초록

적외선 신호는 대기에 의해 흡수, 산란 및 투과가 이루어지며 특정 파장대역에서 대기투과율이 높은 대기창이 존재한다. 따라서 대기투과율이 높은 파장대역에 따라 적외선 카메라들이 개발되고 있으며, 주변 온도, 상대 습도, 표적 특성, 표적과 배경의 온도차, 표적과의 거리에 따라 표적을 탐지할 수 있는 성능이 다르다. 본 논문에서는 대기투과 특성의 영향을 크게 받을 수 있는 하절기 및 동절기 해상환경에서의 중적외선 대역과 원적외선 대역의 적외선 카메라 탐지거리에 대해 분석을 진행하였다.

Abstract

Infrared signals are absorbed, scattered and transmitted by the atmosphere, there are wavelength regions where transmission is high. These regions are referred to as “atmospheric windows”. Infrared cameras are being developed depending on the atmospheric windows, The performance of infrared cameras differ under prevailing atmospheric conditions such as ambient temperature, relative humidity, target signature, target to background temperature difference and distance from target. In this paper, we analysis the detection ranges of the MWIR and LWIR bands in Summer and Winter Maritime Environments, which are greatly affected by atmospheric conditions.
