GEM elettronica has realized a wide number of maritime surveillance projects specifically conceived for the security of offshore platforms. These installations can ensure the protection of drilling and extraction sites located in the high sea by the utilization of radar and cameras able to automatically detect and and locate surface objects, on a wide area, by means of automatic sensors data processing. The proposed equipment are designed with state of the art technologies, well proven on the field, for critical surveillance applications.
The mission of the proposed system is to detect as soon as possible all vessels entering the covered area.
The basic principle of operation is that the radar, in a track-while-scan mode and having typically a longer range than camera equipment, performs the first detection of surface objects entering the covered area.
On operator command, the object coordinates are transferred automatically from the radar processor to the video processor to aim the turret and its cameras on the target of interest (designation mode), in order to get the video image of the object. The system permits detection, recognition and identification of friend and hostile vessels.
The operator can then decide further to activate the automatic video tracking functionality, that identifies the object contours in the field of view, and performs turret position corrections to keep the object image in the center of the screen, even in case of vessel movement, for continuous monitoring.
