, Raffaele; Bryan, Karna; Horstmann, Jochen (CMRE, 2019/06)This paper briefly explores the high-frequency surface-wave (HFSW) radar technology in general, and Wellen radar (WERA) in more detail. Then it describes the multitarget tracking data fusion (MTTDF) network architecture ...
