Abstract

Synthetic Aperture Radars (SARs) that can be performed regardless of weather and day-and-night conditions have been developed for Earth remote sensing in recent decades. Korea Aerospace Research Institute (KARI) has developed and launched successfully the KOrea Multi-Purpose SATellit-5 (KOMPSAT-5) which is the first Korean SAR satellite in 2013, and is currently developing the KOMPSAT-6 which is the next generation series of the SAR satellite. This paper describes the development of the system performance analysis simulator which is necessary for spaceborne SAR payload design and analysis. The system performance analysis simulator consists of the antenna pattern generation simulator, the SAR performance analysis simulator, and the image quality analysis simulator. The simulation results of this research show that this simulator can be applicable as the design and analysis tool for the spaceborne SAR payload system during the design phase.

최근 날씨와 주야 조건에 상관없이 지구 관측을 수행할 수 있는 영상레이더 탑재체가 활발하게 연구되고 있다. 한국항공우주연구원은 2013년 한국 최초의 영상레이더 위성인 다목적실용위성5호를 성공적으로 개발 및 발사하였으며 현재 영상레이더 차세대 시리즈 위성인 다목적실용위성6호를 개발하고 있다. 본 논문은 영상레이더 탑재체의 설계와 분석을 위하여 필수적인 영상레이더 탑재체 시스템 성능 분석 시뮬레이터의 개발에 관한 것이다. 시스템 성능 분석 시뮬레이터는 안테나 패턴 생성 시뮬레이터와 시스템 성능 분석 시뮬레이터, 그리고 영상 품질 분석 시뮬레이터로 이루어진다. 영상레이더시스템 성능 분석 시뮬레이터의 시뮬레이션 결과로부터 영상레이더 설계 단계에서 위성용 영상레이더 탑재체의 설계 및 분석 툴로써 적용 가능할 것으로 기대한다.
