초록

영상정보용 데이터링크는 장거리의 공중-지상 환경에서 영상과 신호정보를 전송하도록 설계된 통신 시스템이다. 본 논문은 장거리 공중-지상 채널환경의 신호 분석에 적합한 곡면지구 2-Ray 모델을 사용하여 영상정보용 데이터 링크의 통신거리에 따른 수신전력 변화 폭을 분석하고 지면 반사파에 의한 수신전력의 변화폭을 경감할 수 있는 수신 안테나의 최적 고각 제어방법을 제안한다. 제안된 방법은 추가적인 하드웨어 성능 향상 없이도 기존의 고각 제어 방법에 비하여 추가적인 링크마진을 확보할 수 있다.

Common data link systems are designed to transmit the imaginary and signal intelligence data at long distance air-ground line of sight(LOS) link. In this paper, we analyze the received power variation according to the communication distance of the common data link using curved earth 2-Ray model suitable for received signal power analysis of long distance air-ground wireless channel. We propose optimal elevation angle control method of the receiving antenna to reduce a power variation caused by ground-reflected wave. Proposed method can get additional link margin compared to the conventional method without any additional hardware performance enhancement.
