Abstract

A key difference between a tactical military and commercial satcom system is that the military system is expected to provide a service in the presence of ECM threats such as jamming. In this paper, we analyzed the three different type of link system applicable to the military satellite and directly compared to each system in order to find system performance according to the maximum jammer power. For the analysis, we modeled and simulated the SHF satellite system based on uplink jamming. From the results, it is found for each different type of link the maximum jammer power that can be tolerated with link operating at its suggested nominal rate. Also, we studied to the survivability level against the jamming condition through the performance comparison in shipborne and portable terminal consistent with frequency.

상용위성통신의 경우 일반 광역 통신지원은 가능하지만 전시/유사시의 생존성과 보안성을 요하는 환경에서는 사용이 크게 제한되는 단점이 있다. 따라서, 본 논문은 군 위성시스템에 적용 가능한 세 가지 형태의 중계시스템을 제안하고 분석했으며, 상향링크 방해시의 지원 가능한 데이터율을 기준으로 성능을 분석/비교하여 군 운용환경에 따른 위성자원의 이용효율을 높이는 방안을 모색하였다. 이를 이해 중계기와 함정용 단말의 설계변수를 설정하여 적용하였으며, 또한, 각 대역별(UHF/SHF/EHF) 항방해 성능비교를 통하여 운용환경에 따른 생존성의 정도를 파악하였다.
