MAST Asia 2017: NEC introduces second-generation underwater invasion warning system

12 June 2017

NEC Corporation has developed an improved variant of its sonar-based underwater invasion warning system (UIWS).

Speaking at the MAST Asia 2017 exhibition in Tokyo, Makoto Ogawa, a member of the corporation's Radio Application Division, said that the new model will provide a more reliable deterrent against underwater threats posed to critical infrastructure in coastal areas.

"[Strategic] targets such as oil rigs, ports, power plants, or harbours are exposed to often neglected underwater threats. The [second-generation] UIWS aims to mitigate those threats by detecting their reflected acoustic signal.

"Defending coastal facilities with the sole use of radars or cameras generates a security hole, because radio and light waves do not perform well under water," said Ogawa.
