초록

본 논문에서는 구축함에 탑재되는 통합 마스트의 RCS(Radar Cross Section) 값을 저감시키기 위해 다층 구조로 되어있는 유전체 코팅을 이용한 기법을 제시한다. 제시된 다층 구조는 특별히 고유전율을 요구하거나 전자기파 흡수 차단에 많이 사용되는 자성체성분을 포함하지 않은 일반적인 유전체를 사용할 수 있도록 유전율의 범위를 정했기 때문에 제작에 용이하다는 장점이 있다. 제시된 다층 유전체 구조를 통합 바스트 형상에 적용시킨 후 시뮬레이션을 진행한 결과 다층 구조가 없는 구조물과 비교하여 6GHz에서 10.9dB, 12GHz에서 11.95dB, 18GHz에서 11.63dB의 RCS 저감 성능이 있는 것을 확인하였다.

This paper presents a technique using a multilayered dielectric coating to reduce the radar cross section (RCS) value of an integrated mast mounted in a destroyer. The proposed multilayer structure has the advantage of being easy to fabricate because the dielectric constant is defined so that a general dielectric that does not contain a magnetic component that requires high dielectric constant or is frequently used for blocking electromagnetic wave absorption can be used. After applying the proposed multi-layer dielectric structure to the integrated mast shape, the simulation results show that the RCS reduction performance is 10.9dB at 6GHz, 11.95dB at 12GHz, and 11.63dB at 18GHz compared to the structure without the multilayer structure.
