Abstract

Due to rapid development of infrared guided weapon, survivability of armored vehicle is severely threatened. Hence, reduction of susceptibility by lowering infrared signature level is essential to enhance survivability of the vehicle. For this purpose, numerical analysis is conducted to analyze time and spatial characteristics of infrared signature of the vehicle when surface emissivity changes in this study. The analysis shows that the emissivity which produces minimum contrast radiant intensity is significantly altered by time and detecting position. Based on the result, it is concluded that the controlled structures which have different emissivity should be adopted at different region of the vehicle to effectively decrease infrared signature level.

적외선 유도 무기의 급속한 발달로 인해 현대 장갑 차량의 생존성은 크게 위협 받고 있다. 따라서 적외선 신호를 줄여 탐지가능성을 줄이는 것이 지상 장갑 차량의 생존성 향상을 위해 반드시 필요하다. 이러한 목적으로 본 연구는 수치해석을 사용해 차량 적외선 신호의 시간 및 탐지 위치별 특성을 분석하였다. 그 결과 가장 낮은 대비복사강도를 보이는 방사율이 시간 및 탐지 위치별로 상이하며 적외선 신호를 효과적으로 저감하기 위해서는 차량 부위별로 다른 방사율을 갖는 제어 구조를 적용해야 할 것이다.
