Abstract

In this work, a new method to obtain the effective ground conductivity value in the middle frequency band where the informations of soil characteristics are insufficient was proposed. The proposed method obtained the effective ground conductivity values with the measured field strength from sea reference stations and general attenuation model in the middle frequency band. In addition, the proposed method used statistical method to minimize the error between the measurements and the predictions. Then, the effective ground conductivity in Korea peninsular was obtained by using the proposed method. Finally, it was verified that the effective ground conductivity using the proposed method is useful to predict electric field strength in the middle frequency band.

본 연구에서는 주변 환경이 복잡하고 토양의 특성이 잘 알려지지 않은 지역에서는 적용이 가능한 중파대역 유효 대지 도전율 계산법을 제안하였다. 제안된 방법은 해안 기지국에서 측정된 전계 강도와 일반적인 중파대역 감쇠 모델을 이용하여 유효 대지 도전율을 계산하며, 오차를 최소화하기 위해 통계적인 방법을 이용하였다. 다음으로, 제안된 방법을 이용하여 국내의 중파대역 유효 대지 도전율을 얻었으며, 전계 강도 비교 및 오차 분석을 통해 제안된 방법의 정확도와 유용성을 확인하였다.
