Abstract

In this paper, we studied on-board antenna(primary link/secondary link/satellite link) used in UAV Data-link system. As a result, it is ideal to configure the Data-link as a triple link to secure the flight stability of the UAV, but the communication link should be configured according to the operating platform. As a result of overseas R&D trend analysis, the on-board Data-link antenna is installed and operated in a location where it is easy to secure LOS. The primary link consists of a directional antenna for basic operation and an omni-directional antenna for emergency operation. The secondary link uses a monopole/dipole antenna in the UHF/C band. Satellite link has been developed to apply phased array antenna to improve UAV operability.

본 논문에서는 UAV 데이터링크 시스템에 사용되는 탑재 안테나(1차링크/2차링크/위성링크)에 대해 연구하였다. 연구결과, UAV의 비행 안정성을 확보하기 위해 데이터링크는 3중링크로 구성하는 것이 이상적이나 운용 플랫폼에 맞게 통신링크를 구성해야 한다. 해외 연구개발 동향 분석결과, 탑재 데이터링크 안테나는 LOS 확보가 용이한 위치에 장착되어 운용되고 있다. 1차링크는 기본운용을 위한 지향성 안테나, 비상운용을 위한 무지향성 안테나로 구성하며, 2차링크는 UHF/C 대역에서 모노폴/다이폴 구조의 안테나를 사용한다. 위성링크는 UAV의 운용성 향상을 위해 위상배열안테나를 적용하는 추세로 발전하고 있다.
