Converted measurements random matrix approach to extended target tracking using X-band marine radar data
Vivone, Gemine; Braca, Paolo; Granström, Karl; Natale, Antonio; Chanussot, Jocelyn (CMRE, 2019/06)Conventional tracking algorithms rely upon the hypothesis of one detection per target for each frame. However, very fine spatial resolution radars represent widespread systems that provide data for which this hypothesis ... -

Vivone, Gemine; Braca, Paolo; Errasti, Borja (CMRE, 2019/06)X-band marine radar systems are flexible and low-cost tools for monitoring multiple targets in a surveillance area. They are able to provide high resolution measurements in both space and time. Such features offer the ... -
Extended target tracking using joint probabilistic data association filter on X-band radar data
Vivone, Gemine; Braca, Paolo; Errasti, Borja (CMRE, 2019/06)X-band Marine radar systems are low-cost tools for monitoring multiple targets in a surveillance area. Although they may suffer from several sources of interference, high resolution measurements in both space and time can ... -
Joint probabilistic data association tracker for extended target tracking applied to X-band marine radar data
Vivone, Gemine; Braca, Paolo (CMRE, 2019/06)X-band marine radar systems are flexible and low-cost tools for monitoring multiple targets in a surveillance area. Although they may suffer from several sources of interference, e.g., sea clutter, they can provide ... -
Joint probabilistic data association tracker for extended target tracking applied to X-band marine radar data
Vivone, Gemine; Braca, Paolo (CMRE, 2017/11)X-band marine radar systems are flexible and low-cost tools for monitoring multiple targets in a surveillance area. Although they may suffer from several sources of interference, e.g., sea clutter, they can provide ... -
Knowledge-based ship tracking applied to HF surface wave radar data
Vivone, Gemine; Horstmann, Jochen; Braca, Paolo (CMRE, 2019/06)In recent years, low-power high-frequency surface-wave radars have received significant attention thanks to their over-the-horizon coverage capability and the continuous-time operation mode. These radars have become effective ... -

Maritime situational awareness use cases enabled by space-borne sensors
Millefiori, Leonardo; Vivone, Gemine; Braca, Paolo; Cazzanti, Luca; Bryan, Karna (CMRE, 2019/06)This paper discusses a technique for predicting a vessel?s position over a long time horizon with much lower uncertainty than current methods. Lowering the uncertainty of long-range prediction is a key challenge in maritime ... -
Model performance assessment for long-term vessel prediction using HFSW radar data
Vivone, Gemine; Millefiori, Leonardo; Braca, Paolo; Willett, Peter K. (CMRE, 2019/06)Vessels in open seas are seldom continuously observed. Thus, the problem of long-term vessel prediction becomes crucial. This paper focuses its attention on the performance assessment of the Ornstein- Uhlenbeck target ... -
Multiple Bayesian extended target tracking
Vivone, Gemine; Braca, Paolo; Granström, Karl; Willett, Peter K. (CMRE, 2019/06)To track an extended target presents challenges because the hypothesis of "one target means one detection" is not valid. Several approaches to extended target tracking (ETT) have been found promising, and in particular ... -
Multiple sensor Bayesian extended target tracking fusion approaches using random matrices
Vivone, Gemine; Granström, Karl; Braca, Paolo; Willett, Peter K. (CMRE, 2019/06)The tracking of extended targets is attracting a growing literature thanks to the high resolution of several modern radar systems. A fully Bayesian solution has been proposed in the random matrix framework. In this paper, ... -
Multiple sensor measurement updates for the extended target tracking random matrix model
Vivone, Gemine; Granström, Karl; Braca, Paolo; Willett, Peter K. (CMRE, 2019/06)In this paper, multiple sensor measurement update is studied for a random matrix model. Four different updates are presented and evaluated: three updates based on parametric approximations of the extended target state ... -
Performance assessment of vessel dynamic models for long-term prediction using heterogeneous data
Vivone, Gemine; Millefiori, Leonardo; Braca, Paolo (CMRE, 2019/06)Ship traffic monitoring is a foundation for many maritime security domains, and monitoring system specifications underscore the necessity to track vessels beyond territorial waters. However, vessels in open seas are seldom ... -
Realistic extended target model for track before detect in maritime surveillance
Errasti, Borja; Fuscaldo, Walter; Braca, Paolo; Vivone, Gemine (CMRE, 2019/06)Traditional target tracking algorithms are generally fed a set of thresholded detections under the hypothesis that no more than one detection is generated by each single target. Improvements in modern radar systems have ... -
