탐색기 고각 변화에 따른 함정 적외선신호 특성 분석

Abstract

IR(InfraRed) signature of a naval ship is composed of various signature sources. Contributions of typical IR signature sources has been investigated by numerical analysis using an analysis software, ShipIR/NTCS. Signature changes by an observer elevation have been analyzed through performing analysis for various observer conditions. IR signature of naval ships can be dramatically changed by observer elevation especially in a background with high temperature difference between air and sea. It is supposed that reducing ship skins contribution is very important in the night time condition also against high altitude threats.observer elevation have been analyzed through performing analysis for various observer conditions.
