Abstract

The spectral radiance received by an infrared (IR) sensor is mainly influenced by the surface temperature of the target itself. Therefore, the precise temperature prediction is important for generating an IR target image. In this paper, we implement the combined three-dimensional surface temperature prediction module against target attitudes, environments and properties of a material for generating a realistic IR signal. In order to verify the calculated surface temperature, we are using the well-known IR signature analysis software, OKTAL-SE and compare the result with that. In addition, IR signal modeling is performed using the result of the surface temperature through coupling with OKTAL-SE.

적외선 표적의 정밀한 모델링을 위해서는 정확한 표면온도 계산이 필요하다. 본 논문에서는 전도, 대류, 복사를 고려한 복합 열해석 모듈을 소프트웨어로 구현하고, 이를 통하여 표적 재질 및 자세, 환경 요건에 따른 표적의 표면온도 해석을 수행 하였다. 구현된 결과는 상용 소프트웨어인 OKTAL-SE 와의 비교를 통하여 결과의 신뢰성을 검증하였다. 그 결과 자체 검증이 완료된 상용 소프트웨어인 OKTAL-SE 와 약 1% 이내의 오차를 보였다. 계산된 온도 결과를 바탕으로 적외선 표적 모델링을 수행하였으며 OKTAL-SE와의 연동을 통해 적외선 신호 해석을 수행하였다.
