초록

함정에 있어서 레이더반사면적은 함정의 생존성과 직결되는 요소로써, 이에 대한 감소설계가 필요하다. 함정의 RCS에 영향을 주는 요소로써, 상부구조물, 함포, 레이더 등이 있다. 레이더의 경우 그 형상이 복잡하여 RCS 감소설계가 어려운 실정이다. 본 논문에서는 레이더의 RCS를 줄이기 위한 최신 기법 중의 하나인 폐위형 마스트에 대해 살펴보고 폐위형 마스트에 적용되는 주파수 선택 표면(Frequency Selected Surface: FSS)의 특성을 파악하였다. FSS의 형상에 따른 가용 가능한 주파수에 대해 일반적인 레이더와 폐위형 마스트의 RCS 비교를 통해 폐위형 마스트의 RCS 감소 성능을 확인하였고, 해석 고각별, 구조물의 경사별 RCS 해석을 통해 특성을 파악하였다. 일반적인 레이더의 경우 복잡한 형상으로 인하여 높은 RCS 값을 갖는 반면 폐위형 마스트의 경우 단순한 형상으로 인해 낮은 RCS 값을 갖는 것을 확인하였다.

Radar Cross Section (RCS) is a factor directly related to survivability, and a design to reduce the presence of this factor is needed. The upper structure, guns, radar and so on are related to warship RCS, but radar RCS reduction is difficult because of complex shapes involved. In this paper, an enclosed mast, which is one modern method for reducing radar RCS, and the characteristics of an applied Frequency Selected Surface (FSS) are analyzed. The RCS reduction ability of an enclosed mast has been confirmed by comparing RCS analysis results for a general radar with that of an enclosed mast for available frequency according to FSS shape. The characteristics of the enclosed mast have also been studied by analyzing the elevation angle and slope of the mast. General radar RCS was high because of its complex shape, but low RCS was shown for the enclosed mast model, which had a simpler shape.
