Joint probabilistic data association tracker for extended target tracking applied to X-band marine radar data
(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 ...
High-resolution beamforming techniques performance analysis
(NATO. SACLANTCEN, 1986/11)
Seven different beamforming techniques (including both conventional and high-resolution types) have been analyzed and compared in order to develop a quantitative relationship between resolution performance on the one hand ...
Autonomous networked anti-submarine warfare research and development at CMRE
(CMRE, 2019/06)
CMRE has been evaluating the potential of autonomous networked ASW using underwater vehicles through a program of sonar signal processing, underwater communications, navigation and robotic behavior developments and at-sea ...
Detection models and target information processing
(NATO. SACLANTCEN, 1982/06)
The passive sonar equation leads in a natural manner to sensor detection performance contours. Useful information can be extracted from observed fractional holding time on non-cooperative targets by use of these contours. ...
A scalable algorithm for tracking an unknown number of targets using multiple sensors
(CMRE, 2019/06)
We propose an algorithm for tracking an unknown number of targets based on measurements provided by multiple sensors. Our algorithm achieves low computational complexity and excellent scalability by running belief propagation ...
Long-term vessel kinematics prediction exploiting mean-reverting processes
(CMRE, 2019/06)
Long-term target state estimation of non-manoeuvring targets, such as vessels under way in open sea, is crucial for maritime security. The dynamics of non-manoeuvring targets is traditionally modelled with a white noise ...
Realistic ship model for extended target tracking algorithms
(CMRE, 2019/06)
Recent developments in high resolution sensors have encouraged the use of Extended Target Tracking (ETT) algorithms specifically designed to deal with targets that generate more than one detection per frame. At the same ...
Converted measurements Bayesian extended target tracking applied to X-band marine radar data
(CMRE, 2019/06)
X-band marine radar systems are flexible and low-cost tools for monitoring multiple targets in a surveillance area. They can provide high resolution measurements both in space and time. Such features offer the opportunity ...
Maritime surveillance using multiple high-frequency surface-wave radars
(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 ...
Belief propagation based AIS/radar data fusion for multi-target tracking
(CMRE, 2019/05)
A data fusion technique aiming at combining observations from two classes of sensors is proposed. The first class consists of sensors that produce periodic noisy observations of the targets; moreover, they may also miss ...
