Abstract

In this research, we describe recent technologies and system requirements of the passive microwave radiometer used in Earth observation satellites. And we classify types of microwave radiometer system for Earth observation satellites according to observation targets and ways to scan and discuss a design method. Also, requirements of passive radiometer for Earth observation missions in the latest practical examples used and developed are analyzed in this research.

본 연구에서는 지구 관측 위성에서 사용되는 수동형 마이크로파 라디오미터의 최근 기술 및 요구사항에 대하여 서술한다. 최근의 지구 관측 위성에 운영되는 미션에 사용되는 마이크로파 라디오미터 시스템의 종류(total power, Dicke, NIR)와 관측하고자 하는 대상(imager, sounder)과 스캔방식(cross track, conical)에 따라 구분하고 설계 방법에 대하여 논한다. 또한 지구 관측 미션에 필요한 수동형 라디오미터 시스템에 필요한 요구사항에 대하여 최근 사용 및 개발 되고 있는 사례를 통하여 분석한다.
