Abstract

The stable fueling and water supply should be prerequisites to guarantee the operational sustainment of military command post. Meanwhile, in terms of the operational sustainment, it is verified that the current wave-guided below cutoff (WBC) system cannot satisfy the requirement of control associated with water supply and fueling within the command post. In this study, as the dielectric substance can block electromagnetic pulse (EMP), it was tried to identify the shielding effectiveness of the multi WBCs filled with water and diesel for attenuating the EMP effect using experiment based on the MIL STD 188-125-1. According to the experimental results, used water in the experiment show the shielding effectiveness from around 640 MHz frequency because of minerals contained in the water. Furthermore, it was noted that EMP attenuating strength of the WBC filled with diesel was enlarged from around 1,680 MHz frequency. Resultingly, it could be concluded that it is enough to supply stable water and diesel through the multi WBC to block EMP within the military command post for guaranteeing the military operations sustainment.

유사시 군 지휘시설에서는 시설 외부로부터의 수자원 및 에너지자원 공급이 차단 혹은 제한된다. 따라서 방호시설 내부에는 작전기간 중 필요한 충분한 양의 수자원 및 에너지자원을 확보하고 있어야 한다. 하지만, 전쟁양상의 변화는 시설내부에서 최소 2주 이상의 작전지속성을 요구하고 있다. 이러한 요구로 인하여 유사시에도 시설 외부로부터 내부로의 수자원 및 에너지자원 공급이 불가피하게 되었다. 이에 본 연구에서는 유전체 자체의 EMP 차폐 성능에 착안하여, 작전지속성 보장을 위한 충분한 급수/급유가 가능한 도파관 설치를 위하여 도파관 직경 및 유전체 종류에 따른 EMP 방호성능을 실험적으로 분석하였다. 실험을 통해 다중 도파관을 통해 효과적인 EMP 차폐와 동시에 군 지휘시설 내부로의 안정적인 급수/급유가 가능함을 확인할 수 있었다.
