Multisensor system for the protection of a critical harbour infrastructure

The critical facilities within a harbour area require special protection, including security systems capable of monitoring both surface and underwater areas. The paper presents the concept of a multisensor security system for harbour protection, capable of complex monitoring of selected critical resources. The proposed system consists of a command centre and several different sensors deployed in key areas, providing effective protection from penetration from land and sea, with special attention focused on the monitoring of the underwater zone. The initial project of such systems was presented, its configuration and initial tests of the selected components. The protection of a surface area is based on medium-range radar, LLTV, and infrared cameras. The protection of an underwater zone is based on sonar, acoustic, and magnetic barriers. Both systems are combined into one, integrated multisensor monitoring system. Some results of theoretical analyses based on the detection of a fast and small surface were presented.
