Abstract

Airborne SAR system is the imaging Radar system that is loaded on a manned or unmanned aircraft, which is in charge of high quality image acquisition and moving target detection. This paper describes the operational requirements for the Airborne SAR system and suggests the operational concept to satisfy the requirements. To be specific, it describes the interface with airborne system, state definition and transition, operation mode based on mission definition file, fault management, and data storing and transmission concept. Finally, it gives the ground test results to verify the SAR system operational concept.

항공탑재 SAR 시스템은 유/무인 항공기에 탑재되어 고해상 영상정보 수집과 지상 이동 표적 탐지의 임무를 담당하는 영상 레이더 시스템으로, 선진국을 중심으로 운용되고 있으며 국내에서도 현재 개발이 진행 중에 있다. 본 논문에서는 항공탑재 SAR 시스템 운용을 위한 운용요구조건 및 운용 요구조건을 만족하기 위한 다중모드 및 실시간 SAR 시스템 운용개념에 대하여 기술한다. 항공 시스템과의 연동개념, 시스템 상태정의 및 천이개념, 임무정의파일 기반 임무수행 개념, 고장진단 및 관리개념, 촬영자료 저장 및 전송 개념에 대해 설명하고, 지상검증시험을 통한 SAR 시스템 운용개념 검증 결과에 대해 기술한다.
