Abstract

Recently, as unmanned aerial vehicle technology such as drones has developed, there are many environmental, social and economic benefits, but if there is malicious intent against important national facilities such as airports, public institutions, power plants, and the military, it can seriously affect national safety and people's lives. It can cause damage. To respond to these drone threats, attempts are being made to introduce detection equipment such as RF scanners. In particular, power transmission towers installed in substations, power plants, and Korea's power system can affect detection performance if the transmission tower is located in the RF scanner detection path. In the experiment, a commercial drone was used to measure the signal intensity emitted from the drone and confirm the attenuation rate. The average and maximum attenuation rates showed similar trends in the 2.4 GHz and 5.8 GHz bands, and were also affected by the density of the structure.

최근 드론과 같은 무인비행장치 기술이 발전함에 따라 환경적, 사회적 및 경제적으로 많은 이점이 있지만, 공항, 공공기관, 발전소, 군 등 국가중요시설에 악의적인 의도를 가질 경우 국가 안전과 국민 생활에 심각한 피해를 줄 수 있다. 이러한 드론의 위협에 대응하기 위해 RF스캐너와 같은 탐지 장비 도입을 시도하고 있다. 특히 변전소, 발전소, 우리나라 전력 계통에 의해 설치된 전력 전송용 송전탑은 RF스캐너 탐지 경로에 송전탑이 위치하면 탐지 성능에 영향을 줄 수 있다. 실험은 상용 드론을 이용하여 드론에서 방사되는 신호 세기 측정하여 감쇠율을 확인하였다. 평균 감쇠율과 최대 감쇠율은 2.4 GHz와 5.8 GHz 대역에서 유사한 경향을 보였고, 구조물의 밀도에도 영향을 받는 것을 알 수 있다.
