Industries using small unmanned aerial vehicles called drones (hereinafter referred to as 'drones') and related technologies are rapidly developing around the world.

As drones are attracting attention as a new growth industry, their value and utility are increasing. In particular, the illegal use of drones, such as terrorism, and side effects such as collisions with manned aircraft caused by drones flying near airports are becoming very serious.

In order to solve this problem, a technology related to an anti-drone that prevents crimes or accidents caused by drones by detecting and neutralizing drones in advance has been proposed.

Anti-drone technologies that are being proposed include 'Drone Defender' that targets the drone with a scope and shoots radio waves to disable the drone's command system, 'Capture drone' that fires a net to capture the drone, and when the drone is detected by the radar A representative example is 'Drone Killer', which blows up drones by directly hitting them.

Recently, as the drone market grows, high-performance anti-drone technology that combines various technologies that provide various functions is being developed.

In particular, a radar that checks the approach of a drone and distinguishes it from a non-aggressive flying object such as a bird, a camera that identifies the type of drone and whether it is equipped with a weapon when the approach is confirmed, and transmits jammers to the drone where hostility is confirmed.
