On adaptive underwater object detection
(NURC, 2012/04)
A new algorithm for the detection of underwater objects in sonar imagery is proposed. One particularly novel component of the algorithm also detects the presence of, and estimates the orientation of, sand ripples. The ...
Underwater source localization using a hydrophone-equipped glider
(CMRE, 2014/01)
Buoyancy-driven underwater gliders are autonomous underwater vehicles that were originally developed to collect oceanographic data. CMRE is studying the use of this technology for the characterization of denied areas, ...
Range estimation of cetaceans with compact volumetric arrays
(CMRE, 2014/01)
Passive acoustic monitoring is the method of choice to detect whales and dolphins that are acoustically active and to monitor their underwater behaviour. The NATO Science and Technology Organization Centre for Maritime ...
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 ...
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 ...
Counter piracy surveillance requirements for early detection, military rescue, or evasion
(NURC, 2012/06)
Best practice for protection against pirates includes coordination with the military forces operating in the area, constant watch against the approach of pirates, and measures to prevent or delay their boarding. The time ...
Detection, tracking and fusion of multiple HFSW radars for ship traffic surveillance: experimental performance assessment
(CMRE, 2014/05)
Low-power HF surface-wave radars fit well the role of long-range early-warning tools in maritime situational awareness applications, by virtue of their over-the-horizon coverage capability and continuoustime mode of ...
