Cooperative robotic networks for underwater surveillance: an overview
(CMRE, 2019/06)
Underwater surveillance has traditionally been carried out by means of surface and undersea manned vessels equipped with advanced sensor systems. This approach is often costly and manpower intensive. Marine robotics is an ...
Multiple Bayesian extended target tracking
(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 ...
Online estimation of unknown parameters in multisensor-multitarget tracking: a belief propagation approach
(CMRE, 2019/05)
We propose a Bayesian multisensor-multitarget tracking framework, which adapts to randomly changing conditions by continually estimating unknown model parameters along with the target states. The time-evolution of the model ...
Anomaly detection and tracking based on mean-reverting processes with unknown parameters
(CMRE, 2019/05)
Piecewise mean-reverting stochastic processes have been recently proposed and validated as an effective model for long-term object prediction. In this paper, we exploit the Ornstein-Uhlenbeck (OU) dynamic model to represent ...
Consistent estimation of randomly sampled Ornstein-Uhlenbeck process long-run mean for long-term target state prediction
(CMRE, 2019/06)
In this letter, we study the problem of estimating the long-run mean of the Ornstein-Uhlenbeck (OU) stochastic process and its effect on the long-term prediction of future vessel states, which is a crucial problem for ...
Tracking an unknown number of targets using multiple sensors: a belief propagation method
(CMRE, 2019/06)
We propose a multisensor method for tracking an unknown number of targets. Low computational complexity and very good scalability in the number of targets, number of sensors, and number of measurements per sensor are ...
The impact of sea state on HF surface-wave radar ship detection and tracking performances
(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 ...
Realistic extended target model for track before detect in maritime surveillance
(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 ...
Distributed underwater glider network with consensus Kalman filter for environmental field estimation
(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 ...
Modeling vessel kinematics using a stochastic mean-reverting process for a long-term prediction
(CMRE, 2019/06)
We present a novel method for predicting long-term target states based on mean-reverting stochastic processes. We use the Ornstein-Uhlenbeck (OU) process, leading to a revised target state equation and to a time scaling ...
