South Korean research team has had success creating a new device that can identify and monitor drones operating illegally, which can lead to crimes including terrorism, privacy invasion, and unlawful flight. It is anticipated that this technology would improve public safety and fortify national security against the threat posed by illicit drones.
An EO/IR (Electro-Optics/Infrared) connected radar system has been developed by the Electronics and Telecommunications Research Institute (ETRI) to detect and track illegal drones. The technology has been successfully transferred to Samjung Solution Co., Ltd. by the institute, and field deployment is now imminent.
By automatically guiding EO/IR sensors toward the target that the radar has detected, ETRI’s EO/IR-linked radar technology for illegal drone detection and tracking is able to identify, track, and detect incoming drones. Radar and EO/IR subsystems form the foundation of the system.
ETRI and Hanwha Systems Co., Ltd. collaborated to create the radar subsystem, which uses the Ku band instead of the X band, which is frequently utilized for military applications, to identify small drones within a 5-kilometer radius.
ETRI independently designed the EO/IR subsystem. The drone is detected, tracked, and identified by this subsystem after it gets target information from the radar and records video footage of the target using an EO/IR camera. When a flying item approaches within 2 km, the EO/IR subsystem can identify whether it is a drone. It can also detect and track targets up to 3 km away.
In the meantime, Samjung Solution Co., Ltd. received this technology from ETRI in 2022. Then, as part of the Police Technology Commercialization Project, which was headed by the Korean National Police Agency and the Ministry of Science and ICT, Samjung Solution brought the technology to market through the Short-Term Security R&D Technology Commercialization Project, which took place between April 2022 and March 2024.
Samjung Solution created an integrated solution for low-altitude unmanned aerial vehicles as part of this project, and on July 18, they successfully registered their “Vehicle-type Integrated Solution System” in the Public Procurement Service’s Nara Marketplace.
This technology was employed by ETRI for an unauthorized drone response exercise at the 2024 Ulchi Training. The research team was able to remotely identify and monitor a drone that was trying to enter ETRI offices on August 20. They verified the drone’s existence once it was within visual range and jammed its transmissions to successfully deactivate it.
The effectiveness of illegal drone monitoring and detection technology using ETRI’s EO/IR-linked radar system in the real world was validated by this training. ETRI is anticipated to become a leader in security and military technology and boost national security by ensuring the public’s and the country’s safety via the effective development of this technology.
Cha Ji-Hun, Director of ETRI’s Autonomous UAV Research Section, stated, “Our EO/IR-linked radar system for illegal drone detection and tracking is an advanced technology that can respond quickly and accurately to external threats posed by illegal drones. This new technology is expected to play a pivotal role in enhancing national security and public safety. ETRI will continue to devote its efforts to developing innovative solutions that contribute to national security and public safety.”
The project’s researchers anticipate that this technology will be applied in a number of areas, including VIP protection, border patrol, coastline monitoring, drone traffic control, UTM-based facilities, monitoring and surveillance for illegal drones at major events, public facilities, sports arenas, and more.
