초록

고고도 전자기 펄스(HEMP)의 상황은 고고도 핵폭발로 인해 발생한다. HEMP상황은 위협 레벨 조사(TLI)를 통해 HEMP 상황을 시뮬레이션 할 수 있다. 본 논문에서는 전술기동무선통신체계의 안테나 종류에 따른 유도 전압을 위협 레벨 조사로 측정 및 분석 하였다. HEMP의 영향을 받으면 전자 장비가 마비되거나 손상 될 수 있다. HEMP 방호 필터는 전원선 및 신호선용으로 상용화되어 있다. 그러나 안테나용 HEMP 필터는 상용화가 부족한 편이며 존재하더라도 낙뢰보호용으로 제작되어 있다. 안테나의 주파수와 종류에 따라 적절한 HEMP 방호 필터를 만들기 위해 유도 전압을 측정하고 외삽법을 통해 최대 유도 전압을 분석하였다. 측정 결과 HF, VHF, UHF 대역과 같이 주파수가 증가할수록 측정된 유도전압은 감소하는 것으로 나타났다.

The situation of high-altitude electromagnetic pulses (HEMP) arises from high-altitude nuclear explosions. The HEMP situation can be simulated through the threat level investigation (TLI). In this paper, the induced voltage according to the antenna type of the tactical mobile radio communication system was measured and analyzed by TLI. Under the influence of HEMP, electronic equipment can be paralyzed or damaged. HEMP protection filters are commercially available for power lines and signal lines. However, commercialization of HEMP filters for antennas is insufficient, and even some of them exist for lightning protection. In order to make an appropriate HEMP protection filter according to the frequency and type of the antenna, the induced voltage was measured and the maximum induced voltage was analyzed through extrapolation. It was found that the measured induced voltage decreased as the frequency increased, such as in the HF, VHF and UHF bands of the measurement results.
