안티드론 기술의 특허동향 분석 : 무력화 수단 및 방법을 중심으로

Recently, drones have been used for a variety of purposes, as well as military use, widely distributed among the public. However, as drones are used for illegal purposes such as crime and terrorism, research on anti-dron-related technologies has been active recently. Anti-drone technology can be classified into detection, tracking, and neutralization. Among them, the neutralization technologies are distinguished by using networks to capture drones, by disturbing control frequencies or GPS signals that drones are using, and by firing guns and lasers directly into drones to destroy them. Thus, in this paper, we searched for patents applied to Korea, USA, Japan, and EUrope since 2000 for drone neutralization technology, and extracted a total of 151 valid patents. According to the analysis, the most frequently applied to the USA, the main methods of neutralizing drone are the use of capture networks and radio disturbance. The capture network mainly used defense drones and projectiles equipped with nets on the ground. And radio disturbance methods were mainly used for radio disturbance devices and portable devices(jamming guns) on the ground were used. Major applicants included Battelle Memorial Institute, XiDrone Systems, Diehl Defense, Department 13, MBDA and Openworks Engineering.
