Anti-drone systems are mostly used to detect drones and neutralize them before aerial vehicles reach the country's key facilities. According to South Korea's Joint Chiefs of Staff (JCS), five North Korean drones flew into in South's airspace in December 2022. Although one of them entered the capital city, the South Korean military failed to identify the incursion, allowing it to safely return home up north over the demilitarized zone (DMZ).
Normally, anti-drone systems use one of two drone-attacking styles -- the "hard-kill" style which uses ammunition and missiles to physically destroy or shoot down unmanned aerial vehicles, or the "soft-kill" style which uses radio waves to jam the communication capability of drones or damage the circuit to make an emergency landing or crash into the ground. Other styles incorporate net guns and drone-hunter drones.
The Defense Acquisition Program Administration (DAPA) said that the agency will look for a bidder who would develop and set up an anti-drone system in important facilities such as naval bases, air force runways, and army bases.
According to DAPA, the to-be-adopted system would be a soft-kill style aerial defense system that is capable of detecting and recognizing small-sized drones and incapacitating them using jamming technology.
