Maritime Border Security Systems Technology
Acoustic sensors can provide effective detection in the challenging environments of maritime borders. S3 is experienced in the installation of fiber optic cable systems for use either as Distributed Acoustic Sensors (DAS) or as data links for multiple fixed sensors.
The DAS Technology
Distributed Acoustic Sensing (DAS) systems use optical fiber cables to provide distributed strain sensing. In DAS systems, the optical fiber cable itself becomes the sensing element. A DAS system allows acoustic frequency strain signals to be detected over long distances and in harsh environments. The maximum range of DAS sensitivity is typically 40-50 km, making them especially suitable for intrusion detection systems. S3 has installed DAS systems for both marine and terrestrial applications.
DAS Technology In Action
S3 has installed DAS systems for a variety of intrusion detection systems, including critical infrastructure protection and buried line sensors. The image shows a DAS system being installed on the cooling water intake of a nuclear power plant.
