드론을 이용한 항행안전시설 전파왜곡 분석 = Analysis of Radio Distortion in Navigational Aid using Drone

다국어 초록 (Multilingual Abstract)

To overcome the limitation of ground inspection for Navigational Aid, Korea Airport Corporation (KAC) developed a drone system for Navigational Aid inspection. This drone system has the advantage that they can inspect the air radio signal at the perspective of user (aircraft). Since drones have more free flight paths and easier control of flight speeds compared to aircrafts, drones can check sections of suspected airborne radio wave distortions at desired paths and speeds. Recently, with the acceleration of the development around the airport, there is a concern about the deterioration of the quality of radio signal of Navigational Aid. In order to analyze radio distortion of Navigational Aid, a radio wave environmental survey was conducted using drones. When the signal received by each flight path of the drone was measured, the origin of the reflected wave was identified by analyzing the section in which the radio signal was distorted.

기존 항행안전시설 지상점검의 한계점을 극복하기 위해서 한국공항공사는 항행안전시설 점검용 드론시스템을 개발하였다. 드론시스템을 이용한 항행안전시설 점검은 사용자(항공기) 입장에서 공중 전파신호를 점검할 수 있다 장점이 있다. 또한 드론은 항공기와 비교하여 비행경로가 자유롭고 비행속도의 제어가 용이하기 때문에 공중 전파신호를 보다 면밀히 점검할 수 있다. 최근 공항주변 개발의 가속화에 따라 항행안전시설 전파신호의 품질저하에 대한 우려가 고조되고 있다. 이에 따라, 항행안전시설 전파왜곡현상을 분석하기 위해 드론을 활용한 전파환경조사를 진행하였다. 드론의 비행경로별 신호수신 시 항행전파신호가 왜곡되는 구간을 측정·분석하여 반사파가 발생되는 원점을 특정화하였다.
