Abstract

This paper designs and presents the results of an air network simulation radio transmission link applied with a multi-beam active phase array antenna simulator in a testbed system for verifying an air network currently underway as a technology development task. Using the Ku band, the Radio transmission link was designed in consideration of the link budget to satisfy the requirements for the system being developed. Considering short-distance links and long-distance links, the required EIRP and G/T performance scales of multi-beam repeaters and mission planes were applied to confirm the minimum and maximum link margins based on Eb/No. In this Radio Transmission Link design, the application analysis results such as rainfall availability are used to effectively establish standards when selecting the operating radius of the multi-beam relay system and related system standards.

본 논문에서는 현재 기술 개발 과제로 진행 중인 공중 네트워크 검증용 테스트베드 시스템에 다중빔 능동위상배열 안테나 모의기 적용 공중 네트워크 모사 Radio 전송링크를 설계하여 그 결과를 제시한다. Ku 대역을 활용하여 개발 중인 시스템에 대한 요구사항을 만족하도록 링크 버짓을 고려하여 Radio 전송링크를 설계하였다. 단거리 링크와 장거리 링크를 고려하여 요구되는 다중빔 중계기와 임무기의 EIRP 및 G/T 성능 규모를 적용하여 Eb/No를 기준으로 최소, 최대치 링크 마진을 확인하였다. 이러한 Radio 전송링크 설계에서 강우 가용도 등 적용 분석 결과를 이용하여 다중빔 중계시스템 적용 공중 중계 운용 반경 및 관련 시스템 규격 선정시 기준 수립에 효과적으로 활용될 수 있도록 기여하고자 한다.
