Abstract

The spectral irradiance of the Moon is used to monitor the performance of on-board satellite's visible channel detectors. This paper established a method to compute the spectral irradiance of the Moon using the relative positions between the Sun, Moon, and the COMS (Communication, Ocean, Meteorological Satellite), which is generated through the COMS FDS (Flight Dynamics Subsystem). The established computation method is applied to the algorithm which is developed to detect and compensate the degradations of COMS MI (Meteorological Imager) visible channel detectors.

달의 방사조도는 위성 가시채널 검출기의 성능을 감시하기 위해서 사용된다. 본 논문에서는 천리안위성 FDS (Flight Dynamics Subsystem)에서 생성한 태양, 달, 위성의 위치 정보를 이용하여 달의 방사조도를 계산하는 방법 및 결과를 설명한다. 계산 결과는 천리안위성 기상탑재체 가시채널 검출기의 성능저하를 검출하고 보상하기 위한 알고리즘에 적용되었다.
