At the end of last year, when it was confirmed that North Korean drones were flying around our skies, the government announced that it would come up with countermeasures.

In the midst of this, domestic researchers have developed a technology that can only capture opponent drones in urban areas without any other damage.



Reporter Jeong Gu-hee will explain the details.



<Reporter> This



is a video released by the Ministry of Defense of Russia.



The drone finds a vehicle of the Ukrainian army, and soon the self-destruct drone rushes in and explodes.



Ukrainian forces are also fighting back.



The eyes of soldiers using mortars are reconnaissance drones.



The Russian side even mobilized a gun that catches drones.



But drone defense isn't easy in practice.



Interceptor missiles are at least effective, but they are more expensive than drones, so blocking them is more damaging.



Technology is under development to disable drones using powerful broadband electromagnetic waves, but it can damage other equipment and even friendly drones.



The KAIST research team has developed a technology that uses electromagnetic waves but does not damage other electronic equipment and selectively subdues specific drones.



First, it is necessary to collect electronic information about the attitude control equipment of individual drones.



It shoots down specific electromagnetic waves that incapacitate the equipment of the targeted drone with a narrow band of frequencies.



[Kim Yong-dae/Professor of Electrical and Electronic Engineering at KAIST: When there are 100 drones from manufacturer A and 100 drones from manufacturer B, when two are flying at the same time, only drone A can fall.



] Experiments are needed to increase the electromagnetic wave output and increase the range.



Regarding North Korean unmanned aerial vehicles or drones, the research team explained that it is necessary to first secure the aircraft and collect electronic information in order to determine whether the technology will be applied.
