The South Korea Defense Science Research Institute (ADD in Korean) has developed a submarine detection device and underwater acoustic sensor technologies for unmanned submersibles.
This technology is one of the core technologies applied to the unmanned submersible system that can perform underwater surveillance and reconnaissance and anti-submarine warfare missions for threat dynamics such as enemy submarines, the AAD said in a release.
The passive underwater acoustic sensor was developed over a five -year period from 2017 to 2022 to enable optimized anti-submarine detection in consideration of the operational concept and platform limitations of the unmanned submersible.
An active acoustic sensor is a sensor that transmits sound waves to detect underwater targets. Compared to existing sensors. While it is compact and lightweight, it is possible to transmit high-output broadband sound with low power.

A passive acoustic sensor is a receiving sensor that receives the target echo of the transmitted sound wave and the noise of the target itself. It has low-noise, high-sensitivity reception performance and can be arranged in a large area to improve detection performance.
ADD has secured anti-submarine detection stations for unmanned submersibles and related source technologies by performing the entire process of sensor design, manufacturing, testing and verification with its own domestic technology.
The underwater acoustic sensor technology for unmanned submersible anti-submarine detection sonar can be applied for reconnaissance in the future, and is expected to greatly contribute to the improvement of military combat power.
