Abstract

In this paper, Radar cross section (RCS) calculations of advanced naval vessels model with RCS reduction methods are simulated and RCS results are discussed. Especially, this paper are mainly focusing on the facts influencing on RCS, the ways minimizing RCS and material characteristics of RCS changing-rate. RCS analysis results are given for a DDG-1000 type advanced naval vessels, which show that as the elevation angle increased 10 degree, the mean RCS value increased 23.91 dBsm. Also, as the superstructure angle increased 6 degree, the mean RCS value reduced 1.27 dBsm. Finally, the radar absorbing material attachment at the front and back superstructure have been reduced 2.27 dBsm in terms of mean RCS value.

본 연구에서는 첨단 함형에 레이더 반사면적 감소기술을 적용하고 특성을 분석하였다. 특히, 레이더 반사면적에 영향을 주는 요소, 레이더 반사면적을 최소화 하는 방안, 표적의 특수 재질 물성에 대한 레이더 반사면적의 변화 영향을 고찰하였다. DDG-1000 type 첨단 함형의 함정 고각별 레이더 반사면적 해석 결과 고각이 10도 높아짐에 따라서 RCS 평균값이 23.91 dBsm 증가하는 것을 확인하였다. 또한, 함정 상부구조물의 경사각이 6도 증가함에 따라서 RCS 평균값이 1.27 dBsm 감소하는 것을 확인하였다. 마지막으로 상부구조물 앞면과 뒷면에 전파흡수체를 부착한 경우 RCS 평균값이 2.27 dBsm 감소 하는 것을 확인하였다.
