Abstract

Since concentration of greenhouse gas increases continuously from human's fossil fuel use, urbanization, and cultivation, it is trend that climate change is appearing. In Addition, in 20th century, occurrence of disaster is accidental and huge, and damage level also increases gradually. Therefore, in order to preserve the territory and to protect people's life and property against new type disasters, disaster detection satellite (payloads) development is required urgently. In this paper, we conduct a research and development for the prompt preemptive action when occurred a disaster, in particularly, about the disaster observation optimized at Korea's geographical features for the irregular future disasters. For the payload design which is specialized detect disasters, we create a tech tree of satellite imagery applications based 10 disaster types, and analyze the satellite sensor technologies referred to Landsat-8, Worldview-3 and ALOS-2.

인간의 화석연료 사용, 도시화, 경작 등으로 인해 온실가스의 농도는 계속 증가하여 기후변화가 나타나고 있는 추세이다. 이로 인해 20세기는 재난의 발생이 돌발적이고 대형화되고 있으며, 피해 규모 역시 점차 증가하는 실정이다. 따라서 과거와 다른 양상의 신종 재난에 대해 국토를 보존하고 국민의 생명과 재산을 보호하기 위해서는 재난탐지위성(탑재체) 개발이 시급히 요구된다. 본 논문에서는 불규칙한 미래재난에 대해 광역적이고, 한국지형에 최적화된 재난 관측과 재난발생 시 신속한 선제 대응을 위한 기술개발 연구를 수행하고자 한다. 이를 위해 재난 탐지 특화 탑재체 설계를 위해 10개의 재난 유형별 위성영상 활용 사례를 바탕으로 테크트리를 작성하고 국외의 유사 활용위성센서인 Landsat-8, Worldview-3, ALOS-2를 참고하여 재난탐지에 최적화된 위성 센서 기술요구조건을 분석하였다.
